Dear Rajuji, Thanks for posting this photo.
As said by Mahadeswara Ji, I too think this as a different species of Sauropus. Pl follow the below given link to see the images of S. androgynous posted by me a few days before. The leaves look very different here. I request you to pl check with Fl. Assam which I am unable to access here in Korea. http://groups.google.com/group/indiantreepix/browse_thread/thread/4a60e295dc2cb69a/58a0e08a95ae1a4f?lnk=gst&q=Sauropus+androgynous#58a0e08a95ae1a4f Regards, Ritesh.
