Tree to 13 m high, single-stemmed. Bark ribbony, grey. Branchlets angular towards apices, red-brown, scurfy, glabrous, ± resinous. Phyllodes narrowly to very narrowly elliptic, flat, straight or slightly curved, (2–) 3–11 cm long, (2–) 4–10 mm wide (juveniles to 14 mm wide and scurfy), coriaceous, with 1–3 slightly prominent main veins; minor veins 8–10 per mm, parallel, not anastomosing; gland 1, basal, to 1 mm above pulvinus. Inflorescences racemose; raceme axes 1–5 (–8) mm long, sometime growing out at apex. Spikes 1.5–3 cm long, golden. Flowers 5-merous; calyx 0.5–0.8 mm long, dissected to ⅙–¼ of length, glabrous or slightly pubescent; corolla 1.5–1.8 mm long, dissected to ½ of length, glabrous; ovary scurfy, sometimes pubescent. Pods linear, slightly constricted between seeds, mostly straight or slightly curved, 4–11 cm long, thinly coriaceous to crustaceous, glabrous, resinous. Seeds longitudinal, oblong-elliptic, 3–4.5 mm long, dark brown to black; pleurogram without halo; areole open.
