Restricted to dryish sites in foothills and mountain ranges in far eastern Victoria. A small population established recently near McMahons Creek in the Upper Yarra area was presumably derived from seed carried by fire-fighting equipment and a 1925 collection labelled Box Hill is presumably in error or was introduced to the area.

Distinguished from Acacia longifolia by the resinous margins of its thicker, less pliable phyllodes. It fruits very rarely and appears to propagate principally by suckering.
