Astragalus Linnaeus. Milkvetch, Locoweed.

Key to Astragalus

A genus of about 3000 species, herbs (annual, biennial, and perennial) and suffruticose shrubs, most diverse in arid regions of w. North America and w. and c. Asia. The habitats of the southeastern species may be characterized as rocky or sandy, “relictual islands” of aridity in the generally moist landscape of eastern North America.
