Acacia brachyphylla is a shrub of the genus Acacia and the subgenus Plurinerves that is endemic to a small area in south western Australia.
Description
The spreading upright shrub typically grows to a height of 0.2 to 0.3 metres (0.7 to 1.0 ft). It has densely hairy and terete branchlets that have persistent Stipules narrowly triangular stipules that are about 1.5 mm (0.059 in) in length. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen, ascending to erect phyllodes are straight to curved with a length of 3 to 12 mm (0.12 to 0.47 in) and a width of around 1 mm (0.039 in) with six to eight minutely villous nerves. It blooms from August to October and produces yellow flowers. The simple inflorescences occur singly or in pairs and have spherical flower-heads with a diameter of 3 to 4 mm (0.12 to 0.16 in) containing 8 to 12 golden coloured flowers. Following flowering thinly coriaceous to firmly chartaceous seed pods have a linear shape. The pods have a length of up to 5 cm (2.0 in) and a width of 1.5 to 4.5 mm (0.059 to 0.177 in) and can be hairy or glaborus or covered in a fine white powder. The mottled brown to grey-brown seeds have a broadly ovate shape and a length of 2 to 2.5 mm (0.079 to 0.098 in).
