Shrub or tree to 2 (–3) m tall, erect, often spindly. Bark smooth, brown. Branchlets compressed, angular, orange or yellow towards apex, later reddish, glabrous. Phyllodes erect, narrowly elliptic to linear or narrowly oblong-lanceolate, straight, 6–14.5 cm long, (3–) 6–12 mm wide, thinly coriaceous; minor nerves 2–4 per mm, parallel, rarely anastomosing, hyaline, with stomata visible between nerves; midnerve raised, excentric towards base; gland 1, basal, minute. Spikes 2–3.5 cm long, interrupted, cream-coloured to pale yellow. Flowers 5-merous; calyx 0.7–0.9 mm long, dissected to ½–¾ of length, fimbriate; corolla 1.5–2 mm long, dissected to ±¾ of length, glabrous; ovary densely pubescent. Pods pendulous, cultrate to linear, ±abruptly tapered at both ends, mostly flat to subterete when dry (terete but drying subterete to depressed), 4.5–12.5 cm long, 4–7 mm wide, woody, dark to blackish brown, often with paler margins, glabrous, opening elastically from apex. Seeds longitudinal, narrowly oblong, 5.4–6.5 mm long, black, dull, pitted; areole open; funicle running along and past one side of seed.
