Trans-Pecos Botany with Dr Mike Powell

Crime Pays But Botany Doesn't

Dr. Michael Powell is the curator of the Sul Ross Herbarium in Alpine, Texas and a proverbial wizard of West Texas Botany and Plants of the Trans-Pecos. In this episode we discussĀ 
how the endangered species act influenced the wariness of Texas ranchers and land owners, the current drought that Texas is in, describing new species of plants, the rock-daisies and cliff-dwellers of theĀ Perityle clade (Asteraceae), limestone endemism among Texas plants, how to propagate Texas Madrones, how chromosome-counting was done using immature buds before the advent of PCR, propagating rare native plants of the Trans Pecos, botanizing Mexico in the 1960s and 70s, gypsophile plants, and how a single teacher inspired him to ditch baseball for Botany in the early 1960s.

<v Speaker 1>Okay, welcome to the crime page, but Bodany doesn't podcast.
<v Speaker 1>I'm here today with the Texas botany legend, doctor Michael Powell,
<v Speaker 1>curator of the Soul Ross or Barium and uh botanist
<v Speaker 1>in Texas. How long have you been doing botany in Texas?
<v Speaker 1>Fifty years, sixty.
<v Speaker 2>Years, sixty some odd years?
<v Speaker 3>Yeah, so a long time, A long time.
<v Speaker 1>You've seen it, you've seen it all. Just come a
<v Speaker 1>little bit closer to my Okay, so, uh, yeah, I
<v Speaker 1>guess in that time, So you start when did you start? Then?
<v Speaker 1>That would be like early sixties, mid sixties.
<v Speaker 2>In nineteen sixty three, I guess is when I came
<v Speaker 2>to soul Ross. Uh.
<v Speaker 1>And how what brought you to West Texas.
<v Speaker 2>Baseball?
<v Speaker 1>Oh? Really? Is that what you is? That what you
<v Speaker 1>came to Suwaros for?
<v Speaker 2>That's right?
<v Speaker 1>Uh? And what made the what made you switch to bodany?
<v Speaker 1>What made you say I'm gonna do this instead? This
<v Speaker 1>is more interesting?
<v Speaker 2>Well, I was a majoring in physical education as an
<v Speaker 2>athlete playing basketball and baseball, and I took a class
<v Speaker 2>and plant tax on me under Barton Warnock. So that
<v Speaker 2>was to me, that was amazing learning about the plants,
<v Speaker 2>and all, and so that changed everything for me. So
<v Speaker 2>I decided to change my major and then get a
<v Speaker 2>master's degree right away, and then luckily I was asked
<v Speaker 2>to go get a pH d after that.
<v Speaker 1>So a single teacher pretty much kind of influenced.
<v Speaker 2>Yeah, teacher did. Yeah, he actually influenced several people before me.
<v Speaker 1>That's amazing.
<v Speaker 2>Go into botany.
<v Speaker 1>I wish so many more people were doing that. Switching atics. Yeah,
<v Speaker 1>I'll offence to athletics, but I think one's a lot
<v Speaker 1>more menthally rewarding. One feels a lot more mentally rewarding.
<v Speaker 1>So what was it about? Because Barton Warnock's a well
<v Speaker 1>known name in West Texas, Bondney too, what was it
<v Speaker 1>about him that made you switch?
<v Speaker 2>He was enthusiastic and went in the field all the time.
<v Speaker 2>He took students with him, especially me. I got to
<v Speaker 2>go with him. Marshall Johnston was here at the same
<v Speaker 2>time too, and he's a you know, he was a
<v Speaker 2>co author of the Manual of the Vascular Plants of
<v Speaker 2>Texas and a famous botanists and so anyway, I had
<v Speaker 2>had all of that those people to go to and
<v Speaker 2>cultivate your interests going in the field to me was
<v Speaker 2>amazing and learning species.
<v Speaker 1>Well was it just interacting with the land and.
<v Speaker 2>Yeah, exactly. And the topography here was something I never forgot,
<v Speaker 2>the Schwallon desert country. And then I just love to
<v Speaker 2>climb mountains and that sort of thing, and find new plants.
<v Speaker 1>In the endemics too, a ton of endemics out here,
<v Speaker 1>or plants that this is the only place in the
<v Speaker 1>United States that they grow. The rest of the populations
<v Speaker 1>in Mexico and back then too, I would imagine a
<v Speaker 1>lot of these species were not even named yet, right,
<v Speaker 1>This was kind of.
<v Speaker 2>This was the least investigated by home in North America.
<v Speaker 2>And then the Swaman Desert region anyway, and we're in
<v Speaker 2>the northern Schwaman Desert region here. Of course, most of
<v Speaker 2>it is in Mexico. As you know. The diversity was
<v Speaker 2>something else. Geological diversity is what fosters plant diversity. So
<v Speaker 2>this is the most diverse, biologically diverse biome in North America.
<v Speaker 2>It's Schwamann Deesert region.
<v Speaker 1>See the geology. You've got limestone which is prevalent all
<v Speaker 1>throughout Texas, remnants out of western Interior seaway, which is
<v Speaker 1>like early Cretaceous, right.
<v Speaker 2>Yeah, it's early Cretaceous.
<v Speaker 1>Yeah, and then you've got much younger volcanics and you
<v Speaker 1>get different casts of plant species on both those. There's
<v Speaker 1>a couple that will grow on both. But then there's
<v Speaker 1>so many limestone endemics too.
<v Speaker 2>The other endemics as well. Of course, through geological evolution,
<v Speaker 2>a lot of other kinds of exposures were formed, Like
<v Speaker 2>the gypsum exposure became a big deal for me. Oh
<v Speaker 2>yeah in the late nineteen sixties, starting about then, and
<v Speaker 2>this is a wonderful gypsum place here into Mexico.
<v Speaker 1>Yeah, all the way from Albuquerque down into Nuevo Leone.
<v Speaker 1>I mean the gypsummism I didn't really become familiar with
<v Speaker 1>until maybe twenty nineteen.
<v Speaker 2>It goes farther in Mexico than Uev Leone too, and
<v Speaker 2>into San Luis bodesee Zakitacus.
<v Speaker 1>Were you going down to Mexico a lot?
<v Speaker 2>Yeah, a lot, yes, mostly in other kinds of pursuits
<v Speaker 2>at the time. Monographing composite genera is what I was doing.
<v Speaker 1>So Asta RASI especially was your specialty. I know you
<v Speaker 1>worked on paridally for a while. What was it about,
<v Speaker 1>And we'll get to that later, But what was it
<v Speaker 1>about Asta Raci that really struck you? Because it's a
<v Speaker 1>family that, as you know, you taught botany, so many
<v Speaker 1>students are just like nah, but when you really learn
<v Speaker 1>about it, it's utterly fascinating.
<v Speaker 2>Yeah. It's the largest family of flowering plants, of course.
<v Speaker 2>And that's where I started at UT. My PhD assignment
<v Speaker 2>was a Mexican a monograph of Mexican genus that was
<v Speaker 2>extended into South America. But that's where it got started,
<v Speaker 2>and my major professor had a an NSF grant to
<v Speaker 2>do chromosome numbers and do other kinds of studies and
<v Speaker 2>Asta race It turns out that there were other centers
<v Speaker 2>for Asta racey studies at the same time in California,
<v Speaker 2>at the Smithsonian for example, so they were all doing
<v Speaker 2>chromosome numbers. So anyway, that's what I did in Mexico
<v Speaker 2>was do my tried as collecting field investigations, and at
<v Speaker 2>the same time I was collecting plants for my major professor,
<v Speaker 2>bl Turner.
<v Speaker 1>Yeah, okay, I want to talk about him too, because
<v Speaker 1>he's another name. I mean, yeah, all these names, Warnock, Turner, Powell.
<v Speaker 1>I mean, when people think of wests, you know, United
<v Speaker 1>states Chiuhaiwan does her botany, your name comes up like
<v Speaker 1>you're famous, man, you are so, but yeah, deservedly so so.
<v Speaker 1>But let's talk about the chromosome work, because you were
<v Speaker 1>doing botany at a time before the advent the PCR
<v Speaker 1>and and all the molecular work that's being done now,
<v Speaker 1>which must have been hard. I mean, that's I think
<v Speaker 1>back to those times, like no GPS, no molecular work,
<v Speaker 1>I mean, and you guys were still going out there,
<v Speaker 1>I mean, no digital cameras too, like you had. I
<v Speaker 1>remember seeing a picture of Barton Warnock with like an
<v Speaker 1>old school film camera, and I just I can't imagine
<v Speaker 1>what that must have been. Like I'll take twenty photos
<v Speaker 1>of the same plant sometimes before I get one. I like,
<v Speaker 1>so what, I guess I want to talk about all that,
<v Speaker 1>like the going out of the field then and then
<v Speaker 1>also doing chromosome work. I guess I's start with the
<v Speaker 1>chromosome work first. What what's that about and what did
<v Speaker 1>that entail?
<v Speaker 2>Well, it was ah with that asteras or composite chromosome numbers,
<v Speaker 2>because there's so many in the first place. Everybody was
<v Speaker 2>realizing that chromosome numbers were important in composite taxonomy, and
<v Speaker 2>there were few chromosome numbers known at the time, so
<v Speaker 2>there were people that were doing that almost exclusively, a
<v Speaker 2>few people anyway, and so I joined the crowd, was
<v Speaker 2>invited to join some of the crowds I was involved
<v Speaker 2>in at the time in four chromosome number series that
<v Speaker 2>were being developed. You know, people doing series of chromosome
<v Speaker 2>number papers where the papers would include tables of the
<v Speaker 2>chromosome numbers, the number of species and their chromosome numbers,
<v Speaker 2>and then the text would include what was important about
<v Speaker 2>those chromosome numbers and with respect to the taxonomy at
<v Speaker 2>the time.
<v Speaker 1>So this was this was not just plody levels, but
<v Speaker 1>number of chromosomes.
<v Speaker 2>Ye, well there if you do there's here's a thing
<v Speaker 2>about that too. With plants, we can do myotic chromosome observations.
<v Speaker 2>So it's more than chromosome numbers, it's myotic chromosome behavior,
<v Speaker 2>which tells a lot about the relationships of plants and
<v Speaker 2>the the direction of chromosome number change because of myotic
<v Speaker 2>chromosome behavior. Of course, more important, I guess than that
<v Speaker 2>is as ploity levels, you know, whole genome changes and
<v Speaker 2>chromosome numbers.
<v Speaker 1>So how would you how would you figure these out
<v Speaker 1>without molecular analysis? What what would it entail?
<v Speaker 2>What would well look under a microscope? The technique is
<v Speaker 2>fairly simple with composites and other kinds of plants, and
<v Speaker 2>we got into all the other kinds of plants later
<v Speaker 2>on here at so OSS anyway, but what it involves
<v Speaker 2>is picking buds in early stages of myosis and putting
<v Speaker 2>in in vials of fixative that one takes with them
<v Speaker 2>in the field. So if I were going in the
<v Speaker 2>field for a week or two weeks or a month,
<v Speaker 2>I would prepare in advance a number of these chromosome
<v Speaker 2>number of vials with the fixative in them files about
<v Speaker 2>I don't remember how many milliliters of fixative that they had.
<v Speaker 2>And then you would when you encounter these species in
<v Speaker 2>the field and you picked the buds from the plants.
<v Speaker 2>You have to take a number of buds, of course,
<v Speaker 2>because you can't anticipate the correct stage of myosis, so
<v Speaker 2>you want to get them while you're there. And I'd
<v Speaker 2>have to go back several hundred miles or several.
<v Speaker 1>Thousands at different staably.
<v Speaker 2>Oh yeah, indeed, at different stages. Yeah, So anyway, we're
<v Speaker 2>going to get back to the laboratory. Then this is
<v Speaker 2>a compound microscope thing. So it is the technique involves
<v Speaker 2>taking the young buds which are in early stages of myosis,
<v Speaker 2>and you don't know what stage that is until you
<v Speaker 2>make the preparation. And the preparation is on a microscope
<v Speaker 2>slide in a DNA specific stain acetocarmine. It's a carmine
<v Speaker 2>stain to be specific. And so anyway, if there's a
<v Speaker 2>maceration technique with a glass rod and removing all of
<v Speaker 2>the debris and making a what's called a miotic squash,
<v Speaker 2>it's called a miotic squash technique where one flattens these
<v Speaker 2>things so we can, if we have the right stage,
<v Speaker 2>see the chromosomes and a narrow plane of focus, so
<v Speaker 2>we can focus and actually see the chromosomes in a
<v Speaker 2>miotic stage and count the number. It's just that simple.
<v Speaker 1>God, that's incredible. So, how what magnification are youse? A
<v Speaker 1>thousand necks or more than that?
<v Speaker 2>We use oil immersion lin so it's uh and depending
<v Speaker 2>on the ocular in the ocular magnification and the hundred
<v Speaker 2>times magnification of a of an oil immersion LINS, so
<v Speaker 2>it's several thousand, so.
<v Speaker 1>You but it's just wild that you can see the chromosomes, that's.
<v Speaker 2>Yeah, in different stages. You see different stages, so you
<v Speaker 2>can follow the behavior of the chromosomes pairing behavior, yeah,
<v Speaker 2>homologous chromosome behavior. You can see the effects of structural
<v Speaker 2>rearrangements like rings of four, like univolence. So all of
<v Speaker 2>that is apparent under a microscope and you're good at it.
<v Speaker 1>And so you'd get the buds before the flowers opened,
<v Speaker 1>because that's yes, in the bud stays, that's when the
<v Speaker 1>plants are undergoing milsis that's correct, and producing half loid sporangia,
<v Speaker 1>So that's.
<v Speaker 2>They're on the way to doing that anyway. And this
<v Speaker 2>is a this is a microspore mother sells microsporocytes. So
<v Speaker 2>it's if you imagine the amount of pollen that is
<v Speaker 2>ultimately produced the myotic cells. Each each microsporocite produces four
<v Speaker 2>ultimately produces four pollen grains through myosis. So there are
<v Speaker 2>a lot of cells to work with in the in
<v Speaker 2>the anthers, young anthers undergoing myosis.
<v Speaker 1>And so you were using what you were using this
<v Speaker 1>for taxonomy presumably, and.
<v Speaker 2>Yes, it's systematic pursuing systematics taxonomy. That's right.
<v Speaker 1>Yeah, and so you said you were working with trite
<v Speaker 1>acts before. I know that. That's it's a native to
<v Speaker 1>lower latitude North America. I mean it's now it's like
<v Speaker 1>a weed all over. It's been very successful, and you
<v Speaker 1>know it is a ruterural plant with human development. It
<v Speaker 1>benefits from from human development. But it's a really I
<v Speaker 1>mean I've seen it where it grows native. I saw
<v Speaker 1>it in the Dominican Republic, like growing on a rock
<v Speaker 1>out crop, behaving like a native plant, like it like
<v Speaker 1>it would. What was it, tritex pro commins you were
<v Speaker 1>working with, or well.
<v Speaker 2>That's one of them. It's it's actually a weedy species
<v Speaker 2>in Mexico, but a lot of.
