Description

Slender shrub 1–4 m high. Branchlets ±angled, ribbed, pubescent. Phyllodes ascending, mostly narrowly elliptic, straight to slightly incurved, 6.5–15 cm long, 4.5–13 mm wide, acute, mucronulate, coriaceous, glabrous except puberulous at base and on pulvinus, with numerous distant main nerves (commonly 3 slightly more evident than the rest), ±sparingly longitudinally reticulate; gland single, c. 4 mm above pulvinus. Inflorescences 1–3-headed racemes, sometimes appearing simple; raceme axes (0.5–) 1–6 (–10) mm long, pubescent; peduncles 7–16 mm long, puberulous; heads globular, 7–9 mm diam., 30–40-flowered, creamy white; bracteoles shortly stipitate, oblanceolate-spathulate. Flowers 5‑merous; sepals 2/3-united. Pods narrowly oblong, raised over seeds alternately on each side, straight, to 8.5 cm long, 6–8 (–9.5) mm wide, coriaceous, puberulous except margins. Seeds longitudinal, broadly oblong-elliptic, 5–5.5 mm long, dull, dark brown; funicle/aril thick, fleshy, in 2 or 3 terminal folds.

Specimens

Qld: Lowood, H.Boyd (NSW107625). N.S.W.: Pacific Hwy, 20 km S of Woodburn, I.B.Armitage 1364 (BRI, NSW, PERTH); New Italy, W.Baeuerlen (NSW222583); Yuraygir Natl Park, 12 km W of Wilsons Headland, S.Griffith 022 (NSW).

Notes

Related to A. venulosa which is most readily distinguished by its generally shorter phyllodes and peduncles, golden flower-heads and spathulate bracteoles with the blade concave. May be confused with A. tessellata which has ±glabrous peduncles and pods. Also similar to A. veronica.
