This plant produces spreading and erect stems up to 25 centimeters tall from a caudex. The stems have a dense coat of hairs and have leaves alternately arranged. Each leaf is up to 3 to 4 centimeters long and is made up of leaflets measuring a few millimeters in length. The leaflets are covered in ashy gray hairs. The inflorescence is a raceme of up to 15 flowers with petals that are greenish, white, purplish, or pinkish with green veins and purple tips. The fruit is a hairless legume pod that matures deep red in color and measures up to 2.6 centimeters in length. It contains up to 12 seeds.[2][3]
