of buckwheats and butterflies

Eriogonum parvifolium (var. parvifolium)
Polygonaceae

edited 11/25/14 -  I've made a public fool of myself.  And, I'm okay with that.  Sharing my journey may help someone else learn something new about themselves, or about the world around them.  Sincere apologies to those who have read through my numerous emotional incarnations of pure drivel as I worked all of this out in a very public space.  I do thank you for your time.

The embarrassing kicker is that my experience could be the perfect demonstration, p-e-r-f-e-c-t, of the perils of ID based on observable traits.  Art Shapiro kindly pointed out to me, "Your essay is no surprise to me. Laypeople often think taxonomy is just naming and identifying distinct entities in Nature (for the religious, add "as created by God"). Well, it ain't. DNA sequencing has underscored that! I've been teaching students since 1972 that "if species weren't messy, we'd have no reason to believe in evolution." Subspecies are even worse. In the heyday of the Neo-Darwinian Synthesis, taxonomic subspecies were viewed as species in statu nascendi. Some folks understood way back then that being recognizable to a taxonomist had no necessary implications regarding genomic differentiation. Now we KNOW that. Do you want me to go on?!"

I read this last night, and it made absolutely no sense to me.  Then, it hit me how I've been understanding all along that Art's got some bugs in his 40+ year transects that look nearly identical, but are not the sameI know this.  He also sent me one of Jim Reveal's old papers about the amazing sequential evolution between butterflies and their host plants...  Oh, my God!  How could I have been so blind?  It's fascinating to look at my own deep-seated beliefs compared to what I think I know intellectually.  They don't match!  It's crazy making.  I was at a point of complete frustration, and I'm glad Art spoke up in such a direct way.  Maybe other people have been telling me all along, and I just haven't been listening?

I can't believe I never saw this before, because I'm fairly self-reflective.  I've always considered myself firmly in the evolution camp ever since my junior year of high school (1987-1988), and a handful of us asked our Mormon AP biology teacher for his opinions of evolution vs. creationism (now disguised as intelligent design), which had been the topic of a recent US Supreme Court ruling (Edwards v. Aguillard).  To be honest, I hadn't given this much thought since then, even though my college degree is in the sciences.  You'd think I'd know better.  However, I was raised in a conservative Christian family (the 700 Club, laying of hands, speaking in tongues, no drinking alcohol, no secular music in the house, no reading LOTR, etc.).  I'm definitely not that way today, but it's funny how the cultural beliefs of the people I've been around have seeped into my subconscious.  It's ironic for a blog titled Nature ID, as in identification, not intelligent design.  Have I been subtextually promoting intelligent design?  This was never my intention.  I need to reevaluate.

Art sent me a follow-up e-mail that explains things pretty well for me.  I've edited it for brevity. He says, "...we have learned in the era of "barcoding" (if you're unfamiliar with it, search the term) that the number of apparent genetic species is often larger than the number of taxonomic species, because cryptic or "sibling" species are often concealed by one phenotype. That is, the phenotype has been constant while the genome overall has changed a LOT. Surprise! Here's a bird example--a bird!  ...The whole thing started with butterflies, but it has now expanded to everything (my naming usage follows the genetics for herps). On the other hand, taxonomic subspecies may be dramatically different in phenotype, but virtually identical genomically, because those conspicuous differences are caused by just a few genes under strong selection, superimposed on a constant genetic background..."  Wow.  Just wow.  My mind is blown as to how I knew about this, yet haven't actually applied it to my hobby cum citizen science project turned hopeful serious science project that can be peer-reviewed and funded.

So, does anyone know who is currently doing the DNA on buckwheats in CA?  Is this buckwheat genetically different than the one Smith's needs, even though its superficial physical characteristics match what's found right along the coast?  I'm still curious to see if the buckwheat(s) that Smith's actually uses (or can use in situ, with potential drawbacks) is the one that's being planted for mitigation as it's currently practiced.  I owe the two CNPS authors an apology for making such a fuss (but not for pointing out their error - I wish I could be more diplomatic).  I'll have to ask around if anyone has already tested this idea, because I'm not sure the authors know themselves.  Otherwise, wouldn't they have just pointed that out, instead of hanging their hat on the amount of hairiness?  Does anyone know?

With this kind of potential discrepancy, how can we use physical features and observations in the field and for what purpose?  How do we separate what we see with what we know is continually changing and evolving?  How do we assign names to each defined entity for the sole purpose of clear communication?  Have we lost the original definitions and intent of common names vs. scientific names in the age of digital photographs, online sharing, and public outreach in the form of organized counts and BioBlitzs?  Are field guides (and all their online incarnations) really just a 1950's era hobby that have little to no basis in science as we understand it today?  Do they keep the layperson lay?  Eh, maybe some of these questions are too much of an exaggeration, but is there truth in there as well?

As humans, I think we have an instinctive need to identify things, although our ability to do so is not always intuitive.  What are you?  It's in our nature.  Maybe I want to stay lay, because I've been having so much fun tacking on names to everything?  It's like a game.  Heavy, heavy sigh. I'm going to leave my post below as I had last edited it (including the incidental original religious references and the late ps) as a true testament to the perils of ID from a layperson who got led astray by her own righteous beliefs as she tried to find her way back to science on her own.  Ha!

