much branched, branches virgate or ramuliferous, silky; leaves erect, incurved or spreading, linear-oblong or lanceolate, acute, with strongly revolute margins, silky on one or both surfaces; calyx lobes shorter than the tube; legume ovate, turgid, acuminate. Erect or sub-erect, many-stemmed, 1–2 feet high; branches either quite simple or having lateral, erect, short twigs. Leaves 3–4 lines long, 1 line wide, more or less silky. Flowers in dense, terminal pseudo-spikes, similar to those of the preceding species. Intermediate states connect the two varieties, which I cannot always distinguish.
