Oxytropis sericea Nutt.
White locoweed, Silky Locoweed
Fabaceae (Pea Family)
USDA Symbol: OXSE
A densely tufted, grayish, hairy plant with racemes of white or cream pea flowers held just above basal leaves on long stalks.
This species has been implicated in the poisoning of domestic livestock. In some areas it has purple petals, the result of hybridization with Purple Locoweed (O. lambertii), but the hairs on the hybrids leaves are attached by the base rather than by a bisecting stalk.
