Characteristics

Erect single-stemmed tree to 10 m high. Bark smooth towards top, rough and fibrous at base, dark brownish grey. Branchlets angular, stout, tawny yellow to pale maroon, ± pruinose, with minute, appressed hairs. Phyllodes very narrowly elliptic to elliptic, oblique, flat, sometimes dimidiate but more commonly shallowly to obviously falcate, (8–) 10–19 cm long, 13–46 mm wide, usually larger on juvenile than adult plants, coriaceous, silvery grey to glaucous, occasionally silvery green, usually appressed-puberulous, sometimes glabrous, with 3 main prominent veins (lower 2 often running together near base and often close to lower margin but not confluent with it) and conspicuous marginal veins; minor veins subdistant (3–5 per mm), some longitudinally anastomosing; gland 1, basal, large, to 1 mm above pulvinus. Spikes 3–10 (–12) cm long, golden, the flowers dense to sub-dense or sometimes ± widely spaced; peduncles 3–10 (–12) mm long. Flowers 5‑merous; calyx 0.5–0.8 mm long, dissected to ⅙, pubescent sometimes only at base; corolla 1.5–1.8 mm long, dissected to c. ½, glabrous; ovary densely pubescent. Pods slightly moniliform, curved, twisted, 3–11.8 cm long, 2.5–3.5 mm wide, thinly crustaceous, occasionally slightly longitudinally ridged over seeds, glabrous, dark brown. Seeds longitudinal, 2.5–4.5 mm long, dark brown; areole almost closed (further material needed); aril yellow.
