Psathyrotes, Psathyrotopsis, and Trichoptilium (Oh, My!)

Recently I found myself looking closely at keys, descriptions, and photos of Psathyrotes annua (Annual turtleback) and P. ramosissima (“regular” Turtleback)—both rayless members of the Sunflower family, Asteraceae—to clear up some lingering uncertainty over how to distinguish the two. Then one taxon led to another and it became a larger project.

Psatyrotes annua is familiar to many who have wandered the perimeter of Mono Lake. It thrives in the sparsely vegetated sands and gravelly pumice of Mono’s prehistoric and post-1945 receding shorelines. It’s often misidentified as P. ramosissima, which so far, has probably not been found in the Mono Basin, but is common in the Mojave, Colorado, and western Sonoran Deserts. These two can be distinguished as follows:

  • Leaf blades generally clearly divided by deeply-set, anastomosing (cross-connecting) veins into irregular, ovate to polygonal areas (suggesting the segmented “scutes” of a turtle’s carapace); outer phyllaries ± wide, spatulate to obovate, widely spreading to reflexed; florets 21–26 (16–32) per head; pappus of 120–140 bristles in 3–4 series …… Psathyrotes ramosissima
  • Leaf blades generally weakly or not at all divided by veins into scute-like areas; outer phyllaries ± narrow, mostly lance-linear, ± erect to spreading; florets 13–16 (10–20) per head; pappus of 35–50 bristles in one series …… Psathyrotes annua

Exploring this small genus further, one finds there are currently three species in Psathyrotes, another close relative formerly in Psathyrotes now banished to Trichoptilium—a monotypic (one species) genus—and three more close relatives housed in Psathyrotopsis, a newer genus carved out of Psathyrotes.

Apparently no single key has been crafted that includes all 7 species of Psathyrotes, Trichoptilium, and Psathyrotopsis. The Jepson eFlora includes two Psathyrotes and the Trichoptilium. The Flora of North America (FNA) includes all three Psathyrotes, the Trichoptilium and one species of Psathyrotopsis, but not the other two, which appear to be narrow endemics in southern Coahuila, Mexico. Both Jepson and FNA make you work through ponderous keys for the entire sunflower family to distinguish these three genera. A paper on “Taxonomy of Psathyrotes” (Strother and Pilz 1975) includes a key to all of the taxa included in FNA, but not the third Psathyrotopsis, because it was described later (Turner 1993).

So, why not write a straightforward key that includes all seven taxa? Not so simple, it turns out, because existing keys don’t all use the same set of characters, and that newest species endemic to southern Coahuila (Psathyrotopsis hintoniorum) has never been included in a key with its relatives—and the paper describing it refers the reader to the formal description in Latin to figure out what distinguishes it from Psathyrotopsis purpusii. Thank goodness for Google Translate!

Below is an image of my key. (The very limited text formatting abilities in this WordPress blog don’t lend themselves to an indented key longer than 1 or 2 couplets.) The key is adapted from Baldwin 2012, Strother 2006a, Strother 2006b, Strother and Pilz 1975, and Turner 1973 (citations below). It has been modified from the originals by adding species, changing some terminology, rearranging some couplets, and adding some character states.

Here are photos of the rest of the species in Psathyrotes, Psathyrotopsis, and Trichoptilium (thank you to the iNaturalist contributors who allow their images to be used non-commercially!)

A History of Plant Collecting in the Bodie Hills

Back in March 2023, I did a presentation for the Nevada Native Plant Society on plants of the Bodie Hills. One small part of that presentation was a review of the history of botanical collecting, and more recently, iNaturalist observations of plants, in the Bodie Hills. It was an interesting topic to research, so what follows is an expanded summary of my findings, along with some charts and maps.

Collections of Plant Specimens in Herbaria

I compiled a list of all plant collections in the Bodie Hills using search tools of the Consortium of California Herbaria (CCH). Their CCH2 portal serves data from all specimens (vascular and nonvascular, in California and beyond) housed in all 55 CCH member herbaria. These data portals allow anyone to search digitized records of herbarium specimens in a variety of ways. Because about a third of the Bodie Hills is in Nevada, and CCH2 data are not restricted to California, I used the CCH2 portal to find and download records of 4,268 plant collections throughout the Bodie Hills from 1866 through 2021.

