Acacia leptopetala is a shrub belonging to the genus Acacia and the subgenus Phyllodineae that is endemic to an area of south western Australia .

Description

The dense and multistemmed shrub typically grows to a height of 1.0 to 3.0 metres (3.3 to 9.8 ft).[1] The glabrous branchlets are often covered in a fine white powdery coating. Like most species of Acacia it has phyllodes rather than true leaves. The thinly coriaceous, glaucous and evergreen phyllodes have a narrowly elliptic to narrowly oblanceolate shape that can be recurved. The phyllodes normally have a length of 2 to 5.5 cm (0.79 to 2.17 in) and a width of 3 to 11 mm (0.12 to 0.43 in) and have a raised midrib.[2] It produces yellow flowers from November to January.[1]

Taxonomy

The species was first formally described by the botanist George Bentham in 1855 as part of the work Plantae Muellerianae: Mimoseae as published in the journal Linnaea: ein Journal für die Botanik in ihrem ganzen Umfange, oder Beiträge zur Pflanzenkunde. It was reclassified as Racosperma leptopetalum in 2003 by Leslie Pedley then transferred back to genus Acacia in 2006.[3]

Distribution

It is native to an area in the Great Southern, Wheatbelt and Goldfields-Esperance regions of Western Australia where it is commonly found on flats growing in a variety of soils.[1] The species is located from around Bencubbin in the north to around Nyabing in the south west and as far as Ravensthorpe in the east where it is found growing in loamy, clay, sandy loam, sand and sandy gravel soils as a part of mallee scrub.[2]
