Distribution and Ecology

An introduced species originally from Africa, now naturalised in WA, NT, CYP, NEQ, CEQ and southwards to south eastern Queensland. Altitudinal range from near sea level to 450 m. Grows in disturbed gallery forest and monsoon forest.

Natural History & Notes

This species was probably introduced into Northern Australia by Macassan fishermen before European settlement of Australia. The introduction attains greater significance when it is remembered that the Tamarind probably originated in Africa and was introduced into South East Asia by way of some of the ancient sea trade routes which existed a long time ago.

This species has had a long history of use by people particularly in Africa and Asia. It has been used for a large number of purposes. e.g. animal fodder, food for people and medicinal uses.
