Dear Smita ji, Ritesh ji,
Thanks for your response. During the same trek i had seen one more tree which had leaves different than what i had posted here. I was thinking that one to be Debregeasia longifolia. I am posting those photographs in a seperate mail to avoid mix up. Kindly check my next email with subject line Debregeasia longifolia-260111PKA.
Thanks
regards
Prashant
