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 sharsmithii is a small perennial herb forming dense mats or cushions of hairy, oval-shaped leaves each no more than a centimeter long. The erect inflorescence bears several yellow flowers. The fruit is a twisted, lance-shaped silique up to 2 centimeters long containing several unwinged seeds.
Draba sharsmithii is endemic to the southern Sierra Nevada of California, where it is known from fewer than ten occurrences in rocky alpine and subalpine habitat.
Carl William Sharsmith was an American naturalist and Yosemite park ranger, notable for his knowledge and interpretation of the natural history of the Sierra Nevada. He taught botany at various universities, and was the first botanist to comprehensively document the alpine flora of the high Sierra Nevada.
Helen Katherine Myers Sharsmith was an American biologist.
Draba albertina is a species of flowering plant in the mustard family known as slender draba or slender whitlow-grass. This plant is native to western North America, where it grows at high elevations from Arizona to Alaska and northern Canada. Like many species of Draba, it can grow in alpine and Arctic climates. This is a biennial or short-lived perennial with a single stem or several branching stems which may be very short or up to 40 centimeters in height. The appearance of the plant varies depending on the climate it endures. The leaves are up to 4 centimeters long, roughly hairy, and mostly basal. The stem bears an inflorescence of up to about 30 small yellow flowers. The fruit is a silique up to two centimeters long.
Draba aureola is a species of flowering plant in the family Brassicaceae known as the Mt. Lassen draba or Mt. Lassen whitlow-grass. This plant is native to the Cascade Range of western North America, where it grows at elevations above 2000 meters. This is usually a perennial plant found growing in rocky areas such as volcanic cliffs and scree. It has one or more short, stout stems which are covered in stiff hairs. The leaves grow in a dense basal clump at the ground. They are fat and fleshy and covered in a carpetlike coat of stiff, light colored branching hairs. The stem may be erect above the clump of leaves or its inflorescence may rest directly upon them. The spherical or club-shaped inflorescence may have up to 80 small yellow flowers packed densely in it, each petal about 5 millimeters wide. The fruit is a wavy-edged, hairy silique about a centimeter long and half a centimeter wide.
Draba cruciata is a species of flowering plant in the family Brassicaceae known as the Mineral King draba. This is an uncommon plant endemic to California, where it is known only from the Sierra Nevada in Tulare County. It was named for Mineral King, a historic valley in the area. This plant is a squat, mat-forming perennial adapted to high mountain climates. It has small paddle-shaped leaves covered in a thick coat of hairs. It bears an inflorescence of 5 to 20 yellow flowers, each flower about a centimeter across. The stem bears widely spaced fruits, which are siliques about a centimeter long each.
Draba densifolia is a species of flowering plant in the family Brassicaceae known as the denseleaf draba. This small perennial is native to western North America, where it is found in mountain environments above 2000 meters from California to Alaska to Wyoming. The plant forms cushion-like mats of small fleshy, hairy, pointed leaves in rocky crevices and on slopes. If it bolts a stem it is no taller than 15 centimeters. The flowers open in an obvious inflorescence of a few tiny blooms at times, but often appear as a layer on the surface of the mat of tiny leaves. The flowers are bright yellow with petals just a few millimeters wide. The fruit is a flat podlike silique less than a centimeter long.
Draba subumbellata is a species of flowering plant in the family Brassicaceae known by several common names, including parasol draba, mound draba, and White Mountains cushion draba. This small perennial plant is native to the White Mountains which straddle the California-Nevada state line and the Inyo Mountains nearby. It lives on barren rocky scree above 3000 meters.
Campanula sharsmithiae is a rare species of bellflower known by the common names Mt. Hamilton bellflower and Sharsmith's harebell. It is endemic to California, where it is known from just a few occurrences in the higher mountain peaks just south of the San Francisco Bay Area, including Mt. Hamilton and Mount Boardman in the Diablo Range. It is a small, hairy annual herb producing an erect stem up to 25 centimeters tall. The fleshy, toothed leaves are a centimeter long or less. The flower is funnel- or bell-shaped and purple in color. The plant is named for late local botanist Helen Sharsmith.
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 carnosula is a rare species of flowering plant in the family Brassicaceae known by the common name Mt. Eddy draba. It is endemic to the Klamath Mountains of far northern California, where it is known from fewer than twenty occurrences at Mount Eddy and other peaks in the range. This is a perennial herb forming small clumps in serpentine outcrops. The leaves are located at the base of the plant, each an oval shape under a centimeter long. They are mostly hairless, except for long hairs along the edges. The erect inflorescence bears fewer than 10 yellow mustardlike flowers. The fruit is a lance-shaped silique one or two centimeters long, containing several winged seeds.
Draba howellii is a species of flowering plant in the family Brassicaceae known by the common names rosette draba and Howell's draba.

It is a plant of rocky habitat, such as talus. It is a hairy perennial herb up to about 30 centimeters tall. Most of the leaves are located around the base of the plant, reaching up to 14 centimeters long. Leaves higher on the stem are shorter and narrower. The hairy inflorescence is an open array of branches, each a coiling panicle of light blue flowers. The fruit is a cluster of nutlets, sometimes bearing prickles.
Primula capillaris is a rare species of flowering plant in the primrose family known by the common name Ruby Mountains primrose, or Ruby Mountain primrose. It is endemic to Nevada in the United States, where it is limited to the Ruby Mountains of Elko County.
