Fruit for ID, Andaman NAW-FEB21-06
If possible, kindly identify this fruit from Andaman – the local name is “Rehath” – could it be Cordia subcordata?


Is it eaten ? Where the images were taken in Andamans ?

Looks different.

Can it be Manilkara or Diospyros


Diospyros only.


Ill add more pictures of other details when i can, hopefully next month.


This is found even around Port Blair.


This is Ternstroemia wallichiana

Ternstroemiaceae
Local  Name: Jungli Sapota
Look at the accrescent clayx. Manilkara does not have acrescent calyx like this. Though some species of Diospyros are having accrescent calyx, it is different.
