herbaceous or suffruticose, erect, divaricately branched; branches angular and striate, thinly canescent; stipules none; leaflets on long petioles, elliptic oblong, or obovate, obtuse, mucronulate, glabrous or very minutely strigoso-puberulent bebeneath; racemes terminal, densely many-flowered, elongate; calyx appressedly pubescent, its teeth acuminate, about equalling the tube; carina falcate, twice as long as the alæ; legume sub-sessile, elongate, hook-pointed, many-seeded, minutely downy. A large species, but with moderate flowers. Petioles 2–3 inches long, leaflets 2–2 1/2 inches long, 1–1 1/2 inch broad, petiolulate, somewhat acute at base, tipped with a minute bristle-like mucro, mostly obtuse, rarely ovato-lanceolate and sub-acute. The very young buds and branchlets are somewhat woolly; the mature very thinly pubescent and whitish. Racemes 6–8 inches long, 40–50 flowered; flowers yellow, streaked with purple, pendulous: the vexillum and alæ much shorter than the carina. Legume 1–1 1/2 inch long, 2–2 1/2 lines in diameter, the upper suture depressed. This species occurs throughout the tropics of both hemispheres.
