Shrub or tree to 8 m tall, single-stemmed, round-topped. Bark smooth at first, later rough and fibrous, grey-brown. Branchlets markedly angular, flattened, stout, brownish crimson, normally pruinose, glabrous. Phyllodes obliquely narrowly elliptic to elliptic, narrowed abruptly into broad pulvinus, with lower edge of phyllode sometimes continuous with branchlet; normally shallowly to obviously falcate but sometimes straight-dimidiate, 7–14 cm long, (12–) 17–40 mm wide, with hooked apex, coriaceous, silvery grey-blue to glaucous, glabrous, with 2 or 3 prominent main nerves free to base or lower two contiguous but remaining free from lower margin; minor nerves sub-distant (2–4 per mm, longitudinally anastomosing; gland 1, basal, to 1 mm above pulvinus. Spikes 4–12 cm long, bright yellow, flowers sub-dense to widely spaced; peduncles 7–25 mm long. Flowers 5-merous; calyx 0.4–0.6 mm long, dissected to ¼ of length, glabrous; corolla 1.2–1.5 mm long, dissected to ½ of length, glabrous; ovary glabrous or pubescent. Pods linear, raised over and ±constricted between seeds, 6–10 cm long, 3–5 mm wide, thinly crustaceous, glabrous, ±resinous. Seeds longitudinal, oblong-elliptic, 4–6 mm long, 1.8–2 mm wide, black; aril yellow.
Grows in eucalypt open forest, in sandy, gravelly or loamy soils, usually over sandstone.
