Aceratium is a genus of about 20 species of trees and shrubs of eastern Malesia and Australasia, constituting part of the plant family Elaeocarpaceae.[1][2][3][4][5] In Australia they are commonly known as carabeens.[4][5] They grow naturally in rainforests, as large shrubs to understorey trees and large trees.[1][2][4][5]

They grow naturally in New Guinea, the centre of diversity, in New Britain, New Ireland, Vanuatu, Sulawesi, Moluccas,[1] and in Australia, where botanists have formally described five species, only found (endemic) in the Wet Tropics rainforests of north eastern Queensland.[2][4][5]

Some species have uses for their fruits as food and,[1] although not yet well known, some have popularity in cultivation, for example in Brisbane.[citation needed]
