Draba aureola is a species of flowering plant in the mustard family
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.
