Astragalus falcatus

Astragalus falcatus was likely introduced into this area as forage in pastures managed by the U.S. Forest Service. This population at the southern end of the Bridger Range has been persisting in good conditions for approximately 100 years. It is not yet found outside of this site in and around the "M" parking lot. Similar to Astragalus canadensis but the petals are murky white (not bright whitish or cream) and the flowers go from erect to ascending in bud to abruptly pendent or nearly so at anthesis (they are not splayed outward at anthesis). The growth habit is bunched (not rhizomatous as in A. candensis).
