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]
Draba albertina is a plant that may grow as a short-lived perennial or a biennial plant, but most often is an annual plant. When full grown they range in size from 3–42 centimeters, but most often will be 5–30 cm tall. [3] The stems may be simple or have branches towards their ends while having short, soft hairs covering the lower portions, [4] and may be similarly pubescent or hairless towards their ends. [3]
The leaves are mostly found at the base of the plant and may either have leaves on the stems or they may be absent. [4] The basal leaves are attached to the plant by short stems and range in length from just 0.3 centimeters to as much as 3.5 cm. The surfaces of the leaves are also usually pubescent. [3] Plants usually have one to three cauline leaves directly attached to the stems (sessile), but may occasionally lack them or have as many as five. [4]
The stem bears an inflorescence of with two to thirty small yellow flowers. [4] The fruit is a silique, a type of narrow pod made up of two fused carpels, most often ranging in length from 6–12 millimeters, but occasionally as short as short as 4 mm or as long as 15 mm. [4] [3]
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. [5]
Aquilegia coerulea, the Colorado columbine, Rocky Mountain columbline, or blue columbine, is a species of flowering plant in the buttercup family Ranunculaceae, native to the Rocky Mountains and some of the surrounding states of the western United States. It is the state flower of Colorado. The Latin specific name coerulea means "sky blue".
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.
Triteleia ixioides, known as prettyface or golden star, is a monocotyledon flowering plant in the genus Triteleia. It is native to northern and central California and southwestern Oregon, where it can be found in coastal and inland coniferous forests and other habitat. It is a perennial wildflower growing from a corm. It produces one to two basal leaves up to 50 centimeters long by 1.5 wide. The inflorescence arises on an erect stem up to 80 centimeters tall. It is an umbel-like cluster of several flowers each borne on a pedicel up to 7 centimeters long. The flowers are variable in size, measuring one to nearly three centimeters in length. They are pale to bright yellow, or sometimes purple-tinged white. There are six tepals with darker midveins in shades of green, brown, or purple. The lobes are funnel-shaped and may open flat or somewhat reflexed. The six stamens form a fused tube that protrudes from the corolla; they have broad, flat filaments and whitish, yellowish, or blue anthers.
Turritis glabra, commonly known as tower rockcress or tower mustard, is a tall, slim, grey-green plant with small creamy flowers at the top of the stem. It usually grows on poor chalky or sandy soils, in open situations. It is native to Europe, Asia, and North Africa, and it is widespread in North America where it is also probably native. It can be found in many other parts of the world as an introduced species.
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.
Camissoniopsis bistorta is a species of flowering plant in the evening primrose family known by the common names southern suncup and California suncup. It is native to southern California and Baja California, where it grows in several types of plant community along the coast and in the coastal hills and mountain ranges. This is a hairy annual or short-lived perennial herb spreading from a basal rosette, with stems reaching up to 80 centimeters long. The leaves are narrow and sometimes toothed, and 1 to 12 centimeters in length. Toward the end of the spreading stems are nodding inflorescences of flowers, each flower with four bright yellow petals dotted with red at their bases.
Quercus havardii is a deciduous, low-growing, thicket-forming shrub that occupies some two million to three million hectares in the southern Great Plains of North America. Clones may reach hundreds to thousands of years old, although aboveground stems typically live only 11 to 15 years. Shinnery oak stems are usually 1 to 2 metres tall and codominate the plant community with mid- and tall-grasses, which are usually taller than the oaks.
Stemodia durantifolia is a species of flowering plant in the plantain family commonly known as the whitewoolly twintip and purple stemodia. Stemodia durantifolia is native to the Americas, including Chile, Mexico, Texas, and the deserts of California and Arizona, and is often found in riparian habitats, preferring wet sand and rocks. It is a perennial herb producing a hairy, glandular, erect stem 10–100 cm (3.9–39.4 in) tall, with the toothed lance-shaped leaves found in pairs or triplets, attached to the stem with clasping bases. The inflorescence is a raceme of violet flowers, with each corolla held in a calyx of hairy, pointed sepals, and can often be found in bloom year-round. Although globally at low risk of extinction, Stemodia durantifolia is imperiled in California due to its rarity and threats from development.
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.
