The name alludes to the sweet scent of the flowers. Similar to the South Australian species Acacia iteaphylla which is a more bushy shrub and has the seeds longitudionally placed in the pod. Several subspecies are recognized in Morrison & Rupp (1995). An individual plant with pink inflorescences and somewhat darker bluish green phyllodes has been recorded in the Sydney region, July 2011.
