Dear all, I am still not sure but the plant looks very close to S. hamiltonii too. Unfortunately I could not find any authentic literature for S. hamiltonii on net.

May I request Tabish sir to pl check the following link before finalizing the ID http://groups.google.com/group/indiantreepix/browse_thread/thread/3044d8ad8e51e918/39e616cb3342b7d4?hl=en&lnk=gst&q=Sterculia+Raju+Das#39e616cb3342b7d4 Best regards, Ritesh.
