Shrub or tree 0.5–5 m high, prostrate in exposed coastal areas, rounded, resinous. Bark smooth or flaky, grey to brown. Branchlets angular towards apices, with reddish brown granules. Phyllodes narrowly elliptic to elliptic or sometimes narrowly oblanceolate, straight or curved, 6–15 cm long, (5–) 7–24 mm wide, chartaceous to subcoriaceous, glabrous or hoary, with 3–5 prominent longitudinal veins of which lower 2 often confluent with margin near base, sometimes 2 or 3 semiprominent parallel veins; minor veins 3–6 per mm, sometimes sparingly anastomosing; gland 1, ±inconspicuous, 2–7.5 mm above pulvinus. Spikes up to 5 in axils, 2.5–8 cm long, loosely flowered, pale yellow to cream-coloured. Flowers 5-merous, rarely 4-merous, delicate; calyx membranous, 0.4–0.6 mm long, dissected to ⅕–⅓, glabrous or with reddish brown granules towards sepal apices; corolla 0.9–1.1 mm long, dissected to ½–⅔, glabrous; ovary glabrous. Pods erect, very narrowly oblanceolate to linear, basally narrowed, flat, straight-sided, 5–11 cm long, 4.5–10 mm wide, woody, glabrous, obliquely reticulately nerved, curling upwards from apex after dehiscence; seed partitions and margins thick. Seeds oblique, oblong-elliptic, 4–7 mm long, brown; areole narrowly oblong, open; funicle-aril narrowly conical.
