stems herbaceous, rough with spreading hairs; pods linear, erect or spreading; leaves hairy, either oblong or linear, entire, or sometimes lobed near the apex, cuneate at base. A very variable species. Stem 6 inches to 1–2 feet high, erect or diffuse, simple or branched from the base. Lower leaves often opposite; the rest alternate, ovate, oblong, spathulate or lanceolate, 1/2–3 inches long, 2–6 lines wide. Racemes lax, at length elongated. Flower stalks 3–4, fruit stalks 6–8 lines long. Flowers rather large, sky blue, with a yellow centre. Pods at length smooth, 1–1 1/2 inches long, the valves somewhat convex or compressed, three-nerved; style thick, short, or longish, subcylindrical. Var. δ. is more slender, glabrous toward the apex; the leaves 6–12 lines long, 2–3 lines wide, the flowers lilac or yellow. Var. ε. (perhaps the same as H. divaricata, DC.) has leaves 6–8 lines long, a line wide, and glabrous; smaller, lilac or blue flowers and a conical style.
