Draba albertina

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.

Taxonomy

Comments: Nevada Natural Heritage Program follows Rollins (1993) treatment, which lists Draba crassifolia var. nevadensis as a synonym of D. albertina. This treatment is also followed by Kartesz (1999 floristic synthesis).

Comments: Draba stenoloba var. ramosa is recognized by most floras as D. albertina. If recognized as a distinct variety, D. stenoloba var. ramosa is a rare variety. Flora of North America vol. 7 says that the limits of D. crassifolia, D. albertina and D. stenoloba were confused in the past. No specific information is reported for why D. stenoloba var. ramosa was lumped into D. albertina.