Here, then, is a timeline (below), summarizing the number of herbarium specimens collected over various periods of time. Below each of the green bars are the names of botanists who collected the most during those periods.

The timeline above may appear too small to read on your screen, so below I’ve divided the same thing into three larger sections.

The earliest collections listed were of Ericameria nauseosa and Sphaeralcea ambigua by Henry Bolander in 1866. The locations were recorded as simply “near Bridgeport,” so these may not have been exactly in the Bodie Hills. Bolander was an energetic collector while he was California State Botanist, 1864–1873 (and later, State Superintendent of Public Instruction, then San Francisco Superintendent of Schools).

Thirty-two years later, in 1898, Joseph Congdon collected Atriplex canescens, Opuntia polyacantha, and probably also Artemisia nova along a what he called the “Mono to Bodie (Desert Road)” and a “side-road between Goat Ranch and Bridgeport.” I believe these were along what is now Coyote Springs Road in Bridgeport Canyon. This was for many years the main route from Mono Basin to Bridgeport, before roads were established over Conway Summit. Congdon was a lawyer who lived in Mariposa, 1882–1905, and contributed significantly to early botanical exploration, particularly in the Yosemite region.

Harvey Monroe Hall made at least 7 collections in the hills between Mono Basin and Bridgeport in 1918, 1921, and 1925. Hall at that time worked at the Carnegie Institution Division of Plant Sciences at Stanford University; throughout his life he collected over 200,000 specimens. Philip A. Munz made a few collections in the same area in 1928. Munz was then a young professor of botany at Pomona College. Decades later, Munz and David Keck authored A California Flora (UC Press 1959), which became a standard reference for identifying California plants for more than 30 years.

Botanical collecting took a leap forward and across the state line in 1929, when “Mrs. John D. Wright” collected at least 29 specimens around Aurora. Ysabel Galban Wright, born in Cuba in 1885, married John Dutton Wright (founder of the Wright Oral School for the Deaf in New York City, where Helen Keller was an early student) in 1912. The couple relocated to Santa Barbara about 1919, where Ysabel became an avid gardener with a special interest in cacti and California native plants. She visited Aurora during a botanical collecting trip that also included Mono and Tuolumne counties in 1929.

During the 1930s several botanists collected in the area, notably Carl B. Wolf (Botanist at Rancho Santa Ana Botanic Garden 1930–1945), and G. A. Graham and T. M. Hendrix (both collecting and documenting vegetation in 1937 for what was then Mono National Forest).

In the 1940s, additional names familiar to California botanists appear in the list, including Annie Alexander & Louise Kellogg, Ira Wiggins & Reed Rollins, Roxanna Ferris & Laura Lorraine, and again, Philip Munz (who took a particular interest in the flora at Travertine Hot Springs). It was in the summer of 1945 that Wiggins & Rollins collected type specimens of both Streptanthus oliganthus (Masonic Mountain jewelflower) and Boechera bodiensis (Bodie Hills rock-cress). Also in the summer of ’45, Alexander & Kellogg collected type specimens of Cusickiella quadricostata (Bodie Hills Cusickiella) and Phacelia monoensis (Mono County Phacelia). Others collecting here during the ’40s included C. Leo Hitchcock, Robert F. Hoover, Beecher Crampton, and Malcolm A. Nobs & S. Galen Smith.

During the 1950s, Philip Munz visited the Chemung Mine area. Thomas C. Fuller (Plant Taxonomist for the California Department of Food and Agriculture) collected along the west side of the Bodie Hills. Clare B. Hardham collected along the Bodie-Masonic Road near Potato Peak.

In the 1960s, Jack Reveal (forest ranger) and his son James L. Reveal (renowned Eriogonum taxonomist and professor) collected in the area. Clare Hardham again visited the Rough Creek/Potato Peak area, and Masonic Mountain. Darley F. Howe collected near Bodie.

