Shrub or tree 3–13, sometimes 20 m high in N.S.W., often clonal due to suckering habit. Branchlets pendulous, dark grey-brown, glabrous. Phyllodes pendulous, variable, linear to narrowly oblanceolate or narrowly elliptic, 7–20 cm long, 4–30 mm wide, l:w = 4–40, flaccid, green to grey-green, sometimes glaucous, glabrous, 1-nerved, penninerved; glands 2–5, lowermost 0–5 mm above pulvinus, distal glands often prominent with one at base of mucro. Inflorescences 2–8-headed racemes; raceme axes 1–5 cm long, glabrous, rarely appressed-puberulous; peduncles 5–15 mm long, glabrous; heads globular, subdense, 15–25-flowered, cream to pale yellow. Flowers 5-merous; sepals united into a truncate calyx. Pods narrowly oblong, to 12 cm long, 7–13 mm wide, woody, thick, longitudinally striate when dry, grey-green, glabrous. Seeds longitudinal, elliptic to oblong-elliptic, 4.5–6 mm long, shiny, dark brown to black; aril scarlet.
Widespread in eastern Australia, predominantly in central Qld and western N.S.W., but extending to N.T., S.A. and Vic.; possibly also W.A. (see below). Grows mostly along water courses and on floodplains, in soils ranging from sand to clay. For full discussion of habitat and of uses, see J.W.Turnbull (ed.), Multipurpose Austral. Trees Shrubs 192 (1986). Flowers irregularly throughout the year with peak appearing to be Apr.-June.
A member of the ‘ A. bivenosa group’ which in the past was often confused with A. ligulata and A. ampliceps , see A.R.Chapman & B.R.Maslin, Nuytsia 8: 249–283 (1992) for review. It is distinguished most readily from A. ligulata by its pendulous phyllodes and cream to pale yellow heads and from A. ampliceps by its fewer-flowered, cream to pale yellow flower-heads and broader pods.
A flowering collection ( I.J.Mason LAC 5279, A n.v., CANB, BRI n.v., L n.v., P n.v., PERTH, RSA n.v.) from 20 km W of Wiluna, W.A., appears to be A. salicina but pods are needed to confirm the identification; the species is otherwise not known to occur in W.A.
