English: Boomerang Wattle

Acacia amoena, commonly known as boomerang wattle,[1][2] is a shrub belonging to the genus Acacia and the subgenus Phyllodineae that is native to parts of eastern Australia.


The shrub has an erect to spreading habit and typically grows to a height of 0.5 to 3 m (1 ft 8 in to 9 ft 10 in) and has reddish brown branchlets. The linear phyllodes have an oblanceolate to elliptic shape and are straight or slightly curved with a length of 2 to 8.5 cm (0.79 to 3.35 in) and a width of 5 to 12 mm (0.20 to 0.47 in). It blooms between July and December and produces inflorescences with bright to pale yellow flowers.[3] The inflorescence occur as 6 to 21 racemes along an axis of 1 to 6.5 cm (0.39 to 2.56 in). The spherical flower heads contain six to twelve bright golden flower with dark brown bracteoles. After flowering dark brown to black linear seed pods form with a length of around 9 cm (3.5 in) and a width of 5 to 6 mm (0.20 to 0.24 in). The oblong to elliptic shaped seeds within have a length of 3.5 to 5 mm (0.14 to 0.20 in).[2]

The species was first formally described by the botanist Heinrich Wendland in 1820 as part of the work Commentatio de Acaciis aphyllis. It is also often confused with Acacia rubida[4] The species belongs to the Acacia microbotrya group and is closely related to Acacia kydrensis and similar to Acacia chalkeri and Acacia rubida.[2]

It is found along the Great Dividing Range in western parts of New South Wales, Queensland and Victoria where it is often a part of dry sclerophyll forest or open woodland communities[3] on rocky slopes and creek banks[2] growing in rocky soils.[3] The bulk of the population has a discontinuous distribution from around Walcha in the north down to the upper reaches of the Snowy River north-eastern Victoria.[2]