<v Speaker 3>Them are not weeds.
<v Speaker 2>Yeah, they have pretty narrow distributions in Mexico.
<v Speaker 1>So this is a big genus.
<v Speaker 2>Oh, it's not a huge genus. About twenty five species,
<v Speaker 2>I think.
<v Speaker 1>So what what was I guess what what did you
<v Speaker 1>find exciting about that genus? Specifically what druids were.
<v Speaker 2>Well, we were able to recognize two subgenera because of
<v Speaker 2>chromosome numbers, for one thing, and then that leads you
<v Speaker 2>to closer examination of morphology, just like modern DNA sequencing
<v Speaker 2>data do today. You can look back and after you
<v Speaker 2>know the living the phylogenetic relationships, and see morphological characters
<v Speaker 2>that one didn't realize the significance of initially.
<v Speaker 1>Yeah, and so you'd realize these are two different clades
<v Speaker 1>within the same genus.
<v Speaker 3>Exactly.
<v Speaker 1>There was some divergence event, however, for exactly what was
<v Speaker 1>what was traveling in Mexico like back then? I mean,
<v Speaker 1>it was probably a lot safer than now, but also
<v Speaker 1>you know, a lot more rugged too.
<v Speaker 2>Well, it was much safer than it is now. But
<v Speaker 2>after you get farther south in Mexico, we were still
<v Speaker 2>advised not to camp out, so I'm we stayed in
<v Speaker 2>motels all the time. But traveling in Mexico was no
<v Speaker 2>problem at all as far as I'm concerned. Yeah, and
<v Speaker 2>every time you're dealing with the people, it was a
<v Speaker 2>wonderful experience. Yeah, no problems at all. I didn't speak Spanish,
<v Speaker 2>but I just spoke a little bit of Spanish and
<v Speaker 2>I was working on Spanish all the time. Never learned
<v Speaker 2>to speak Spanish, yeah, but I always tried because I
<v Speaker 2>was in Mexico and everybody seemed to appreciate that, and
<v Speaker 2>so they would start speaking English so we could communicate.
<v Speaker 1>So you guys would be just rolling down there with
<v Speaker 1>a crew of what like four or five bodanists and.
<v Speaker 2>Two people men another person. That's the way you always went.
<v Speaker 1>And you went down there with Billy Turner quite a
<v Speaker 1>few times.
<v Speaker 2>Go down first with another person who agreed to go
<v Speaker 2>with me. He was that person I met at Sows.
<v Speaker 2>Actually he was a baseball player and it was from
<v Speaker 2>from the Houston area, but and he went back and
<v Speaker 2>went to school at San Marcos at Southwest Texas State
<v Speaker 2>it was called in Texas State now, But he agreed
<v Speaker 2>to go with me for a month in Mexico when
<v Speaker 2>I was so glad about having a gaudry along.
<v Speaker 1>Did he ever make the switch from baseball to botany.
<v Speaker 2>No, he didn't. He was from Mathis originally, and so
<v Speaker 2>he really got into he was got into natural naturalists
<v Speaker 2>a little bit.
<v Speaker 1>You know, so he's starting with it a little bit.
<v Speaker 2>I mean, yeah, a little bit he did.
<v Speaker 1>I'm still just amazed that, I mean, because that's such
<v Speaker 1>a change. I'm sorry to go back to this, but
<v Speaker 1>from baseball to natural sciences, that's got I'd love that
<v Speaker 1>it's bad teacher.
<v Speaker 2>Well, that's that's right. I guess I was always an
<v Speaker 2>outdoorsman when I was a kid, mm hmm, cunning and fishing,
<v Speaker 2>that sort of thing, and so I love the out
<v Speaker 2>of doors anyway. But it's a it's a combination of
<v Speaker 2>the of the topography and all the countryside and plants.
<v Speaker 2>I guess. Plants are marvelous. There's always something interesting about them. Yeah,
<v Speaker 2>never run out of interest, at least in this area.
<v Speaker 1>I think for people that aren't into botany, it's still
<v Speaker 1>really hard to not love West Texas. You like to
<v Speaker 1>enjoy spending time on here. I mean there's so much
<v Speaker 1>and especially I mean going to Mexico back then too,
<v Speaker 1>like watching the landscape change from high and dry to
<v Speaker 1>more you know, tropical, you know, dry deciduous forests. Like
<v Speaker 1>when you go further enough south. Yeah, I mean like Quatrisiegasa,
<v Speaker 1>all these, all these when you when you leave south
<v Speaker 1>out of you know, the Big Bend region, I can
<v Speaker 1>only imagine it gets really interesting. You start seeing species
<v Speaker 1>that we don't get up here. Yes, indeed, let's talk
<v Speaker 1>about your work with peridally, because the rock daisies, it's
<v Speaker 1>the you know, most of them. There's a few terrestrial species,
<v Speaker 1>but most of them grow out of vertical cliffs. There's
<v Speaker 1>a lot of microinthemics tool that only grow. You know,
<v Speaker 1>this species of peridally grows in this region, and then
<v Speaker 1>fifty miles away, even thirty miles away, you get a
<v Speaker 1>whole other species of paridally that's you know, completely different.
<v Speaker 1>What how when did you start working on paridally and
<v Speaker 1>what attracted you to it?
<v Speaker 2>Well, when I came here from Austin, I was looking
<v Speaker 2>for another genus to monograph, because that's what that was
<v Speaker 2>the ultimate and systematic botany at the time. And then
<v Speaker 2>of course I started with composits, so I wanted to
<v Speaker 2>continue with the composits. And parially I knew from here,
<v Speaker 2>you know, a couple of species or a few species,
<v Speaker 2>and so I looked into it and it turned out
<v Speaker 2>it's a widespread genus in the southwestern United States and
<v Speaker 2>Mexican go and there were a lot of species, and
<v Speaker 2>so that looked to me like it would gain National
<v Speaker 2>Science Foundation grant support. So I wrote a proposal to
<v Speaker 2>the National Science Foundation and got funded luckily the first year,
<v Speaker 2>just really lucky to do that, because it's hard to
<v Speaker 2>do but had some good people in my background, I think,
<v Speaker 2>to help out, and some product too. You have to produce,
<v Speaker 2>and so I'd already started publishing by then, and so
<v Speaker 2>that's impressive to people at the National Science Foundation. So
<v Speaker 2>I got funded and off I went. So I guess
<v Speaker 2>that lasted for about I think it was nearly ten
<v Speaker 2>years of grant support for monographing Paridley took me all over.
<v Speaker 1>You were going all over West Texas, Mexico.
<v Speaker 3>All over the southwest Arizona, because these are the.
<v Speaker 2>Arizona, Nevada, Utah. They curved for it as far north
<v Speaker 2>as the Salt Lake City.
<v Speaker 1>Lake.
<v Speaker 2>There's a there's a Pirelli Stansbury Eye on the margins
<v Speaker 2>of the Great Salt Lake and then down through California,
<v Speaker 2>Nevada and California, but the Preleys are east of the
<v Speaker 2>of the Sierra Nevadas. But all the way down through
<v Speaker 2>the south part and in the Baja California, and then
<v Speaker 2>in New Mexico.
<v Speaker 1>They specialize in dry areas.
<v Speaker 2>Basically, well not always they're in they're in high mountains too,
<v Speaker 2>you know eight thousand feet approximately that there's a species.
<v Speaker 2>It's only in the annual mountains in the California about
<v Speaker 2>eight a little over eight thousand feet in ensis is there,
<v Speaker 2>so in Mexico and the high mountains too, and other
<v Speaker 2>high mountains and uh in Arizona for example, But that
<v Speaker 2>evidently there they undergo geographic speciation. And so, as you
<v Speaker 2>mentioned while ago, every isolated mountain range, every isolated bluff
<v Speaker 2>rock formation, they're likely to be a different taxon of brittle.
<v Speaker 2>So that was fun investigating all those new habitats in
<v Speaker 2>different areas. It's a lot of work because they're not
<v Speaker 2>on every bluff.
<v Speaker 1>I bet they're like Darwin's finches in that.
<v Speaker 3>Regard, Yeah, sort of like that.
<v Speaker 1>Yeah, see this, I mean you can't see the specialization
<v Speaker 1>like you could in the beaks of Darwin's finches, but
<v Speaker 1>you know it's the unique species that in the same
<v Speaker 1>genus that are, you know, not so far apart from
<v Speaker 1>each other. I remember seeing pretty vandavenduri, that rare one
<v Speaker 1>in Sonora. We met then tell that day. That was
<v Speaker 1>kind of terrifying, but they were they were nice to us.
<v Speaker 2>But that's after our tales were after me, thank goodness.
<v Speaker 1>Yeah. Yeah, the so what was so Texas is mostly
<v Speaker 1>private land and so how are you getting access to
<v Speaker 1>most of these places. It was probably a lot more
<v Speaker 1>lax back than this is what late sixties, early seventies.
<v Speaker 2>Yeah, in that time, ranchers were proud of what they
<v Speaker 2>had on their land, and if there was an unusual
<v Speaker 2>species there, they wanted to know about it, and so
<v Speaker 2>they took care of it and protected it and just
<v Speaker 2>wanted to know what was there so we could gain access.
<v Speaker 2>But frankly, when early on, a lot of my access
<v Speaker 2>was because of Barton wan Hawk, because he knew of
<v Speaker 2>the ranchers and he could help you get access to
<v Speaker 2>various places. But there were places we couldn't get access to,
<v Speaker 2>and that's always been a problem.
<v Speaker 1>Some people just weren't having it.
<v Speaker 2>They just didn't, Yeah, and you couldn't get in contact
<v Speaker 2>with people. Sometimes there was some you know, the landlorders
<v Speaker 2>were the owners were somewhere else, and there were people
<v Speaker 2>that weren't authorized again give permission for access. Yeah, so
<v Speaker 2>eventually that could happen. Eventually you could find some way
<v Speaker 2>a friend knew a friend or something like that.
<v Speaker 1>What is the there's a parially east of El Paso
<v Speaker 1>and Waco tanks? Is that? What is it Prey? What
<v Speaker 1>is it Hawaco?
<v Speaker 3>Inces that's correct.
<v Speaker 1>Have you seen that one that's a super that's.
<v Speaker 2>The one I described?
<v Speaker 1>Yeah, that is the one you described, well, one of them,
<v Speaker 1>one of them? Yeah, yeah. How many species of plants
<v Speaker 1>have you described?
<v Speaker 2>I don't know. There's quite a few, I guess, counting
<v Speaker 2>chips of philes and uh yeah, Mexicum species and several
<v Speaker 2>general I don't I don't keep up with that.
<v Speaker 1>And you wrote the flora of the trans peoples too, yes,
<v Speaker 1>of course, yeah, which is a massive, beautiful tone. So
<v Speaker 1>that parial Waco instance, What was the story with that?
<v Speaker 1>How did you find that? How did did how did
<v Speaker 1>you come across it?
<v Speaker 2>Just going places and looking in different rock formations?
<v Speaker 1>This good feel body, you knew, the habitat you knew, yeah,
<v Speaker 1>oh yeah.
<v Speaker 2>And it takes a while to get all all these
<v Speaker 2>places and find things. But in several years, you don't
<v Speaker 2>ever see everything any one time you go in the
<v Speaker 2>field because are different climatic conditions at the time, different
<v Speaker 2>flowering times and that sort of thing. So you learn
<v Speaker 2>this through trial and arrow over periods of time.
<v Speaker 1>Regarding the climatic conditions West Texas is, I mean, we're
<v Speaker 1>in a drought right now. It's super dry, and it's
<v Speaker 1>been You know, rains can be hit or miss. The
<v Speaker 1>rainfall pattern here is really bizarre. Spring is generally always
<v Speaker 1>pretty windy and dry, and summer monsoons are what the
<v Speaker 1>region relies on. Hey, how have you seen the landscape
<v Speaker 1>change since you've been here?
<v Speaker 2>It's getting drier And I don't know what else to
<v Speaker 2>say about that. The landscape has changed because plants die.
<v Speaker 2>And this is mostly in recent years in my experience anyway,
<v Speaker 2>there are more juniverse, more invasive plants, more plants dying
<v Speaker 2>in recent years, getting drier all the time. It seems
<v Speaker 2>like it's just it's just an observation, it's not scientific.
<v Speaker 1>Well, you've mentioned, I mean, large oaks dying, even juniper's
<v Speaker 1>dying in some cases. I was talking with Deb yesterday
<v Speaker 1>she had mentioned that, you know, even Koreosot's starting to
<v Speaker 1>die in the park. I know, you know, rainfalls always
<v Speaker 1>hit or miss, but this seems more like a prolonged
<v Speaker 1>like a more prolonged rout. Right.
<v Speaker 2>Of course, dryness has been going on for some time.
<v Speaker 2>The Shewahen Desert has been moving north then expanding in territory.
<v Speaker 2>If we if we wanted to look back fairly scientifically. Luckily,
<v Speaker 2>we have some good, good data going back to since
<v Speaker 2>the last ice Age, at least from packrat middens. And
<v Speaker 2>this was done early on by a person from Kansas,
<v Speaker 2>Philip Wells, and then he published a paper or two
<v Speaker 2>on that, and he moved west a little bit. But
<v Speaker 2>then that was really enhanced by Tom Van Devender you
<v Speaker 2>mentioned a while ago in a specific epithet, who's a
<v Speaker 2>famous botanist in Arizona, and he he did some early
<v Speaker 2>studies and with back right middens in Arizona, Mexico and
<v Speaker 2>here as well. So we have a lot of paleological
<v Speaker 2>information from the middens, so we know what the We
<v Speaker 2>have a good idea of what the conditions were like
<v Speaker 2>eight eight, ten thousand years ago when there were woodlands
<v Speaker 2>all the way south into Big Ben National Park, for example,
<v Speaker 2>and then New Mexico. So we know it's been getting
<v Speaker 2>dryer all the time.
<v Speaker 1>Yeah, But in.
<v Speaker 2>We keep weather records like anybody does, I suppose, and
<v Speaker 2>I've been keeping them since since the nineteen I suppose,
<v Speaker 2>and it's and it seems it just seems that things
<v Speaker 2>are getting drier, and it's it's pretty clear for the
<v Speaker 2>last thirty years or more.
<v Speaker 1>Yeah, and of course, I mean there were megadroughts in
<v Speaker 1>the around twelve hundred, you know, whatever drove the Anisazi
<v Speaker 1>out of their cliff dwellings or as likely to have.
<v Speaker 1>So this is a I mean, this happens, but it's
<v Speaker 1>certainly it doesn't spell. It doesn't. It doesn't look good
<v Speaker 1>when you've got a large human population. Aquifers are dropping.