Seacliff buckwheat was my very first buckwheat ID on Nature ID.  I've come a long way since then in learning about the local nature.  As you know, I rely on photographs rather than keys for most of my IDs.  I believe my process and methodologies have served me well in the 5 1/2 years I've been doing this blog, specifically designed to be my personal learning tool.  I've been able to quickly recognize seacliff buckwheat ever since this spring with my numerous casual trips down the coast, looking to learn the local buckwheats and butterflies.  It's a common native plant around here.  And, it has caused me more headache than you can possibly imagine. 

To me, this shrub's leaves have a distinctive cobwebbiness to the topside (adaxial - with a 'd', as in dorsal) that can sometimes look like it's been partially rubbed off to a shoeshine, and underneath (abaxial - with a 'b', as in belly) there's a thick cottony felting that can sometimes be so thick it extends down the woody stem.  It just has a look that is much easier to recognize than it is to describe in words.  Granted, there are at least two forms I recognize around here, this one shown here with the narrow-arrow leaves (Mortuary Beach) and another one with really fat/wide round leaves mainly from online photos and a vague recollection of having seen it adjacent to the ocean (Point Lobos, Asilomar, gardens?).  If I were to assign a common name to each form, this narrow-arrow one I would call seacliff buckwheat (I find it really does grow on steep hillsides that have any hint of marine influence, i.e. right up from the water to extending inland at least 12 miles or more), and the round one I would call dune buckwheat.  Neither shrub form should be confused with the similarly-and-confusingly-named perennial herb coast buckwheat, aka seaside buckwheat (E. latifolium), a common mistake that I've noticed online. This is all fine and good that I can recognize these by sight.  However...

Through a series of communications for my research permit application as required as part of my agreement with my Monterey Co. butterfly site (not Garland Ranch), it's come to my attention that the local CNPS folks believe this is CA buckwheat (Eriogonum fasciculatum) and more specifically, var. foliolosum.  Nope.  I went back and checked their local field guide, their CNPS-endorsed website, and a draft that was sent to me of the Monterey Co. wildflower bible revision that one of them is updating.  They are correct in recognizing the rounder form as dune, which is fine.  But, I can clearly see they have the mistaken impression this narrow-arrow form of seacliff buckwheat (E. parvifolium) is CA buckwheat (E. fasiculatum), two different species.

In my experience, that multi-toned pink, tight pom-pom shape they show in their "CA buckwheat" photos is distinctive of the mature summer season's seacliff buckwheat, and I have never seen that flower head on CA buckwheat, which tends to be looser in shape (ex. of comparable summer season CA buckwheat).  I asked around and have been informed by people who have grown buckwheats for decades that these two species do not hybridize.  I specifically went to Terrace Trail at Garland Ranch's Garzas Creek access on 11/17/14 just to take these diagnostic photos (see also at the bottom of this post), because this is the location I was told by one of the CNPS authors where he's found CA buckwheat.   I was fully prepared to find CA buckwheat (and actually hoping!), but I didn't.  I found this narrow-arrow seacliff buckwheat, instead.

The Garland Ranch wildflower field guide has been very useful to me as I learn the local plants.  I make no qualms that it's well-designed and one of the best ones available for our area.  I would recommend it to anyone interested in local wildflowers.  With that said, I do think the authors' mistake makes it impossible for anyone to ID the local buckwheats by using their guides.  What I've seen of the wildflower bible revision draft, which is a CNPS publication, is misleading and could be improved.  I hope they get that fixed, but not likely.  I tried my best to explain and provide evidence as to why I think their ID isn't right, but they maintain they're correct in calling it "CA buckwheat".

Here's the thing, I have been staring at real CA buckwheat at Pinnacles every single week going on 8 months now and looking at thousands of my own pictures and others' online of CA buckwheat from all over the place.  While I still may not always be able to distinguish Pinnacles' var. foliolosum (the local CNPS ID, btw) against var. polifolium, I know CA buckwheat (Eriogonum fasciculatum) to species, in person and in photographs, through the seasons.

I've also consulted with photo-documentarians for the Eriogonum Society, the National Park Service, and CalPhotos.  Even if they're unfamiliar with seacliff, they have confirmed it is not likely CA buckwheat, which is more common and familiar in SoCal.  I've been utterly amazed at how many people don't actually know how to distinguish buckwheats (or are not willing to say on record). Hey, I don't know all of them either, but a handful of the larger local buckwheats are really obvious to me now that I made it my mission to learn the local buckwheats this year.

Given the continuing disagreement over this ID, I had to seriously consider the possibility that the local CNPS authors could be correct in their determination, especially considering one is revising the local wildflower bible and many people defer to their opinions, including the folks at my Monterey Co. butterfly site.  Their insistence made me question my own observations, because I know I make mistakes, too.  For my own peace of mind, I needed to double-check what I felt I already intuitively knew, so I took the time to research the keys and figure out the dizzying array of taxonomic terms.

