It is native to the High Sierra Nevada of California and western Nevada around the Lake Tahoe area.[1] 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 mustardlike 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. External links
