Acacia aprepta Pedley, Contr. Queensland Herb . 15: 5 (1974)
Spreading tree to 10 m high. Bark longitudinally furrowed, dark grey or black. Branchlets angular, becoming terete, light brown to greyish, glabrous, slightly resinous or resinous-scurfy especially when young. Phyllodes linear or very narrowly oblanceolate, flat, straight or slightly subfalcate, 3.5–8.5 cm long, (2–)3–8 mm wide, coriaceous, olive green, scurfy, resinous when young, with 1–3 longitudinal veins more prominent and 8–12 minor veins per mm; basal gland inconspicuous. Spikes 1–3 in phyllode axils, 0.6–3.5 cm long, yellow. Flowers 5-merous; calyx 0.4–0.5 mm long, dissected to 1/5–1/4, glabrous or sericeous on ribs, pubescent at base; corolla c. 1.5 mm long, cut to 1/2, glabrous, scurfy; ovary glabrous. Pods linear or very narrowly oblong, raised over seeds on alternating sides, 2.5–6 cm long, 5–9 mm wide, chartaceous, light brown, glabrous, scurfy, slightly viscid. Seeds oblique, broadly oblong, 2.3–3.5 mm long, dark brown with an often paler small areole; pleurogram U-shaped, usually with pale halo.
Occurs in south-eastern Qld between 148E and 151E, in the western areas of the Darling Downs, and Maranoa districts. Grows in thickets or in dense populations in shallow gravelly or sandy loam soils, over sandstone (see L.Pedley, Austrobaileya 1: 159 1978). Flowers mostly Oct.–Jan. Fruits Dec.
According to L.Pedley, loc. cit ., A. aprepta appears similar to A. aneura in the field, and has morphological affinities to A. stowardii and A. kempeana .
