Acacia mearnsii, commonly known as black wattle, late black wattle or green wattle, is a species of flowering plant in the family Fabaceae and is endemic to south-eastern Australia. It is usually an erect tree with smooth bark, bipinnate leaves and spherical heads of fragrant pale yellow or cream-coloured flowers followed by black to reddish brown pods. In some other parts of the world, it is regarded as an invasive species.
Acacis mearnsii is a spreading shrub or erect tree that typically grows to a height of 10 m (33 ft) and has smooth bark, sometimes corrugated at the base of old specimens. The leaves are bipinnate with 7 to 31 pairs of pinnae, each with 25 to 78 pairs of pinnules. There is a spherical gland up to 8 mm (0.31 in) below the lowest pair of pinnae. The scented flowers are arranged in spherical heads of twenty to forty and are pale yellow or cream-coloured, the heads on hairy peduncles 2–8 mm (0.079–0.315 in) long. Flowering mainly occurs from October to December and black to reddish-brown pods, 30–150 mm (1.2–5.9 in) long and 4.5–8 mm (0.18–0.31 in) wide develop from October to February.
