Acacia ommatosperma (Pedley) Pedley, Austrobaileya 3: 216 (1990)
Shrub or small tree with pendulous branches. Branchlets apically angular, soon terete, glabrous. Phyllodes narrowly oblong-oblanceolate, incurved, 9.5–12.5 cm long, 7–14 mm wide, narrowed towards base, rounded-obtuse, coriaceous, glabrous, with 3–5 main nerves and relatively few obscure, longitudinally anastomosing minor nerves inbetween; glands 2–3 along upper margin, the lowermost 0–2 mm above pulvinus. Inflorescences simple, 1 or 2 per axil with one head of each pair maturing before the other; peduncles 3–8 mm long, glabrous; heads globular, 25–30-flowered. Flowers 5-merous; sepals 1/3-united. Pods linear, alternately raised over seeds and scarcely constricted between them, to 10 cm long, 6–8 mm wide, thinly coriaceous, glabrous. Seeds longitudinal, subcircular, 3.5 mm long, dull, dark brown; pleurogram prominent; funicle slightly thickened into a narrowly clavate aril.
Restricted to a small area of the Cape York Penin. near Weipa, Qld. Grows in ironstone gravel.
Related to A. fleckeri which has wider phyllodes and seeds encircled by a fleshy funicle/aril. Also related, less closely, to A. legnota which is most readily distinguished by its larger, falcately recurved phyllodes with more main nerves and longer peduncles. Also related to A. johannis .
