Phyllodes linear, straight to shallowly recurved, 7–11 (–15) cm long, 2–4.5 (–6) mm wide, arcuate-acuminate, densely silvery white appressed-puberulous (the hairs confined to between the nerves with age), with numerous closely parallel, fine nerves. Inflorescences 2–10-headed racemes; raceme axes 1–8 mm long, densely appressed-puberulous; peduncles 4–12 mm long, densely appressed-puberulous, the hairs pale yellow ageing white; heads globular, 4.5 mm diam., 20–35-flowered, golden. Flowers 5-merous; sepals at least 3/4-united. Pods linear, straight-edged, flat, scarcely raised over seeds, to 6.5 cm long, 5–6 mm wide, coriaceous, densely silvery appressed-puberulous; marginal nerve evident. Seeds longitudinal, 5.5 mm long; aril small.
Disjunct, occurring on Brunchilly and Benmara Stns, Barkly Tableland, N.T., and also in central Qld, mostly W of the Great Divide, from Einasleigh S to near Cunnamulla, but reaching the coast near Bowen. Grows mainly in heavier soils, including alkaline and saline clays, in tall open woodland and, in drier areas, low woodland and shrubland.
