[nwwildflowers.com] Common Name Info: The vernacular name for Astragalus serenoi, naked milkvetch, refers to the persistent fruits borne naked because of the fragile calyx that is soon deciduous by a circumscissile fracture (R. C. Barneby 1964). The plant is coarse, scarcely leafy, with nearly zigzag stems. (link added by Mary Ann Machi)
