Acacia acrionastes Pedley, Austrobaileya 3: 297; 298, map 1 & 299, fig. 1 (1990)

Spindly, glabrous shrub or tree 2–8 m high. Phyllodes linear, mostly 9–12.5 cm long, 2–5 mm wide, often gradually narrowed towards apex, thin, smooth or very finely wrinkled when dry, 1-nerved per face; lateral nerves obscure or absent; gland not or scarcely exserted beyond margin, commonly 1–2.5 cm above pulvinus. Inflorescences 10–16-headed racemes; raceme axes 2–4.5 cm long; peduncles 3–6 mm long; heads globular, 12–16-flowered, creamy yellow. Flowers 5-merous; sepals united into a truncate calyx. Pods to 10 cm long, 8–10 mm wide, thinly coriaceous. Seeds longitudinal, elliptic, 4.5–5 mm long, shiny, black; aril clavate.

Geographically restricted in south-eastern Qld where it occurs on Mts Barney, French, Gillies and Maroon. Grows in Eucalyptus forest in shallow rocky soil derived from rhyolite or basalt and in heath among rocks on mountain peaks, to 1200 m alt.

Most closely related to A. floydii which has slightly narrower phyllodes with more prominent glands nearer the base and fewer flowers per head. Formerly confounded with A. adunca which has bright golden flower-heads and uncinate, thicker, generally narrower phyllodes. Phyllodes resembling those of A. macnuttiana .
