Bishop milkvetch is a California native perennial found on the eastern edge of the central and southern Sierra Nevada Mountains and eastern Sierra Nevada in Inyo County, growing in dry, granitic sand within sagebrush and pinyon forest at elevations of 1,450 to 2,000 meters.

Its leaves are 2 to 8 centimeters long, composed of 7 to 17 obovate leaflets 3 to 14 millimeters long with notched or blunt tips. The fruit is a stiff-papery, somewhat incurved pod 15 to 20 millimeters long with fine, shaggy hairs.
