coastal lipfern, Myriopteris intertexta, California, White Mountains, Falls Canyon, Hammil Valley - Owens Valley watershed, elevation 2024 m (6640 ft).

This species is found in moist and/or sheltered rock crevices up to middle elevations in the mountains in northern California and adjacent Oregon and Nevada, with a disjunct location in Utah. It is considered to be of ancient hybrid origin between M. covillei and M. gracillima, and is distinguished from both by the combination of dark green upper leaf surfaces, and lower surfaces with narrowly lanceolate scales not completely obscuring the surface and margins.

Wright rabbit tobacco, Pseudognaphalium canescens, California, White Mountains, Falls Canyon, Hammil Valley - Owens Valley watershed, elevation 2048 m (6720 ft).

This is a common species of rocky places across interior southwestern North America and northern Mexico, and found up to middle elevations in the mountains. This is the only known location in the White Mountains, which represents the northwestern limit of the species range. The species is mostly perennial in the northern part of its range, and more frequently annual farther south.

bog star, Parnassia palustris, California, White Mountains, Falls Canyon, Hammil Valley - Owens Valley watershed, elevation 2050 m (6725 ft).

The Parnassia in this part of eastern California are often considered intermediate between P. palustris and P. parviflora, and have been called by both names, so I am using the older of the two names for these plants. This is one of a very few spots in the White Mountains where the water is dependable enough long-term to support a Parnassia population. Parnassia palustris is widespread in wet places throughout western and northern North America and circumboreal across Eurasia, from sea level to alpine elevations in the mountains.

horseweed, Erigeron canadensis, California, White Mountains, Falls Canyon, Hammil Valley - Owens Valley watershed, elevation 2047 m (6715 ft).

This native but weedy annual is found in moist and/or disturbed places throughout temperate and subtropical North and Central America, up to middle elevations in the mountains, and is introduced just about everywhere else in the world. The phase here with only sparse appressed hairs is sometimes referred to var. glabrata, and is native to western North America.

With such a mobile species, it's hard to distinguish native and introduced populations within its native range, though no doubt both kinds exist. Given the inaccessible location of this particular population, it is a good candidate for being native here, though it's seeds could always have blown up canyon from agricultural lands in the valley below.

A great swimmin' hole on a hot summer day, if you can get to it. A flowering stand of Nevada goldenrod (Solidago spectabilis) graces the wall at left.

The west side of the White Mountains is separated from Owens Valley by the White Mountains fault zone. The most rapid vertical displacement in this zone has been happening along the northwest edge of the range, rendering most of the drainages there impassably steep without technical equipment and skills. Falls Canyon is one of the more visible examples, but attempts to walk up (or down) most of the west-draining canyons north of White Mountain Peak eventually stop at views like this. At best one might be able to do a sketchy scramble up or down an adjacent ridge.

cliff goldenbush, Ericameria cuneata var. cuneata, California, White Mountains, Falls Canyon, Hammil Valley - Owens Valley watershed, elevation 1917 m (6290 ft).

I love this shrub for the intense golden patches it produces on otherwise bare cliff faces, usually in autumn when such vibrant color is most unexpected. The plant shown here was just getting started on September 3rd. This variety, characterized by having narrow heads and leaf margins tapered directly to the stem, is limited to the Sierra Nevada and southern California mountains, extending shortly eastward into the northwestern Mojave Desert and southwestern Great Basin of eastern California and extreme southwestern Nevada, from desert canyons up to middle elevations in the mountains. Two other varieties of the species extend farther south and east through the warm deserts of the southwestern U.S. and northwestern Mexico.

This warm season annual is locally common and somewhat weedy in loose sandy soils of valleys and foothills throughout the southwestern California and the western and northern Mojave Desert, extending shortly into the southwestern corner of the Great Basin (as here), and south into northern Baja California. The common name comes from the strong and distinctive odor of this heavily glandular species.

Similar to and often confused with the even more widespread Gutierrezia sarothrae, especially when not in flower, but sharply distinct by its smaller and narrower heads with only a single small ray flower and a couple of disk flowers in each one. Only this species appears to be present in and near the White Mountains.

skeleton buckwheat, Eriogonum deflexum var. deflexum, California, White Mountains, Wyman Canyon, Deep Springs Valley watershed, elevation 1823 m (5980 ft).

This annual species and variety is common and widespread in the warmer deserts of southwestern North America, extending northward shortly into the Great Basin, and from the valleys up to middle elevations in the mountains. Though native, it prefers loose soils on disturbed sites. The common name refers to the tall open stick-like branching pattern, and the resulting skeletons left after the plants die each year. The scientific name comes from the sharply bent (deflexed) stalks of the flower cups. This variety is distinguished from the others in the species by the combination of tall erect habit, flower cups with very short or no stalks, and heart-shaped flower parts.

pygmy poreleaf, Porophyllum pygmaeum, Nevada, Clark County, Desert National Wildlife Range, Sheep Range watershed, elevation 1355 m (4445 ft).

These are some poor, rushed film photos of plants gathered for the type collection of this species. I first noticed this unnamed species tucked away on an herbarium sheet at Rancho Santa Ana Botanic Garden, soon after arriving there as a graduate student. Fellow student Aaron Liston (@aaronliston), Garden employee Sara Meury, and I made a first unsuccessful attempt to relocate the species in the general area noted on the specimen in May 1987.

Visiting taxonomist Fritz Ehrendorfer and I made a second long trip for another attempt in early June. As seems to happen too often when so focused, we spent the whole day searching fruitlessly, until just before sunset and still 5 hours from home, when we finally located this large population. Thus the poor and rushed photos, restored as best I could from high resolution scans.

The species is still only known from the west base and slopes of the Sheep Range on the Desert National Wildlife Range in Clark County, Nevada.
