Multi-stemmed shrub or tree 2–5 (–7) m tall; stems with few to many shallow to deeply longitudinal flutings. Bark smooth but finely fissured at extreme base of stems on oldest plants. New shoots resin-encrusted, with sparse, reddish, glandular hairlets on young phyllodes. Branchlets resin-ribbed, appressed-puberulous between ribs. Phyllodes filiform, terete, rarely subterete, innocuous to coarsely pungent, sub-straight to shallowly incurved, (4–) 6–11 (–15) cm long, 0.6–0.8 (–1) mm diam., not rigid, grey-green or dull green; longitudinal nerves fine, numerous and close together, sometimes resinous. Inflorescences simple, mostly 2 per axil; peduncles 0.5–2 (–3) mm long (obscured by stamens at anthesis so heads appear sessile), stout, silvery-white appressed puberulous and with normally sparse, red-brown glandular hairlets; heads obloid to shortly cylindrical, rarely globular, 5–9 (–12) mm long, (4–) 5–6 mm diam., golden. Flowers 5-merous; sepals free to ½-united. Pods straight to slightly curved, terete, (2–) 4–8 (–10) cm long, 1–2 mm wide, thinly coriaceous-crustaceous, ±obscurely longitudinally nerved. Seeds longitudinal, oblong, 2.2–4 mm long, shiny, normally tan; arils creamy white.
Grows in a wide variety of soils including granitic or lateritic gravel, sand, sandy loam or loam, often on sandplains, but also on low hills and granite outcrops in shrubland and spinifex.
