[oregonflora.org] Description, Identification Tips: Astragalus obscurus is recognizable by its few leaflets, small, dingy flowers ascending in a close raceme, and erect, sessile, linear-oblong, trigonously compressed fruits. It may be confused with the sympatric A. atratus, which is alike in general habit but has pendulous, decurved pods. (link added by Mary Ann Machi)
