Acacia tingoorensis Pedley




Restricted to near Kingaroy and Mt Garnet, Qld.


Tree 3–8 m tall. Branchlets stout, acutely angled towards apices, velvety by dense, short, soft patent hairs. Phyllodes dimidiate to shallowly or obviously falcately recurved, 10–18 (–23) cm long, (10–) 15–35 mm wide, coriaceous, green, multistriate with 3 or 4 nerves more pronounced than the rest and free to the base or the lower 2 confluent near the pulvinus but free from lower margin, the minor nerves sub-distant (mostly 3–4 per mm), longitudinally anastomosing secondary nerves relatively few to sub-numerous, velvety or more commonly glabrous; pulvinus 2–5 (–8) mm long, commonly densely hairy and indistinct. Inflorescences simple or rudimentary racemes to 1 mm long, mostly 2 per axil; spike 4–8 (10) cm long, golden, the flowers sub-dense or somewhat widely spaced in the spikes; axis of spike glabrous or velvety hairy; peduncles (2–) 5–10, hairy. Flowers 5 merous. Calyx very shortly dissected, with indumentum sometimes only at the base; ovary densely pubescent. Pods sub-moniliform, to c. 6 cm long, 3–4 mm wide, straight to shallowly curved, rounded over seeds and moderately constricted between them, glabrous. Seeds longitudinal, oblong, 4 mm long, 2 mm wide, dark brown; aril terminal and yellow (at least when dry).


Flowers Aug.–Sept.
