Acacia guinetii

Acacia guinetii is a spreading shrub that typically grows to a height of 0.3–1 m (1 ft 0 in – 3 ft 3 in) or a spindly shrub to about 2 m (6 ft 7 in) and has hairy branchlets that commonly arch downwards. It has a single pair of pinnae 4–10 mm (0.16–0.39 in) long on a petiole 1.0–1.5 mm (0.039–0.059 in) long. Each pinna usually has three or four pairs of pinnules 4–7 mm (0.16–0.28 in) long, 1–2 mm (0.039–0.079 in) wide and green with the edges turned down or rolled under. There is a sessile gland on the petiole at the base of the pinnae and sometimes at the base of the lowermost pair of pinnules. The flowers are borne in one or two spherical heads in leaf axils on a peduncle 10–25 mm (0.39–0.98 in) long and usually much longer then the leaves. Each head has 50 to 75 densely arranged golden yellow flowers. Flowering occurs from June to September and the pods are 20–40 mm (0.79–1.57 in) long and 3–4 mm (0.12–0.16 in) wide with oblong seeds 2.5–3.0 mm (0.098–0.118 in) long. This species belongs to the Acacia pulchella group of wattles and resembles Acacia lasiocarpa.

Guinet's wattle grows on lateritic hills in heath between Geraldton and Northamton in the Geraldton Sandplains bioregion of southwestern Western Australia.