During the 1970s, Dean Taylor collected extensively throughout the Mono Basin and surrounding areas. Other collectors included Dennis Breedlove, Glenn Clifton, Ken Genz, and George K. Helmkamp (chemistry professor at UC Riverside). A spike in collecting occurred in 1979, because that’s when I arrived on the scene, collecting for my MA thesis (a local flora of the Bodie Hills) at Humboldt State University. I continued collecting for that project in 1980-81.

During the early 1980s, Matt Lavin, then a graduate student at UNR, collected extensively in the northern Bodie Hills for his floristic study of the upper Walker River watershed. Others active in the ’80s included Arnold (Jerry) Tiehm (Herbarium Curator at University of Nevada Reno) and Jan Nachlinger (plant ecologist), Dennis Breedlove, Glenn Clifton, Mary DeDecker, Barbara Ertter, and Hugh Mozingo (author of Shrubs of the Great Basin: A Natural History).

During the 1990s and 2000s there was less collecting in the Bodie Hills, though Tom Schewich and others were quite active in and around the Mono Basin.

In the 2010s Ann Howald started collecting intensively throughout Mono County, including the Bodie Hills. Jerry Tiehm and Jan Nachlinger made more visits to the Nevada side of the range. In recent years, Ann Howald (preparing a Flora of Mono County) and James André (of the Granite Mountains Desert Research Center) have been the most active collectors in the Bodie Hills.

In summary, my search produced a list of about 4,268 specimens from the Bodie Hills, collected from 1866 to 2021. I say “about”, because a few were probably collected outside the area but their locations were mis-mapped or misinterpreted as being within the Bodie Hills (erring on the side of too many specimens). On the other hand, some specimens probably exist that have not been digitized and georeferenced, or reside in herbaria that are outside the scope of CCH2 (erring on the side of too few specimens). Also, the search area boundary is a bit arbitrary in some areas and can be adjusted to include more or fewer collections.

Much more interesting than the exact number, though, is to see the names of people who have collected there, if only briefly, over the decades. Many of them became well known for their contributions to western American botany.

Observations of Plants on iNaturalist

Several years ago an ambitious citizen science project called iNaturalist came on the scene, providing me and many others with a different way to document biodiversity—by uploading photographs of identifiable species, along with location, date/time, and sometimes other metadata for each observation. There are many caveats to consider in assessing the quality and value of any particular set of iNaturalist data, but on the whole, it’s an effective way for anyone from casual, curious non-specialists to seasoned professional biologists to quickly share observations, get feedback, and learn from what others have posted. Physical specimens enable types of research that cannot be done from photographs alone, but I think iNaturalist provides a useful compliment to traditional herbarium-based collections.

The timeline below shows plant observations in the Bodie Hills posted to iNaturalist, by year, from 2012 through 2022. In the background, for comparison, are the numbers of herbarium specimens from the charts above. The number of observations is growing rapidly. Many of these observations are mine, but certainly not all, and some very noteworthy observations (documenting species neither collected nor observed previously in the Bodie Hills) have been posted by others.

You can generate an updated search in iNaturalist, and revise the search criteria if you wish, HERE.

Locations of Collections and Observations

The maps below show you that both collections and observations have been concentrated along (1) roads that provide relatively easy access and (2) other popular areas to visit in the Bodie Hills.

Little or no collecting or observing has occurred in some other areas. These are among the more remote and difficult-to-access corners of the Bodie Hills. Such areas include:
• Mount Hicks and Spring Peak
• Aurora Crater
• Bald Peak
• Southeast perimeter of the Bodie Hills
• Atastra Creek and the middle reaches of Rough Creek
• Masonic Gulch north of Masonic Lower Town
• Aspen groves south of upper Aurora Canyon
• Big Alkali

Treks into these remote areas could be rewarded with interesting discoveries!

Mystery Plants in the Bodie Hills

I need your help—those of you who live somewhat close to the Bodie Hills. Three plants have yet to be identified there because they have not been seen up close, photographed clearly, or observed under the right conditions for identification. Since my home is a nearly 5-hour drive from their locations, I don’t know when I might be in the right places at the right times to identify these plants. So, I invite anyone who is interested to do a bit of “citizen science” botanical field work and post the observations on iNaturalist. Details follow.

