Dear all, is this identification right? please correct me if I am wrong.

This is Begonia dipetala var dipetala and not B. malabarica. Begonia malabarica is an endemic species in Kerala. All the names published under the name B. malabarica from other part of India need a careful study.
In fact, B. malabarica was based on Rheede’s Tsjeria-narinampuli. It was validated by Lamark. It is an endemic species of kerala.
For further Reading kindly see{ 1}Santhosh Kumar E.S., Seema G. Gopal and G.M. Nair 2005. Re-appearance of Rheede’s Tsjeria-narinampuli – Its identity after the discovery and a note its allied species. Begonian 72 (Jul/Aug): 135-140.

Thank you …, what are the peculiar character that diffrentiate B.dipetala from B.malabarica? As you said, it is being reported from TN too.
