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 albertina is a species of flowering plant in the mustard family known as the Arc dome draba,slender draba or slender whitlow-grass.
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.
Carex chordorrhiza, commonly called creeping sedge or string sedge, is a species of perennial plant in the family Cyperaceae with Holarctic distribution growing in acidic bogs.
Carex canescens L. is a perennial species of plants in the family Cyperaceae growing in damp forests and wetlands. It is widespread across much of Europe, Asia, Australia, New Guinea, North America, Greenland and southern South America.
Carex capitata is a species of sedge known by the common name capitate sedge. It has a circumboreal distribution including Norway, Russia, Siberia, Alaska, Canada and Greenland. Growing in wet places in boreal forests and mountain meadows in alpine climates.
Carex lyngbyei is a species of sedge known by the common name Lyngbye's sedge. It is native to the west coast of North America from Alaska to California, where it "is the common sedge of the Pacific coastal salt marshes." It is also known from Greenland and Iceland. It prefers to grow in silty sediment rather than sand and in habitat with brackish water, such as salt marshes. This sedge produces stems 25 centimeters to well over one meter tall from a network of long rhizomes. The leaves have reddish brown sheaths which do not have spots. The inflorescence produces stiff, nodding spikes on peduncles. The fruit is coated in a leathery yellowish brown sac called a perigynium. This is a pioneer species, one of the first plants to colonize the mud of tidal flats in its range.
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.
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.
Arnica lonchophylla is a species of flowering plant in family Asteraceae. The common names for this species includes longleaf arnica, northern arnica, and spear-leaved arnica. It has daisy-like yellow flowers that are 2.5 to 5 cm across with a yellow center disks.
Carex capillaris, the hair-like sedge, is a species of sedge found in North America and northern Eurasia including Greenland.
Carex bicolor, the bicoloured sedge, is a species of sedge native to North America, Northern Europe and Northern Asia. The International Union for Conservation of Nature has assessed the plant's conservation status as being of least concern because it has a widespread distribution and faces no particular threats.
Draba norvegica is a species of flowering plant in the mustard family (Brassicaceae) know by the common names Norwegian draba and Norwegian whitlow grass.
