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]
Some species, previously included in Acacia and distributed in the
Indian Ocean, tropical Asia and tropical
America are now classified under:
