Acacia amentifera is a shrub which grows to a height of up to 3 m (9.8 ft) and has arching branchlets. Its phyllodes are arranged in clusters of usually 3 to 5 in nodes, oblong and curved upwards, 6–11 mm (0.24–0.43 in) long and 1–2.5 mm (0.039–0.098 in) wide and finely wrinkled. The flowers are golden yellow and arranged in spikes 5–10 mm (0.20–0.39 in) long. Flowering has been observed in January and October and the fruit is a more or less linear pod up to 47 mm (1.9 in) long and about 4 mm (0.16 in) wide.[2][3]
