diffuse or prostrate, silky-pubescent; stipule mostly solitary, ovate or lanceolate, much shorter than the petiole; leaflets obovate or obcordate, glabrous above, silky beneath; peduncles elongate, opposite the leaf, 1 (rarely 2–3) flowered; bracts minute, setaceous; vexillum very ample, silky along the midrib, otherwise glabrous; legume turgid, thinly and minutely pubescent. Root woody, deeply descending; stems many, filiform, trailing. Petioles varying much in length, 1/4–1 inch long; leaflets 1/3– 1/2 inch long, 2–3 lines wide, mucronulate or emarginate, thickish, midribbed. Stipules variable in length and breadth, sometimes linear-subulate. Peduncles 2–4 inches long, jointed below the calyx. Calyx deeply parted, thinly silky, with lanceolate lobes. Legume 3/4– 7/8 inch long, 2 lines in diameter. Flowers yellow. Of var. γ. I have only seen a single small specimen, from which I cannot determine whether it be more than a mere variety.
