Shrub to 1 (–2) m high, erect or prostrate, resinous, branching near ground. Bark smooth, dark grey to dark brown. Branchlets angular, brown to dark red-brown or yellowish, glabrous; ridges often minutely resin-crenulated. Phyllodes very narrowly elliptic, narrowly elliptic-oblong to linear, straight to slightly curved, 1.5–4.5 cm long, 1.4–5.2 mm wide, thinly coriaceous, with prominent stomata, with 1 ± prominent main vein and sometimes 2 ± subprominent veins; minor veins indistinct, parallel, sometimes sparingly ± anastomosing; gland basal, inconspicuous, 1–2 mm above pulvinus. Heads 3–4.5 mm diam., yellow. Flowers 10–13 per head, 5-merous; calyx 0.9–1.1 mm long, almost free, glabrous; corolla 1.4–1.6 mm long, dissected to 1/3–1/2, glabrous; ovary glabrous. Pods oblanceolate to narrowly oblanceolate, basally narrowed, straight-sided, flat, 2–5 cm long, 4–9 mm wide, thinly woody, obliquely striate; margins and seed-partitions prominent. Seeds oblique, oblong-elliptic, 2.5–3.5 mm long, brown to dark brown; pleurogram with halo; areole elongate, open, dark brown; funicle-aril narrowly turbinate.
Grows usually in grey sandy podsols on stony sandstone ridges and gorges, in eucalypt forest or woodland, and on laterite and bauxite.
