suffruticose, erect; stem and branches straight, rib-striate and angular, pubescent or hairy; leaves shortly petiolate, suberect, 5–9 jugate; leaflets subcuneate-oblong, pubescent on one or both sides, paler beneath and closely penninerved, mucronate; stipules subulate; peduncles axillary and terminal, elongate, laxly racemose; bracts subulate; legumes narrow, linear, pubescent or hairy, about 8-seeded. Stems 2–3 feet high, slender, strongly furrowed, with close or spreading, yellowish or foxy pubescence; branches and leaves suberect. Leaflets 1/2– 3/4 inch long, 2–3 lines wide (in β. longer, broader, thinner, and less hairy), flat or subcomplicate, sometimes recurved at point, the older often glabrate above. Peduncles longer than the leaves and ending in a distantly many-flowered, 4–6 inch long raceme. Flowers 3 lines long, the vexillum densely hairy. Pods 1 1/2 inch long, 1–1 1/2 line wide, straight or slightly curved, acute. β. appears to be a form from moister and more shady situations. In many respects this agrees with T. stricta, but differs in inflorescence.
