Southern gidgee
Acacia pruinocarpa
Southern gidgee is a large spreading tree with height up to 12 m. It has rough, dark brown bark and often has fissures that fold into the wood, giving it a gnarled appearance. Distribution includes the central and northern desert areas of Western Australia, in a 700 km strip eastwards from east of Carnarvon to the north-eastern Goldfields. and is prominent in summer rainfall areas in the Murchison, Goldfields and Gascoyne. It is often associated with mulga on loamy soils.
