Shrub or tree 2–5 m tall, stems with few to many, shallow to deep longitudinal flutings. Bark smooth, rarely fissured near the base. New shoots resin-encrusted, with sparse, reddish, glandular hairlets on young phyllodes. Branchlets resin-ribbed, appressed-hairy between ribs. Phyllodes narrowly linear, flat, straight to shallowly curved, (4–) 6–10 (–14) cm long, (1–) 1.5–3 (–4) mm wide, acute, subrigid, green to grey-green or glaucous, glabrous or minutely appressed-hairy between nerves; longitudinal nerves fine, numerous and close together. Inflorescences simple, mostly 2 per axil; peduncles 1–6 (–8) mm long, ±densely silvery-white appressed puberulous and with normally sparse, red-brown glandular hairlets; heads short-obloid to cylindrical, 5–15 (–20) mm long, 4–7 mm diam., golden. Flowers 5-merous; sepals free to ¼ united, ½–⅔ length of petals. Pods straight to slightly curved, terete, (2–) 3–7 (–9) cm long, 1–2 mm wide, thinly coriaceous-crustaceous, ±obscurely longitudinally nerved. Seeds longitudinal, oblong, 3–4 mm long, shiny, brown; aril white.
Grows mostly in variously coloured sands or loam, often with a high clay content, on sandplains or flats, and on low hills and granite outcrops, in spinifex and shrubland with various Eucalyptus and Acacia species.