<v Speaker 1>There's just way more human impact, and all the habitats
<v Speaker 1>carved up to into development or non development or agriculture
<v Speaker 1>whatever the pack rat middens, you know. I mean you
<v Speaker 1>look at places like the Cheeseaus Mountains, which is a
<v Speaker 1>sky island, or the Davis Mountains, another sky island, and
<v Speaker 1>there's plants that grow there that don't obviously occur in
<v Speaker 1>the hotter lowland areas, and then you start thinking, well,
<v Speaker 1>how they get there? I guess it could be birds,
<v Speaker 1>but it's more likely that there was a contiguous population
<v Speaker 1>that occurred much lower down. And then, as you know,
<v Speaker 1>the post place to see drying and warming, this stuff
<v Speaker 1>starts moving up. I think that kind of stuff is
<v Speaker 1>wild to think about, you know that watching a landscape
<v Speaker 1>change over a few thousand years and then seeing these
<v Speaker 1>clues that kind of hint at it. What regarding these skylands,
<v Speaker 1>like the Cheeseos and the Davis, there's an you've obviously
<v Speaker 1>probably done a lot of work in both those places.
<v Speaker 2>I've climbing around there.
<v Speaker 1>Yes, there's I mean you get our Beutis halapenses, which
<v Speaker 1>is the you know, a madrone which you see in
<v Speaker 1>Mexico and cloud forests and pine oak forests, and then
<v Speaker 1>to see it here. I mean if I remember finding
<v Speaker 1>two trees in this wash in a really really dry
<v Speaker 1>area that were just remnants. They were large trees and
<v Speaker 1>no seedlings, and they're hanging in there. Half of them
<v Speaker 1>might be dead, but you see that and you really
<v Speaker 1>start to think, wow, this is you know, what did
<v Speaker 1>this place look like the thousand, two thousand years ago?
<v Speaker 1>It's wild to think about the sky islands act Is refugia.
<v Speaker 1>What are some notable species that that you find really
<v Speaker 1>interesting and that you you know, would encourage people to
<v Speaker 1>focus on in both the Cheeseos and the Davis. I mean,
<v Speaker 1>you got archdol stapfelos pungings up there in the Davis Mountains.
<v Speaker 1>I didn't I didn't even know that. I just found
<v Speaker 1>that out our beautis these Oaksquircus rugosa, like really really
<v Speaker 1>cool species that seem way out of place in West Texas.
<v Speaker 2>There are oaks and pines and the Arizona cypress Suda
<v Speaker 2>sugar men cazi, which is Douglas fir. Yeah, that's in
<v Speaker 2>certain places Douglas fur in the Guadaloupes and in the Cheeseos,
<v Speaker 2>but not in the Davis Mountains for some reason. And
<v Speaker 2>these are oliqual populations apparently, is it would seem anyway
<v Speaker 2>from what data are available, so oaks and pines and
<v Speaker 2>maybe some other things that aren't coming to mind.
<v Speaker 1>Now.
<v Speaker 2>I've seen the arch estaphlis. It's in one big population
<v Speaker 2>in the in the eastern Davis Mountains, and then it's
<v Speaker 2>scattered around in another place or two in the Eastern
<v Speaker 2>Davis Mountains, but maybe somewhere else as well. Yeah it
<v Speaker 2>may it may have once been in the Cheesos Mountains,
<v Speaker 2>but evidently it's not there now.
<v Speaker 1>I wonder, you know, with stuff like that, I wonder
<v Speaker 1>how much divergence would be you'd be able to see,
<v Speaker 1>you know, if you did like whole genome sequencing comparing
<v Speaker 1>that population with one further south, and you know, saying
<v Speaker 1>the way will lay one. You know, I guess it
<v Speaker 1>would only be what twenty thirty thousand years divergence maybe,
<v Speaker 1>What do you think?
<v Speaker 2>Well, evidently there is some of that going on or
<v Speaker 2>has been going on there. I've noticed and say, in
<v Speaker 2>the recent years, there have been some Ponderosa Pine experts
<v Speaker 2>it has been doing molecular work with bond rosis, and
<v Speaker 2>evidently there are some genetic differences between these populations, and
<v Speaker 2>there's some early genetic evidence that there's more than one
<v Speaker 2>genetic lineage in a Cheeseo's mountains alone. I've seen that
<v Speaker 2>in a fairly recent paper.
<v Speaker 1>That's why.
<v Speaker 2>So I don't know that that's been followed up. And
<v Speaker 2>a lot of the preliminary DNA work has been done
<v Speaker 2>with chloroplasts, and some of that is fairly suspicious because
<v Speaker 2>of the way chloroplasts may be inherited. Yeah, right is Yeah,
<v Speaker 2>in chloroplast capture and through hybridization is also a possibility.
<v Speaker 1>It's a it's a cool thing to think about. It's
<v Speaker 1>fun to think about because obviously the environment is still
<v Speaker 1>selecting in even if it's only twenty thousand years divergence,
<v Speaker 1>Like the environment in one place is selecting slightly differently
<v Speaker 1>and the environment in another place. So I mean still
<v Speaker 1>saying species just different ecotized. But it's really really interesting
<v Speaker 1>stuff to think about. Regarding the Davis Mountains, What interesting
<v Speaker 1>things have you found there or encountered there, because that's
<v Speaker 1>a mysterious that's kind of mysterious area. It's really hard
<v Speaker 1>to get access.
<v Speaker 2>Yes, it is. My first access was through the Davis
<v Speaker 2>Mountain Resort, which is a development on the or sort
<v Speaker 2>of on the southern slopes, and we could gain access
<v Speaker 2>that direction anyway with a little secondary permission or two.
<v Speaker 2>That's for the highest elevations at Mount Livermore anyway. So
<v Speaker 2>there are some say I'm trying to think there's a
<v Speaker 2>there's some rare oaks on the at the near the
<v Speaker 2>top of Mount Livermore if there of course a southwestern
<v Speaker 2>white pines are there. And what is that pseudostrobus uh
<v Speaker 2>that is a pinas strubble offormis yes, yeah, And some
<v Speaker 2>relitual populations of of populous tremuloidies that quaking aspen are there.
<v Speaker 1>That's wild.
<v Speaker 2>Some high elevation salvias are there a viola uh, things
<v Speaker 2>like that.
<v Speaker 1>What are the salvias that are out there?
<v Speaker 2>Salvia Arizonica comes to mind. Wow, a blue flowered salvia.
<v Speaker 1>And I assume there's all collections of this stuff in
<v Speaker 1>the herbarium here.
<v Speaker 2>Yeah, they have collections of all that.
<v Speaker 3>Yeah, do you.
<v Speaker 1>I guess I want to come back to this at
<v Speaker 1>some point because the Sky Island stuff is really fascinating.
<v Speaker 1>But the herbarium, I mean, this is I love this erbarium.
<v Speaker 1>This is one of the best in Texas. The other
<v Speaker 1>one is at Austin, the other large one. I guess
<v Speaker 1>Alpaso has one. But herbaria are almost becoming an endangered
<v Speaker 1>species themselves in some cases. I mean they're being closed
<v Speaker 1>or you know. I know Rio Grand Valley UTRGV had one.
<v Speaker 1>It was in what was essentially a janitorial closet and
<v Speaker 1>a lot of the specimens were damaged. And I had
<v Speaker 1>a friend who was working there scanning them. He's like,
<v Speaker 1>I'm just digitizing them and sending him to Austin. We
<v Speaker 1>got a grant to do this. I think the school
<v Speaker 1>may have even maybe the school paid for it, and
<v Speaker 1>I think it might have been a stepping stone for
<v Speaker 1>them to be like, we've digitized it. Let it. You know,
<v Speaker 1>who knows what happens to you whatever.
<v Speaker 2>What?
<v Speaker 1>Yeah, I guess what are some of the other good
<v Speaker 1>or barrier in Texas? And what do you see? I
<v Speaker 1>guess what's the importance of collecting plants?
<v Speaker 2>Oh? Plants or plant collections are fundamental in botany. Without them,
<v Speaker 2>we were almost lost. We got to have the voucher
<v Speaker 2>specimens for chromosome counts, for example, voucher specimens for DNA work.
<v Speaker 2>They have to have the collections throughout populations to see
<v Speaker 2>variation and populations before species can be understood and described,
<v Speaker 2>or before we can know taxonomy or lineage of plants,
<v Speaker 2>before we can know times of flowering and all kinds
<v Speaker 2>of things that were happening back when they were when
<v Speaker 2>they were first collected. The largest iberium in Texas is
<v Speaker 2>at at brit Botanical Research Institute of Texas.
<v Speaker 1>Oh wow, I thought it.
<v Speaker 2>Was about over a million four specimens at brit.
<v Speaker 1>Apologies to Brit, I forget to mention you been there before. S.
<v Speaker 2>The second largest siberium is at UT Austin. They're over
<v Speaker 2>a million, well over a million specimens there.
<v Speaker 1>So it's I mean, obviously the importance of of of
<v Speaker 1>herbaria is keeping a record phenological data, noticing phenological changes,
<v Speaker 1>seasonality changes, and also I think with how much development
<v Speaker 1>is going on in some of the higher population density
<v Speaker 1>areas of this state, it's some of these populations might
<v Speaker 1>not be around and even a decade or two they
<v Speaker 1>might be wiped out. And so having a record, I
<v Speaker 1>mean that upo me anti Cyphialitica from South Texas alone,
<v Speaker 1>I've watched that population get destroyed for a solar farm.
<v Speaker 1>I mean, that's a really unique species to be. You know,
<v Speaker 1>that's and especially that it might be two species within
<v Speaker 1>anti Syphilitica. Nathan Taylor was saying it's and he's right.
<v Speaker 1>You look at the flowers on the South Texas population
<v Speaker 1>compared with the West Texas population, they're completely different. Certainly
<v Speaker 1>they probably weren't subspecies status and the rest of that
<v Speaker 1>he mapped it out and was showing that the rest
<v Speaker 1>of that South Texas Anti Syphilitica population is in Mexico
<v Speaker 1>and now it's gone. So you know, they're the two
<v Speaker 1>or barium records one I was able to collect are
<v Speaker 1>the only remnants that show that species was ever there.
<v Speaker 1>So do you do you see your barrier? Do you
<v Speaker 1>see them as slightly threatened in the future.
<v Speaker 2>They're threatened in a few places because of financial problem,
<v Speaker 2>but I think they're mainly threatened by people that take
<v Speaker 2>care of them.
<v Speaker 1>M m.
<v Speaker 2>That's the most important thing.
<v Speaker 1>You need a good curator. I remember when I first
<v Speaker 1>when I first came to this or Bury, it wasn't
<v Speaker 1>been two or three years ago. You were very meticulous
<v Speaker 1>about showing me how to handle them. You were like,
<v Speaker 1>I'm gonna make sure this guy remembers and it was
<v Speaker 1>pretty cool. So now I like, now it's in my
<v Speaker 1>head too. Every time I'm in any herbarium, I'm like, Okay,
<v Speaker 1>I make sure you stack it the right way, don't
<v Speaker 1>mix them up, you know, don't sandwich anything that you
<v Speaker 1>know belongs on top or on the bottom, et cetera.
<v Speaker 2>So curators are that way everywhere.
<v Speaker 1>Yeah, No, it's it's excellent. It's a high You gotta
<v Speaker 1>have high standards with this stuff, man, So you you
<v Speaker 1>really yeah, I mean, you encourage people to collect and press,
<v Speaker 1>and then there's certainly an art to it too, which
<v Speaker 1>is I love. I mean, that's what makes going in there, Buria.
<v Speaker 1>There's nothing worse than seeing a collection that just looks
<v Speaker 1>like a pressed salad, you know, or like a like
<v Speaker 1>a bunch of leaves somebody accidentally sat on, separate them,
<v Speaker 1>you know, and then yeah, Shirley's mounting is excellent as well.
<v Speaker 1>I do want to mention though, I think you know,
<v Speaker 1>for for especially for delineating species, are figuring out what speed.
<v Speaker 1>You know, something's a certain genus, but you don't know
<v Speaker 1>what species it is. That especially is where the herbarium
<v Speaker 1>comes in to help. If you know you're new to
<v Speaker 1>something and you want to get familiar with, you know,
<v Speaker 1>like Onathra a. There's how many species of onathra used
<v Speaker 1>you know some of them used to be? How many
<v Speaker 1>species of Anatha in West Texas And you're you're you're
<v Speaker 1>having trouble looking at the key whatever. Come to the
<v Speaker 1>herbarium and and look at what's what.
<v Speaker 2>So when we're monographing general for example, if we started there,
<v Speaker 2>what we do is we borrow specimens. We may have
<v Speaker 2>all of them, we may be in the field doing
<v Speaker 2>our own collections and that sort of thing, but we
<v Speaker 2>always borrow specimens from other herbaria, and that's how we
<v Speaker 2>get our populational information. You can't collect everything everywhere. There
<v Speaker 2>have been collectors going on since well since we've occupied
<v Speaker 2>North America, and so these are deposited in Herberia somewhere,
<v Speaker 2>and so we know we know from historical records where
<v Speaker 2>a lot of collections might be located in what Herberia.
<v Speaker 2>So we intentionally borrow specimens, say of Paridley or Tridax
<v Speaker 2>or Inauthra, if that's what we're working on, from other Herberia.
<v Speaker 2>And so that's where we get our information to do
<v Speaker 2>the descriptions and keys and other information that's necessary to
<v Speaker 2>publish monographs of genera. So that goes on for all
<v Speaker 2>kinds of taxonomic studies, whether it's a whether it's a
<v Speaker 2>genus monograph or just doing a regional flora. We need
<v Speaker 2>collections to do that work.
<v Speaker 1>Photographs aren't enough.
<v Speaker 2>Do you need a Photographs are never enough because distinctions
<v Speaker 2>of most species are microscopic recognized vcs. After we know
<v Speaker 2>what they are by gestalt, you know, by morphological characters,
<v Speaker 2>by habit, by their appearance. We learned to recognize them,
<v Speaker 2>but we didn't we learned we know that because of
<v Speaker 2>the taxonomy that was involved previously. Yeah, you know, looking
<v Speaker 2>at microscopic characters.
<v Speaker 1>So a compound scope and a good erbarium are absolute
<v Speaker 1>essentials for.
<v Speaker 2>Botany compound microscopes as well as dissecting microscopes. That's what
<v Speaker 2>I use most is a dissecting microscope right there. Yeah,
<v Speaker 2>so we have several in this herbarium, and we we
<v Speaker 2>have a lot of visitors here and they we have
<v Speaker 2>them available for use for visiting taxonomists or students.
<v Speaker 1>Okay, so is everybody listening obviously, you know, collecting making
<v Speaker 1>herbarium special herbarium vouchers very important. It's critical word. Okay.
<v Speaker 1>So you've also done a lot of plant propagation too.
<v Speaker 1>I mean, sewel Ross was really well well known for
<v Speaker 1>greenhouse native plant sales. You guys were selling madrones for
<v Speaker 1>a while. A lot of this stuff has really odd
<v Speaker 1>germination habits, and you know, some people see as really
<v Speaker 1>hard to grow. When did you get into propagating things?
<v Speaker 1>And I mean this is a whole field we could
<v Speaker 1>talk about you, but yeah, when did you start?
<v Speaker 2>I started growing plants when I first came to soul Ross.
