Erect, straggly or bushy shrub or tree to 9 (–20) m high, often with pendulous branches. Bark smooth or slightly fissured, grey-brown or green. Branchlets terete, slightly angled or flattened towards apices, often pruinose, pilose with fine white-translucent hairs especially on ridges. Leaves with petiole to 0.7 cm long (sometimes obscured by basal pinnae arising from near pulvinus), mostly with a raised, circular to broadly elliptic or slightly obovate gland at base of or near lowest pair of pinnae; rachis (2.5–) 5–12 cm long, grooved above (a shallow, longitudinal groove flanked on either side by a narrow ridge, or appearing like a broad ridge with a shallow groove running down middle), pilose mostly above (with hairs mainly on the ridges either side of groove and on sides of rachis) but sometimes on both sides, with a jugary or ± jugary gland similar to the petiolar gland occurring mostly at the uppermost 1–4 pairs of pinnae (these glands sometimes occur just below to half-way down, appearing interjugary; glands are sometimes present between the uppermost 9 pairs of pinnae, often irregularly so); pinnae (6–) 10–22 (–29) pairs, (1–) 2–4 (–4.7) cm long; pinnules (12–) 20–45 (–51) pairs, oblong to narrowly oblong, (1–) 1.5–2.5 (–3) mm long (rarely to 3.5 mm long), 0.5–0.7 (–0.9) mm wide, dark green above, paler green beneath, ciliate, apex obtuse or acute. Inflorescences in terminal and axillary racemes and panicles. Peduncles (1–) 2–5 mm long, glabrous. Heads globular, c. 9–13-flowered, c. 3–5 mm diam. (when dry), pale yellow or cream-coloured. Pods straight to curved, ± submoniliform (margins usually slightly to moderately, ±regularly to irregularly constricted between seeds), ± flat but discernibly raised over seeds, to 8.5 cm long, 4–6.5 mm wide, coriaceous, brownish black or blue-black, usually ± pruinose, with few, fine lateral veins, glabrous.
Grows in clayey soils and sandy loams, on hill slopes, creek banks and roadsides, commonly with Eucalyptus beyeriana, E. punctata, E. ralla, E. tereticornis, Angophora floribunda, Acacia filicifolia, A. mearnsii, Bursaria spinosa and Olearia viscidula. In a sheltered forest in Sawpit Gully it also grows with rainforest species (K. Mills, pers. comm.). Further details on habitat are provided by Kodela (2015).
