Descripción

nodding buckwheat, Eriogonum cernuum, Nevada, White Mountains, Mustang Mountain, Pinchot Creek - Columbus Salt Marsh watershed, elevation 2830 m (9285 ft).

This annual buckwheat species is widespread in the interior of western North America, reaching its southwestern limit near this location, and ascending to subalpine elevations in the mountains. These plants appeared to be developing short secondary late-season flowering stems among the basal leaves.

ticklegrass, Agrostis scabra, Nevada, White Mountains, Mustang Mountain, Pinchot Creek - Columbus Salt Marsh watershed, elevation 2829 m (9280 ft).

This is a very widespread grass in its native range throughout most of North America up to middle elevations in the mountains, and in coastal northeast Asia, and is introduced in other parts of the world. Here in the White Mountains and the Great Basin it is generally restricted to wetland habitats.

curlleaf mountain mahogany, Cercocarpus ledifolius var. intermontanus, Nevada, White Mountains, Mustang Mountain, Sagehen Flat, Pinchot Creek - Columbus Salt Marsh watershed, elevation 2803 m (9195 ft).

This is a locally dominant shrub or small tree at middle to subalpine elevations throughout the intermountain region of the western United States between the Rocky Mountains and the Cascade-Sierra Nevada axes. This is the more southern and western variety of the species, with broader leaves, less curled margins, less hairy undersides. In the northeastern part of the species' range is the typical variety with narrower and more curled leaves with hairier undersides.

pinyon buckwheat, Eriogonum microthecum var. laxiflorum, Nevada, White Mountains, Sugarloaf, Sugarloaf Canyon, Pinchot Creek - Columbus Salt Marsh watershed, elevation 2618 m (8590 ft).

This variety is common in dry upland habitats at middle elevations in the intermountain region between the Rocky Mountains and the Cascade-Sierra Nevada axis of the western United States. About the only thing separating var. laxiflorum from yellow-flowered var. ambiguum is the white flower color, but the two varieties mostly seem to maintain separate populations. The var. ambiguum has a much more restricted geographic range in the northwestern Great Basin, but is completely surrounded by the larger range of var. laxiflorum.

whitebark pine, Pinus albicaulis, Nevada, Carson Range, Sierra Nevada, Mount Rose, Bronco Creek - Truckee River watershed, elevation 3133 m (10280 ft).

This western North American endemic is currently a candidate for Endangered Species listing, because of widespread declines and mortality from white pine blister rust and pine beetles. Most of the mortality has been in the main part of its range in the northern Rocky Mountains, with smaller amounts here near the southern end of its range.

Whitebark pine is unique among North American white pines in having cones that remain closed until torn apart by animals, or falling apart on their own. The animals (mostly Clark's Nutcracker and various small mammals) are very efficient at this, and if you aren't there while cones are still on the tree, often all you find is a litter of disarticulated cones scales on the ground. The species depends almost entirely on Clark's Nutcracker to disperse its seeds. Vegetatively the species is virtually identical to limber pine (Pinus flexilis), which causes ID problems where they grow together, unless cones are present.

pale mountain mint, Monardella odoratissima subsp. pallida, Nevada, Carson Range, Sierra Nevada, Spooner Summit, Carson Valley watershed, elevation 2169 m (7115 ft).

If not for some apparent intergrades, this would seem like a species distinct from the rest of Monardella odoratissima. It is characterized by the combination of (usually) white flowers, green reflexed leaves under heads, and small and narrow bracts well exceeded by the flowers, the outer often with leafy tips. The subspecies is endemic to higher mountains of the northern Californian Floristic Province, including adjacent southwestern Oregon and far western Nevada, and reaches the lower part of the subalpine zone.

Inyo cutleaf, Hymenopappus filifolius var. nanus, California, White Mountains, Westgard Pass, Cedar Flat, Owens Valley watershed, elevation 2234 m (7330 ft).

Hymenopappus filifolius is widespread through interior western North America, but this variety is more narrowly restricted to the Great Basin of Nevada, western Utah, and adjacent areas, reaching its western limit here in the White Mountains. It is found mainly on open rocky calcareous soils in the sagebrush and pinyon-juniper zones, and is a cousin of the sagebrushes so ubiquitous in this region.

Also visible in this image are Heller birdbeaks (Cordylanthus kingii helleri), squirreltail grass (Elymus elymoides), black sagebrush (Artemisia nova), and Utah juniper (Juniperus osteosperma).

Heller birdbeaks, Cordylanthus kingii subsp. helleri, California, White Mountains, Westgard Pass, Cedar Flat, Owens Valley watershed, elevation 2237 m (7340 ft).

This species is a spring or summer annual typical of the understory of pinyon-juniper woodlands and adjacent sagebrush vegetation, and is found throughout most of the Great Basin and almost all of Utah. Heller birdbeaks is the subspecies limited to the southwest corner of this range, from central Nevada westward into the Great Basin portion of eastern California. It reaches higher elevations, and is characterized by shorter flower parts, including more numerous bracts with shorter and broader lobes. The plants also tend to be more copiously glandular hairy.

All Cordylanthus species are considered to be hemiparasitic, possessing chlorophyll but also deriving some of their nutrients from the roots of other associated species. As plants of Heller birdbeaks develop, the chlorophyll is rapidly lost or masked by brownish purple pigments, lending pinyon-juniper woodlands a characteristic understory color after especially wet spring or summer seasons.

goatheads, Tribulus terrestris, California, Deep Springs Valley, Deep Springs College, Inyo Mountains watershed, elevation 1591 m (5220 ft).

One of the invasive annuals I most love to hate. Or as said in the noted scholarly work, Intermountain Flora, "a vile weed." It's reputation is well deserved. Also known as puncturevine and caltrops, there are few non-metallic materials that the spiny fruits of this species cannot penetrate, including tires and thick leather gloves. Like the ancient weapon of war known as caltrops, the fruit segments tend to land with one barbed spine pointing upward, just waiting for a victim. (The name "goatheads" is also based on the shape of the fruit segments.)

Every species has a home, and this one is said to be native to the Mediterranean region, but as easily as it hitches rides on animals and vehicles (modern and ancient), it is hard to define native versus introduced ranges for it. In any case, it has now spread to most warmer parts of the terrestrial world, and is on the official noxious weed lists in many jurisdictions. Needless to say, this individual met its demise in a burn barrel (along with several others in the area) as soon as photography was complete.

Two specialized weevil species from India were brought into California for biological control of this species in the 1960s, but have only been partially successful since that time.

sego lily, Calochortus bruneaunis, California, White Mountains, Westgard Pass, Cedar Flat, White Mountain Road, Owens Valley watershed, elevation 2233 m (7325 ft).

Named for Bruneau Creek in southern Idaho, this species occurs from the Snake River watershed (and adjacent mountains) southwest across northwestern Nevada to the east base of the Sierra Nevada, reaching its southwest limit near this location in the White and Inyo mountains. It is found from sagebrush valley bottoms up to the upper limit of pinyon-juniper woodlands in the mountains.

The geographic range above is bracketed by two other very similar white sego lily species. To the east and south, from the Rocky Mountains to eastern and central Nevada, is the state flower of Utah, Calochortus nuttallii. It differs by lacking a prominent green stripe on the backs of the petals, and averaging hairier on the interior petal bases, and lighter in anther color. In the Sierra Nevada to the west is Calochortus leichtlinii, with petals also scarcely striped on back, and with anthers white or nearly so. The anthers of Calochortus bruneaunis are usual dark reddish-purple.
