Draba albertina is a species of flowering plant in the mustard family known as the Arc dome draba,slender draba or slender whitlow-grass. [2]
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. [3]
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, but there may also be some sessile leaves along the stem. [4] The stem bears an inflorescence of up to about 30 small yellow flowers. The fruit is a silique up to two centimeters long.
Draba aizoides is a species of flowering plant in the family Brassicaceae, known as yellow whitlow-grass. It is native to Europe where it is found on limestone rocks and walls. In the British Isles it is found only on the Gower Peninsula in Wales.
Lepidium draba, also known as whitetop, hoary cress, or Thanet cress, is a rhizomatous perennial flowering plant in the family Brassicaceae. It is native to western Asia and southeastern Europe and has been widely introduced elsewhere.
Draba verna, common whitlowgrass, is a species of plant in the cabbage family. It is a small spring-flowering annual which is widely dispersed around the world, and which is found on walls, pavements and patches of bare ground. It has a complex taxonomy which is not yet fully elucidated.
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 cuneifolia is a species of flowering plant in the family Brassicaceae known as the wedgeleaf draba or wedgeleaf whitlow-grass. This annual plant is native to the southern half of North America where it grows in open, rocky fields and other disturbed areas. The plant forms a basal cluster of leaves, which are thick, widely toothed, and coated in stiff hairs. It bolts one or more erect stems which may approach 40 centimeters in maximum height. Each hairy stem bears an inflorescence of up to 75 small white flowers that continue at intervals down the stem as the stem grows in height. This family and its plants are easy to identify with its 4 petals and 4 sepals arranged like a "cross", either in an "X" or "H" shape, thus the name "Cruciferae". Mustards have 6 stamens usually 4 are taller and 2 are shorter. Fruits are either a long thin silique or short often rounded silicle.
Draba densifolia is a species of flowering plant in the family Brassicaceae known by the common names Alpine Whitlow-Grass and 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. Grows in alpine rocky slopes, barren outcrops.
Draba asterophora is a species of flowering plant in the family Brassicaceae known by the common names Lake Tahoe draba or Tahoe Whitlow-grass. This rare plant is known only from the Mount Rose and Slide Mountain areas of the northern Carson Range in extreme western Nevada, in and just outside of the Lake Tahoe drainage basin. 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 mustard-like 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, Lanceleaf 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.
Poa glauca is a species of grass known by the common names glaucous bluegrass, glaucous meadow-grass and white bluegrass. It has a circumboreal distribution, occurring throughout the northern regions of the Northern Hemisphere. It is also known from Patagonia. It is a common grass, occurring in Arctic and alpine climates and other areas. It can be found throughout the Canadian Arctic Archipelago in many types of habitat, including disturbed and barren areas.
Sporobolus hookerianus is a species of grass known by the common name alkali cordgrass.
Draba fladnizensis is a species of plant in the family Brassicaceae known by the common names arctic draba, Austrian draba, and white arctic whitlow-grass. It has a circumpolar distribution, occurring throughout the northern latitudes of the Northern Hemisphere. It is present in Europe, Asia, and North America from Alaska across northern Canada to Greenland. Its distribution extends south through the higher elevations in the Rocky Mountains to Colorado and Utah. It is common and widespread in the Canadian Arctic Archipelago, occurring on several Arctic islands including Baffin, Devon, and Ellesmere Islands. It is named after the Austrian village of Flattnitz, in the Gurktaler Alpen.
Draba exunguiculata is a species of flowering plant in the family Brassicaceae known by the common names clawless draba and Grays Peak draba. It is endemic to Colorado in the United States.
Draba graminea is a species of flowering plant in the mustard family known by the common names Rocky Mountain draba and San Juan Whitlow-grass. It is endemic to the state of Colorado in the United States, where it is limited to the San Juan Mountains.

Draba weberi is a species of flowering plant in the family Brassicaceae known by the common names Weber's whitlow-grass and Weber's draba. It is narrowly endemic to Summit and Park Counties, Colorado, where several populations were estimated to total to approximately 300 individuals as of 2012. D. weberi is principally threatened by alterations to its hydrologic environment, owing to its preference for wet, rocky streamside crevices.
Draba norvegica is a species of flowering plant in the mustard family (Brassicaceae) know by the common names Norwegian draba and Norwegian whitlow grass.
