Single-stemmed shrub or tree to 9 (–13) m high. Bark flaky or fissured, grey to black. Branchlets ±angular towards apices, yellowish to brown, glabrous, often resinous. Phyllodes linear to very narrowly elliptic, flat, straight or curved, 9–26 cm long, 1.5–14 mm wide, thinly coriaceous, glabrous or with appressed hairs on nerves and margins, often resinous, with midvein and 2 secondary veins more prominent; minor veins 4–7 per mm, parallel, rarely anastomosing; gland 1, basal, inconspicuous. Spikes 1–3 per axil, (1.5–) 3–8 cm long, yellow. Flowers 5-merous; calyx 0.5–0.8 mm long, dissected ±to base, with few hairs; corolla 0.9–1.2 mm long, dissected to ½, glabrous or with sparse hyaline hairs mainly on tube; ovary densely pubescent. Pods linear to cultrate, straight, undulate, raised over seeds alternately on each side, 3–12 mm wide, brown, obscurely reticulate, resinous. Seeds oblique or transverse, broadly elliptic to ±orbicular, 1.8–3.8 mm wide, dark brown; pleurogram with pale halo; areole closed, depressed, sometimes paler than rest of seed.
