Description

Acacia filipes is spreading shrub that typically grows to a height of 1 metre (3 ft) and a width of around 2 m (6 ft 7 in). It has slender, angular branchlets that are ribbed and resinous. Its phyllodes are glabrous, 85–150 mm (3.3–5.9 in) long and 0.4–0.8 mm (0.016–0.031 in) in diameter with a short point on the end, eight parallel, longitudinal veins and a gland up to 5 mm (0.20 in) from the base of the phyllode. The flowers are borne in two spikes 10–25 mm (0.39–0.98 in) long on a slender peduncle 10–45 mm (0.39–1.77 in) long in axils. Flowering has been observed in February and the pods are flat, linear, 4.0–4.5 mm (0.16–0.18 in) long and 2–3 mm (0.079–0.118 in) wide, slightly resinous and woody. The seeds are dark grey, about 3 mm (0.12 in) long and 1.5 mm (0.059 in) wide with a cup-shaped aril. [2] [3] [4] [5]
