Acacia crenulata

Acacia crenulata is a shrub or tree of the genus Acacia and the subgenus Plurinerves that is endemic to a small area of south western Australia.

Description
The bushy shrub or tree typically grows to a height of 0.7 to 3 m and can have a rounded or obconic habit. It has glabrous branchlets with crenulate-resinous ribbing. Like most species of Acacia it has phyllodes rather than true leaves. The glabrous, leathery and evergreen phyllodes have a narrowly elliptic to linear-elliptic shape with a length of 2 to 6 cm and a width of 2 to 6 mm with yellowish and resinous margins and a prominent central nerve with many indistinct closely parallel secondary nerves. It produces yellow flowers.

Distribution
It is native to an area in the Goldfields-Esperance and the Wheatbelt regions of Western Australia where it is commonly situated on breakaways, among granite outcrops and on rocky rises growing in sandy or clay soils. It is found in the Chiddarcooping Rock and Walyahmoning Rock areas near Bullabulling as a part of low Eucalyptus wandoo woodland communities and is often associated with other species of Acacia, Allocasuarina campestris and Melaleuca uncinata.
