Acacia simsii A.Cunn. ex Benth.

Shrub or small tree, 7 m high, bole 1-2 m, 2-10 cm d.b.h. Branchlets slender, angular, glabrous, sometimes with conspicuous lenticels. Stipules subpersistent, triangular, up to 1 mm. Phyllodes rather membranous, glabrous, punctu-late, sometimes papillose on the margins, straight or curved, linear, tapering at both ends, acute or apiculate, 5-ll(-14) by 0.2-0.9 cm, 13-33(-50) times as long as wide, light green to dark green, major veins and margins not yellowish; pulvinus 1-2 mm, with a gland at base of phyllode, circular, not conspicuous, 0.2-0.4 mm in diameter and with 1-5 similar glands along the margin; longitudinal veins numerous, of which 1-3 more prominent than the others, widely spaced, obscure when phyllodes are narrow, anastomoses hardly visible. Glomerules c 4 mm in diameter, aggregated into condensed racemes, in 2 pairs, one of each pair maturing before the other, on glabrous peduncles, 0.5-0.8 cm. Flowers golden yellow, pentamerous. Calyx membranous, 0.6-0.8(-1) mm, lobes rounded or obtuse, 0.2-0.3 mm, fimbriate. Corolla 13-1.5 mm, separating completely or to about the middle into elliptic lobes. Stamens c. 3 mm. Ovary sessile, glabrous. Pod glaucous, brown, linear, flat, with nerve-like margins, raised over the seeds alternately on each side, 5-8 by 0.4-0.5 (-0.7) cm. Seeds longitudinal, broadly elliptic, 3-4 by c. 3 mm, c. 1.5 mm thick; areole oblong, c. 2 by 1 mm, closed or open, funicle ± straight to form a clavate aril below the seed.

Usually grows in sand and gravel in eucalypt open forest and woodland, sometimes in closed heath on Cape York Peninsula and sometimes forming closed scrub in disturbed areas. Found on gentle slopes and plains in coastal areas and inland on gently undulating terrain.

Can be grown by seedlings. Seeds needs soaking.
