Acacia obesa is a shrub of the genus Acacia and the subgenus Plurinerves that is native to a small area of south western Australia.

Description

The low spreading shrub typically grows to a height of 0.3 to 0.6 metres (1 to 2 ft)[1] It has cylindrical and tapering branchlets that can be quite hairy. Like most species of Acacia it has phyllodes rather than true leaves. The cylindrical evergreen phyllodes are slightly to strongly incurved but can occasionally be quite straight. The thick and glabrous phyllodes have a length of 1 to 2.5 cm (0.39 to 0.98 in) and a diameter of 1.2 to 1.75 mm (0.047 to 0.069 in) and have 12 to 16 longitudinal fine raised nerves.[2] It blooms from July to September and produces yellow flowers.[1]
Taxonomy

The species was first formally described by the botanists Richard Sumner Cowan and Bruce Maslin in 1995 as a part of the work Acacia Miscellany 15. Five groups of microneurous species of Acacia (Leguminosae: Mimosoideae: section Plurinerves), mostly from Western Australia as published in the journal Nuytsia. It was reclassified by Leslie Pedley in 2003 as Racosperma obesum then transferred back to genus Acacia in 2014.[3]
Distribution

It is native to an area in the southern Wheatbelt region of Western Australia where it is found growing in sandy or gravelly loam soils.[1] The shrub has a limited distribution and is confined to an area between Lake Grace, Lake King and Hyden where it is usually a part of open scrub, open heathland or low open woodland communities.[2]
