Multistemmed shrub or tree (1–) 2–6 (–8) m high, with rather crooked trunks, the main branches somewhat contorted and ±horizontally spreading. Branchlets mostly glabrous. New shoots sericeous; hairs pale yellow aging silvery white. Phyllodes linear to very narrowly elliptic, straight to shallowly recurved, acute to acuminate with curved to uncinate tips, 6–11 cm long, (2–) 3–5 (–8) mm wide, coriaceous to subrigid, appressed-hairy to glabrescent, grey-green to bluish with silvery sheen, aging green; finely multistriate with numerous nonanastomosing veins; margins resinous, red-brown or sometimes yellowish; gland inconspicuous. Inflorescences simple or sometimes rudimentary racemes to 2 mm long; peduncles 2–6 (–8) mm long, sparsely to densely appressed puberulous, sometimes glabrous when in fruit; spikes 2–3.5 cm long, densely flowered, golden; receptacle with sparse to moderately dense spreading white or pale yellow (rarely light golden) hairs but often glabrous when in fruit. Flowers 5-merous; calyx dissected to c. ½ its length. Pods narrowly oblong to linear, turgid to ±subterete, 1–7 cm long, usually 6–9 mm wide, coriaceous–crustaceous to woody, turgid to ± subterete, glabrous or with appressed (W.A.) or ±patent (N.T. & S.A.) white hairs. Seeds longitudinal, oblong to elliptic, 5–7 × 4–5 mm (W.A.) or 4–5 × 3–3.5 mm (N.T. & S.A.), dark brown to ±black; aril terminal.
Often grows on hardpan plains in loam or sand, between mulga groves with limited spinifex. For further details see B.R. Maslin et al., Wattles of the Pilbara (2010).
