Request to identify this tree, found it in wild in Hampi area in Karnataka……. picture taken few days back. (18.10.13)

It could be Gyrocarpus americanus, The helicopter tree. Do not know the reason for the silvery trunk which is usually on one side only, maybe to prevent heat absorption

Yes, rightly IDd by … I made a quick visit to Hampi on the leads given by … and found many trees in full bloom.

On searching I found that this unusual plant belongs to the family Hernandiaceae.

Can this be Gyrocarpus americanus? (Helicopter tree)

Give more details about the inflorescence…A species of Sapium of Euphorbiaceae?..

This tree is Gyrocarpus americanus Jacq. (Hernandiaceae)

A young tree, planted by the same nature lover in Nasik.
Seed was brought from Andaman.
Hoping our Andaman expert, …, can identify it.

It is the sapling of Gyrocarpus americanus (Hernandiaceae)

Great! Many thanks for the id. Is it found in India?

Although it matches images on Google search. Somehow, the leaves in FOI look different. Here is the link.

Leaves quite variable in the saplings and matured tree. It is a tree of dry deciduous forest and foothills.
