It does not have distribution in India as per POWO.

It is a female tree of Diospyros ebenum (Possibly). I visited Talcher, Angul area of Orissa several times for a mining area survey. There I saw the tree in several locations. There are more numbers in Sacred groves. The tree will be dark brown to black. Wood is black and hard. Close relative of Tendu.
