Description

Acacia delicatula is an erect to ascending, often spreading shrub that typically grows to a height of up to 1.5 m (4 ft 11 in) and has finely fissured bark and terete, more or less terete branchlets. The phyllodes are arranged in clusters of up to six, linear to thread-like, straight or slightly curved, 7–13 mm (0.28–0.51 in) long and 0.2–0.5 mm (0.0079–0.0197 in) wide. The flowers are borne in one or two spherical heads in axils on a peduncle 10–15 mm (0.39–0.59 in) long, each head 4–6.5 mm (0.16–0.26 in) in diameter with 34 to 38 yellow flowers. Flowering has been recorded in January, March to May and July to August, and the pods are mostly very narrowly lance-shaped, straight sided, flat, 20–44 mm (0.79–1.73 in) long, 3–4 mm (0.12–0.16 in) wide, woody and glabrous.
