Draba lemmonii is a perennial plant in the family Brassicaceae found in the high elevation United States Sierra Nevada range, commonly known as Lemmon's draba. [1]
It is a hairy mat forming perennial growing to 6 inches (15 cm). [1]
It grows in crevices, talus, and rocky meadows of the subalpine forest and alpine zone of the United States Sierra Nevada range. [1]
Basal leaves are obovate, up to 1 inch (2.5 cm), and hairy on both sides. [1]
The flower stalk has up to 30 small, yellow, 4 petalled flowers on top in July of August. [1]
Polemonium eximium, the skypilot or showy sky pilot, is a perennial plant in the phlox family (Polemoniaceae) that grows at high altitudes. It is endemic to the Sierra Nevada in California where it grows in the talus of the high mountain slopes.
Hulsea algida is a species of flowering plant in the daisy family, known by the common name Pacific hulsea or alpine gold.
Hulsea vestita is a species of flowering plant in the daisy family known by the common name pumice alpinegold.
Eucephalus breweri is a North American species in the aster family known by the common name Brewer's aster. It is native to California where it grows primarily in the Sierra Nevada at subalpine elevations. Its range extends into northwestern Nevada and southwestern Oregon.
Draba asterophora is a species of flowering plant in the family Brassicaceae known by the common names Lake Tahoe draba or Tahoe Whitlow-grass. It is native to the High Sierra Nevada of California and western Nevada around the Lake Tahoe area. It is a squat perennial herb which forms small mats in rocky habitat in the alpine climate of the high mountains. It forms a basal patch of thick, hairy oval leaves up to 1.5 centimeters long. A small, erect inflorescence arises from the patch bearing several yellow mustardlike flowers. The fruit is a flat, wavy silique which is oval in shape, somewhat membranous, and up to 1.5 centimeters long. It contains several flat, round seeds with wide wings along the edges.
Draba breweri is a species of flowering plant in the family Brassicaceae known by the common names cushion draba, Brewer's draba, and Brewer's Whitlow grass. With Draba cana now considered a variety of this species, it is distributed throughout parts of northern and western North America, including much of Canada and the western United States. The less widespread var. breweri is limited to mountainous California and western Nevada.
Draba sharsmithii is an uncommon species of flowering plant in the family Brassicaceae known by the common names Mt. Whitney draba and Sharsmith's draba.
Draba sierrae is an uncommon species of flowering plant in the family Brassicaceae known by the common name Sierra draba. It is endemic to the central Sierra Nevada of California, where it is known from just a few occurrences in rocky alpine habitat. It is a perennial herb forming small, dense cushions of very hairy, oblong or lance-shaped grayish leaves each under centimeter long. The erect inflorescence bears several yellow flowers. The fruit is a flat, twisted, oval-shaped silique under a centimeter long containing a few unwinged seeds.
Hymenoxys hoopesii is a species of flowering plant in the daisy family known by the common names owl's claws, orange sneezeweed, and yerba del lobo. It is native to the western United States, where it grows in habitats of moderate elevation, such as mountain meadows in the Rocky Mountains, Sierra Nevada, southern Cascades, and other ranges. It has been found from Arizona, New Mexico, and central California north as far as Montana and Oregon.

Packera werneriifolia, known by the common names alpine rock butterweed and hoary groundsel, is a species of flowering plant in the aster family. It is native to the western United States in the Sierra Nevada mountain habitat in subalpine and alpine climates, including forests and barren talus.
Hydrophyllum capitatum, is a species of waterleaf known by the common name ballhead waterleaf. It is native to Western North America from British Columbia to Utah.
The flora of the U.S. Sierra Nevada alpine zone is characterized by small, low growing, cushion and mat forming plants that can survive the harsh conditions in the high-altitude alpine zone above the timber line. These flora often occur in alpine fell-fields. The Sierra Nevada alpine zone lacks a dominant plant species that characterizes it, so may or may not be called a vegetation type. But it is found above the subalpine forest, which is the highest in a succession of recognized vegetation types at increasing elevations.
Lupinus lepidus, the Pacific lupine, prairie lupine or dwarf lupine is a perennial herbaceous plant in the pea family (Fabaceae) endemic to western North America. Many varieties have been described, several of which are considered separate species by some authorities.
