Description

Acacia daviesioides is an intricate, glabrous shrub that typically grows to a height of 0.3–1 m (1 ft 0 in – 3 ft 3 in) and has many straight, more or less glaucous branches. Its phyllodes are linear, rigid, spiny and continuous with the branchlets, more or less glaucous, 2–10 mm (0.079–0.394 in) long and narrowed near the tip. There are linear stipules 1–3 mm (0.039–0.118 in) long at the base of the phyllodes. The flowers are borne in spherical heads in up to 3 racemes on peduncles 3–10 mm (0.12–0.39 in) long, the heads with 15 to 24 light golden yellow flowers. Flowering occurs from June to September, and the pods are linear, up to 80 mm (3.1 in) long and 3–5 mm (0.12–0.20 in) wide and leathery to crusty with broadly oblong to oblong seeds 2.5–3.0 mm (0.098–0.118 in) long with a large aril.
