Pl. check comparative images in efi at Begonia
Does not seem to match with any comparative images at Begonia
Pl. check Begonia wattii as based on pdf available from link under thread Begonia in Northeast India 
As you have recently published Monograph of North East Indian species, may I request you to pl. assist in the id of this Begonia.

I believe this plant is Begonia annulata K.Koch, the leaves don’t always have the “ring “ marking present.
B. palmata
Thanks, ... But ... confirmed it to be Begonia annulata
... is probably correct on this. I am now seeing this as palmata after looking at it again this morning.

This has 2 stigmas, so is in sect. Platycentrum, probably one of the subspecies of B. palmata.
