Dear Bidhan Chandra Das,

It is very difficult to identify a plant without reproductive structures. Moreover, picture quality is also poor. Please use the attached source in identification of this plant species.

Good luck!

yes,

ID of plants by photos (not very professional) is not possible7

Sorry.

Dear Dr. Singh,

Thanks for your comments and sending the book. Yes, the picture quality is poor, but unfortunately, I have no better quality photo- although I have a poor herbarium (without flower/seed).

The book (you sent) does not include this plant.

Thanks for your cooperation.
