Spreading, multi-stemmed shrub mostly 1–4 m high. Bark grey to reddish brown, mostly smooth but sometimes rough and somewhat fibrous at base of main stems on oldest plants. Branchlets angular to flattened towards apices, light brown or reddish, glabrous. Phyllodes linear, straight or upwardly curved, flat, (8–) 10–18 (–20) cm long, (1–) 2–4.5 (–8) mm wide, coriaceous, usually pale yellowish green or milky green when dry, glabrous; longitudinal veins numerous with central vein more pronounced than the others; minor veins obscure and c. 8–10 per mm; gland 1, basal, swollen, to 3 mm above pulvinus. Peduncles 5–15 mm long, often about as long as the spikes. Spikes 0.8–2.5 cm long, densely flowered, yellow. Flowers 5-merous; calyx 0.8–1.25 mm long (exceeding ½ length of corolla), dissected by less than 10%, with densely scurfy viscid lobes and midrib commonly evident; corolla 1.2–1.8 mm long, dissected to c. ⅓ its length, glabrous; ovary glabrous or apex very finely tomentose. Pods linear, slightly raised over and constricted between seeds, straight or slightly curved, 3.5–12 cm long, 2–3.5 mm wide, firmly chartaceous to thinly crustaceous, light brown. Seeds longitudinal, narrowly oblong to oblong-elliptic, dorsiventrally flattened, 3–4.5 mm long, dark brown to blackish; areole small, open with U-shaped pleurogram, paler than rest of seed; aril rather large, convoluted and bright yellow.

An evergreen shrub. It grows up to 2-4 m tall and spreads out 3-8 m wide. The stems can be 10-15 cm across. It has many stems which are thin and stick upright. The bark is brown and flaky. Young growth is covered with a sticky substance. The leaves (phyllodes) are greyish-brown. They are 10-13 cm long, narrow (0.2-0.4 cm) and thick. The flowers are short golden rods. These are 1.5 cm long. Pods occur in dense coiled clusters. They are 7-9 cm long and linear. They are sticky. The seeds are small and narrow with a soft coat.
Reddish sandy and gravelly soils, on flat plains and hillsides, commonly in spinifex grassland communities, sometimes with eucalypts; at elevations up to 700 metres.
