I have two snaps of a Begonia sp from Kerala (not sure it is from wild) send by one of my friends. Can someone help me to identify it? 
Male flowers with 4 tepals and female with 5 teapls. Ovary 3-locular with bifid placenta in each locule.
The Begonia was finally identified as Begonia hirtella Link.