Basically, it boils down to leaf shape.  Simple as that.  When keying to species (not variety) between the two, forget what you hear about amount of fasciculation or hairiness/tomentoseness (remember, hard to describe in words).  The Jepson eFlora keys out E. fasciculatum at 60/60' with "Leaf blades narrowly linear to oblanceolate".  Additionally, eFloras of North America keys out similarly at 20/+ with an additional statement under the species description for E. parvifolium, "blade lanceolate to round".  Linear and round are pretty obvious, and the above is neither.  Now, google images or take a look at this exaggerated graphic between lanceolate and oblanceolate.  The leaf shown above is clearly lanceolate (aka narrow-arrow), therefore E. parvifolium.

I also reached out to Jim Reveal, the author of Eriogonum.  For additional reference, here are his original descriptions, from which I believe most every key depends for EriogonumE. fasciculatum and E. parvifolium E. parvifolium has not been keyed out into varieties, and Jim told me he doesn't officially recognize them.  With that said, there were certain forms or phases he did recognize in the past, until he was shown examples that completely graded with each other.  For my own edification, here's how I understand it: var. parvifolium ("thickened leaf blades" and "compact clusters of involucres containing white to rose flowers", this is the narrow-arrow form I find common around here in the wild), var. crassifolium ("compact and dense mat-forming", is this a round one found in the sand? I don't know), var. lucidum ("yellow flowers" with round leaves, also found here with a white phase, too, according to Jim), and var. paynei ("white-flowered inflorescences", and "more graceful habit", found down in Ventura Co. and is supposed to be large).  I'm guessing this elegant white phase shown here on Terrace Trail at Garland Ranch may just be how "var. parvifolium" grows in protected, shadier places, because it has the same leaf shape as the shrubbier pinker one I find on exposed sunny hillsides that Jim confirmed the ID for me via my photos.  Again, seacliff buckwheat varieties are not formally recognized.

So, why is this plant such a big, huge, deal for me to go to all this trouble?  

Six words: the federally endangered Smith's blue butterfly.  The seacliff buckwheat (Eriogonum parvifolium) is its host plant.  There is only one person in the entire country who has ever been granted a permit to study this butterfly and in essence even be around seacliff buckwheat for research purposes (I may be exaggerating slightly, but you get the picture).  While I'm sure he's done a lot of good, he's also made quite a tidy business over his legally-mandated monopoly.

The fact of the matter is, there are very few people who could see a blue butterfly and know it is or is not Smith's.  I believe I could eventually tell, only if I could be allowed to get close enough and take enough photographs as absolute substitutes for physical specimens.  It's worked for me with buckwheats, why can't it work for me for butterflies?  Gotta start somewhere for baseline info.  Let someone else do a specific collection to work out the genitalia and genetics if anything unusual is seen.  I've heard that merely taking photographs of this endangered butterfly can be considered as "take" by the USFWS, a strict no-no.  Sigh.  It sure seems silly that the very laws created to protect an animal keep us from learning more about it.  Something is seriously broken in the system.

Hey, I'm not even particularly interested in Smith's, but I discovered seacliff buckwheat is the dominant native nectar source for butterflies at my Monterey Co. site (again, not Garland Ranch).  I can't study the other butterflies without getting near Smith's listed host plant, and if they are there, either in flight or potentially trampling over delicate pupae around the buckwheat bushes.  I wonder if we might even have one of the square-spotted blues (Euphilotes battoides) in the area, which isn't reported for anywhere near here, but that may be because no one admits to looking close enough over fear of Smith's restrictions.  They do look a lot alike.  The selfish solution for me is to see Smith's delisted, but it's all entangled with political and financial motives. 

The federal permitting process for Smith's is essentially non-existent and shrouded with stories of how impossible it is to jump through the hoops to meet their requirements.  They require experience to get the permit, but no one can get the experience without the permit or threat of jail and financial ruin.  Catch 22.  From several people, I've heard hushed horror stories about closet lepidopterists who live in fear and flatly refuse to cooperate with other researchers over concerns of being raided by federal agents.  I have no way of knowing if any of these stories are actually true.

These stories not only hamper research to learn more about this rare butterfly, they may also hamper the information made available about its host plant.  I figure there must be some antiquated law about not being able to update listings based on new findings.  Gordon Pratt believes the listed species (Euphilotes enoptes smithi) is not the one that's actually rare, but he told me he was talked out of delisting by the USFWS.  Smith's close relative (Euphilotes enoptes arenacola), which he helped describe, that feeds on coast buckwheat (E. latifolium) in a small sandy area in Marina is the one that he believes is truly endangered, and Smith's law protects it, too.  Likewise, I wonder if there was pressure on Jim Reveal to not reveal (pun!) his buckwheat variety designations, because it would further complicate the listed identity of several endangered butterfly host plants.  I asked him directly, but his answer shed little light on the question.  The reason why I came to this conclusion is because Jim goes into such mind-boggling detail for the various buckwheats and their varieties (case in point, sulphur buckwheat/E. umbellatum has 45 keyed varieties as of 2002), and yet for the seaclifff (E. parvifolium) and coast (E. latifolium), nothing, nada.  They are as they are, no variety designations, even though there's obviously different forms.  You'll notice that both of these buckwheats are host plants for endangered butterflies (real or listed).  Or, maybe even he can't get a research permit to study the plants that the endangered butterflies need?  I don't know, but there's gotta be more to the story.  I believe this lack of variety designations for seacliff, when there are so many for other buckwheats, confuses a lot of good plant people who may only be familiar with the round dune version. 

