Goodyera foliosa (Lindl.) Benth. ex C.B.Clarke: 2 very high res. images.
Habit : Wild
This is interesting. The leaves in Hong Kong on Goodyera foliosa do not look so bluish!!
I cant confirm what this is without flowers, but then I cant remember what else it can be. Goodyera seikoomontana also has bluish hue on the leaves. But that species is not found in Nepal I think.
I shall check the flowering
What about Goodyera viridiflora (Blume) Blume, … ?
Interesting. It has this grey tinge on the leaves. Does look like Goodyera but cant confirm the species.
