Phyllodes linear, flat, 1–5.5 (–7) cm long, 1–1.8 mm wide, with pungent-pointed apex, often thick, rigid; nerves commonly 3 to each face, with one prominent or, if phyllodes acicular or angular, then with 4 prominent nerves and sometimes faint nerves between them; gland obscure or absent; pulvinus absent or very short. Inflorescences with peduncles 1.5–2 (–4) mm long; spikes reduced to solitary or rarely paired clusters of 2–6 flowers less than 6 mm long; bracteoles navicular, c. 1 mm long, 0.6 mm wide.

Tas.: Royal Gorge, banks of St Pauls R., date and coll. unknown (HO); St Pauls R., near China Cup Hill, A.Moscal 811 (MEL); 10.9 km E of Campbell Town along Lake Leake Hwy to Swansea, F.E.Davies 902A & P.Ollerenshaw (MEL).


Distinguished from A. verticillata by its often longer phyllodes which are never whorled and its flowers in shortly pedunculate clusters, and from A. riceana, its closest relative, by its shorter spikes (which appear as globular heads) on shorter peduncles.
