Acacia melleodora Pedley
Acacia melleodora Pedley
Scented Wax Wattle, Waxy Wattle
Widespread and common in the N and central arid zone where it extends from the Pilbara region in W.A. eastwards through central and southern N.T. and north-western S.A. to central Qld.
Shrub 1–4 m high, glabrous, resinous, viscid. Branchlets often sparsely tuberculate. Phyllodes obovate to oblanceolate or narrowly oblong-elliptic, 1.5–4 (–5) cm long, (3–) 4–10 (–15) mm wide, l:w = 3–6, obtuse, mucronulate, coriaceous to thinly coriaceous, smooth or sparsely tuberculate, dull grey-green or glaucous, frequently with a whitish bloom (especially over the nerves) due to dry resin; with 2 or 3 prominent longitudinal nerves, with secondary nerves forming a relatively fine, open, net-like reticulum; basal gland elongate, c. 1.5 mm long, with an obscure smaller gland at base of the minute apical mucro. Inflorescences simple, 1–3 per axil; peduncles 1–2 (–3) cm long, ebracteate at base; heads globular or obloid, 5–6 (–8) mm diam. when dry, densely 30–40-flowered, golden. Flowers 5‑merous; sepals united almost to their apices. Pods stipitate, oblong to narrowly oblong, flat, raised over seeds alternately on each side, to 9 cm long, 9–11 (–15) mm wide, firmly chartaceous, often ±vernicose; stipitate. Seeds transverse, c. 4 mm long, arillate.
Grows in deep red or red-brown siliceous sand, on dunes or interdunal areas; sometimes found on shallow stony soils.

Acacia melleodora, A. jensenii and A. sabulosa may ultimately prove to be better placed as infraspecific taxa of A. dictyophleba. Acacia jensenii and A. sabulosa are most readily distinguished from both A. dictyophleba and A. melleodora by their generally more elongate and predominantly 1-nerved phyllodes. Acacia melleodora is especially close to A. dictyophleba and in W.A. at least some intermediates appear to occur.
Can resprout from the base following fire although in most instances it is killed.
For Aboriginal use of A. melleodora in central Australia, refer to the discussion of A. dictyophleba in P.Latz, Bushfires & Bushtucker 96 (1995); it is probable that most of the information contained in this account refers to A. melleodora.
Phyllodes sometimes resemble those of which is distinguished by its generally hairy branchlets and pods, shorter peduncles with a persistent basal bract and longitudinal seeds. Acacia praemorsa and sometimes A. johnsonii also have an apical gland on the phyllode apex. . Narrow phyllode forms may superficially resemble A. orthotropica from Kimberley region, W.A., but the two species probably not especially closely related.
