Flowers are pale yellow, with pedicels and calyces covered with short, appressed, black hairs.

Fruits have three longitudinal, keel-like, ''ridges'' (i.e. carinae): one medial carina above (with a suture running down its middle), and two lateral carinae below. Fruits are firm and leathery, rather than ''papery-inflated'' as in many other Astragalus species.

Stems have short sparse (mostly) white hairs below the inflorescences.
