It has a disjunctive distribution, with the species occurring in Sri Lanka and southern India, and in Assam, Bangladesh and other parts in the north of the Indian subcontinent.

It grow less well in areas of degraded open forest, settled cultivation, homestead gardens and some human settlements.

It natively occurs in the Sinharaja Forest Reserve, Sri Lanka,[4] and is found in various protected areas of Assam, including Nameri National Park, Dibru-Saikhowa National Park, Pakke Tiger Reserve and Hoollongapar Gibbon Sanctuary.

Use of the plant is recorded historically in India, the fruit was believed to ward off evil spirits and omens.