<v Speaker 2>We had a greenhouse here, an indoor greenhouse, believe it
<v Speaker 2>or not, in a new building with nothing in it,
<v Speaker 2>And so I really first started growing plants to use
<v Speaker 2>in botany classes. So we would students would have living
<v Speaker 2>plants in their laboratories to me a lot better than
<v Speaker 2>charts and models. Yeah, so we were using living plants
<v Speaker 2>as much as possible, So I'm talking in the vascular
<v Speaker 2>and non vascular plants. We were growing liverworks and mosses
<v Speaker 2>as well as flowering plants. And then one of the
<v Speaker 2>main techniques and biosystematics monographic studies is growing plants the
<v Speaker 2>use in gardens and greenhouses, especially for artificial hybridizations, because
<v Speaker 2>experimental hybridizations are one way that one can determine relationships
<v Speaker 2>the ease of crossing, for one thing, and then if
<v Speaker 2>one does produce F one hybrids, then the fertility of
<v Speaker 2>F one hybrids is a measure of relationship potentially anyway
<v Speaker 2>between two between species. So attempted to make crosses between
<v Speaker 2>the fifty some odd species of per Italy that I
<v Speaker 2>was studying during those years, and then later on with
<v Speaker 2>another genus, Flavaria. And then during that time, of course,
<v Speaker 2>I was doing gypsum studies too, and trying to grow
<v Speaker 2>gypsum plants and trying to find out what was going
<v Speaker 2>on with that and other native plants because they're nice
<v Speaker 2>in landscaping. And then about that time the landscaping booms
<v Speaker 2>started happening in Texas and so in the you know,
<v Speaker 2>in the the Austin area and Dallas Fort Worth area.
<v Speaker 2>So we accelerated that here at so OSS and I'm
<v Speaker 2>no horticultures, so I just do this by trialing error,
<v Speaker 2>or did it by trialing era. And then we started
<v Speaker 2>started growing all of the trying to grow all of
<v Speaker 2>the woody plants in the trans Vegas just because to
<v Speaker 2>learn how to grow them, for one thing. And then
<v Speaker 2>we we luckily got new greenhouses. President built greenhouses for
<v Speaker 2>us and for this kind of work and for the
<v Speaker 2>taxonomic work we were doing here is the eighties. That
<v Speaker 2>was actually in nineteen eighty that's correct, President Bob Richardson.
<v Speaker 2>He built two state of the art greenhouses for us here.
<v Speaker 2>And I also asked for a native plant demonstration garden.
<v Speaker 2>And it's a small little garden out in front of
<v Speaker 2>the greenhouses now and it just has a regular gorden
<v Speaker 2>soil in it. And because plants in nature look different
<v Speaker 2>or may look different than plants and cultivation, and so
<v Speaker 2>we needed some way to demonstrate to the public that
<v Speaker 2>was just becoming aware of the value of low maintenance plants.
<v Speaker 2>And those with low water requirements in landscaping, and so
<v Speaker 2>I wanted a place where the public could see what
<v Speaker 2>the plants look like in cultivation. And of course they're
<v Speaker 2>quite attractive, our native species, A lot of them do
<v Speaker 2>have large flowers. They're very attractive and grow well under
<v Speaker 2>most any kinds of conditions.
<v Speaker 1>Incredible, Yeah, some incredible stuff, are it?
<v Speaker 2>So we did. We actually grew trees and all kinds,
<v Speaker 2>and I had to remove some trees from a native
<v Speaker 2>plant demonstration garden because they were crowding out everything. I
<v Speaker 2>put them in the wrong place. We had about one
<v Speaker 2>hundred species in there at one time, including some smaller
<v Speaker 2>plants to somemall smaller perennials, and a few annuals that
<v Speaker 2>we could put along a sidewalk because it was sort
<v Speaker 2>of a decoration for their attractive flowers.
<v Speaker 1>I think it's a great context for place too. I mean,
<v Speaker 1>I'm always promoting native plants in whatever region someone's in,
<v Speaker 1>whether it's South Florida or New England, or California or Arizona.
<v Speaker 1>But few places really show the practicality of native plants,
<v Speaker 1>like desert regions, especially West Texas, like I still see
<v Speaker 1>crape myrtles, they're all dead, but crape myrtles being planted,
<v Speaker 1>and you know, and I'm just like, why We've got
<v Speaker 1>such treasures out here. Why are you planting this big
<v Speaker 1>box store garbage. And it's also not going to survive
<v Speaker 1>to it from a completely different climate. The winds here
<v Speaker 1>are insanity. Sometimes the drought here is insanity. You can
<v Speaker 1>feel it on your fingertips and your skin. It's it's crazy.
<v Speaker 1>But these plants are built for them. Some of the
<v Speaker 1>what are some of the structural adaptations you find in
<v Speaker 1>a lot of the plants that are native here to
<v Speaker 1>deal with the climate.
<v Speaker 2>Oh, oh, I'd have to go through a number of things. Well,
<v Speaker 2>narrowing of leaves. Narrow leaves, pubescence, density of pubescence is
<v Speaker 2>one thing.
<v Speaker 1>Reducing leaf area or service.
<v Speaker 2>Reducing of leaf area, yeah, or hairs, evaporation and fewer stata,
<v Speaker 2>positioning of stormata, wax coatings on leaves. Yeah, and on candaliah.
<v Speaker 2>You mentioned candalia a while back, Yeah, the candiliah wax plant.
<v Speaker 1>Photosynthetic stems, I see that a lot.
<v Speaker 2>Yeah, photosthetic stems exactly, root systems, the kinds of root systems,
<v Speaker 2>the depth of root systems and spreading root systems as
<v Speaker 2>in most cacta those kinds of things.
<v Speaker 1>Yeah, because most cacti have roots. I mean some may
<v Speaker 1>form a taproot, but then they'll form roots that really
<v Speaker 1>go out, go laterally to collect rain that may not
<v Speaker 1>always pinet.
<v Speaker 2>Usually shallow roots and spreading fibrous roots. That's correct.
<v Speaker 1>Did you see I mean back then was there? I mean,
<v Speaker 1>have you seen more of an interest than native plants?
<v Speaker 1>Have you seen it growing out here?
<v Speaker 2>It's growing. Yes. The first entries came with people that
<v Speaker 2>moved to the suburbs and maybe in one of the
<v Speaker 2>first developed areas from a ranch west of Alpine. Those
<v Speaker 2>people were interested in native plants and they came in
<v Speaker 2>shopped for them from us. And then the the population
<v Speaker 2>was because this is what people are familiar with. That's
<v Speaker 2>why they grow plants they're familiar with and that they
<v Speaker 2>knew from wherever they came from, and the ones that
<v Speaker 2>are sold in stores and really available. But that's grown
<v Speaker 2>tremendously in this area. There's a Native Flant chapter here
<v Speaker 2>and that sort of thing, and we did it's also
<v Speaker 2>establish a native flant propagation program, an official native flant
<v Speaker 2>propagation program and association with biology. And that's been going
<v Speaker 2>on since the late nineteen seventies here and it's still
<v Speaker 2>going on at this school.
<v Speaker 1>Yeah, I will, you know, I'll be walking downtown in
<v Speaker 1>downtown Alpine and I'll see there's a couple of spots
<v Speaker 1>where there's madrones in people's yards, you know, and like
<v Speaker 1>the right microclimate that especially, I mean, people love that
<v Speaker 1>that tree. It's got beautiful bark, it's related to blueberries.
<v Speaker 1>It can be really hard to grow. It needs special
<v Speaker 1>Michael Rise, it needs to have it at some point
<v Speaker 1>then it's life encounter. But you really nailed down how
<v Speaker 1>to do that, how to grow these from seed from
<v Speaker 1>the little berries. There's two beautiful trees and the native
<v Speaker 1>plant area behind the school and all the ones in
<v Speaker 1>town I presume came from seol Ross. How did you
<v Speaker 1>figure out how to get those things going? And what's
<v Speaker 1>the method?
<v Speaker 2>Trial and error? Again? Well, I did a lot of
<v Speaker 2>things in connection with madrones. For one thing, I collected
<v Speaker 2>fruits from all kinds of places, from the Guadaloupe Mountains
<v Speaker 2>through the Davis Mountains and the Cheezos Mountains and wherever
<v Speaker 2>I could find them. Because of different ecotypes that we
<v Speaker 2>know about different adaptations to drier conditions. Did the same
<v Speaker 2>thing with pines and other kinds of plants, but with
<v Speaker 2>the my drones we're talking about now, I also started
<v Speaker 2>growing them different ways, collecting the seeds or obtaining the
<v Speaker 2>seeds from the fruits, from planting seeds, and different kinds
<v Speaker 2>of media, different kinds of conditions, just to see what
<v Speaker 2>worked the best. And I too thought they needed some
<v Speaker 2>kind of special soil conditions at the time that my seed.
<v Speaker 2>Of course the microflora in the soil, and they obviously do,
<v Speaker 2>but they don't need that they get started. But I
<v Speaker 2>grew them in mulch that I collected from underneath madrones,
<v Speaker 2>and soil collected from underneath madrones, and that sort of thing,
<v Speaker 2>and ultimately I found out it makes no difference at
<v Speaker 2>least in our greenhouses. In my experience. The key thing
<v Speaker 2>is to there are several key things and growing madrones.
<v Speaker 2>One of them is to make sure that you have
<v Speaker 2>viable seeds in the first place, because certain conditions and
<v Speaker 2>you may think that the berries that are produced have
<v Speaker 2>viable seeds because they're berries, but not always. That led
<v Speaker 2>to myth that still persists today that madrones produce low
<v Speaker 2>viable seeds, you know, low viability, and my experience, if
<v Speaker 2>they are pollinated correctly and the conditions are correct, they
<v Speaker 2>are almost one hundred percent viable all the seeds. So
<v Speaker 2>I've done that over and over again, you know, planning
<v Speaker 2>a certain number of seeds to see how many germinate,
<v Speaker 2>and one hundred percent. It happens many, many times. So
<v Speaker 2>I separate the seeds by using my wife and her blender.
<v Speaker 2>For large numbers of seeds. Anyway, so we put a
<v Speaker 2>pretty good batch of fruits and blend them and break
<v Speaker 2>up the fruits and then put them in a paper
<v Speaker 2>bag and let them dry out and crack them up
<v Speaker 2>and shuffle them up, and the seeds go to the
<v Speaker 2>bottom of the sack. And so that's if you have
<v Speaker 2>a large number of seeds and you can get the
<v Speaker 2>seeds from there.
<v Speaker 1>You'll take the berries and put them in a blender
<v Speaker 1>and then just but not for very long, no seconds.
<v Speaker 2>Not at very high speed, but not with the idea
<v Speaker 2>of grinding them as fine as possible, but breaking openness
<v Speaker 2>the fruits. Otherwise, one can remove the seeds one at
<v Speaker 2>a time, I suppose, and that's very laborious process.
<v Speaker 1>And the seeds look like kind of like orange slices.
<v Speaker 2>Tiny little orange slices exactly. Rugos are wrinkled orange slices.
<v Speaker 2>Under exacting microscope, one can easily discern viable seeds or
<v Speaker 2>filled seeds anyway, those that have into sperm. So I
<v Speaker 2>always also do that now. I mean, if I'm growing
<v Speaker 2>them today, I take the time to look under a
<v Speaker 2>microscope and separate seeds. It's still a time consuming process,
<v Speaker 2>but it's you can plant the number of seeds you
<v Speaker 2>want in the container that you choose to plant them in.
<v Speaker 2>And then today we've evolved with containers for growing the seeds.
<v Speaker 2>There were some containers that evidently were invented in the
<v Speaker 2>Northwest for growing pines for reforestation, the long tubes, and
<v Speaker 2>those are the tubes, right, they call containers. They were
<v Speaker 2>called that anyway, and I guess they sell our call containers.
<v Speaker 2>So we started ordering those and there I planted them
<v Speaker 2>in seven inch containers and then discovered that that wasn't
<v Speaker 2>a good size for them, because I'd like to move
<v Speaker 2>them up to one gallon plots after they get established
<v Speaker 2>and after they first developed, and in seven inch containers
<v Speaker 2>the roots are too long and you can j root
<v Speaker 2>plants easily in a gallon plot. That means curving the
<v Speaker 2>roots at the bottom of the pot. Yeah, messes up
<v Speaker 2>there oxens in the direction of growing roots. So anyway,
<v Speaker 2>we use a short containers these days we call stubbies.
<v Speaker 2>There are about five or six inches I forget the
<v Speaker 2>exact length of them. Stubby, the stubby containers the yellow
<v Speaker 2>in color, and we can put them in racks anyway,
<v Speaker 2>growing them in those Why just use ordinary potting medium
<v Speaker 2>that has fertilizer in it. And if there's no fertilizer,
<v Speaker 2>I add Osmo coat after that came along. It's the
<v Speaker 2>time release fertilizer. Watering plants and pots ultimately ultimately leeches fertilizers,
<v Speaker 2>so they need to be fertilized, and the more you
<v Speaker 2>water them, the more they need to be fertilized. But
<v Speaker 2>you can overfertilize plants, and we don't do that with madrones,
<v Speaker 2>and time release fertilizers like Osma coat prevents a lot
<v Speaker 2>of leeching. You know, you don't have to water, you
<v Speaker 2>don't have fertilized you don't have to use a liquid
<v Speaker 2>fertilizer very often. Anyway, the key to growing madrones is
<v Speaker 2>controlling the water in the plotting medium. And that's what
<v Speaker 2>I've found. They tend to get fungal infections since they
<v Speaker 2>have no root hairs. The water has to be just
<v Speaker 2>right for these madrone seedlings to develop all the time.
<v Speaker 1>So there's a narrow window.
<v Speaker 2>You're working with, narrow window. And I use potting medium
<v Speaker 2>without any kinds of heavy material in its. You know,
<v Speaker 2>this is a well draining potting medium. And one can
<v Speaker 2>tell how much water is in a container by lifting
<v Speaker 2>the container. And that's just what I do. Anyway, you
<v Speaker 2>can feel it. So I water when they're dry, not
<v Speaker 2>too dry, I mean they don't let them sip dry.
<v Speaker 2>But as soon as they dry out, I water them
<v Speaker 2>thoroughly or water runs out the bottom, and don't water
<v Speaker 2>them again until they dry out again.
<v Speaker 1>So just basically just see a water when they're.
<v Speaker 3>Dry, exactly.
<v Speaker 2>And it's the way it was to take care of
<v Speaker 2>plants anyway.
<v Speaker 1>But some people like to grow a bunch of stuff
<v Speaker 1>in the same pod, germinate the seeds in the same
<v Speaker 1>pot and separate them later. You can't do that with
<v Speaker 1>madrones obviously.
<v Speaker 2>Right well you can, yes, one can, but better be
<v Speaker 2>careful because their roots go to the bottom. Yeah, if
<v Speaker 2>it's a shallow container, and then the roots go along
<v Speaker 2>the bottom and you can't get the whole root system.
<v Speaker 1>When you're disturbing roots though, if their roots are all intertwined,
<v Speaker 1>I mean, how do you avoid that?