So, maybe Smith's blue is a common butterfly around here, who's to truly say?  Without hardly trying, I have twice found the earliest seasonal record for Smith's blue, once in 2003 and again this year 2014, the only two years I've gone down the coast with the specific purpose to look for various butterflies (hey, I've been busy pursuing other interests in the intervening 10 years).  I personally suspect Smith's is way more common than anyone realizes considering the locally recognized "CA buckwheat" is actually seacliff buckwheat.  Maybe people haven't been looking in the right places for the butterfly?  In any case, I imagine there might be some wealthy landowners out there who were relieved to find out they had "CA buckwheat" and not seacliff buckwheat on their property when it came time to do their EIRs before they developed.  Eh-hem.

On the flip side, I have a hunch CA buckwheat (E. fasciculatum) in Monterey Co. is not as common as is reported by the local CNPS chapter, unless it's found along the highway where it's been planted by Caltrans and maybe further south towards SLO.  eFloras also cautions that var. foliolosum is, "a potentially aggressive weedy shrub, efforts should be made to curtail its introduction into areas outside its native range."  I worry that good-intentioned native gardeners, seeing it listed as occurring here, will plant the not-native to this area weedy CA buckwheat, where it could easily escape and compete with the locally native seacliff buckwheat.

Most importantly, the narrow-arrow form that is mistaken in our local books for "CA buckwheat" is, in fact, the seacliff buckwheat form that I have personally seen Smith's blue on and is in all the photographs I can find online where the butterfly is actually on the plant.  Yet, when E. parvifolium is shown without the butterfly for illustrative purposes of the reported host plant, the round shape is chosen to be used.  Peculiar and possibly misleading.  I'm thinking that's because the round dune form is the one people first think of for E. parvifolium, very likely due to the famous El Segundo blue's round dune use down south, which had a spectacular CA buckwheat fail.  I worry folks are planting the round dune up here as part of mitigation based on the El Segundo experience, when really the narrow-arrow is what Smith's uses.  And, that's not to imply all narrow-arrows are used by Smith's. So, if anyone needed to do restoration or mitigation work as required by law, they'd be pulling out the narrow-arrow seacliff buckwheat fully believing it's the weedy "CA buckwheat" and planting the round dune form, which could possibly be the wrong seacliff buckwheat form for Smith's.  I'll admit, I don't actually know if this happens here with Smith's, but who does?  

It would have worked in my favor if this really had been CA buckwheat.  Despite my desire to be correct, I was actually hoping I was wrong, because then I'd have no need to apply for a federal permit for my butterfly site.  Problem solved.  But, I'm not okay continuing to call it "CA buckwheat" just because other people say so.  That's just bad research.  If I had only kept quiet, I might have been able to make nice-nice with the local CNPS folks.  Although, at this point, with the way they dismissed all my research and documentation, I don't feel they have earned, nor deserved, my trust.  I'll admit, I made a bit of a fuss as I was attempting to get them to see reason.  I can be very pushy in getting things correct, and it does not do me any favors in winning over people.  I've pretty much burned that bridge.  Erm... torched?  

Such as it is, imagine for a minute, the ripple effect this simple ID error has... 

Their expert plant advice (books, online, in person) is probably followed by many environmental consultants who do EIRs and restoration-type work (if you believe they know better, I have a burnt bridge to sell you), who then also mistake this buckwheat ID, which ends up determining the fate of the land all based on a plant name, potentially costing millions of dollars (or making others billions of dollars), and all to the detriment of the very butterfly we're trying to save from extinction.   

This is important!  Does any of this make any sense to anyone besides me?

I sincerely thought I was helping by pointing out a simple correction, like I do all the time when I look up stuff for Nature ID (most people are appreciative).  However, it does beg the question why these old guys, who are no more botanists than I am (they're two fellows with a lot of money who moved here from far away places for retirement), are so adamant that I'm wrong with barely an explanation.  This is not a fight I'm up for.  I wish I could continue with my butterfly studies at my Monterey Co. butterfly site, even if I avoided the seacliff buckwheat like the plague and went searching the brambles for Nymphalids (don't think I haven't thought of this), unfortunately, by doing so, I would not be able to honor the spirit and intent of my private land access agreement. 

As it is, I may have to completely abandon my grand plan to have a companion Monterey Co. butterfly research site in conjunction with my Pinnacles one in San Benito Co., two sites on roughly the same latitude and with similar elevation changes, with similar historical and current cattle land usage, with two native butterfly-pleasing shrubby buckwheats, one cool coastal and one hot, hot, hot, to monitor as the climate changes for the next 20+ years, the rest of my life. Wouldn't that be an incredible data set!?!  

Unfortunately, I'm facing the reality that I will not likely be granted a federal permit anytime soon.  Even if I did manage to get one by some miracle, I would still have to fight the local transplants.  Quite frankly, I feel utterly defeated over this issue and how complicated it got rather quickly.  This has significant personal implications for me, far beyond a simple plant ID or a couple rare butterflies. Have I been overly dramatic?  Sure.  Sob.  At the very least, this hullabaloo has made me rethink my plans and scale down, way down.