Mystery Plant #1: An Aphyllon Near Aurora

This plant has been observed twice, in June 2021 and April 2022 at the base of a road cut along the road to Aurora (Mineral County, Nevada), about 0.85 mile south of the intersection with the road through Del Monte Canyon to Bodie (elevation about 6,400 feet). Both times the plants were well past flowering, dried out and crumbling to the point where critical features for identifying the species were no longer present.

When might these plants be in fresh, identifiable condition? Similar plants have been observed in Adobe Valley southeast of Mono Lake (Mono County, CA)(elevation about 6,500 feet). Plants in that area appear to have been in good condition during July. The plants in the photos above had probably flowered during the previous summer.

This plant is clearly in the genus Aphyllon (Broomrapes) of Orobanchaceae (Broomrape family). They are parasites. Lacking chlorophyll, they derive sugars and other nutrients needed for growth from the root systems of nearby shrubs, often sagebrush or rabbitbrush. The inflorescence emerges directly from the ground. It tends to be mostly purplish, yellowish, or brownish in color, with the corollas various combinations of purple, pink, yellow, and white. A taxonomic note: All Broomrapes in North America (about 17 species) were formerly in Orobanche, before that genus was split mid-Atlantic, with all the New World Broomrapes placed in genus Aphyllon and all Old World species remaining in Orobanche (see PhytoKeys 75: 107–118 for an explanation).

Our mystery plant also clearly has an elongate above-ground stem that bears flowers on short pedicels, as in Aphyllon parishii and several other species. In some other species the flowers emerge on much longer pedicels from a very short, below-ground stem—which is the case in two other species of Aphyllon found in the Bodie Hills: A. corymbosum and A. fasciculatum.

The Aphyllon observations in Adobe Valley have been difficult to identify and it’s been speculated (here and here) that an undescribed taxon may be lurking in that area. Could the Aphyllon near Aurora fit into this potentially new taxon also? Photographs showing details of flowers, bracts, and stem are needed.


Mystery Plant #2: A Silene Near Cow Camp Road

This plant is definitely in Caryophyllaceae (Pink family); I think it’s a Silene (because of the notched petals), maybe Silene nuda (Sticky catchfly). But in these photos that came to me by way of the Eastern Sierra Land Trust, from someone wanting to identify it, the image resolution is just a bit too low for a confident identification, so it needs to be revisited in the field. This was seen (in early August, 2019) in the central Bodie Hills, roughly mid-way between Cow Camp Road and Rough Creek, a little north of “Halfway Camp”, elevation about 7650 feet.

Another tall, perennial Silene reported to occur in the eastern Sierra is S. verecunda (San Francisco campion). In Silene nuda, the pedicel and calyx are glandular-puberulent to glandular-hairy. In Silene verecunda, the pedicel and calyx are puberulent (short-hairy), but not glandular. Photos of the plants should therefore include close-ups of the flower, calyx, and pedicel. Clear views of the basal and cauline leaves (showing shape, hairiness, and relative size) would be helpful as well.

The nearest collection of Silene nuda is in Douglas County near Topaz Lake. The species occurs in the northern Sierra Nevada—mostly north of Tahoe—to south-central and southeast Oregon, southern Idaho and across northern and central Nevada. If confirmed here, the Bodie Hills would be the southwestern-most known occurrence of Silene nuda.

Mystery Plant #3. A Pine Near Millersville

High on a remote mountain slope 1.2 miles north-northwest of Potato Peak, above the head of a steep gully at 9,540 feet, and surrounded by thickets of mountain-mahogany, is a small stand of pines. But which one? I think they’re most likely Limber pines (Pinus flexilis), because that’s what occurs at a similar elevation on the north slope of Bodie Mountain, but Lodgepole pines (Pinus contorta subsp. murrayana) occur in scattered, mostly small stands in the central Bodie Hills too. A much closer look at these pines is needed, ideally documenting their overall appearance, the number of needles per fascicle, and the size and appearance of the cones.

Viewed from far down in Aurora Canyon, the details needed for a confident identification are not visible. This stand of pines is a little north of the site of Millersville (topic of an earlier post).
