Epipactis species- Juphal, Dolpa, Nepal

I think this is an Epipactis. Cant confirm the species without open flowers.

Could it be Epipactis royleana Lindl. according to the attached image from a book ?

Not possible to confirm.
Epipactic royleana, E. gigantea, E. helleborine and E. veratrifolia are there in Nepal. Both veratrifolia and royleana can have red to greenish-red buds.
You can wait for few days, will open soon.
