General Description
Acaulescent. Herbage silvery strigose partly with dolabriform hairs. Leaflets 9 to 19, linear-lanceolate, 1–3 cm long. Stipules membranous, villous, 7–24 mm long, the free portion deltoid. Inflorescence of 6 to 18 flowers, 10–30 cm long including the peduncle. Flowers magenta, drying purple; calyx densely white-strigose; sepals 2–3 mm long, linear; banner 15–22 mm long. Legume erect, sessile, 1–2 cm long, including the long beak, leathery or woody, white-strigose (
