Acacia deuteroneura Pedley




Known only from the type locality, Qld.


Shrub to c. 3 m high. Branchlets pruinose, glabrous. Phyllodes narrowly elliptic to oblong-elliptic or ±oblanceolate, 3–6 cm long, 6–12 mm wide, obtuse, coriaceous, glaucous, glabrous; midrib prominent, with a minor nerve parallel to midrib for 2/3 length of phyllode; lateral nerves few and obscure; gland somewhat prominent, 10–18 mm above pulvinus, occasionally a second gland above middle. Inflorescences racemose; raceme axes 3–5 cm long, pruinose, glabrous; peduncles 10–16 mm long, pruinose, glabrous; heads globular, 20–30-flowered, yellow. Flowers 5-merous; sepals c. 3/5-united. Pods to c. 5 cm long, 12–13 mm wide, firmly chartaceous, pruinose, glabrous. Seeds transverse, oblong-elliptic, 3.5–4 mm long, ±dull, black; funicle 3/4 encircling seed in a double fold; aril clavate.


It grows with Eucalyptus bakeri on a knoll of weathered sandstone.


Qld: 60 km N of Tambo, L.Pedley 4111 (BRI, NSW).


A member of the ‘A. microbotrya group’ and superficially resembling A. wattsiana (S.A.). In the field A. deuteroneura may be confused with A. decora and A. polifolia which are common in the same area, but the latter two species are readily distinguished by their 1-nerved phyllodes, hairy racemes and peduncles, and funicles which do not encircle the seeds.
