Acacia microsperma, commonly known as bowyakka, is a shrub of the genus Acacia and the subgenus Plurinerves that is endemic to an area of eastern Australia.[1] It is rated as least concern according to the Nature Conservation Act 1992.[2]
The tree can grow to a height of about 10 m (33 ft) and has sub-glabrous to moderately hair branchlets that appear quite scaly and leprous. Like most species of Acacia it has phyllodes rather than true leaves. The green to grey-green, slightly hairy and evergreen phyllodes have a linear shape and are quite straight with a length of 7 to 14 cm (2.8 to 5.5 in) and a width of 1.5 to 4 mm (0.059 to 0.157 in) and have multiple obscure, closely parallel nerves.[1] When it blooms it produces inflorescences that appear in groups of one to four with spherical flower-heads that have a diameter of 4 to 5 mm (0.16 to 0.20 in) and contain 20 to 40 golden coloured flowers. Following flowering firmly chartaceous seed pods form that resemble a string of beads. The pods are straight with a length of up to 6 cm (2.4 in) and a width of 2 to 3 mm (0.079 to 0.118 in) and are sparsely haired. The brown seeds inside have a narrowly elliptic shape with a length of 2.5 to 4 mm (0.098 to 0.157 in) and have a fleshy aril that is repeatedly folded.[1]
Taxonomy
The species was first formally described by the botanist Leslie Pedley in 1974 as a part of the work Contributions from the Queensland Herbarium. Pedley reclassified it as Racosperma microspermum in 1987 but it was transferred back to genus Acacia in 2001.[3]
