The totally rare blue tassel fern. This species is at the top of the plant collectors list so I have not indicated the location. It is in the Cairns region.
Growing with Nahuatlea hypoleuca, Euploca torreyi, Liatris punctata, Stenaria nigricans, on caliche. Possible volcanic tuff from Catahoula Formation present as well. Leaves glaucous and hirsute and lateral branches tightly congested. Probably one of the rarest plants in Texas, known only from two sites.
clubleaf monolepis, Neomonolepis spathulata, California, Mono County, White Mountains, North Fork Crooked Creek, Deep Springs Valley watershed, elevation 3101 m (10175 ft).
Only two plants located on exposed carbonate soils along highway.
Voucher SCMV-OCC. ~100 plants in flower and fruit. Growing in a rocky opening on a slight east-facing slope codominated by Eriogonum wrightii var. subscaposum and Chrysothamnus viscidiflorus.
With Christie Blakley, whose grandfather Jim discovered this obscure and highly range restricted species in 1963.
New occurrence, just 5 miles from California.
Note the defining reflexed hairs at tips of calyx lobes.
In the thicker mostly shaded siliceous shale beds, edges of the oak woodlands, Monterey Shale formation endemic. Growing here where few other plants are growing as the shale chunks were large.
Characterized by white hairs on inner calyces, and growth on siliceous shale.

Jalca de Coipin, the type locality for this very rare endemic of high elevations in the the Andes Mountains of north-central Peru.
Pine Nut Mountains mousetails, Ivesia pityocharis, Nevada, Douglas County, Carson Valley watershed, elevation 2335 m (7660 ft).
Libocedrus chevalieri est un arbuste endémique de Nouvelle-Calédonie, de la famille des Cupressaceae.
Cette espèce est uniquement présente dans le sud de la Grande Terre sur les massifs du Kouakoué et du Humboldt, dans le maquis ligno-herbacé altimontain.
Observed and photographed by Fabian Gonzalez. This appears to be an un-described species. Hairs on petals do not match those of Viola atropurpurea, which very rarely has yellow flowers. The plant seems more similar in the shape of the rosettes and hairs on petals to Viola skottsbergiana, a plant with white petals and similar markings on the lower petals.

Seems to match this observation found a short distance to the south on Nevado de Longaví.

In 10th photo, Nevado de Longaví, can be seen in the distance.
Growing at an altitude of 2980 m.
The population consists of thousands of plants that are all consistently yellow or yellow-orange colored.
Other yellow flowered species in the Section Sempervivum include V. auricolor, which has smaller, more loosely arranged rosettes, and larger flowers compared to the size of the rosettes. It grows far to the south of this location.
Viola coronifera has yellow flowers that are arranged at a different angle on the rosettes.

Parece que es una especie desconocida. Los pelos de los pétalos son diferentes de los de Viola atropurpurea. Es mas parecido en la forma de las rosetas y en los pelos de los pétalos a Viola skottsbergiana, que tiene pétalos blancos con manchas parecidas.

Parece bastante parecido a esa observación del Nevado de Longaví, que está unos 30 kilometros al sur:
https://www.inaturalist.org/observations/77911856
Crece a una altura de 2980 msnm.
Otras violas de la sección Sempervivum con flores amarillas incluye Viola auricolor, que tiene rosetas mas pequeñas, con hojas no tan apretadas, y flores mas grandes en comparación al tamaño de las rosetas. Esa especie ocurre muy al sur.
Viola coronifera, que ocurre mas cerca al sur, tiene flores amarillas que salen en angulo diferente en las rosetas en comparación a esa especie.
Only known population in the United States. Map location is approximate. Permission must be obtained to access this private land.
This observation, made 31 years ago, was the only fairly recent record of this species in the U.S. It is mostly found in the pine-oak zone in the Sierra Madre Occidental and adjacent parts of Mexico. The previous last record in the U.S. was in 1907, with a collection obtained by the noted AZ botanist, J.W. Blumer. This location and Blumer's collection is also the type locality of the synonymous name, C. cruneta Standl. As far as I know, this species has not been recorded in the US since my 1992 observation. I have not revisited this location since that time. The precise location is obscured because the site is on private land, and I don't wish to bring harm to either the species or to folks who might be inclined to look for it, if you take my meaning. The precise location was transmitted to rare plant agencies and herbaria at both the state and federal level in 1992. The status of this population is presently unknown. But it is definitely worth searching similar areas in the western foothills of the Chiricahua Mountains, especially on public lands, for additional populations. This sighting is further documented in a Note in Madroño 40(3): 176-177, 1993.
Note the two color morphs visible in the final photo.

I'm pretty sure this is P. moriahensis - got there a little too late to catch it in flower
Collection #2289
Moist sandy soil oak woodland. Very near type locality of G. tenella.
I think these are the first photos of this plant alive.

Some stragglers.
Opening in chaparral, sandstone. Rare - only two distinct populations observed.
Neat plant - hard packed disturbed soils, juniper woodland.

A number of iNaturalist observations have been posted of this undescribed taxon from Kelso Dunes and Soda Lake Basin sands, past collectors have placed under M. transmontana. Tasha La Doux and I in the process of compiling background information and conducting morphological and genetic research leading up to the publishing of this as a new taxon.
Blooming out of season
Undescribed species
Almost certain this is a new, undescribed species. Not even sure what genus it could be in. Possibly a new Xylorhiza. Fairly abundant on steep carbonate slope with very shallow soil. Death Valley. Anyone know how to get a permit from the National Park to collect a specimen?
Ate a deer in the bed of my truck
Very special find! Not common at all around here. Only found 2 individual plants within this canyon. The swallowtail butterflies were loving it.
Many thanks to @reodell for location. Most plants not yet blooming. last photo with Navarretia mitracarpa.
Last photo with C. clevelandii.
Observed in April 2001, in a serpentine grassland near the Presidio's "Log Cabin" special events building. Emerged during a period after irrigation around the Log Cabin facility had been turned off for several years. Population crashed after irrigation was resumed. This species is now presumed extirpated from the City and County of San Francisco.
