Aceratium

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

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

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