Terrace Trail - Garland Ranch - Garzas Creek

Again, I specifically went to Terrace Trail, because this is the location I was told by one of the CNPS authors where he's found CA buckwheat for his field guide.  This is the only type of buckwheat I found on the hillside.  Eh, there might have been an herbaceous buckwheat tucked in there, but remember, I went looking for shrubs.

The photographs below were taken as part of my ongoing effort to better document plants without the need to clip a specimen, bag it, press it, store it for perpetuity who knows where. And, at the point we're taking photographs of dried, dead specimens, wouldn't photos of the living work just as well, or even better?  I feel the same about butterflies, too, and had hoped my method could have been a possible avenue to get federal permit approval.  With the quality of macro-photography these days, I think we need to evolve past collecting things to be hidden away in closets (or for those wary of dermestids and moth balls, in freezers).  Plus, photos are so much easier to share and get feedback.

it's November, so the flower selection is sparse

Does anyone know the name of the stringy brown nest-looking stuff found at the base of the bundled perianths on older buckwheat flower heads (last photo here)?

(must look at individual leaf to really make that determination)

contrary to what the local bible says, I believe seacliff is often fasciculate

(note V-shaped cyme with flower clusters half-way up)

ps - For the evolutionary biologists out there who have a valid criticism that I'm focusing too much on names (man-made construct), when speciation (natural) is in constant flux, I'll concede this post does read like that.  Funnily enough, the names are in flux, too.  Like I've said before, I don't really have the writing skill or vocabulary to describe what I'm seeing, hence, why my photos have served me well. For once on Nature ID, the point of this post is decidedly not about the names in of themselves. Rather, it's precisely because of the confusion over those names that the issue described here becomes real in practical application.

To put it another way, it may be best to substitute species names and varieties (and all the baggage that entails) and simply label each entity as a snapshot in time.  BugX feeds on PlantA.  BugX does not feed on PlantB, nor on PlantC.  Human1 groups PlantA and PlantB together and calls it Plant AB.  Human2 sees PlantB, and calls it PlantAB.  Human2 also sees plant A, does not know Human1 includes it in PlantAB, and then calls it PlantC, for lack of a better alternative.  Human3 wants to save BugX.  Human3 reads that BugX feeds on PlantAB and to remove competing PlantC.  Human3 uses Human2's labels.  Human3 plants more H2's PlantAB (PlantB) and removes H2's plantC (PlantA).  PlantB and PlantC thrive.  BugX no longer has PlantA to feed on.  BugX is not saved.

Does this help explain?  As a repeat reference that helped get me thinking along these lines:

ear-shaped wild buckwheat ~ 11/11/14 ~ Pinnacles

Polygonaceae

I've been on a mission the past many months to learn, really learn to recognize the local buckwheats, given they're so important for butterflies as hosts and nectar sources.  Calflora currently lists 256 spp./var. of Eriogonum in CA, but I've primarily concerned myself with 17 of those listed for my two butterfly study sites.  I have to laugh at how completely lost I was 3-4 years ago when I first started even recognizing buckwheats as a group.  I mean, good golly!  I know I'm not alone with this feeling, because so many people I've talked to have also expressed confusion over distinguishing buckwheats.

Like with most of my IDs on Nature ID, I rely heavily on CalPhotos and various buckwheat image searches on Google and Flickr.  I've been fortunate to learn about local plants in the age of digital photography and internet sharing.  The main problem with photographs is that many are mis-ID'd online and in local field guides.  As a side project, I'm hoping to improve the situation by writing to the various authors and requesting they, at the very least, take another look at their own photos and maybe make corrections, because these mistakes get promulgated and adds to the general confusion.  As with everything else, I try to keep in mind that I could very well be wrong.  Honestly?  I often have to fight the urge to be full of myself, an ugly trait of which I'm not very proud.  Gah!

So, here's the dealio.  Looking at photographs alone is obviously not enough.  As I go out on my weekly study visits, I keep an eye out for newly blooming buckwheats.  They're so much easier to spot when they're blooming, especially the ones that are only 2-3" tall.  No joke.  Plus, just like with butterflies, they essentially sort themselves by timing, so it makes it easier to study them as the seasons progress and to take a closer look at the natural variations.  Week after week, I look at checklists, I look up photos, I look at real plants, I take pictures, and then I look at my photos and compare with existing photos, rinse and repeat.  It's methodical in its own way, and it works for me.  I've been enjoying my autodidactic process.

I believe I now have a decent handle on most of the larger local buckwheats (knee-high or taller) down to species (unfortunately, the numerous varieties are still tripping me up).  In fact, I've been arguing that I can distinguish certain buckwheats by photograph better than the local CNPS experts who trot out less-than-perfect keys with highly confusing and subjective vocabulary.  Eh-hem.  Is it me, or does there seem to be an elitist attitude among botanists who use keys and adore dead, dried, flatten specimens?  Hey, I look at keys, too, but it seems to help to already know what you have in order to follow the key properly.  Seriously.  I regularly read the Eriogonum species descriptions on Jepson eFlora and Flora of North America as a double-check, not that I ever measure miniscule plant parts or entirely understand all the fancy-speak.

