Acacia burdekensis Pedley, Austrobaileya 5(2): 313 (1999)
Trees to 9 m tall; branchlets reddish, angular, scurfy, resinous (as are young phyllodes). Phyllodes straight to strongly falcate, widest below the middle, tapered to acute apices, (7) 9.5–14.5 cm long, 7–18 mm wide, glabrous; longitudinal nerves parallel and rather crowded (3–4 per mm), 2 or 3 more prominent than the rest, anastomoses few; pulvinus 4–6 mm long, reddish; gland basal, prominent with distinct swelling and an obvious orifice. Inflorescences simple; spikes 25–40 (–60) mm long, moderately dense; peduncles 7–12 mm long. Flowers 5-merous; calyx gamosepalous, cupular 0.5–0.75 mm long, glabrous except for a few minute trichomes on margins of lobes; ovary white-hirsute. Pods and seeds not seen.
Largely confined to the northern part of the Burdekin R. basin between c. 1830’S and 21S, Qld, where it occurs on stony and sandy soils on hillsides and on creek banks.
Acacia burdekensis has been previously included in a rather heterogeneous A. leiocalyx but differs in being a moderately large tree with rather elongate phyllodes similar in shape to those of A. leptostachya with fine crowded, only sparingly anastomosing, secondary nerves.
