There are about 1080 species of Acacia accepted by Plants of the World Online as at November 2023, with species native to Australia, New Guinea, Southeast Asia, Hawaii and the Mascarene Islands, and introduced to other countries.[1]
An older concept of Acacia included about 1350 species from Australia, Africa, tropical America and Asia, but following decisions made at the 2011 International Botanical Congresses, the name Acacia was reserved for species found in Australia, New Guinea and Southeast Asia.[2][3]
