Flowers fade to light purples and steel grays and the inflated seed pods that follow are sharply narrowed and compressed on both ends, giving rise to the scientific name: the Greek "amphi", "on both ends" and "oxys", "sharp".

Compare this species with the very similar Astragalus missouriensis variety amphibolus.
