Oxytropis lambertii Pursh

Purple locoweed

Fabaceae (Pea Family)

Synonym(s):

USDA Symbol: OXLA3

USDA Native Status: L48 (N), CAN (N)

A tufted plant, usually covered with silvery hairs, with dense racemes of bright reddish-lavender pea flowers held just above the basal leaves by long stalks.

The single feature that distinguishes Purple Locoweed from other American Oxytropis species is the hairs attached by their middle to a short stalk forming a miniature teeter-totter, a feature seen only with a lens and even then sometimes escaping notice.
