The leaves are cylindrical and sometimes taper to a point, growing erect in a patch around the caudex. Each leaf is up to 10 centimeters long and is made up of crowded pairs of hairy leaflets. The inflorescence is an array of up to 15 flowers atop an erect stalk, each flower made up of five hairy, pointed, reflexed sepals and five white petals.
