Acacia aciphylla is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is a bushy, prickly shrub with down-turned, rigid, sharply-pointed phyllodes, flowers arranged in a oval heads usually arranged in pairs in leaf axils, and linear pods up to 90 mm (3.5 in) long.

Description

The shrub is prickly with a dense and bushy habit typically growing to a height of 0.6 to 1.8 metres (2 to 6 ft).[2] It has glabrous branchlets and phyllodes. The sessile phyllodes are decurrent on branchlets. They are rigid, erect, straight and terete to slightly rhombic in cross-section. Each phyllode is 6 to 12 centimetres (2.4 to 4.7 in) in length with a diameter of about 1.5 millimetres (0.06 in).[3] It flowers from July to September producing densely packed golden-yellow flowers. The inflorescences are simple with two found 2 per axil. The heads of each inflorescence has an obloid shape and are about 6 to 9 millimetres (0.24 to 0.35 in) in length with a diameter of around 2 mm (0.08 in). Following flowering, seed pods are produced that have a linear shape that is slightly raised between seeds. the pods are straight with a length of about 9 cm (4 in) and a width of 2.5 mm (0.10 in).[2][3][4]

Classification

The species was first formally described by the botanist George Bentham in 1855 in the journal Linnaea: Ein Journal für die Botanik in ihrem ganzen Umfange, oder Beiträge zur Pflanzenkunde.[5][6]


This species in included in the subgenus Phyllodineae, section Juliflorae.[7]