<v Speaker 2>Well, it's hard, you can. You can't avoid it if
<v Speaker 2>you're growing them together. And what the result is you
<v Speaker 2>lose a lot of the plants that you transplant from
<v Speaker 2>that situation. I've never liked growing plants together in flats
<v Speaker 2>of any kind because of that. I started out doing
<v Speaker 2>that frankly. I grew Arizona cypress that way. Yeah, and
<v Speaker 2>then I would weightily got farewell established and separate.
<v Speaker 1>Them and then just keep them in shade for two
<v Speaker 1>or three weeks till their roots can grow.
<v Speaker 2>Yeah. Well, they don't have to be in shade. They
<v Speaker 2>have to have light, yeah, not to bright light, and
<v Speaker 2>not light, not west light, not south or west light,
<v Speaker 2>east east. I found that east light is a bit
<v Speaker 2>in the greenhouse. I put the racks of the drones
<v Speaker 2>in east windows.
<v Speaker 1>Morning sun, morning sun, getting bright light when it's not
<v Speaker 1>very when it isn't heated up yet.
<v Speaker 2>And they get light all day long, but it's they
<v Speaker 2>don't get too hot.
<v Speaker 1>I think, yeah, So I think with this species especially,
<v Speaker 1>it makes sense to just try to sell them individually
<v Speaker 1>in individual pots in those tubes, and then just water
<v Speaker 1>them whenever they try out.
<v Speaker 2>Right, I use four or five or six seeds for kubby,
<v Speaker 2>I mean stubby myself, because I frankly like the multi
<v Speaker 2>stem madrones.
<v Speaker 1>Yeah, and they can grow like that, they can.
<v Speaker 2>Grow like that. They'll be fine, They'll be fine. And
<v Speaker 2>all seedlings don't survive anyway, It's just a thing about
<v Speaker 2>growing plants. Everything doesn't always survive, but.
<v Speaker 1>This species certainly is. I mean, madrones certainly are more
<v Speaker 1>prone to fungal infection when they're young they are most
<v Speaker 1>other plants. And it's you think that's mostly just because
<v Speaker 1>of the lack of root hairs.
<v Speaker 2>Or well, it's from the development. One must use sterile
<v Speaker 2>potting medium. These fungi are developing potting medium from and
<v Speaker 2>spores that come in are spores that are already there.
<v Speaker 2>And so we start with sterol potting medium. It's supposed
<v Speaker 2>to be stero and it's in a sack, but it
<v Speaker 2>may not be. And of course one can heat it
<v Speaker 2>if one wants to make sure they're sterilized. But I
<v Speaker 2>don't do that. I think sterol potting medium and grow
<v Speaker 2>them that way. I have used liquid fungicide before. I
<v Speaker 2>don't like to do that. And the last madrones I grew,
<v Speaker 2>I didn't use any fungicide. It's just stero potting medium.
<v Speaker 1>The soil is just I mean, it's just like a
<v Speaker 1>peat based.
<v Speaker 2>It's peat based, but it has other ingredients in it.
<v Speaker 2>It's it's a commercial mix. I just buy commercial mixed
<v Speaker 2>potting medium as long as it's well draining.
<v Speaker 1>Yeah, I've never been I've never sterilized any soil.
<v Speaker 2>I don't really have to do that now.
<v Speaker 1>I do wonder about though, what I did. What I
<v Speaker 1>have done is some of those I mean, I'm skeptical
<v Speaker 1>of some of those Michael rhizol mixes. You can purchase
<v Speaker 1>all thing. Some might be snake oil, who knows what
<v Speaker 1>they're what their process is forgetting it. But some the
<v Speaker 1>ones that are more reputable, I might get and take,
<v Speaker 1>you know, mix it up and then take like a
<v Speaker 1>And I've done this with pines too, even though it's
<v Speaker 1>probably not necessary. Maybe it's a placebo for me, who knows,
<v Speaker 1>But I'll take a meat uh injector you know, you
<v Speaker 1>can get on Amazon for like injecting meat. It was
<v Speaker 1>like a giant syringe and up. But the it's got
<v Speaker 1>a large gauge tube's needle and then I'll just fill
<v Speaker 1>it with Michael rhiselin and inject the soil. You know,
<v Speaker 1>and who knows. I haven't done any tests obviously, that.
<v Speaker 2>Sounds like a yeah.
<v Speaker 1>I mean the spores are good, yeah, because you know.
<v Speaker 1>I also I remember I was in the Davis Mountains
<v Speaker 1>with Adam Black a few months ago and I was
<v Speaker 1>doing the same thing you would talk about, trying to
<v Speaker 1>collect the duff that you could see my celium on already.
<v Speaker 1>I don't know if it was just the saprotrophic fungi
<v Speaker 1>or my or Micae rhizol or what, but I was like,
<v Speaker 1>what the hell it went? You know, why not? But
<v Speaker 1>I was so desperate. But the deer. I had one
<v Speaker 1>that I got from Sewel Raw and I was I
<v Speaker 1>put it in the ground. It got to two and
<v Speaker 1>a half feet tall. The minute I took the fence off,
<v Speaker 1>the deer came nibbled it down. And then Dan Hostage
<v Speaker 1>was telling me they don't come back after that. If
<v Speaker 1>they're that young and they get they lose all their leaves.
<v Speaker 1>They try to re sprout, and then the new leaves
<v Speaker 1>just rot, which was really Again, I don't know why.
<v Speaker 1>It's some discrepancy between the roots and the shoots. I
<v Speaker 1>guess I don't know, but I was angry. Angry.
<v Speaker 2>I have found that half in this area. One must
<v Speaker 2>protect madrones from herbivores until they get above the brows line.
<v Speaker 2>That is, if if herbivores can get to madrone, that's
<v Speaker 2>ain't number one good?
<v Speaker 3>Yeah, yeah, So I have them drone at home.
<v Speaker 2>I've grown several on my property, and I have them
<v Speaker 2>in wire cages until they get to above the.
<v Speaker 1>What do what? The deer will avoid things like salvia
<v Speaker 1>and obviously anything that's very pungent. Probably a lot of
<v Speaker 1>composites they'll avoid too.
<v Speaker 2>If it's they're avoid certain kinds of plants, but not
<v Speaker 2>very many. They try them out. If they don't mind
<v Speaker 2>having stems broken off your salvis, they don't mind breaking
<v Speaker 2>stems off my salvia or mary regulars, regulars at home
<v Speaker 2>try them out and spit them out.
<v Speaker 1>Have they always been like this in town where there's
<v Speaker 1>just these massive deer herds?
<v Speaker 2>Oh, since I've been in Alpine and they've they come
<v Speaker 2>and go from Hankock Hill.
<v Speaker 1>Yeah, it depends how what the rain is like.
<v Speaker 2>It depends on where they have something to eat. It's
<v Speaker 2>like deer jumping on the highway rights of way and
<v Speaker 2>there's more water running off the highway and so they
<v Speaker 2>jump in to get some food there when it's when
<v Speaker 2>it's sparse in the pastures. So they've been coming into town.
<v Speaker 2>When I lived in town, I had three madrone trees
<v Speaker 2>and my yard and some pines and some oaks, and
<v Speaker 2>even if giants of quaria. As a matter of fact,
<v Speaker 2>Oh really, two of them growing in my yard.
<v Speaker 1>Yeah did they last?
<v Speaker 2>Somebody cut them down after I moved. Yeah, they were
<v Speaker 2>there for years. They were tall.
<v Speaker 1>That's crazy. Yeah, I forgot that.
<v Speaker 2>Somebody brought me some seeds from California, so I had
<v Speaker 2>to grow them.
<v Speaker 1>Yeah, that would do well out here. Those things move
<v Speaker 1>fast when they get there. Oh yeah, they've got water.
<v Speaker 2>A lot of plants grow faster than people think when
<v Speaker 2>they get water. That's this desert plant. Desert plants love water.
<v Speaker 2>They grow better when they get.
<v Speaker 1>And they always look so much better and native like
<v Speaker 1>in a garden. That's the thing with native that's why
<v Speaker 1>native plant currents are so important because you can create
<v Speaker 1>such a great seed bank of things that you know
<v Speaker 1>might not be doing well due to drought in the
<v Speaker 1>region or you know whatever human impacts. But anyway, well,
<v Speaker 1>I want to talk about gypsu fhiles too, because I
<v Speaker 1>think that phenomenon is really interesting, especially to people who
<v Speaker 1>may not know what that is. So gypsum is a
<v Speaker 1>sedimentary marine rock. It's much more water soluble than limestone,
<v Speaker 1>and it's you know, a remnant of you know, shallow
<v Speaker 1>water estuaries, briny area, saltwater lagoons, whatever that were existing
<v Speaker 1>you know, a long time ago, sixties seventy million years,
<v Speaker 1>and it's throughout the Chyuai Want desert. You often get
<v Speaker 1>gypsum with limestone. There's a lot of gypsum in West Texas,
<v Speaker 1>and it's like serpentine in that it's a geologic substrate
<v Speaker 1>that kind of induces speciation, like it selects for plants,
<v Speaker 1>and so you get new plant species evolving that are
<v Speaker 1>restricted to gypsum. When did you start getting into that
<v Speaker 1>and what have you documented?
<v Speaker 2>Well, that goes back to until in the late nineteen sixties.
<v Speaker 2>Actually I knew about gypsum plants before that, but point
<v Speaker 2>we had we had a thriving Department of Biology and
<v Speaker 2>lots of graduate students, and finding thesis studies for graduate students,
<v Speaker 2>you know, projects, is an ongoing thing. And so at
<v Speaker 2>one point I asked my professor Turner if he had
<v Speaker 2>any good suggestions about possible thesis topics for graduate students.
<v Speaker 2>And so he gave several suggestions about kinds of plants
<v Speaker 2>and then mentioned gypsum plants. I said, well, I'll look
<v Speaker 2>into that further. And I already knew about some early
<v Speaker 2>studies by Ivan M. Johnston in Mexico. He was a
<v Speaker 2>borad expert and he was doing some some of his
<v Speaker 2>work and in the Boltsontimpai and from Drongo into uh
<v Speaker 2>Suawan Koela in that area, and so he collected some
<v Speaker 2>gypsum plants and wrote a paper about it. And then
<v Speaker 2>another researcher that was in nineteen forty one, by the way,
<v Speaker 2>and about nineteen fifty one another person sort of took
<v Speaker 2>up what Ivan M. Johnson started in Oklahoma and south
<v Speaker 2>southeastern New Mexico and in a little bit in Transpacos, Texas.
<v Speaker 2>That's a ut waterfall. He was at University of Oklahoma
<v Speaker 2>and Oklahoma stayed at different times, so he published a
<v Speaker 2>paper in nineteen fifty one, so I had that to
<v Speaker 2>go by, But and I knew where a lot of
<v Speaker 2>the gypsum deposits were, but not all of them. So anyway,
<v Speaker 2>we started looking around for them here and then we
<v Speaker 2>started visiting the one at the Castian gypsum deposit Permia's
<v Speaker 2>permian Age south of the Guadaloupe Mountains in Culberson County,
<v Speaker 2>southeastern New Mexico. And then we started finding other gypsum
<v Speaker 2>deposits in other areas in Culberson County and Husabeth County
<v Speaker 2>and then ultimately farther south in the Transpacos and then
<v Speaker 2>Mexico all the way to San Luis, pot to see,
<v Speaker 2>and there are great gypsum deposits there. As you mentioned,
<v Speaker 2>Quatro Cienegus is a famous place and with white gypsum
<v Speaker 2>dunes like those in the southern New Mexico, and there
<v Speaker 2>are white gypsum dunes in the Transpacus as well west
<v Speaker 2>of the Guadalupe Mountains and where there are gypsum endemics
<v Speaker 2>by the way, So anyway, I started visiting these areas
<v Speaker 2>and encouraging students to go with me. We even developed
<v Speaker 2>a class called field taxonomy and field botany here, and
<v Speaker 2>so I took students to these areas and we did
<v Speaker 2>sort of class studies of using the situation the endemism
<v Speaker 2>and gypsum habitats. One can go from say the Castian
<v Speaker 2>deposits twenty thirty miles away over the Delaware Mountains and
<v Speaker 2>north of Van Horn and find different species that have
<v Speaker 2>been selected for on that gypsum deposit I go to
<v Speaker 2>another place, say in Mexico, twenty miles away, fifty miles away,
<v Speaker 2>one hundred miles away, at different gypsum deposits and on
<v Speaker 2>different different gypsum floras. So we started collecting the plants
<v Speaker 2>on these different gypsum habitats and doing papers about that.
<v Speaker 2>And then I started collaborating with Billy Turner again about that,
<v Speaker 2>and he started doing a lot of gypsum studies in
<v Speaker 2>Mexico as well.
<v Speaker 1>So you guys were probably finding a ton of new species.
<v Speaker 1>I mean this all over the place, high levels of
<v Speaker 1>diversity and endemism. And what's a relatively small geographic area
<v Speaker 1>a few hundred miles right, What were some of the
<v Speaker 1>most exciting ones you found that were just, you know,
<v Speaker 1>really fascinating.
<v Speaker 2>Oh well, there are a number of them. What's coming
<v Speaker 2>to mind right now is something that came to mind
<v Speaker 2>fairly recently when I was doing another project. I remember
<v Speaker 2>four species from one Jurassic gypsum deposit between Ohinaga and
<v Speaker 2>Shuaha City. Yeah, in in Chihuahua, about halfway there, close
<v Speaker 2>to the to a lake there, Lake Lee Lewis leon
<v Speaker 2>Forresa Granero, the dam. Uh. There was a Galordia species there.
<v Speaker 2>There was a prickly poppy, our jeminy species there. There
<v Speaker 2>was a dermatic phillim species there. Sephora used to be Sephorah,
<v Speaker 2>a mountain laurel species. Uh, sort Wellia composite species in
<v Speaker 2>a small area there. All endemics, all endemics there and
<v Speaker 2>the only place they occur on Earth today as far
<v Speaker 2>as we know. Uh, the Dermatophillum gypsophalom occurs there. We
<v Speaker 2>named we named all of them.
<v Speaker 1>Uh.
<v Speaker 2>The Gaylordia were named it Turneri and it actually the
<v Speaker 2>our gemeny is named our Geminy Turnery after Billy's wife
<v Speaker 2>sort Willia.
<v Speaker 1>Is Is there any protection for that area so far
<v Speaker 1>as you know?
<v Speaker 2>No, No, it's not, as far as I know. Gypsum
<v Speaker 2>is mind as you know, for plaster and plasterboard, it's
<v Speaker 2>a commercial product. In cement, it's a commercial product. And
<v Speaker 2>so where we found the the what became it was
<v Speaker 2>for at the time, the demount of film was in
<v Speaker 2>an area that was being mined at the time. I
<v Speaker 2>have no idea if it's still there. Maybe it is
<v Speaker 2>and maybe it isn't. But the Mexican botanists are getting
<v Speaker 2>better and better all the time, and they're really concerned
<v Speaker 2>with conservation, like like we are here great botanist in Mexico,
<v Speaker 2>and and they're doing conservation work all the time, doing
<v Speaker 2>good DNA studies and that, and so they're quite aware
<v Speaker 2>of all these things. Quadras hasn't been very well protected,
<v Speaker 2>but it's that's because there's water there and that's the
<v Speaker 2>problem there, I think. But they're all aware of that
<v Speaker 2>and trying to protect all of those things.
