Obconic, multi-stemmed, glabrous shrub 0.5–2 (–3) m high; crown dense, with soft, delicate foliage. Branchlets light brown but reddish brown or yellowish at extremities, often with a thin ±waxy finely cracked resinous coating, obscurely ribbed. Phyllodes linear to narrowly oblong or linear-oblanceolate, erect, flat, ±straight, (2–) 2.5–6 (–8) cm long, 1–4 (–6) mm wide, coriaceous, puncticulate by evident (x10 mag.) stomata, light green (at least when young) to distinctly subglaucous or grey-green, with a sweet fragrant smell when young; veinless or with an obscure central vein, occasionally with 1 or 2 less prominent additional longitudinal veins; gland 1, inconspicuous, 0.2–2 mm above pulvinus. Spikes 1–2.4 cm long, golden. Flowers 5-merous; calyx gamosepalous, dissected to ¼–⅚ of length. Pods erect, linear-oblanceolate, terete to flat or ±quadrangular, (3–) 4–6.5 (–8) cm long, woody, obscurely longitudinally striate, resinous, opening elastically from apex (dehisced valves shallowly to strongly recurved); margins inconspicuous; seed partitions distinct but narrow. Seeds retained in pods following dehiscence, oblique and seated in distinct chambers, narrowly oblong-elliptic, 4.5–7 mm long, brownish black; funicle-aril narrowly turbinate.
