Acacia barattensis J.M.Black, Trans. & Proc. Roy. Soc. S. Australia 56: 42; t. 1, fig. 2 (1932)
Diffuse, viscid, glabrous shrub 2- 3 m high. Branchlets slender, commonly covered with a black sooty substance. Phyllodes erect, slender, narrowly linear, mostly shallowly incurved, compressed, 5–10 cm long, 1–1.5 mm wide, uncinate, with a strong resin odour, obscurely 3-nerved per face; gland 1–2 mm above pulvinus. Inflorescences simple, 1 or 2 per axil; peduncles 8–13 mm long; basal bract c. 0.5 mm long; heads globular, 20–30- flowered, pale yellow. Flowers 4-merous; sepals c. 3/4-united, the lobes triangular. Pods linear, constricted between seeds, to 15 cm long, 2.5–3.5 mm wide. Seeds longitudinal, oblong-elliptic, 4.5 mm long; funicle folded; aril thick.
Restricted in the Flinders Ra., S.A. Occurs in skeletal soil between outcropping quartzite on slopes of rocky gulleys and along creeklines, in association with Eucalyptus flindersii, E. camaldulensis and Callitris glaucophylla . A rare species which, until recently, was thought to be extinct.
This species is fully described and discussed by M.D.Crisp, Trans. & Proc. Roy. Soc. S. Australia 100: 117 (1976) . Distinguished from other members of the ‘ A. wilhelmiana group’ by its 4-merous flowers. Acacia gracilifolia has similarly long, narrow phyllodes.