"occasionally inflated"
ear-shaped wild buckwheat
E. nudum var. auriculatum

Back in September when the metalmarks were going gangbusters, Gordon Pratt (one of my butterfly go-to pros) suggested different buckwheats to look for as possible hosts, including the protruding buckwheat (E. nudum var. indictum) with inflated stems.  He also cautioned that it's frequently mistaken for another, more common inflated-stemmed buckwheat, the desert trumpet (E. inflatum).  So true!  Even well-respected butterfly folks who are in the business of documenting host plants make mistakes (I believe they show E. nudum var. indictum, not E. inflatum). Please note, naked buckwheats E. nudum var. auriculatum, var. decurrens, var. pauciflorum, and var. westonii can also have inflated stems to varying degrees.

 note the low placement of leaf growth, leaf shape, and type of fuzz on leaves
ear-shaped wild buckwheat
E. nudum var. auriculatum

So, how does one tell the difference?  In the case of the naked buckwheats (E. nudum vars.) vs. the desert trumpet (E. inflatum), look at the leaves.  They're different.  See here and here for what desert trumpet leaves look like.  I'm not even going to attempt to describe it in words, which is why I believe it's often mistaken by those who bother to look past the inflated stems and use a key.  Visually, it's obvious.  It worked in my favor that it had rained over the Halloween weekend, so there were a handful of fresh leaves to examine.  I noticed last week the long-stemmed buckwheat (E. elongatum) had sprouted fresh leaves and wondered about the possibility of protruding, too, which prompted me to get out there again.  The rest of the leaves were dried and impossible to distinguish.

ear-shaped wild buckwheat on a west-facing hill

Protruding buckwheat is not a common plant in CA, nor is it at Pinnacles, either.  I asked Paul Johnson (Pinnacles Wildlife Biologist) about it, and he had a vague recollection from a plant survey done over 10 years ago.  There are two distinct spots on record, one is closed to the public due to condor activity and the other is this hill.  This was my second attempt trying to find this remote patch of protruding buckwheat (which turned out to be ear-shaped wild buckwheat), because my first excursion ended prematurely after I spotted what I believed was a second mt. lion scat pile.  I quickly turned around to more human-populated areas.  Similar to comparing buckwheat leaves, it's easy to spot when something is not, like after seeing hundreds of smaller coyote/bobcat scat piles along the trails, then an extra-large one shows up?  It's way obvious.  Haha.  Andy came with me this time to serve as my mt. lion guard and backpack carrier.  Sweet!

ear-shaped wild buckwheat grazed down to knee-high

Coyote, bobcat, and mt. lion scat weren't the only poo bits I found on that first trip. On the west side of the Park's impressive pig fence, yet still within Park property, are meadow muffins.  Lots of meadow muffins.  I predicted to Paul that any protruding buckwheat I might find would be grazed.  Apparently, the neighboring cattle are free to roam ever since BLM days.  Yep, almost all the stalks (turned out to be ear-shaped buckwheat) in a roughly 50x30' area had been chomped.  Interestingly, the nearby long-stemmed buckwheat, also in bloom, didn't appear to be touched, except for a solitary clump.  While we found my first evidence of deer scat on the west side (there are reportedly more deer on the east side), it was located on the other side of the fence and far enough away from this hill to not be a contender.  Don't know if this could be a potential land management issue, or not?  I've heard both pros and cons about cattle.  There are a couple stories of butterflies that disappeared after the land was closed for their protection, because their host plants needed the regular disturbance to grow.  So, who knows if this is good or bad?

edited 11/15/14 - I originally posted this as protruding buckwheat (Eriogonum nudum var. indictumJepson eFlora and eFloras of NACNPS CRPR 4.2), because that's what the official Pinnacles veg map calls it.  And, I know I have the exact location, thanks to GPS.  Unfortunately, there isn't a Park herbarium specimen for this location and no known photos.  I've been trying to convince myself that it's a match ever since writing this blog post and looking up all the embedded links.  After all, the folks who did the mapping probably know way more than me. Right?  Ugh, I've finally decided this ID is incorrect, even though I've never knowingly seen var. indictum in person before.  Yeah, the nerve of me!  It helped that I found inflated stems, exactly this shape, on very clear E. nudum var. auriculatum at Fort Ord today and confirmed by David Styer.  What convinced me that this is also var. auriculatum are the hefty white flower clusters, white and pink anthers and green sepal/tepal highlights that appear to be typical of var. auriculatum, specific shape of the inflated stems, and notable lack of silvery-sage woolly leaves that's evident in all the online var. indictum photos that I've found.  However, it's a bit late (November!) to be blooming for var. auriculatum, but I've rarely found reported bloom times to be reliable.  Who knows, maybe var. indictum was also there and I just didn't find it?  Or, maybe 10 years ago it was var. indictum (Paul recalls distinctly yellow flowers) at this location and for whatever reason it's changed?  Although, I find this scenario highly unlikely.  I've made additional minor corrections in the original blog post above.

acmon blue on naked buckwheat ~ 09/10/14 ~ Podere di Farfalla

I mentioned in a previous mating acmon post on seacliff buckwheat from mid-July about how host plant associations cannot be assumed.  I'm trying to do a better job at documenting the butterfly, the plant, and the activity.  Here I found them on another type of buckwheat (one that was not evident to me back in July).  I was able to get a series of mating photos that made for a surprisingly graphic gif.  Unfortunately, after succumbing to a fit of giggles, I decided other people may not appreciate my crass animal p0rn humor (or it might get stolen and put on a site I would be embarrassed to show my grandmother, if you know what I mean).  And so, it's not included on Nature ID.  However, it was eye-opening to see how butterfly sexy parts actually fit together.  I never took such a close look before.

