Leaves basal and cauline; lower petioles 3–10 cm long; leaflets 7 to 9, oblanceolate, sericeous on both surfaces, 2–5 cm long with acute tips. Racemes somewhat open, higher than the leaves, 5–15 cm long. Flowers blue; calyx tube 1–2 mm long, villous; upper lip 3–5 mm long, ca. as long as the lower; banner 8–12 mm long, pubescent on much of the back, reflexed 60° or more; wings 9–12 mm long. Legume 2–3 cm long (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).
