Phyllodes straight to shallowly incurved with apices often slightly recurved, semi-terete to compressed and linear, 4–11 mm long, 0.4–0.7 mm wide, green, glabrous, nerveless or with obscure midrib; gland inconspicuous, c. 1 mm above pulvinus. Inflorescences rudimentary 1-headed racemes with axes <0.5 mm long; peduncles 2–6 mm long, slender, glabrous; basal bracts brown; heads globular, 2–2.5 mm diam., 6- or 7-flowered, golden. Flowers 4- or 5-merous; sepals irregularly 1/4–3/4-united. Pods somewhat tightly and irregularly coiled, to 1 cm long (unexpanded), 2.5 mm wide, thinly coriaceous, glabrous. Seeds longitudinal, turgid, widely elliptic to widely ovate, obliquely truncate adjacent to aril, 2–2.5 mm long, semi-shiny, dark brown.

The illustration of A. oxyclada in J.H.Maiden, J. & Proc. Roy. Soc. New South Wales 53: pl. 12, figs 1 & 2 (1920), contains discordant elements: in pl. 12, figs 1 & 2 are A. oxyclada and figs 3–9 are A. pulviniformis . Also in J.H.Maiden, op. cit. 196, the flowers and pods described in the table are those of A. pulviniformis .