<v Speaker 1>Now there's a what is that weird lofa for that's
<v Speaker 1>freaky I for ci that's around that area, isn't it.
<v Speaker 1>But that's not a gypsum endemic.
<v Speaker 2>I don't know if that I know of anyway. Yeah,
<v Speaker 2>I wasn't much in the Kectie at the time. But
<v Speaker 2>I should have been, but I wasn't. Yeah, you certainly
<v Speaker 2>got yeah, because there's so many different kinds of here.
<v Speaker 1>Yeah. But going back to the gypsum endemics, I mean,
<v Speaker 1>from what I know, there's a gypsum endemic a gave
<v Speaker 1>down in Wahaka. There's I mean this, yeah, this is
<v Speaker 1>these exposures go far north to south, from Albuquerque all
<v Speaker 1>the way down to well Haka. The some of the
<v Speaker 1>traits I've noticed, especially in the more arid areas. That's
<v Speaker 1>the other thing is, Yeah, gypsum is normally it's almost
<v Speaker 1>always in arid regions where because otherwise it would just
<v Speaker 1>be washed away. But the traits that you find in
<v Speaker 1>a lot of these they're almost white. They're like a
<v Speaker 1>much more pubescent dwarfed a little bit. I imagine it's
<v Speaker 1>probably pretty stressful growing on some of these deposits, not
<v Speaker 1>a lot of nutrients. What do you think it is
<v Speaker 1>that makes growing on gypsum so stressful and causes these
<v Speaker 1>new species to evolve that require new adaptations.
<v Speaker 2>Well that there are gypsum deposits all over the world,
<v Speaker 2>as you know, and there are a lot of them
<v Speaker 2>in this area that have been exposed by erosion, and
<v Speaker 2>I guess they're still eroding a little bit. But there
<v Speaker 2>have been quite a few studies since my time anyway,
<v Speaker 2>of people looking into those questions you ask, and I
<v Speaker 2>don't think they're completely answered yet. In my experience, plants
<v Speaker 2>grow there because of the structure, and they're selected not
<v Speaker 2>because of the calcium sulfate that's in gypsum, but because
<v Speaker 2>of the structure of the gypsum habitats. That seems to
<v Speaker 2>be a restricting factor. There could be minerals as well,
<v Speaker 2>different kinds of mineral situations. That's a very good question
<v Speaker 2>why they're restricted there. So they're exposed at different times,
<v Speaker 2>and theoretically caedes are dispersed by some mechanism for related species,
<v Speaker 2>so they've managed to get to another exposed gypsum habitat
<v Speaker 2>where they can grow and other pants are selected against.
<v Speaker 2>And there are plants that grow strictly on gypsum, those
<v Speaker 2>that grow on gypsum and elsewhere. They're called gypsum vags.
<v Speaker 2>Now we call them facultative gypsyphiles in my time. And
<v Speaker 2>then there are those that never grow on gypsum. And
<v Speaker 2>as you've pointed out, the distinction between a gypsum deposit
<v Speaker 2>sometimes is like drawing a line on the floor. It's
<v Speaker 2>very stark, very stark, and so a gypsyphile will be
<v Speaker 2>on one side of the line and non gyps of
<v Speaker 2>else would be on the other side line. I've seen
<v Speaker 2>that often in Culbersom County, for example, where that permium
<v Speaker 2>gypsum is located. The kalia hispoedisima grows on gypsum and
<v Speaker 2>nowhere else in.
<v Speaker 1>My experience, Nama Carnosa too.
<v Speaker 2>Nowma Carnosa exactly. It's another good one there.
<v Speaker 1>And some of these some of these deposits just look nuts.
<v Speaker 1>I mean they look like just bright white. You could
<v Speaker 1>see them from a satellite. Uh, you know, the texture
<v Speaker 1>of concrete, like poorly mixed concrete when it's dry, like
<v Speaker 1>very rough. It's a really interesting phenomenon. I think things
<v Speaker 1>like that, especially when you point that out. The people
<v Speaker 1>who may not be interested in the in bodany initially,
<v Speaker 1>they see that and they're some of them find it
<v Speaker 1>so confounding and cool and fascinating that they you know,
<v Speaker 1>it's that you could see their eyes light up a
<v Speaker 1>little bit. They're like this there. Really, I had no
<v Speaker 1>idea that this kind of phenomenon occurred.
<v Speaker 2>They were gyps gyps and sites were neglected by botanists
<v Speaker 2>in the past, probably because they look like they're practically
<v Speaker 2>devoid of vegetation for most of the year. When it rains,
<v Speaker 2>they light up like most areas do, and then if
<v Speaker 2>a botanist happened by, they were collected, probably, but they
<v Speaker 2>were generally very undercollected. That's why we found lots of
<v Speaker 2>undescribed species there.
<v Speaker 1>I think what you said, most of the annual callists
<v Speaker 1>are gypsophiles, right, that's correct. There's maybe what a few
<v Speaker 1>that grow off of it, but most you find.
<v Speaker 2>Are in deluted gypsum, and there are some that grow
<v Speaker 2>in a kind of a clay e gypsum that actually
<v Speaker 2>we sort of realized was a true gypsophile kind of habitat.
<v Speaker 2>In this area there are gypsies clays and the southern
<v Speaker 2>Big Bend area of Cretaceous age where there were selenite
<v Speaker 2>crystals are quite obvious there, and there are gypsophiles in
<v Speaker 2>the clay, and some of those are any the calls species.
<v Speaker 1>Like like Agua Fria. Would that be a good That's a.
<v Speaker 2>Good example where those gypsies clay occur.
<v Speaker 1>There's a slea down there too.
<v Speaker 2>There's a Stanleia there and they they're sort of a
<v Speaker 2>marginal gypsyphile. Stanley Is it's known for absorbing selenium and
<v Speaker 2>is known as an uranium indicator.
<v Speaker 3>In Utah.
<v Speaker 2>There's such a thing as geological prospecting, and I got
<v Speaker 2>into some of that too because it sort of interests me.
<v Speaker 2>There are certain plants that are indicators of minerals, you
<v Speaker 2>know that that miners are interested in, like gold and
<v Speaker 2>silver and cinnabar and all kinds of other things.
<v Speaker 1>That's wild nickel, Yeah, yeah, nickel, all kinds of things. Yeah.
<v Speaker 1>The that area agm Havardia. Is that a gypsyphile, that
<v Speaker 1>little cushion there.
<v Speaker 2>It's a it's a questionable gypsyphile, but it occurs in gypsum,
<v Speaker 2>but it occurs in the high a diluted gypsum gypsum
<v Speaker 2>habitats as well, but it is restricted by something and
<v Speaker 2>that area, as is the carrier recipes.
<v Speaker 1>Right. God, it's such a that is such a unique
<v Speaker 1>area from Botany too.
<v Speaker 2>It's so it is, and we revisit that all the time.
<v Speaker 2>One of our gypsyphiles was discovered there. It was a gypsyphile.
<v Speaker 2>You know this one too, the pseudo Clappya Watsonia. Yeah,
<v Speaker 2>it was described from a Husbeth County in a ging
<v Speaker 2>gypsyis class and as far as we knew, it was
<v Speaker 2>restricted there until it was found at that Alla Fria
<v Speaker 2>site and one little place there.
<v Speaker 1>It's just that's how big. It's a small population.
<v Speaker 2>It's a very small population there. But we found it
<v Speaker 2>again recently Kelsey Wogan and I did in big the
<v Speaker 2>National Park. So it's it's a as a further reach
<v Speaker 2>than we knew.
<v Speaker 1>Well that there's another you guys found on the population
<v Speaker 1>that one was there.
<v Speaker 2>Yeah, well not just recently the last. Every time we
<v Speaker 2>go somewhere we find something new potentially or find something
<v Speaker 2>interesting anyway.
<v Speaker 1>Yeah, that that spot, the one I'm thinking of, is
<v Speaker 1>really really cool. There's really cool bad land formations, petrified
<v Speaker 1>wood everywhere.
<v Speaker 2>And it needs to be revisited time and time again.
<v Speaker 2>We also found a actually and it's fairly invasive grass species.
<v Speaker 2>It wasn't known for the Transpacus uh in that that
<v Speaker 2>habitat is that one of the drainages. It's a let
<v Speaker 2>me think of the name, it's Andropogona. It'll come to
<v Speaker 2>him in a minute.
<v Speaker 1>Was it from where? What's the origin? Africa?
<v Speaker 2>Well, it's a I'm not sure if its origin, probably,
<v Speaker 2>but it's all over Texas and South Texas. But it's
<v Speaker 2>most it's most closely known distribution prior to this was
<v Speaker 2>in Valverde County. It's not a very large range extension,
<v Speaker 2>but it is with all we knew all the grasses
<v Speaker 2>in the trans Vegas. But it's a large grass too.
<v Speaker 1>It's not a large range extension.
<v Speaker 2>Now what it could be, Well, I doubt if it's
<v Speaker 2>going to occur anywhere else. It must be restricted to
<v Speaker 2>those gypsum sites.
<v Speaker 1>It's the other plan I want to ask you about
<v Speaker 1>to Castilla Stewarty, which used to be what was that
<v Speaker 1>Hollacantha start that's a.
<v Speaker 2>Really Olacantha stewarty it used to be and now it's castilla.
<v Speaker 1>That's a unique one. Is that Would you say that's rare?
<v Speaker 2>I would say it's rare, yes, But it's widespread in
<v Speaker 2>this area. At least it occurs in Shafter and uh,
<v Speaker 2>it occurs at all Freea where you were talking about,
<v Speaker 2>occurs in big Ben National Park, and it probably occurs
<v Speaker 2>at Black Gap. I don't know why I wouldn't, but
<v Speaker 2>I'm not sure it's been found.
<v Speaker 1>There is that a limestone endemic or no?
<v Speaker 2>Well it no, it occurs in mixed deets as well.
<v Speaker 2>The Courson Volcanic Habitat and Big b A National Park.
<v Speaker 1>Those plants that are limestone endemics, like Concilius koposa or
<v Speaker 1>I mean a kind of cactus Warzantalonius has generally thought
<v Speaker 1>as that too. What do you think it is about
<v Speaker 1>limestone that makes those plants restricted to just the chemical differences,
<v Speaker 1>the pH levels I mean, obviously very different from volcanic
<v Speaker 1>But that's a really interesting phenomenon.
<v Speaker 3>It's all.
<v Speaker 2>That's an interesting question about all edaphic endemics. I don't
<v Speaker 2>think we know from Serpentine on through the things that
<v Speaker 2>you've mentioned. Evaculate in a marathon basin and a few
<v Speaker 2>other places.
<v Speaker 3>Oh yeah, that's another cool west Why they're there.
<v Speaker 2>There should be nothing in that Devonian silicious material that
<v Speaker 2>can be absorbed by plants. Maybe there is something, but
<v Speaker 2>it's probably structure. Again, I'm just guessing. Of course, there
<v Speaker 2>are several species of cacti that are in there and
<v Speaker 2>nowhere else.
<v Speaker 1>Let's talk about that and novaculate because that's a those
<v Speaker 1>those exposures are only found in a few areas in
<v Speaker 1>West Texas, I guess. I mean they occur in other
<v Speaker 1>regions too, but in West Texas it's not somewhat limited.
<v Speaker 1>And that's another case of adaphic nimism. How many species
<v Speaker 1>you get that are a daphak endemics you can think
<v Speaker 1>of all.
<v Speaker 2>In evaculate, Yeah, I think about six or seven cactus species.
<v Speaker 2>There's a Peronicia carryoflesi Pera, Nikia Wilkinsonia, I think, And
<v Speaker 2>there are probably others that are not coming to mind
<v Speaker 2>right now, or we may not even know about because
<v Speaker 2>we really haven't botanized and evaculated as thoroughly as it
<v Speaker 2>could be.
<v Speaker 1>It kind of serious. The vidya is that it vitii
<v Speaker 1>and uh Escobaria minima.
<v Speaker 2>Escobaria now Pelisiphora minima unfortunately. Yeah, that and Hesteri. You
<v Speaker 2>mentioned that or did you? No?
<v Speaker 1>I didn't, I didn't.
<v Speaker 2>Hester I supposedly was an endemic there, but now we
<v Speaker 2>found it on another place on the on volcanic soil too,
<v Speaker 2>just over the hills.
<v Speaker 1>Yeah, I think I've seen it. I've seen that that
<v Speaker 1>spot is that off Longfellow.
<v Speaker 2>Maybe, Well, no, it comes over the hill on ignoist
<v Speaker 2>material south of Alpine, about ten or twelve miles curs
<v Speaker 2>on my property there as a matter of fact.
<v Speaker 1>Oh wow, there's a yeah, there's there's It seems like
<v Speaker 1>there's a lot to be discovered out here. It just
<v Speaker 1>requires access to the land. That's great, making friends with
<v Speaker 1>the landowner or ownership changes, and maybe someone's you know,
<v Speaker 1>more amenable to letting botanis on to look at things.
<v Speaker 1>Do you what do you think there's I noticed that
<v Speaker 1>there was from what I hear, there was a certain
<v Speaker 1>decade at which fear of letting people on your land
<v Speaker 1>became more prominent. Was that after Endangered Species Act? Or
<v Speaker 1>when did the flavor kind of change?
<v Speaker 2>And my experience it was after the Endangered Species Act?
<v Speaker 2>And and of course the venters I think had some
<v Speaker 2>reservations about having rare things discovered because they might be
<v Speaker 2>controlled by the federal government. That's the sort of the
<v Speaker 2>word I get.
<v Speaker 1>Anyway, But that's not a reality.
<v Speaker 2>At least endangered species don't jump fences, and so the
<v Speaker 2>rules are different, the federal and the state rules.
<v Speaker 1>The dangered plant species versus.
<v Speaker 2>And animals are different from plants, and so there is
<v Speaker 2>no problem in dangered species, but there's just the same
<v Speaker 2>I think there's a fear of that.
<v Speaker 1>The fear remains that, yeah, a lot more guarded. So
<v Speaker 1>you saw people becoming a lot more guarded about access
<v Speaker 1>after that, whereas before because a lot of these private
<v Speaker 1>parcels are huge and people may not even live on
<v Speaker 1>them or anywhere near them, and so you know, yeah,
<v Speaker 1>prior to that, I could them being like, sure, go out,
<v Speaker 1>you know, just after establishing a certain sense of trust.
<v Speaker 1>But then I guess what was in dangered species like
<v Speaker 1>early seventies Nixon.
<v Speaker 2>I think nineteen seventy three if I remember correctly.
<v Speaker 1>Yeah, now, but you've probably seen it's probably been a
<v Speaker 1>lot harder to gain access to some of these places.
<v Speaker 2>Now, Yeah, early on too, I started trying to locate
<v Speaker 2>all of those supposedly rare species in the Transpacus. After
<v Speaker 2>I became provincial enough to have to concentrate on this area.
