Acacia aulacophylla is a shrub of the genus Acacia and the subgenus Plurinerves[1] that is endemic to western Australia.

Description

The bushy shrub typically grows to a height of Шаблон:Convert[2] and has glabrous and terete branchlets with hairy golden new shoots. Like most species of Acacia it has phyllodes rather than true leaves. The semi-rigid, glabrous and evergreen phyllodes are ascending to erect and needle-like with a length of Шаблон:Cvt and a diameter of Шаблон:Cvt with eight nerves and furrows in between.[3] It blooms from April to August and produces yellow flowers[2] and produces simple inflorescences simple that appear singly or in pairs in the axils. The spherical flower-heads have a diameter of Шаблон:Cvt containing 40 to 87 densely packed golden coloured flowers. Following flowering leathery and glabrous seed pods form that have a linear shape and are not strongly raised over or constricted between each of the seeds. The pods have a length of Шаблон:Cvt and a width of Шаблон:Cvt with the seeds arranged longitudinally inside. The dull black seeds have a broadly elliptic shape with a length of Шаблон:Cvt and a crested periphery.[3]

Taxonomy

The species was first formally described by the botanists Richard Sumner Cowan and Bruce Maslin in 1995 as part of the work Acacia Miscellany. Five groups of microneurous species of Acacia (Leguminosae: Mimosoideae: section Plurinerves), mostly from Western Australia as published in the journal Nuytsia. It was later reclassified as Racosperma aulacophyllum by Leslie Pedley in 2003 and then transferred back to genus Acacia in 2006.[1]

Distribution

It is native to an area in the Wheatbelt, Mid West and Goldfields-Esperance regions of Western Australia where it is commonly situated on plains, breakaways and laterite or granite hills growing in clay, loamy, sandy or rocky soils.[2] It has a scattered distribution with the bulk of the population found from around Byro Station in the north to around Morawa in the south to around Cue in the east as a part of scrubland communities dominated by other species of Acacia.[3]
