Acacia meiantha

The shrub has an erect or sometimes straggling habit and can grow to a height of around 1.5 to 2.5 m (4 ft 11 in to 8 ft 2 in) and often spreads by suckering. It has smooth greenish brown to grey or light brown coloured bark and angled hairy branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The crowded, glabrous and evergreen phyllodes are straight to slightly curved, with a length of 1 to 6.5 cm (0.39 to 2.56 in) and a width of 0.4 to 1 mm (0.016 to 0.039 in) and have an indistinct midvein. It blooms between July and October producing yellow flowers. The simple inflorescences are found in groups of 2 to 19 in an axillary raceme. The spherical flower-heads have a diameter of 3 to 5 mm (0.12 to 0.20 in) and contain four to eight yellow to dark yellow coloured flowers. Following flowering firmly papery to thinly leathery glabrous seed pods form. The straight or slightly curved pods are more or less flat and straight sided or constricted a little between each of the seeds. the pods are around 2.7 to 8.5 cm (1.1 to 3.3 in) in length and 4 to 7 mm (0.16 to 0.28 in) wide.^[2]

The species was first formally described by the botanists Mary Tindale and C.Herscovich in 1992 as part of the work Acacia meiantha (Fabaceae, Mimosoideae), a new species from the Central Tablelands of New South Wales as published in the journal Australian Systematic Botany. It was reclassified as Racosperma meianthum by Leslie Pedley in 2003 then transferred back to genus Acacia in 2006.^[3] The latin specific epithet of meiantha is derived from the few flowers contained in the flower-heads. The phyllodes resemble those of Acacia linifolia and Acacia boormanii.^[2]
