Astragalus inversus is a species of milkvetch known by the common name Susanville milkvetch.

Description

Astragalus inversus is a perennial herb with slender, wiry, mostly leafless stems growing 20 to 50 centimeters long. They grow upright or form a spreading clump. The leaves are up to 12 centimeters long and are made up of a few small, widely spaced narrow leaflets.

The inflorescence is a loose array of 5 to 12 pale to reddish pink flowers, sometimes tinted with yellow. Each flower is about a centimeter long.

The fruit is a hanging legume pod 2 to 3.5 centimeters long, narrow and flat in shape and drying to a hairy, papery texture.
