Descripción

Poison Canyon stickseed, Hackelia brevicula, California, White Mountains, Cottonwood Basin, Poison Creek, Fishlake Valley drainage, elevation 2960 m (9710 ft).

This rare species is endemic to the White Mountains, almost entirely in Mono County, California, but getting into the northeast edge of Inyo County, California, and possibly the west edge of Esmeralda County, Nevada. Within this very limited geographic range, it is further confined to a zone mainly of higher montane and subalpine elevations between 2650 and 3150 meters (8700-10300 feet). Within this zone, however, it is locally common in mountain sagebrush, aspen woodland, riparian edges, and other habitats. Quite frankly it's hard to understand how it can be so rare, with its barbed, easily detached seeds that I pick out of my clothing whenever I hike through the area. (Maybe I should stop picking them out? ;-).

The common name, Poison Canyon stickseed, comes from the canyon where this image was taken. The type specimen was collected here (and later named) by Willis Lynn Jepson in 1917.

Descripción

mountain bitterbrush, Purshia tridentata, unnamed high-elevation variant, White Mountains, elevation 3215 m (10545 ft).

This bitterbrush form is found at higher elevations in (at least) the southwestern portion of the species range, has often been called Purshia glandulosa, and has been a source of confusion between the two species. This form seems to intergrade only with Purshia tridentata, with which it shares flat and relatively thin (though mostly smaller) primary leaves with only narrowly inrolled margins. It gets confused with P. glandulosa because of its tendency toward primary leaves glabrous above with margins often ciliate-glandular, and glands more frequent on the hypanthia and peduncles, as seen clearly on this plant.

Purshia glandulosa, on the other hand, appears to be a completely distinct species centered around the Mojave Desert, and characterized by primary leaves strongly thickened and inrolled most of their width, and with upper leaf surfaces always glabrous and glutinous. It appears to flower later where it grows in proximity to P. tridentata, and intermediates have not been found so far.

Field observations are ongoing to determine whether mountain bitterbrush warrants a formal scientific name as a variety of Purshia tridentata.

silver arnica, Arnica chamissonis var. incana, California, White Mountains, McAfee Meadow, McAfee Creek, Fishlake Valley drainage, elevation 3568 m (11705 ft).

The White Mountains representatives of this species seem a little different from populations elsewhere, being uniformly shorter with fewer pairs of leaves, and sometimes being mistaken for Arnica parryi. The best fit appears to be a variant of var. incana, which otherwise occurs in wet places mainly along the Sierra Nevada and Cascade axis, eastward irregularly into the Great Basin. Like so many other species, it reaches its highest elevation limit here in the White Mountains, but also extends well down through the subalpine zone in appropriate habitats.

Descripción

Staminate and pistillate shrubs are particularly evident this time of year with each catkin type bearing flowers at full anthesis, or nearly so. The glabrous reddish twigs and leaves equally green above and below are diagnostic of Booth's willow. This site lies in the North Bowl of the Bridger Bowl ski area, Gallatin Range, Gallatin County, Montana.

Booth's willow is a native shrub to 5 m tall and common along streams and lakes and generally in wetland areas from low to high elevations in western and south-central Montana. A shrub with a rounded canopy, twigs that are glabrous and yellowish, and leaves equally green on both surfaces are diagnostic of this species. Booth's willow is similar to yellow willow, Salix eriocephala (Salix lutea), except that the leaves are equally green on both surfaces in Booth's willow whereas the leaves are distinctly lighter green (glaucous) on the lower surface of the leaves of yellow willow.

Abundant in sandy flats of Bishop Pass area. Fruit hairs don't seem to match with subumbellata, but most other characters do. My best guess, and I can't fit it in any other Draba box. Comments and alternative IDs welcome! Note: located and photographed this species in an unsuccessful attempt to relocate a historical Draba sierrae record from this same location.

Apparently gathering in this position to sleep for the evening. Noted in this position on several grass inflorescences. From a distance, it looked like the bees were a fungus growing on the grass inflorescence.

bog stitchwort, Minuartia stricta, California, White Mountains, McAfee Meadow, McAfee Creek, Fishlake Valley drainage, elevation 3566 m (11700 ft).

This mainly circum-arctic species has two isolated alpine outliers farther south in North America, one in Colorado, and one here in California, in the high alpine of the Sierra Nevada and the White Mountains. It is a very tiny and easily overlooked member of the wetland flora in these places.

Also visible in this image are leaves of White Mountains mousetails (Ivesia lycopodioides scandularis) and a fruit of slender whitlowcress (Draba albertina).
