Parnassia cordata (Drude) Z.P.Jien ex T.C.Ku ??

Yes, appears close to images at Parnassia nubicola subsp. occidentalis. CoL does not mention its distribution in Nepal and POWO does not mention this subspecies.

Flora of Pakistan says that Parnassia nubicola Wall. has not been reported from W. Pakistan. This is an Eastern Himalayan species characterized by the sepals having 5-7 nerves, and deeply brown or red dotted fimbriate margined petals.

However, Checklist of Nepal and POWO give the distribution of Parnassia nubicola Wall.(syn: Parnassia cordata (Drude) Z.P.Jien ex T.C.Ku) in Nepal.
So we take it as Parnassia nubicola Wall.(syn: Parnassia cordata (Drude) Z.P.Jien ex T.C.Ku).
