Acacia meiosperma (Pedley) Pedley, Austrobaileya 3: 216 (1990)
Shrub or tree 2–3 m high, pubescent when young. Branchlets angular and resinous at extremities, usually glabrous. Phyllodes inequilaterally narrowly elliptic, straight or shallowly falcately recurved, , 7–12.5 cm long, mostly 2–3 cm wide, usually glabrous, resinous when young, with numerous, fine, close and nonanastomosing veins, of which 3–5 are more prominent; pulvinus 5–10 mm long. Inflorescences initiated synchronously with phyllodes on new shoots, 1–4 per axil, rarely in short racemes; peduncles 3–5 mm long, densely hairy, the basal bract brown and caducous; spikes 1.5–3.5 cm long, golden. Flowers 5-merous; sepals free to 1/4 united; ovary often absent, densely hairy. Pods linear-compressed, to 8 cm long, 3 mm wide, coriaceous, obscurely longitudinally ribbed, glabrous. Seeds longitudinal, oblong, 3–4 mm long, glossy, dark brown except yellow at centre; funicle-aril folded, creamy white.
Confined to a small area c. 40 km SE of Chillagoe, Qld, where it forms pure stands in shallow stony soil.
Young plants are pubescent and long hairs persist on branches and phyllodes of some mature plants.According to L.Pedley, Austrobaileya 3: 216 (1990), the resemblance of this species to A. brassii may not indicate a close relationship; its inflorescence structure suggests a relationship with A. julifera , A. blakei and other species with spikes arranged in racemes. In the absence of pods, specimens with falcate phyllodes (e.g. Clarkson 2988, cited below) may resemble A. crassicarpa which is readily distinguished by its glabrous peduncles.
