Characteristics

Rather straggly shrub 1.5–3 m high. Branchlets terete, minutely stellate-velvety, rarely glabrous. New shoots usually golden-hairy. Stipules 1–1.5 mm long. Phyllodes inequilaterally elliptic, 3–10 cm long, 1.5–4 cm wide, rotund-obtuse, coriaceous, subglaucous, usually minutely stellate-velvety, with 3–5 raised main veins (some confluent with lower margin for c. 1 cm above pulvinus), prominently reticulate; gland basal, with 2–4 additional glands in shallow notches along upper margin. Inflorescences simple but forming terminal 'false' racemes by phyllode suppression; peduncles mostly 2 per axil, 15–30 mm long and golden stellate-hairy, stout, furrowed; heads globular, 7–8 mm diam., densely 100–135-flowered, golden. Flowers 5-merous; sepals ¼–½-united, with lobes densely golden-puberulous; petals apically golden-puberulous. Pods narrowly oblong, ± flat, to 8 cm long, 15–25 mm wide, firmly chartaceous to thinly coriaceous, transversely reticulate, stellate-puberulous; margins narrowly winged. Seeds transverse, oblong to elliptic-oblong, 5.5–6.5 mm long, dull, dark brown; aril terminal.
