| 説明 | 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 area in and around the trailhead to the College M. Similar to Astragalus canadensis but the petals are murky white (not bright whitish or cream) and the flowers are erect to ascending in bud but become 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). |
