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, 2.5–6 cm long, 4–12 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, (3–) 5–20 mm above pulvinus. Inflorescences racemose; raceme axes 1.5–8 cm long, slender, glabrous; peduncles 3–7 mm long, slender, glabrous; heads showy, globular, 7–16-flowered, pale yellow to lemon yellow.

N.S.W.: Darkey Ck, Putty–Singleton road, 9 Sept. 1948, E.F.Constable s.n. (NSW, MO); Oatley, Aug. 1888, J.H.Maiden (NSW); Narara, West Gosford, 18 Jan. 1906, A.Murphy s.n. (NSW).


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.
