Occurs in north-eastern Qld in the Davies Ck region (SE of Mareeba), the Herberton–Watsonville area and Paluma Ra. (NW of Townsville).
Multi-stemmed, glabrous shrub 0.5–3 m high, occasionally prostrate. Branchlets glabrous. Phyllodes variable in shape and size, narrowly elliptic, oblong-elliptic, oblong-oblanceolate or linear, straight to slightly curved, (3–) 5–15 (–19) cm long, 2–12 (–15) mm wide; multinerved with central one the most prominent, the nerves 2–3 (–4) per mm, ±subdistant and very rarely a few anastomosing; gland 1, minute, to 0.5 mm above pulvinus. Spikes 1–2.5 cm long at anthesis, rather densely flowered, bright sulphur yellow; peduncles 2–5 (–7) mm long. Flowers 5-merous, also occasionally 4- or 6-merous; calyx gamosepalous, sinuate or dissected for 1/3–1/2 its length; petal midrib thickened at apex. Pods linear, straight-sided or very slightly constricted between seeds, straight or slightly curved (dehisced valves curved), flat, 4–11 cm long, (5–) 6–8 (–10) mm wide, subwoody, blackish; margins thickened, pale coloured; stipitate. Seeds longitudinal, oblong-elliptic to orbicular, 4–5.5 mm long, brown or red-brown; pleurogram with broad halo; areole closed or scarcely open, ±fawn.
Grows in open eucalypt woodland in shallow stony or rhyolitic soils, often in rugged, hilly areas.
Qld: 8 miles [12.9 km] from Paluma towards Ewan, C.H.Gittins 2415 (CANB, NSW); Davies Ck, Mareeba, H.S.McKee 9332 (NSW); Atherton, May 1919, H.W.Mocatta (NSW).
Narrowest, linear phyllode forms resemble A. guymeri and sometimes A. jackesiana. Wide phyllode forms superficially resemble A. hyaloneura which is distinguished by its hyaline phyllode nerves and interrupted, longer, paler coloured spikes.
