Acacia mimica

Acacia mimica is a shrub of the genus Acacia and the subgenus Plurinerves that is endemic to south western Australia.

Description

The dense shrub typically grows to a height of and can have an erect or semi-prostrate habit with glabrous to hairy branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The patent to erect, rigid to leathery, grey-green and glabrous phyllodes have a narrowly elliptic or linear to oblanceolate-linear shape that is curved with a length of and a width of with many raised and irregular closely parallel nerves and prominent yellow marginal nerves. It blooms from July to October and produces yellow flowers.

Taxonomy

There are two recognised varieties:

Acacia mimica var. angusta
Acacia mimica var. mimica

The yellow nerves on the plant make it similar in appearance to Acacia patagiata.

Distribution

It is native to an area in the Wheatbelt, Great Southern and Goldfields-Esperance regions of Western Australia where it is commonly situated on undulating sandplains, rocky ridges and hills and rises growing in clay, loam or sandy soils that can contain gravel. The range of the plant extends from around Goomalling in the north west down to around Borden in the south east and then out as far as Raavensthorpe in the east with outlying population found near Scaddan and Mount Burdett even further to the east.