<v Speaker 2>Didn't have the money to go all over from grant support.
<v Speaker 2>So one of the things I like to do is
<v Speaker 2>try to find out the distributions of all and the
<v Speaker 2>localities of all of the supposedly rare or nearly rare species.
<v Speaker 2>So it was fun looking in the field for those,
<v Speaker 2>but you still couldn't go everywhere. I could do a
<v Speaker 2>lot of work in BigMan National Park because you could
<v Speaker 2>get permits there from the government, and in state parks
<v Speaker 2>we could go there.
<v Speaker 1>What are what were what are some species that would
<v Speaker 1>be good, you know, to put on a bucket list
<v Speaker 1>if anyone's ever able to get access that, you know,
<v Speaker 1>you would be curious about, like I wonder if that
<v Speaker 1>population is still extent, or if it's how it's doing whatever.
<v Speaker 2>Well, I said, if you knew where they were, that's
<v Speaker 2>one of the main problems. So I don't know what
<v Speaker 2>to say to answer that.
<v Speaker 1>So a lot of these the distribution is just not
<v Speaker 1>fully Yeah, the.
<v Speaker 2>Distribution isn't known and just as just as taxonomy isn't
<v Speaker 2>well known in some areas, because we know that distributions
<v Speaker 2>of some species are very restricted. M like the one
<v Speaker 2>that was recently discovered, right, yeah, well we'll get tourculate
<v Speaker 2>by radiator.
<v Speaker 1>But it sounds like there's big there's big blank parcels
<v Speaker 1>on the map for some some of these distributions. There
<v Speaker 1>very well could be range expansions.
<v Speaker 2>That's definitely true.
<v Speaker 1>Other unknown populations, that's just there's no access, there's no
<v Speaker 1>way of knowing they're there, and.
<v Speaker 2>We've we've documented that in some cases by but access
<v Speaker 2>we didn't have before. For example, a few ranches. There
<v Speaker 2>is a ranching in the Big Band area south of here,
<v Speaker 2>south of Alpine, where there is there is some access
<v Speaker 2>now from the from the ranching conglomerate, and we've been
<v Speaker 2>able to do some botanizing there fairly recently.
<v Speaker 1>There was another species of composite discovered a few years ago,
<v Speaker 1>a population uh down there right, what was that was it?
<v Speaker 2>It was actually no from Mexico before that. It's a
<v Speaker 2>Mexican species on the Kueva Nueva Leoned Khela border in
<v Speaker 2>that area. Highly restricted species, and it was collected in
<v Speaker 2>nineteen twenty nine by a ranch foreman on that ranch
<v Speaker 2>who collected plants. We have thousands of his collections in
<v Speaker 2>this heerberium. It was a ranch foreman and twenty eight
<v Speaker 2>in the twenties and early thirties collected fossils and all that.
<v Speaker 2>He was interested in plants, so he made two plant
<v Speaker 2>collections of this platy limit Palmerum. They're in this herberium,
<v Speaker 2>but we didn't know what they were never heard of
<v Speaker 2>plaidy Limo Palmer myself. So when Billy Turner was working
<v Speaker 2>in the Herberium he came to those, he didn't know
<v Speaker 2>what it was either, so he took them to Austin,
<v Speaker 2>where they have a wide collection of Latin American plants,
<v Speaker 2>especially Mexican species, and he found out what it was.
<v Speaker 2>And of course then we knew where it exists here,
<v Speaker 2>but we didn't have access, so we all looked for
<v Speaker 2>it along the road for a number of years. This
<v Speaker 2>is one of the stories I could.
<v Speaker 3>Tell, never found it.
<v Speaker 2>Every time I went south, we Shirley and I we
<v Speaker 2>would jump out and I would walk a distance here
<v Speaker 2>there I hadn't walked before looking walk on the road side,
<v Speaker 2>walking the roadside because exactly that's where we do a
<v Speaker 2>lot of botanizing, because the same plans that occur across
<v Speaker 2>the fencer on the road side usually so so that's
<v Speaker 2>where we do a lot of botanizing. And the water
<v Speaker 2>is better there anyway, because it runs all the pavement.
<v Speaker 2>So I would look there forever and ever never found it.
<v Speaker 2>So one day, this is part of the story. The
<v Speaker 2>Range Animal Science Department had access to this this this
<v Speaker 2>ranch doing some range vegetation and a range range work
<v Speaker 2>there and other kinds of experimentals things they were doing.
<v Speaker 2>And a graduates didn't walked in here, and what happened
<v Speaker 2>to know who he was because we'd met before and
<v Speaker 2>he was interested in plants and he was doing a
<v Speaker 2>transact for this person that was doing range research there.
<v Speaker 2>So in a little paper towel, wet papertail, he had
<v Speaker 2>this plant and he opened it up and I've recognized
<v Speaker 2>it immediately, his platy limba palm rod.
<v Speaker 1>I've been the one. It was the one you've been
<v Speaker 1>looking for exactly eighty years.
<v Speaker 2>God, it was unknown eighty years. So that's an interesting
<v Speaker 2>little story. So then he started looking around and we
<v Speaker 2>were luckily invited to join him on this ranch, and
<v Speaker 2>we looked on throughout a lot of the area anyway,
<v Speaker 2>and found that it's quite abundant there, but it's highly
<v Speaker 2>restricted to one soil type on that ranch. So it's
<v Speaker 2>another edaphic endemic. What is it to limestone, Well, it's
<v Speaker 2>it's not it's not rocky, but it's a it's a
<v Speaker 2>elementary deposit of a certain kind. And I don't know
<v Speaker 2>that much about soils. It has a name you know,
<v Speaker 2>the soil scientists have a name for it, and that's
<v Speaker 2>I think it's posted on I'm just on a poster
<v Speaker 2>oute in the hall. There was Chris Jackson who made
<v Speaker 2>you rediscovered that a graduate student here.
<v Speaker 1>At so was he a botanist or just arranged signce
<v Speaker 1>he was.
<v Speaker 2>Doing a range science experiment. They wound up doing his
<v Speaker 2>thesis concerning that platy Limo Palmer, though his chromosome number
<v Speaker 2>was unknown and the whole kinds of thing. Actually, we
<v Speaker 2>knew the chromosome number before we've re located it here
<v Speaker 2>because new Mexico botanist Rich Spelenberg came across it in
<v Speaker 2>Mexico and collected buds in Mexico and brought them to me,
<v Speaker 2>left him on the table right there on the table
<v Speaker 2>because he had to go back to Los Crusis. So
<v Speaker 2>I got a count from his buds, and so we
<v Speaker 2>already knew the chromosome number from Mexico. But it's the
<v Speaker 2>same thing here.
<v Speaker 1>Did they do you guys publish a paper on this?
<v Speaker 2>Well it's published, yeah, yeah, and a new new.
<v Speaker 1>Populations that are rediscovered yep.
<v Speaker 2>That's Paturner published that, and because he knew what it
<v Speaker 2>was in the year two thousand and then the chromosome
<v Speaker 2>number is published in a different paper.
<v Speaker 1>Wow.
<v Speaker 2>And then and so information about that. Chris Jackson, as
<v Speaker 2>far as I know, hasn't published his thesis.
<v Speaker 1>Wow, that's wild though, eighty eight years lost.
<v Speaker 2>It's there are many things yet to be found.
<v Speaker 1>Did you guys try growing that one from seed?
<v Speaker 2>Yeah? It grows from seed. It actually has a very
<v Speaker 2>long route and it goes very deep in alluvial soil.
<v Speaker 1>Okay, so that's that might be one. It's restricted to that.
<v Speaker 2>Yeah. Very soon after that, I found it roadside too.
<v Speaker 1>Yeah, I trying to find there. I found Paganam Mexicanum nearby.
<v Speaker 2>Paganam Mexican Kingdom locale. It's across the fence from there, Okay,
<v Speaker 2>but it's farther up the road. Well, it's right there too,
<v Speaker 2>and I'll give you further directions where you can find
<v Speaker 2>a couple of plants.
<v Speaker 1>It's further Mexican.
<v Speaker 2>Well, it's the better population that we found ultimately at
<v Speaker 2>roadside was further north from the Paganum locality. But we
<v Speaker 2>also finally located it thanks to Kelsey's good eyes. Close
<v Speaker 2>to that Piganem Mexicanum locality right adjacent to it. In fact, Wow,
<v Speaker 2>I'll give you some directions.
<v Speaker 1>Okay, yeah, I'll be kidding.
<v Speaker 2>But it's the rain first. Yeah, hopefully it didn't even
<v Speaker 2>show up last year.
<v Speaker 1>It's been Is this the worst? Is this the driest
<v Speaker 1>year you've seen since you've been there? One of them?
<v Speaker 1>Or what?
<v Speaker 2>Everyone seems drier than the other. But right now I
<v Speaker 2>would say, yes, you know there are there are desert
<v Speaker 2>plants that are dying all over.
<v Speaker 1>Yeah, okay, So I think it's fitting for the end
<v Speaker 1>of the conversation here to talk about this new composite
<v Speaker 1>species that was discovered last year. I mean it's only
<v Speaker 1>been known to science for a year oviculate by radiata,
<v Speaker 1>which you actually have already grown from seed. You successfully
<v Speaker 1>grew it. I think that's interesting too. What do you yeah,
<v Speaker 1>what would I mean, You've been here for so long
<v Speaker 1>you to still think that there's new species out there
<v Speaker 1>to be described, especially in a national park which you
<v Speaker 1>would assume has already been thoroughly surveyed. What did you
<v Speaker 1>think of that?
<v Speaker 3>Well?
<v Speaker 2>I thought it was remarkable, predicted, predictable that there would
<v Speaker 2>be new things discovered. I even told her that that
<v Speaker 2>manly when we were dealing with the white flowered kind
<v Speaker 2>of serious a while before. But yeah, that's that's a
<v Speaker 2>remarkable find and a remarkable discovery.
<v Speaker 1>And it's it's so unique too. I mean, it's it's uh,
<v Speaker 1>you know, sunflower family ast racy. It's only got anybody listening.
<v Speaker 1>It's got these Really it's a really wooly plant, as
<v Speaker 1>you would expect from a limestone desert area, and it's
<v Speaker 1>got only two to three ray floor its per head,
<v Speaker 1>so like these, and they look like these long what
<v Speaker 1>someone who doesn't know about the sunflower family intricacies might
<v Speaker 1>think is just a pedal, but two or three of
<v Speaker 1>these long, candy cane striped rays that are almost twice
<v Speaker 1>as long as the flower head coming out of these heads.
<v Speaker 1>It's really weird. It's a really bizarre plant.
<v Speaker 2>And not only is it restricted and distribution, and it's
<v Speaker 2>remarkable for that reason, but as you just said, it's
<v Speaker 2>a remarkable discovery for the whole family pastor racey because
<v Speaker 2>of its position.
<v Speaker 1>And came up close to silostrophy.
<v Speaker 2>Closest to p ssilostrophy, that's correct, but not really close
<v Speaker 2>to silostrophy, and so within that subtribe of composity. It's
<v Speaker 2>an unusual discovery, and of course there's remarkable morphology as well.
<v Speaker 1>Is are there any guesses or has anybody talked about
<v Speaker 1>how how long ago it might may have diverged from ssilostrophy.
<v Speaker 2>I think we've all guessed about that, I think, and
<v Speaker 2>of course Isaac lictor Mark has a good idea from
<v Speaker 2>the DNA sequencing data that it's primitive, but how long
<v Speaker 2>it's always hard to tell. I think we need to
<v Speaker 2>be sure about other distributions or distributional rangees, because it's
<v Speaker 2>it's so inconspicuous that and it's a it's a winter
<v Speaker 2>blooming femeral, a very delicate annual apparently judging from its
<v Speaker 2>root system, we have real short, slender, little root that
<v Speaker 2>moodanists are not out at that time of year, looking
<v Speaker 2>around very much and little. As you mentioned already, it's
<v Speaker 2>very small and wooly, covered with hair, whitish and resemble
<v Speaker 2>seedlings of many other wooly plants, plants that have a
<v Speaker 2>lot of pubescentce wooly pubescence in the Shuahuan dead northern
<v Speaker 2>Chiwuahuan does it region.
<v Speaker 1>It's weird that a blooms in winter and this is
<v Speaker 1>not normally a winter rainfall area.
<v Speaker 2>It's not, but even though it rains a little bit
<v Speaker 2>or snows are used to at least in the fall
<v Speaker 2>late fall and in the winter as well. Sometimes pretty
<v Speaker 2>good snowfalls in February in the rain in February. But
<v Speaker 2>we have other winter blooming species here as far as
<v Speaker 2>I can remember, all of them are perennial, but they
<v Speaker 2>bloom in the winter, and we're poorly known too until recently.
<v Speaker 2>There's a cactus variety that occurs in blooms in February
<v Speaker 2>as well. What is which one is that ancestral cactus
<v Speaker 2>sclero cactus depending on your terminology me to rerevia Mattis
<v Speaker 2>variety pallida, which we described.
<v Speaker 1>Here, and it's got white flowers or as.
<v Speaker 2>White flowers, and it's a limestone endemic apparently, but it
<v Speaker 2>occurs in minute to vaculate as well.
<v Speaker 1>Wow, how rare.
<v Speaker 2>It's widespread, and it's difficult to say how rare it
<v Speaker 2>is because of that, but it's one rarely encounters it
<v Speaker 2>in limestone. It seems to be quite rare, s put
<v Speaker 2>it that way.
<v Speaker 1>So it's got a broad distribution, but it's just sporadic
<v Speaker 1>or what sporadic and the white flower do you think
<v Speaker 1>that's a Is that some sort of special specialization towards
<v Speaker 1>moths or is it?
<v Speaker 2>That's always a good question. It's it's some and a
<v Speaker 2>genetic accident. Of course it was selected for and why
<v Speaker 2>It's always hard to determine, but that that makes sense
<v Speaker 2>to me, both of those things.
<v Speaker 1>Is it a night bloomer do you know?
<v Speaker 2>No, it's not a night bloomer as far as I know,
<v Speaker 2>And we have grown it too from seed and I've
<v Speaker 2>I've looked at it and watched it. But cratypuscular activity.
<v Speaker 2>It could be it could be involved with moss. I
<v Speaker 2>don't know. But it's relatives are yellow flowered mm hmm.
<v Speaker 1>I've always wondered about that. Why certain flowers or certain
<v Speaker 1>plants will have the majority of their population, you know,
<v Speaker 1>a color, and then there's this, you know, phenotype that
<v Speaker 1>pops up that's white. It's like, what it's what selects
<v Speaker 1>for that? I mean, I could just think of moths,
<v Speaker 1>but maybe there's other things selecting for it too, who knows?
<v Speaker 2>Yeah, or maybe there is no. It could still be
<v Speaker 2>an accident and it could be persisting for no selective reason.
<v Speaker 2>So it's it's always difficult to say that that we can.
