Descripción

Nevada gilia, Gilia brecciarum subsp. brecciarum, Nevada, White Mountains, Sugarloaf, Pinchot Creek - Columbus Salt Marsh watershed, elevation 2664 m (8740 ft).

This relatively distinctive gilia is distinguished by its combination of widely divergent branches ending in crowded groups of few small flowers that are sessile or short-stalked, densely glandular calyces and branches, and middle leaves clasping the stem at bases. It is common in its range centered in the Great Basin of Nevada and adjacent edges, and extending southwest along the west edge of the Mojave Desert and adjacent mountains in California. In the Great Basin, like here, it is often found on clay soils in the valleys and lower mountains. As is often the case in the White Mountains, it seems to reach its upper elevation limit here.

little bitterroot, Lewisia rediviva var. minor, Nevada, White Mountains, Sugarloaf, Pinchot Creek - Columbus Salt Marsh watershed, elevation 2665 m (8745 ft).

This species is iconic to the mountains and steppes of western North America, and was first named and described from specimens collect during the Lewis and Clark expedition of 1806. It is the state flower of Montana, and the vernacular "bitterroot" ended up in the names of several places and features in the region. The Latin name "rediviva" refers to the plant's ability to revive after the thick roots appear to be dry and dead. The roots before flowering time were gathered as an important food source by indigenous peoples.

The variant here called little bitterroot is found in the southwestern part of the species' range, mainly in Nevada and California. It is characterized by fewer and smaller flower parts, and leaf blades cylindric or strongly rolled. The leaves wither and detach early, and have already done so on these plants.

cow cabbage, Asclepias cryptoceras, Nevada, White Mountains, Sugarloaf, Pinchot Creek - Columbus Salt Marsh drainage, elevation 2696 m (8845 ft).

If I had to pick a favorite milkweed species, this might have to be the one. Low growing but with exceptionally large and showy flowers, this species is fairly widespread at middle elevations in the interior western United States, often on harsh and relatively barren soils, such as the alkaline volcanic clays here. These plants of the western Great Basin and Columbia Plateau are sometimes separated from the more eastern plants as var. davisii.

flowery bedstraw, Galium multiflorum, male plant, Nevada, White Mountains, Sugarloaf, Pinchot Creek - Columbus Salt Marsh watershed, elevation 2701 m (8860 ft).

In its narrow sense, this species is still common at middle elevations in rocky sagebrush habitats of the Great Basin and northern Mojave Desert of the western United States. A number of other species now considered distinct were once lumped under a much broader concept of this name, extending its range farther east and north. As narrowly defined, Galium multiflorum is distinguished by having separate male and female plants (dioecious), along with a subshrubby habit, spreading hairs, long-hairy fruits, and abruptly short-pointed rounded leaves in unequal pairs at each node and that arch downward in age.

reflexed rockcress, Boechera retrofracta, Nevada, White Mountains, Sugarloaf, Pinchot Creek - Columbus Salt Marsh watershed, elevation 2681 m (8795 ft).

This relatively distinctive rockcress is widespread and common in many habitats and elevations up to subalpine in western North America into eastern Canada.

woollypod, Astragalus purshii var. tinctus, Nevada, White Mountains, Sugarloaf, Pinchot Creek - Columbus Salt Marsh watershed, elevation 2667 m (8750 ft).

This variety is common and widespread in dry habitats at middle elevations throughout much of California and the western half of the Great Basin. Sometimes also known as rabbitsfoot milkvetch, it has brilliant purple flowers when found early enough in the season.

Two other species in the region with similar densely hairy pods are Astragalus newberry (somewhat larger flowers) and Astragalus coccineus (even larger bright scarlet flowers), both of which also differ by having straight appressed hairs on the leaves (versus loose and curly in A. purshii), and strictly leafless stems above the base (versus shortly leafy in A. purshii).

mountain dandelion, Agoseris parviflora, Nevada, White Mountains, Sugarloaf, Pinchot Creek - Columbus Salt Marsh watershed, elevation 2664 m (8740 ft).

This is a common and widespread species in the western United States, at middle elevations in dry to somewhat moist habitats.

Johnson linanthus, Linanthus bigelovii subsp. johnsonii, California, White Mountains, Black Mountain, Owens Valley watershed, elevation 1417 m (4650 ft).

The subspecies johnsonii was named in 2015 to account for the non-glandular plants in the western part of the species range, including here in the White Mountains. Turns out that typical subspecies bigelovii from Arizona is sparsely stalked glandular on the upper stems.
