Gurcharan ji,
I think this is a wonderful identification - certainly a difficult
one. Sharply toothed leaves with white undersides is convincing. In
one of your pictures, the underside of leaves is white and the nerves
appear reddish, in agreement with the species name rufinervis, meaning
red-nerved.