This is the true money shot for me.  Laying an egg on an identified host plant.  Although, as I witnessed this spring, females sometimes get their host plants mixed up.  No kidding.  It's apparently how insects regularly adapt to using introduced plants.  It's evolution in action.  At the time, I was encouraged to find the egg of my unusual sighting.  Ha!  I tried, I really did.  It's very much like looking for a needle in a haystack.  Miniaturized.  What's not always obvious from photos is exactly how small all of this is.  I seriously doubt I'll be able to get a clear picture of something as tiny as an acmon egg out in the wild, on a cliff, in bright sun, and the ever-present wind.  With my relatively recent need for reading glasses, I couldn't even see what the egg here looked like after the female did her quick drop off.  I'm starting to view television nature shows in an entirely different light now and not in a good way.  Instead of oohing and awing over nature, I'm wondering how the heck they managed to film whatever it is that they did.  Seriously.  Eh, I like my easy crappy photos.  So, on to the plant...

Polygonaceae

While I already suspected which buckwheat this was, I used the plant list for Podere di Farfalla to narrow down the possibilities of buckwheats, from 256 spp./var. found in all of CA to just 6, plus 4 more from nearby Garland Ranch.  I looked at all the possibilities, and more, just to make sure it wasn't something I hadn't heard of before.

The official CNPS list for Garland Ranch shows another of the 14 var. of naked buckwheat (geez, there's a lot), sometimes called hairy flowered buckwheat or Fremont's wild buckwheat (E. nudum var. pubiflorum).  I took a close look at the few available photos online, and I think the leaves here look more like auriculatum than pubiflorum.  Leaf shape more determinate over level of fuzz on top?  It's a close call, and I could be wrong.  If anyone knows better, please tell me!

acmon blue on seacliff buckwheat ~ 07/17/14 ~ Podere di Farfalla

mating acmon (male left, browner female right) on seacliff buckwheat
mating Icaricia acmon (aka Plebejus acmon) on Eriogonum parvifolium (var. parvifolium)
Polygonaceae

Having both acmon blue sexes in the same photograph is very helpful, because I've had some difficulty distinguishing between them on their own, since lighting and wing angle can be so variable and deceptive.  Ya, I know, I've been told repeatedly, "Get a photograph of the topside (dorsal), then it's easy to tell them apart."  Ha!  As if it were that easy!  I'm thrilled whenever I can get any photograph at all that's not a total fuzzy blob.  Seriously.  And, after seeing numerous butterflies in a day, I never can remember if the topside of butterfly #34 was blue or brown while it flew away.  Maybe other people have an easier time of it?  This is only my second photo of mating butterflies that I've managed to get all year.  The first were Edith's checkerspots back in May at Pinnacles.  As with the Melissa blues, the female acmon blues have a browner ground color on the underside (ventral).

I'm noting the plant they're perched on while they do their thing, but that may not mean much.  While I do have other photographs of worn female acmons nectaring on seacliff buckwheat, I don't have any photographs of egg-laying on this plant.  It cannot be assumed seacliff buckwheat is the larval host plant of these acmons.  I didn't notice any other buckwheats or lotuses in bloom in the area, which also may not mean much.  In any case, I thought this would be a good time to showcase this lovely local buckwheat...

ps 11/21/14 - Jim Reveal confirmed this ID, and if he recognized varieties, he'd call this var. parvifolium.

coast buckwheat ~ 05/18/14 ~ San Bruno Mt.

Polygonaceae
(fuzzy and not fuzzy)

 coast buckwheat leaves
(fuzzy and not fuzzy)

coast buckwheat in bloom
(fuzzy and not fuzzy)

Polygonaceae
(fuzzy and not fuzzy)

I'm on a mission to learn the regional buckwheats as they bloom this year, because it's much easier to locate them when they're in full blooming glory.  Calflora currently lists 256 spp./var. of Eriogonum.  That's a lot of buckwheat, and it's all quite confusing.  Fortunately, I'm focusing on the dozen or so found regionally from the central CA coastal area, inland to Pinnacles.  So when the opportunity came up to visit San Bruno Mountain with Santa Clara Valley CNPS guru Ken Himes, I was ready to get my buckwheat IDs sorted.  Turns out, the mountain in all its uniqueness has only one sp. of buckwheat, E. latifolium, locally known as coast buckwheat, and elsewhere described as seaside buckwheat.  I found plenty of variation, from pink to white blooms, perfectly round to flatted pom-poms, fuzzy to green leaves, short stalk stature to reaching for my knees.  I kept asking Ken, "Are you sure this is still coast buckwheat?"  He laughed at first, but then I think he tired of my repeated questions.  I still suspect there's some naked buckwheat (E. nudum) in the above with the flattened flower heads and greener, fuzzless top, larger leaves.  In any case, I'm now familiar with coast buckwheat, and I hope I can recognize it even when it's not blooming.  I found the low-growing, wavy-edged leaf shape with fuzzy underside to be recognizable, but not entirely distinguishable.  It's a perennial herb.  So, does that mean it dies after 2 years?  Yes, I'm seriously asking.

