Inflorescences 2 in axil of phyllodes; peduncles 1–3 mm long, hairy or glabrous; heads cylindrical, 3–8 cm long, pale yellow to ± white; flowers scattered on rachis.
Pods straight to strongly curved, raised over and constricted between seeds, mostly 6–12 cm long, 2–4 mm wide, firmly papery, longitudinally ridged, appressed-hairy to glabrous; seeds longitudinal; funicle short and expanded into an aril.

The name refers to its floriferous or free-flowering nature. A rather variable species particularly in phyllode width and hairiness. May be confused with Acacia longissima, which has longer and narrower glabrous phyllodes and A. maidenii, which usually has yellowish-hairy peduncles. Commonly cultivated.
