Oxytropis splendens Douglas ex Hook.
Fabaceae (Pea Family)
Synonym(s): Aragallus splendens, Astragalus splendens, Oxytropis richardsonii, Oxytropis splendens var. richardsonii, Oxytropis splendens var. vestita
USDA Symbol: OXSP
Tufted plant with silvery, silky-hairy, leafless stems, topped by dense spikes of rich lavender flowers, rising from among pinnately compound basal leaves.
This is one of the poisonous locoweeds, similar to the members of the genus Astragalus (whose flowers have a blunt keel), which are also known as locoweeds or poison vetches. There are nonpoisonous members of both genera as well--those of Oxytropis are known as point-vetches.
