Rounded or obconic, normally multi-stemmed shrub 1–3 (–4) m tall, stems ±sparingly fluted, crowns dense and compact. New shoots densely silvery white appressed hairy. Bark smooth or finely fissured. Branchlets ±angular or sub-flattened at extremities, obscurely ribbed, glabrous or appressed-puberulous at extremities. Phyllodes narrowly oblanceolate to linear-oblanceolate, linear-elliptic or linear, flat, straight to shallowly incurved, acute or obtuse and innocuous to coarsely pungent, (4–) 5–11 (–13) cm long, (2–) 5–8 (–10) mm wide, subrigid, green to grey-green with a distinctive silvery sheen most evident on young phyllodes, appressed-puberulous with hairs confined to between nerves with age; longitudinal nerves numerous, fine and close together. Inflorescences simple, mostly 2 per axil; peduncles 3–7 mm long, with dense, silvery white appressed hairs and occasionally red-brown glandular hairlets; heads widely ellipsoid to obloid or short cylindrical, 8–12 mm long, 5–7 mm diam., golden. Flowers 5-merous; calyx variable, divided to c. ½ its length or sometimes to the base. Pods straight to slightly curved, terete, 2–5 cm long, (1.5–) 2–3 mm wide, thinly to moderately coriaceous, appressed-puberulous, obscurely longitudinally nerved. Seeds longitudinal, oblong, 2–2.5 (–3) mm long, shiny, light or dark brown; aril white.
