Probably B. affine.

Thanks for sharing!

Regards,

Ritesh.

Sir, Chopta is too low altitude(27-2800m) for B.affine which occur above 3500m in Uttarakhand. It may be Bistorta macrophylla.

It looks different from both Bistorta affinis (D. Don) Greene as well as  Bistorta macrophylla (D.Don) Soják

Can it be Bistorta milletii as per Flowers of India and GBIF specimen- one, although I find distribution in Nepal and east of it only?
