Glabrous shrub to 1–5 m high. Branchlets slender, angular, dark reddish brown. Phyllodes narrowly oblanceolate or occasionally narrowly elliptic, straight to shallowly incurved, size variable, (3.5–) 4–8 (–9) cm long, (3–) 4–9 (–11) mm wide, obtuse, with 3–7 rather indistinct, widely spaced longitudinal veins and sometimes with obscure longitudinally anastomosing minor veins in between; gland obscure, (3–) 4–10 (–13) mm above pulvinus. Inflorescences simple or rudimentary racemes 0.5–1.5 mm long, 1–5 per axil; peduncles slender when in flower (thicker in fruit), 5–10 (–15) mm long, with basal bract persistent; heads globular, c. 5 mm diam., 20–30-flowered, golden; bracteoles obtuse, inconspicuous in buds. Flowers 5-merous; sepals free. Pods linear, slightly to moderately constricted between the seeds and strongly domed over them alternately on each side (convexity extending to the margin), with a depression on the valve opposite the convexity, to 9 cm long, 5–6 (–7) mm wide. Seeds longitudinal, oblong, 3.2–4 mm long, black, not markedly shiny; funicle expanded into a keeled leaf-like aril on one side of seed.
Grows above 500 m altitude on shallow sandy soils often derived from sandstone, reportedly in association with Corymbia trachyphloia or Acacia shirleyi and occasionally at lower elevations on sandy creek banks.
