Obconic tree 3–8 (–10) m tall sometimes with a pseudo-conifer (adolescent plants) or rarely a conifer growth form. Bark charcoal grey to blackish. Branchlets obscurely ribbed or ribless, ribs normally not resinous; new shoots not resinous, with a dense layer of dark-coloured (often blackish) glandular hairlets that persist (becoming scattered) as shoot expands and imparting a fine, granular appearance to the young phyllodes and branchlets. Phyllodes sub-straight to shallowly curved, sigmoid or wavy, narrowly linear or sometimes narrowly elliptic, not rigid, flat, 5–10 (–12) cm long, 1–3 (–5) mm wide, green to grey-green (often sub-glaucous when young), finely multistriate with obscure appressed hairs between the nerves, margins normally not resinous; gland normally 0–2 mm above pulvinus. Inflorescences simple; peduncles (4–) 5–12 (–15) mm long. Flowers 5-merous; sepals free or shortly united at base, ⅓–½ length of petals, oblong to narrowly oblong; petals 1.3–1.5 mm long. Pods oblong to narrowly oblong, mostly shallowly to moderately constricted between the seeds, (1–) 2–5 (–6.5) cm long, (6–) 8–13 mm wide including wings (when present), thinly coriaceous, commonly greyish brown but often tinged purplish, minutely appressed white-hairy, not resinous, obscurely reticulate; margins bevel-edged, rarely with wing 1 mm wide. Seeds longitudinal to oblique or transverse, 4–7 (–8) mm long, (3–) 4–6 mm wide, discoid to widely elliptic or sometimes oblong, flattened; aril small, ±white.
Grows in sand, loam or clay on stony plains or in skeletal soil on low rocky hills of mixed geology, and is commonly associated with water courses; in open to dense Mulga and/or mixed Acacia shrubland.
