Rounded, multi-stemmed shrub commonly 1.5–3 m tall, maturing to tree 4–5 (–7) m, crown often compact. Branchlet ribs with a thick layer of opaque, segmented, milky blue-grey or yellowish resin that often persists as beaded white lines on mature branchlets; new shoots very resinous, reddish glandular hairlets embedded within the opaque resin. Phyllodes variable, symmetrically elliptic to narrowly elliptic or obovate to oblanceolate, often slightly twisted or shallowly undulate, straight, (1–) 2–5 cm long, 5–10 (–13) mm wide, normally obtuse, grey, blue-grey, sub-glaucous or pale grey-green, dull green on oldest phyllodes, longitudinal nerves numerous, marginal nerve resinous and yellow to light brown. Inflorescences simple or occasionally rudimentary racemes to c. 2 mm long; peduncles 3–10 mm long, sparsely appressed white-puberulous with some red-brown, microscopic glandular hairlets; spikes 10–20 mm long; bracteoles minute (0.4–0.5 mm long) and sub-sessile. Flowers 5-merous; sepals often extremely reduced, ⅙–⅓ length of petals, ±free; petals 1.2–1.3 mm long. Pods oblong or fusiform, (1–) 1.5–3.5 cm long, (5–) 6–10 (–11) mm wide including wings 1–1.5 mm wide, firmly chartaceous to thinly coriaceous, dark greyish brown, obscurely longitudinally reticulate. Seeds oblique or sometimes longitudinal, 4.5–5.5 mm long, 2.5–3.5 mm wide, elliptic; aril small, creamy white.
Grows in red-brown loam, sandy loam, silty loam, clay-loam or sometimes clay often over hardpan, on flats, gently undulating country or in skeletal soil on rocky hills. Often found in mixed Mulga shrubland with a ground cover of Spinifex (Triodia sp.).
