Munumula , Balkura , Gurley , Gooralee , Ironwood , Dalby Wattle , River Cooba , River Myall , Belalei , Eumong , Native Willow , Black Wattle , Dunthy

Somewhat bushy tree 4–20 m high, with a tendency to sucker. Bark rough, dark grey to blackish. Branchlets normally pendulous, glabrous to sericeous. Phyllodes ligulate, pendulous, 15–40 cm long, 2–7 mm wide, innocuous with an acute to acuminate, often curved apex, coriaceous, rather lax, glabrous or sparsely appressed-puberulous, with numerous subdistant nerves. Inflorescences (1- ) 2–6-headed racemes; raceme axes (1- ) 3–5 (- 15) mm long, appressed-puberulous, rarely glabrous; peduncles 6–13 mm long, with indumentum as on raceme axes; heads globular, 6–9 mm diam., (20- ) 25–40-flowered, creamy white to pale yellow. Flowers 5-merous; sepals 3/4-united. Pods moniliform, breaking readily at constrictions, 10–26 cm long, (6- ) 8–12 mm wide, woody, obscurely longitudinally wrinkled, glabrous. Seeds longitudinal, broadly elliptic to oblong-elliptic, 7–9 mm long, dark brown; funicle scarcely arillate.

Very widely distributed in inland arid areas from north-eastern W.A., E through N.T. to Qld (W of the Great Divide) and S to the Murray- Lachlan- Darling R. system in N.S.W., Vic. and S.A., disjunct in S.A. between L. Eyre and the Murray R. Usually grows in heavy soils along watercourses subject to periodic flooding where it frequently forms monospecific stands.

The long phyllodes and growth habit resemble A. coriacea .
