Acacia auriculiformis

Description

Acacia auriculiformis is a tree that typically grows to 8–10 m (26–33 ft) high, rarely up to 35 m (115 ft), and is mostly glabrous, with smooth bark or fissured bark on older trees, and thin branchlets. The phyllodes are very narrowly elliptic, sometimes curved, mostly 100–200 mm (3.9–7.9 in) long and 12–40 mm (0.47–1.57 in) wide with many longitudinal veins, three to five more prominent than the rest. The flowers are bright yellow to golden-yellow, arranged in one to several spikes in leaf axils, each spike 50–85 mm (2.0–3.3 in) long on a peduncle 4–8 mm (0.16–0.31 in) long. Flowering occurs from February to August, and the fruit is a strongly curved or spirally coiled, sometimes twisted, thickly leathery to woody pod about 50–80 mm (2.0–3.1 in) long and 10–18 mm (0.39–0.71 in) wide, containing flattened, dark brown to black seeds 4–6 mm (0.16–0.24 in) long and 3–4 mm (0.12–0.16 in) wide with an orange, yellow or red aril.
