Pl. check comparative images in efi at Begonia
Does not seem to match with any comparative images at Begonia
Thanks, … Nearest name with distribution in Arunachal Pradesh I found is Begonia aborensis Dunn.
But images of this species at the following do not match with the images of …
Not at all. B.aborensis. The images what you have send is Begonia burkilli (? ), may be a hybrid. Pl find enclosed the image of aborenensis in the following mail. The mail flowers in B. aborenensis has only 4 petal, while in female FL. It ranges from 2_4. The photo from anjaw is a male flower.
Incidentally, the plant seen at https://groups.google.com/forum/?oldui=1#!topic/indiantreepix/LjSWqRaOOII is B. annulata