<v Speaker 2>We know a lot of instances where certain things seem
<v Speaker 2>to be true. But there are a lot of white
<v Speaker 2>flowered individuals and populations of all kinds. I was looking
<v Speaker 2>into that recently in connection with some other things that
<v Speaker 2>we were doing, including a white flowered strawberry patalia. One
<v Speaker 2>white flowered strawberry patalia when thousands, tens of thousands of
<v Speaker 2>individuals are always deep magenta in color, and so there's
<v Speaker 2>all those betaline pigments are present or else they it's
<v Speaker 2>a it's a it's an accident, it's a I hate
<v Speaker 2>to call it a mutation, but it's a phenotype thing there.
<v Speaker 2>And it has more than one pigment in there too,
<v Speaker 2>probably so it.
<v Speaker 1>May hop up, but it doesn't become dominant in the
<v Speaker 1>population lesson I select for it. So I do want
<v Speaker 1>to get back to a vicula. But before I forget,
<v Speaker 1>I want to talk a little bit, just a little
<v Speaker 1>bit on moth pollination, because there's a lot of moth
<v Speaker 1>pollination in the Chihuahua desert, which I think is fascinating.
<v Speaker 1>Salvia white housey eye. Have you noticed I've seen that
<v Speaker 1>getting pollinated by sphinx moths.
<v Speaker 2>Oh really, I have not seen that.
<v Speaker 1>Manda villa. What is that out here? No, macrosciphon mana macrocyphone.
<v Speaker 1>There's a ton.
<v Speaker 2>Yeah, there's several of them actually, all.
<v Speaker 1>The onantheras, all the nicktags. It's a really have there
<v Speaker 1>been many people studying that.
<v Speaker 2>Siphon and gloss. There are people who study that and
<v Speaker 2>I don't know enough about.
<v Speaker 1>It too, but I mean people coming through sewel Ross
<v Speaker 1>who studied it or hads.
<v Speaker 2>No, not in not far as I know, not specifically that,
<v Speaker 2>but people who do come here and visit here and
<v Speaker 2>visit the herbarium study those kinds of things.
<v Speaker 1>There's a menadora including.
<v Speaker 2>The caterpillars, you know the product of these moths.
<v Speaker 1>Yeah, the menadora. There's a moth pollinated menadora. That's laundrifa
<v Speaker 1>flora acua xanthees. Uh what amsonia?
<v Speaker 2>Right?
<v Speaker 1>So much good stuff? Okay, anyway, okay, so let's get
<v Speaker 1>back to Well, that's like a whole podcast on its
<v Speaker 1>on its own. Yeah, it seems insane to touch on
<v Speaker 1>it for but I just wanted to put it out
<v Speaker 1>there to get in people's brains so this so viculous.
<v Speaker 1>So you grew this too. The seeds are tiny on
<v Speaker 1>this new species, but really really small. Correct need a
<v Speaker 1>dissecting sculpt to look at them. What what did you know?
<v Speaker 1>I mean, I'm amazed that you were able to not surprised,
<v Speaker 1>but amazed you were able to grow this. What was
<v Speaker 1>your method? What do you what? Do they seem to need?
<v Speaker 2>Just the usual method for me is fotting medium, try
<v Speaker 2>several seeds. Of course, what I did first was to
<v Speaker 2>get filled the kenes or sipsila, that's the fruits of
<v Speaker 2>a composite, and the seed is a single seeded fruit
<v Speaker 2>on the inside of the kene, so we can call
<v Speaker 2>them seeds just for and if they're filled, then you
<v Speaker 2>can assume that they're fertile and should germinate. But they
<v Speaker 2>may not be fertile just because they're filled, so they
<v Speaker 2>have to test that. And these winter annuals logically could
<v Speaker 2>require a cold season to overcome dormancy, and for that
<v Speaker 2>we do coal stratification and I use just refrigerator temperatures
<v Speaker 2>to substitute for formal coal stratification, lack in a potting
<v Speaker 2>medium and under chill temperatures. So that seems to work
<v Speaker 2>for a lot of navy plants. So I did the
<v Speaker 2>usual thing there, there's nothing extra. But I did plant
<v Speaker 2>several seeds in several pots before any of them germinated,
<v Speaker 2>and all the time they were in the refrigerator. So
<v Speaker 2>the coal stratification or the refrigerator temperatures after about three
<v Speaker 2>months seemed to be more effective. It could just be
<v Speaker 2>an artifact of time. I have no idea, really, But
<v Speaker 2>then I got a pot to germinate with about seven seeds.
<v Speaker 2>I put about maybe ten, I don't remember, and some
<v Speaker 2>of them damped off right away. It's as though the
<v Speaker 2>little tiny radicals couldn't penetrate the substrate.
<v Speaker 3>That's the way it looked.
<v Speaker 2>And of course I'm growing these at home in a
<v Speaker 2>window sill where I could look at them as often
<v Speaker 2>as necessary, and at ease facing window exactly southeast. Well
<v Speaker 2>not even a greenow. They just loved that early morning sun.
<v Speaker 2>Almost everything does. So anyway, four of them finally survived,
<v Speaker 2>four of the little seedlings, and one grew faster than
<v Speaker 2>the others, and others three and then the one quickly overcame.
<v Speaker 2>We'll say two of them established very nicely and pretty
<v Speaker 2>good sized plants. And the third and fourth were lagging behind,
<v Speaker 2>but probably crowded out and shaded too much by the
<v Speaker 2>larger plants. But I had four plants originally, and that's it.
<v Speaker 1>And so when you were cold stratifying these was it
<v Speaker 1>Were they in soil or just just bare seeds.
<v Speaker 2>In a in paper And actually it's quite envelope envelopes.
<v Speaker 2>We used to put seeds always in paper, but in
<v Speaker 2>a refrigerator. I put them in a plastic bag as
<v Speaker 2>if lock and I don't zip it shut in case
<v Speaker 2>if it don't want water to accumulate. But it protects
<v Speaker 2>them a little bit in the paper from the cold
<v Speaker 2>temperatures and keeps them a tiny bit moist or moist.
<v Speaker 1>It's alister. You want them to be a slightly moist,
<v Speaker 1>not wet, but moist, and that helps with the cold.
<v Speaker 2>If I were doing real colt ratification with wallets, let's
<v Speaker 2>say native wallets, I would put them in the maybe
<v Speaker 2>a tray and potting medium, moisten the potting medium, and
<v Speaker 2>put them in a refrigerator and they would if you
<v Speaker 2>didn't get the mouth, they'd probably germinate for very long. Yeah,
<v Speaker 2>under those conditions. The moisture, so just.
<v Speaker 1>Three months in a paper envelope in the fridge, and
<v Speaker 1>that seemed to work well.
<v Speaker 2>That worked for these and it could be that they
<v Speaker 2>would have maybe those particular ones would have germinated. Anyway,
<v Speaker 2>this is not scientific, you know, we would do trial
<v Speaker 2>and error and both kinds of things. But that's that's
<v Speaker 2>just a standard thing that I do, is called stratification,
<v Speaker 2>so that I call it anyway in the refrigerator because
<v Speaker 2>it's required for so many of our natives. Anyway, up
<v Speaker 2>they came, and I do have a few more seeds,
<v Speaker 2>so I'll try try it again.
<v Speaker 1>And then you could probably get seeds off the one,
<v Speaker 1>this one that you've got growing now too.
<v Speaker 2>Well, if you have two plants. But also found out
<v Speaker 2>by growing them that they're self incompatible. And we didn't
<v Speaker 2>know any of the biology about Ovicula by radiator because
<v Speaker 2>it was, as you noted, it was discovered in March
<v Speaker 2>March second by this remarkable pork volunteer, and and so
<v Speaker 2>there was no in it. Right away. It got very
<v Speaker 2>hot and dry in its habitat, and it started messing
<v Speaker 2>right away, and before long it was gone, and there
<v Speaker 2>was just nothing left of it except the wooly little
<v Speaker 2>balls that were present there, and so we know, but
<v Speaker 2>nothing biological about it, you know, it's it's life history.
<v Speaker 3>How did we know that much?
<v Speaker 1>How do you think? Because that pod that I saw,
<v Speaker 1>there's what four individuals in there? How'd you figure out
<v Speaker 1>it was self incompatible?
<v Speaker 2>There was only two plants in flower at the time,
<v Speaker 2>and something has to pollinate them, or something has to
<v Speaker 2>pollinate them, you know, like an insect of some kind.
<v Speaker 2>But there are no insects as far as I know
<v Speaker 2>in my window cell. And what I did was take
<v Speaker 2>the older plants, the older heads of the plants that
<v Speaker 2>had been there long enough to develop the fruits, and
<v Speaker 2>look in the heads. There are seven of them, I think,
<v Speaker 2>and not a single seed developed. At the same time,
<v Speaker 2>I also crossed some of the two plants that were
<v Speaker 2>in flower and mark them with reds, which is a
<v Speaker 2>habit I used to do to mark things. That's one
<v Speaker 2>good way to mark them, tie a thread around the
<v Speaker 2>head or around the peduncle of the head, so way
<v Speaker 2>I did with prittlies and other composites. But these were
<v Speaker 2>too small to do that, so it was not an
<v Speaker 2>absolutely correct kind of thing. And then later, as a
<v Speaker 2>matter of fact, just less than a week ago, I
<v Speaker 2>picked those heads, and I haven't examined them yet, so
<v Speaker 2>we can find out if they can be artificially crossed
<v Speaker 2>that way.
<v Speaker 1>What were you using to artificially cross them?
<v Speaker 2>I rubbed the heads together. Okay, there are all kinds
<v Speaker 2>of ways to do it, the brush or any kind
<v Speaker 2>of thing to get pollen from one to the other
<v Speaker 2>and put them on the stigmas of developing disc flowers.
<v Speaker 2>So anything that works for that.
<v Speaker 1>Are the marginal floorrets, because the marginal floorts are just pistilate, right.
<v Speaker 2>The marginal floorits are pistolate, two or three of them,
<v Speaker 2>and they two are fertile. They're pistelate and fertile. And
<v Speaker 2>I could determine that from the original material that we
<v Speaker 2>had to describe write a description for the species.
<v Speaker 1>And the disc floor its are hermaphroditic but fertile. Correct.
<v Speaker 1>And so these seeds, I mean that one growing now
<v Speaker 1>might be the only one in existence at this very
<v Speaker 1>dry time of year.
<v Speaker 2>So far as we know, the only they're the only
<v Speaker 2>plants living today, that's correct.
<v Speaker 1>That's not in seed form, right, The rest are just.
<v Speaker 2>Not in seed form, that's correct.
<v Speaker 1>I wonder how long the seeds if some of these
<v Speaker 1>can live.
<v Speaker 2>It's a good, good question we need we'd like to
<v Speaker 2>find that out, of course, and we can do it
<v Speaker 2>experimentally given a little time. But logically, you know, just
<v Speaker 2>from other kinds of composites, these seed coats are very thin,
<v Speaker 2>so I expect fability is not very long, maybe a
<v Speaker 2>year or two or three or four.
<v Speaker 1>Because I normally think it doesert plants having very long
<v Speaker 1>lived seeds.
<v Speaker 2>But they do, and especially if they have fairly thick
<v Speaker 2>seed coverings. There's more than just being you know, there
<v Speaker 2>are different kinds of dormancy, of course, and one of
<v Speaker 2>the most effective in these desert climates is mechanical dormancy
<v Speaker 2>through thick sea sick seed coats. All of our legumes
<v Speaker 2>have fairly thick seed coats, right to me. Overcome that
<v Speaker 2>easily by filing or snipping the seed coats drems. Yeah, yeah,
<v Speaker 2>rub them on a brick.
<v Speaker 1>I just did that with theirmount of Phylum I collected
<v Speaker 1>near Fort Davis. And yeah, the population out here even
<v Speaker 1>looks like a different ecotype. It's a much hairer than
<v Speaker 1>you'd find.
<v Speaker 2>This is Mountain Laurel, cold hardy compared to Central Xas.
<v Speaker 1>Yeah, Texas they are all the ones I scarfight came up,
<v Speaker 1>So yeah, I want.
<v Speaker 2>To how did you do it?
<v Speaker 1>Just a dre Oh yeah, yeah, held it in like
<v Speaker 1>a plumber's wrench, and then you could use advice too,
<v Speaker 1>and then.
<v Speaker 2>Just went in there and smart that is. I use
<v Speaker 2>a three corner file, just.
<v Speaker 1>A dremal, just to the point that you can see
<v Speaker 1>the endosperm.
<v Speaker 2>And commercially, people that do that use an acid, sulfuric acid,
<v Speaker 2>and yeah, it's the seed coats that way, but it's
<v Speaker 2>kind of a nasty way to do it to me.
<v Speaker 1>Yeah. Yeah, that's a that thermount of phylum that you
<v Speaker 1>found on gyps And just going back to that, is
<v Speaker 1>that same species or is it a different one that's
<v Speaker 1>in the Guadeloupees.
<v Speaker 2>It's a different subspecies, different or as we describe them, varieties.
<v Speaker 1>But they look notably, they're quite.
<v Speaker 2>Similar in appearance, but they are different enough to be
<v Speaker 2>at least and of course they're geographically isolated, and so
<v Speaker 2>they're different enough for us to call them varieties.
<v Speaker 1>I wonder how that species would do in cultivation, because
<v Speaker 1>it seems like it would probably be a great horticultural
<v Speaker 1>specimen from their plant.
<v Speaker 2>I think it would be yes, I don't have any
<v Speaker 2>viable seeds of either one of them. Now we do
<v Speaker 2>have the.
<v Speaker 3>Specialist or her burial.
<v Speaker 1>You've got to go out there and get get some
<v Speaker 1>seeds either one of those populations.
<v Speaker 2>Yeah, I can tell you exactly where it is in
<v Speaker 2>Mexico and.
<v Speaker 1>How far over the border from, oh, you know, thirty minutes.
<v Speaker 2>I think it's I can look on the label. I
<v Speaker 2>think it's a certain number of miles from the railroad
<v Speaker 2>tracks across the highway.
<v Speaker 1>M hmm, yeah, I've seen that special.
<v Speaker 2>Okay, so it's then you can't miss it because it's
<v Speaker 2>right by the road.
<v Speaker 1>And it probably looks unique too.
<v Speaker 2>Just oh yeah really, and they are big shrubs.
<v Speaker 1>Any plant person would probably stop and be like, let's chat.
<v Speaker 1>So well, I could talk to you for another three
<v Speaker 1>hours here, but I won't do that to you. So
<v Speaker 1>I really appreciate you being willing to come on to
<v Speaker 1>this podcast. Is there anything you'd like to say before
<v Speaker 1>we dip out here or any inspiring words to young
<v Speaker 1>people who are getting excited on Texas.
<v Speaker 2>By plants are great. It's always something something exciting going
<v Speaker 2>on with plants.
<v Speaker 1>Try to grow them, collect their Buryingboucher's.
<v Speaker 2>Feel work, growing plants, all of those things. There are
<v Speaker 2>many things that aren't known yet
<v Speaker 1>As we've seen species being discovered, and yeah, well all right, well,
<v Speaker 1>doctor Powell, thank you so much, and everybody else they
<v Speaker 1>have agrest today
