Acacia floribunda (Vent.) Willd., Sp. Pl . 4: 1051 (1806)
Spreading shrub or tree, 2–8 m high, 2–15 m wide. Branches commonly pendulous, angular, often pubescent. Stipules inconspicuous or absent. Phyllodes linear to narrowly lanceolate, 5–19 cm long, 1.5–12 mm wide, acute and often mucronulate, thin and pliable, with 1–3 primary veins, the secondary veins 6–10, parallel, anastomosing; gland absent; pulvinus present. Inflorescences with very short peduncles; spikes solitary or twinned, interrupted, 2–8 cm long; bracteoles absent or if present then deltoid and less than 0.5 mm long. Flowers loosely packed, 4-merous; sepals united. Pods subcylindrical, constricted between seeds, mostly straight, 6–12 cm long, 2–4 mm wide, chartaceous. Seeds elliptic, 3–5 mm long, glossy, brown; funicle folded about 4–8 times; aril small, irregularly thickened.
Widespread in forests and woodlands along the eastern coastal and subcoastal regions from Stanthorpe, Mt Barney and Tambourine Mt in SE Qld, southwards through N.S.W. to Briagolong N of Stratford in eastern Vic. with an isolated occurrence at Nambour near Maroochydore in south-eastern Qld. It is often common along the banks of streams.
Easily distinguished by the absence of glands on the phyllodes, and the thin and mostly pliable phyllodes. Acacia floribunda apparently hybridises with A. oxycedrus .
