Herb for ID from Dalhousie: We had been on educational tour to Dalhousie and Khajiar recently (Nov. 06-10, 2011). This small herb was photographed from near bus stand Dalhousie, the pics are not much informative, yet I hope to get some concrete clues. The flowers are very small, nearly 1cm across, leaves dimorphic.

May be a Begonia sp.

This is not Begonia sp.

Appears close to Valeriana of Caprifoliaceae

I tried all species as per Flora of Pakistan and Checklist of Nepal, but could not find a match.
