Vernacular names

Acacia aemula is a shrub belonging to the genus Acacia and subgenus Alatae. It is native to an area along the south coast of Western Australia.[1][2]


The shrub is prostrate to semi-prostrate, open branched and rush-like that typically grows to a height of 0.2 to 0.4 metres (0.66 to 1.3 ft). It produces white-cream flowers from May to June[1]

The species was first formally described by the botanist Bruce Maslin in 1995 in the work Acacia Miscellany 13. Taxonomy of some Western Australian phyllocladinous and aphyllodinous taxa (Leguminosae: Mimosoideae) as published in the journal Nuytsia. It was later reclassified as Racosperma aemulum by Leslie Pedley in 2003 then returned to the genus Acacia in 2006.[2]

Two subspecies are recognized :

Acacia aemula subsp. aemula[3]
Acacia aemula subsp. muricata[4]


It is found along the south coast of Western Australia in the Great Southern and Goldfields-Esperance regions extending from around Albany east to Cape Arid National Park where it grows among granite outcrops and flats near creeks in sandy soils.[1]
