Spindly shrub or slender tree to c. 6 m high. Upper branches often pruinose. Branchlets dark reddish, often pruinose, glabrous. Phyllodes obliquely obovate to narrowly elliptic, curved near the much-narrowed base, 9–22 cm long, 25–80 (–160) mm wide, obtuse, usually glaucous, glabrous; midrib prominent and ±excentric; minor veins forming an open reticulum; gland 0–4 mm above pulvinus, with pore narrow and elongated (often slit-like), and 1–3 additional glands on triangular projections sometimes present; pulvinus 5–12 mm long. Inflorescences racemose, sometimes paniculate; raceme axes 3–8 cm long, sometimes longer, glabrous, sometimes appressed-puberulous; peduncles 4–8 mm long, glabrous, sometimes appressed-puberulous; heads globular, 25–40-flowered, pale lemon yellow or golden. Flowers 5‑merous; sepals c. ⅚-united. Pods to 22 cm long, 9–15 mm wide, thinly coriaceous, slightly pruinose, glabrous. Seeds longitudinal, oblong to elliptic, 6–9 mm long, ±dull, black; funicle encircling seed in a single fold, thick, reddish brown; aril linear-clavate.
Usually grows in shallow soil on rocky hillsides in Eucalyptus woodland or open forest. Near Kingaroy it occurs in deep alluvium and its foliage is then usually green, according to L. Pedley, Austrobaileya 1: 265 (1980).
