Draba asterophora
Draba asterophora is a species of flowering plant in the family Brassicaceae known by the common names Lake Tahoe draba or Tahoe whitlow-grass. This rare plant is known only from the Mount [Rose (Nevada)|Mount Rose] and Slide Mountain areas of the northern Carson Range in extreme western Nevada, in and just outside of the Lake Tahoe drainage basin. 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 mustard-like 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.