buckwheat ~ 07/14/11 ~ Garland Ranch

buckwheat
Eriogonum sp.
Polygonaceae 


I've resigned myself to the fact that some buckwheats are simply too difficult for me to ID to sp., let alone ssp. I'm guessing there are two different Eriogonum spp. in this post. Instead of pulling my hair out and spending way too much time on a single blog entry, I'm perfectly okay to post these buckwheats without a positive ID. I'll need to remember to try to take pictures of the leaves, which can often be a challenging task when they're growing in a tangle among other plants. The sunny yellow flowers shown above are common madia.


buckwheat
Eriogonum sp.
Polygonaceae

The yellow blooms above are, I believe, deerweed. I'm starting to suspect that other plants found growing right next to an unknown can help ID the unknown. I often use the Monterey Bay Chapter of the CNPS local plant lists to help me narrow down from hundreds of species (at least 268 Eriogonum sp./ssp. in CA alone) to just a handful. Although, I know based on my own findings and flowers listed in Wildflowers of Garland Ranch - a field guide by Michael Mitchell and Rod M. Yeager that the CNPS list is not nearly complete. For my future reference, here's a combined list of what has been documented at Garland Ranch from CNPS and the book (* denotes my guesses for the above):

(CalPhotos) --- (Calflora) --- (Jepson Interchange - older version)
elegant buckwheat --- E. elegans --- uncommon, sand or gravel
* long-stemmed buckwheat --- E. elongatum var. elongatum --- common, dry places
* coastal California buckwheat --- E. fasciculatum var. fasciculatum --- coastal scrub, often on bluffs
St. Catherine's lace --- E. giganteum --- uncommon, dry slopes, ridges
slender woolly buckwheat --- E. gracile var. gracile --- sand
* naked buckwheat --- E. nudum var. auriculatum (book) --- common, rocks or gravel
hairy flowered buckwheat --- E. nudum var. pubiflorum (CNPS) --- common, dry flats, slopes
seacliff (dune) buckwheat --- E. parvifolium --- dunes, seabluffs

ps 09/13/14 - Both the CNPS list and the Wildflowers of Garland Ranch were updated shortly after I originally wrote this post.  I've made minor var. corrections above for coastal CA buckwheat and slender woolly buckwheat.  I'm not making any guesses as to spp. from these photos, because I've since learned to take better pictures of the leaves, which for me is extraordinarily helpful.

For my own record keeping purposes, Podere di Farfalla is in the general area as Garland Ranch, and its plant list is as follows:
elegant buckwheat --- E. elegans
long-stemmed buckwheat --- E. elongatum var. elongatum
Mojave Desert California buckwheat --- E. fasciculatum var. polifolium --- dry slopes, washes
Pinnacles buckwheat --- E. nortonii --- sand
naked buckwheat --- E. nudum var. auriculatum
seacliff buckwheat --- E. parvifolium

pss 11/19/14 - I now believe the first set of photos above are seacliff buckwheat (E. parvifolium), and the second set of photos are likely (not absolutely positive) ear-shaped wild buckwheat (E. nudum var. aruriculatum).  Newer seacliff buckwheat and naked buckwheat posts have more detail.

CA buckwheat ~ 06/09/11 ~ Pinnacles



California buckwheat
Eriogonum fasciculatum var. foliolosum
Polygonaceae

updated 09/10/14 - There are 4 var. of Eriogonum fasciculatum, and only 2 are reported for Pinnacles.  I'm pretty confident now that this is the greener foliolosum and not the fuzzy, grayer polifolium.  The original post is below:

Good golly! This is my best guess for buckwheat. At least I'm starting to familiarize myself with a few of the 268 Eriogonum species/varieties found in California. It's no wonder so many animals feed on buckwheats, including caterpillars of the bernardino dotted blue shown previous to this post. There's also a fun, mysterious arthropod peeking around the flowers in the second pic above.

The following Eriogonum names were taken from the 2005 Pinnacles plant list and the embedded links are for my future reference:

(CalPhotos) --- (Calflora) --- (Jepson)
angle-stemmed buckwheat --- E. angulosum --- chaparral
Coville's buckwheat --- E. covilleanum --- rock & scree
elegant buckwheat --- E. elegans --- riparian
long-stemmed buckwheat --- E. elongatum --- rock & scree
California buckwheat --- E. fasciculatum var. foliolosum --- chaparral
California buckwheat --- E. fasciculatum var. polifolium --- chaparral
graceful buckwheat --- E. gracile var. gracile --- chaparral
Pinnacles buckwheat --- E. nortonii --- rock & scree
nude buckwheat --- E. nudum var. auriculatum --- rock & scree
nude buckwheat --- E. nudum var. indictum --- chaparral
virgate buckwheat --- E. roseum --- rock & scree
rock buckwheat --- E. saxatile --- rock & scree
Wright's buckwheat --- E. wrightii var. subscaposum --- rock & scree
