Streptanthus Cordatus
''Streptanthus cordatus'' is a species of flowering plant in the Brassicaceae, mustard family known by the common name heartleaf twistflower. It is native to the western United States, where it can be found in many types of sagebrush, woodland, and forest habitat. It is a perennial herb producing a branched or unbranched stem up to about a meter tall. It is often waxy in texture. The basal leaves are oval or spoon-shaped with bristle-toothed blades borne on rough-haired Petiole (botany), petioles. Leaves higher on the stem are oval to lance-shaped, up to 9 centimeters long with their bases usually clasping the stem. Flowers occur at intervals along the upper stem. Each has a calyx of sepals roughly a centimeter long which begin greenish yellow and mature purple. Four purple petals emerge from the tip of each calyx. The fruit is a thin, narrow silique which may reach 14 centimeters in length or longer.

Streptanthus Cutleri
''Streptanthus cutleri'', known as Cutler's jewelflower, is a species of annual flower only found in the Big Bend region of Texas. Its specific epithet and common name both reference Hugh Carson Cutler, who first collected the plant in 1937. A second specimen was later collected when the plant was in fruit, and this holotype was collected at the exact location as the first specimen, in Maravillas Canyon near Black Gap. Its distinguishing characteristic is that only two petals of each its flowers is enlarged. Description ''Streptanthus cutleri'' grows in an entirely glabrous habit tall. Its terete stems are up to wide and are simple at their base but branch above. Plants have five to ten oblanceolate, sharply pinnatifid basal leaves borne on petioles. These purplish leaves are long and wide, with triangular apices. The ascending cauline leaves are as long or longer than the basal leaves and have narrower segments. Upper cauline leaves are linear, entire, or undulate. The purp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
