Pods brown, glabrous or pubescent, 4-8.5 x 1.5-2 cm, straight or almost so, flattened, margins often ± undulate, dehiscing longitudinally. Seeds dark brownish-black, 6-7 x ±3.5 mm, smooth, compressed; caruncle conspicuous; areole 3.5-4 x ±1.5 mm.
Unarmed tree to 5 m high. Branchlets glaucous, with dense, rigid hairs 0.4-0.6 mm, rarely glabrous. Phyllodes with dense straight hairs, sometimes glabrescent, elliptic or ovate, top acute, obtuse, or rarely retuse, mucronulate, sometimes slightly undulate, main vein closer to the dorsal margin, penniveined, 2-5 by l-2(-2.7) cm, 1.4-2.5 times as long as wide, pulvinus 1-2 mm, with a usually inconspicuous gland, (0.5-)0.8-2 cm above the base. Heads formed of 20-30 flowers grouped in racemes, with indumentum similar to that of the branchlets. Flowers yellow, pentamerous, bisexual. Pod flat with prominent margins, up to 9 by c. 2 cm, glaucous, sofdy hairy. Seeds longitudinal, 6.5-7.5 by 3-4 mm, pleurogram open, funicle thickened into a clavate aril.
