Shrub 0.3–3 m high. Branchlets terete to weakly angled, glabrous or ± villous to appressed-puberulous and glabrescent. Phyllodes straight or shallowly curved, terete to compressed, 1–3.5 cm long, 0.7–1.5 mm diam., ± gradually narrowed to a rather delicate curved acute to shortly acuminate (0.8–1.5 mm long) glabrous or appressed-puberulous tip, glabrous (sometimes villous on new shoots), with 8 distant raised to plane veins (often obscured by surface wrinkling in drying), 3-veined per face when compressed. Inflorescences simple, 2 per axil; peduncles mostly 4–5 mm long, puberulous to appressed-puberulous or glabrous; heads globular, 2.8–4.5 mm diam., 16–30-flowered, golden. Flowers 5-merous; sepals free; petals c. 1/2-united, occasionally free. Pods linear, slightly raised over and constricted between seeds, straight, 4–5 cm long, 2.5–3.5 mm wide, thinly crustaceous, glabrous or ± appressed-puberulous. Seeds longitudinal, elliptic or oblong-elliptic, 2.5–3.5 mm long, subglossy, mottled, nigrescent; aril subterminal, crested.
Grows in white or yellow sand, sandy loam or loam, on sandplains or hillslopes in undulating country, in Banksia-Casuarina scrub and Eucalyptus scrub-woodland.
