The stems are green in color with white hairs. Leaves are alternate, petiolate, and palmately 5-9 foliate. The leaflets are elliptic in outline, entire, and pubescent on both surfaces. Flowers are produced in a terminal raceme. Individual flowers are papilionaceous, blue in color, with white markings on the banner petal. The fruit is a legume with 3-10 seed.
