Astragalus reventiformis

Yakima Milkvetch

Spreading, with numerous stems 8–15 in. Leaves erect to spreading, with many oblong to linear leaflets. Leaflets to 1/2 in. long, covered with ash-colored rigid hairs beneath or on both sides. Flower stalks erect, about 8 in. tall, with a loose head 2–3 in. long, cream to white flowers. Calyx has black hairs. Seedpod oblong, without hairs. Grows in dry areas, sagebrush deserts, grassy hills, stony hilltops. Much like A. hoodianus, which has white hair on calyx and seedpods with long hairs. Astragalus sclerocarpus is somewhat more sprawling, has black hairs on seedpods, which are curved like a crescent moon when dry; grows on sand along both sides of Columbia River upstream from The Dalles.
