Acacia prominens A.Cunn. ex Don, Gen. Hist. 2: 406 (1832)

Gosford Wattle , Golden Rain Wattle , Grey Sally and others

Dense shrub or tree 5–9 m high, sometimes 20–25 m high. Branchlets slender, angled at extremities, glabrous. Phyllodes narrowly elliptic to narrowly oblong-elliptic, 3–6 cm long, 5–12 mm wide, l:w = 4–9, normally obtuse-mucronulate to subacute, thin, grey-green to glaucous, glabrous except pulvinus sparsely hairy, 1-nerved per face, finely penninerved; gland prominent, normally exserted, 5–20 mm above pulvinus. Inflorescences racemose; raceme axes 1.5–6 cm long, slender, glabrous; peduncles 5–7 mm long, slender, glabrous; heads showy, globular, 7–16-flowered, lemon yellow. Flowers 5-merous; sepals united; ovary glabrous. Pods stipitate, to 10 cm long, 9–12 mm wide, firmly chartaceous, pruinose, glabrous. Seeds mostly longitudinal, oblong to elliptic, 5–6 mm long, shiny, black; aril clavate.

Confined to creek banks and forests of near coastal areas from Gosford to near Singleton, N.S.W.

Confusion surrounding the name A. prominens , A. fimbriata and A. linifolia was discussed by J.H.Maiden, Forest Fl. New South Wales 5: 29- 34 (1911), and V.S. Summerhayes, Bot. Mag . 155: t. 9256 (1931). The description of A. prominens in G. Bentham, Fl. Austral. 2: 371 (1864) included elements of A. fimbriata .

Related to A. kettlewelliae which is distinguished especially by its generally longer or narrower phyllodes (l:w normally 8–13), glands submerged within the lamina and shorter peduncles. Also related to A. covenyi .
