Roscoea alpina ?- 24022010 JM6- Bhutan Flora: 3 high res. images.
I am attaching old images one by one for identification, as I didn’t have time to post them earlier.
I think these are from Thimphu or nearby tourist places in Bhutan at an elevation of more than 7,500 ft. 

Roscoea tibetica Batalin

Yes, it is R. tibetica. There are four forma: alba, albo-purpurea, rosea, and roseo-purpurea. The colour of the flowers shows some variation, which may be due to differences in camera settings.
