Balinghasay is a wide spread species growing in China, Taiwan, Myanmar, Andaman Islands, Indochina, Thailand, throughout Malesia (including Singapore) to New Britain (Papua New Guinea), Solomon’s Islands, and Australia.  It also grows in some parts of the Indian sub-continent and the Andaman Islands of India. It is a characteristic tree of the Australian rain forests growing along water courses in Northern Australia.

            Balinghasay trees bear heavy crops of small fruits which are edible but not of very good quality.  Though the fruits are not marketed, but these are used by local people and aboriginals in Australia.
