Acacia awestoniana, commonly known as the Stirling Range wattle,[1] is a shrub of the genus Acacia and the subgenus Plurinerves.
The spreading viscid shrub or tree typically grows to a height of 2.4to and to a width of around 40NaN0. It blooms from September to November and produces yellow flowers. The obliquely widely elliptic to elliptic phyllodes are 1.5to long and 11to wide. The simple inflorescences have globular flower heads with a diameter of 5to containing 54 to 60 golden flowers. The seed pods that form later are straight to narrowly oblong. They have a length of around 2.2NaN and a width of 3to and contain glossy brown oblong-elliptic seeds.[2]
It is native to a small area in the Great Southern region of Western Australia. The plant is found on the lower slopes, on flats and along watercourses and grows in loamy or sandy clay loamy soils.
A. awestoniana is confined to a small area with the Stirling Range National Park and fewer than 1,000 individual plants are known to exist.[3] It is usually found as a part of Eucalyptus woodland communities, associated species include Eucalyptus wandoo, Eucalyptus redacta and Acacia pulchella.[3]
