Sharing some pictures I guess is Strobilanthes atropurpureus Nees. shot at Chandragiri Hill Kathmandu Nepal on 19 September 2016 at 8200 ft.
Nepali Names: अङ्गारे Angaare/ जरो बुटी Jaro Buti / किब्बु Kibbu  / कगदिल Kagadil
This is Strobilanthes lachenensis C.B. Clarke.
It is scattered in the Himalayas from central Nepal to SW China.

Thank you for correcting ID.
I did not find pic on web however one pic from a book published in Nepal. Is it the correct ID on book ?

Yes, I think this is correctly Strobilanthes lachenenensis. The picture is not so helpful as those sent by ... which show the habit of the plant and the complete inflorescence. These are usually very important in identifying the different species.
Is it not Strobilanthes attenuata ?
I think this is Strobilanthes lachenensis C.B. Clarke.
Note compound inflorescence, leaves cuneate, not cordate at base - it is possible there could be hybrids between lachensisis and attenuata - they certainly hybridize easily when cultivated together.

Strobilanthes ... ???

Did you check at 

Strobilanthes lachenensis C.B. Clarke  ???

I think it is Strobilanthes lachenensis but I would like some time to consider other possibilities.

Strobilanthes atropurpureus : 3 posts by 3 authors. Attachments (8)
Sharing some pictures of Strobilanthes atropurpureus shot at Nagarkot Nepal on 13 August 2016 at 6800 ft.

I am not sure what this is but it is not Strobilanthes atropurpurea, which has a glabrous corolla. It might be S. lachenensis (which is very variable) but I am doubtful. The altitude suggests that is a good possibility.
Have you got a photo showing the whole plant I particular the complete inflorescence showing how it is branched.

Adding some more images from same location same date as you have advised 
for further scrutiny!

I think this is a form of Strobilanthes lachenensis. It is not Strobilanthes atropurpurea which has a glabrous corolla and subequal calyx lobes. The plant in the photographs has a hairy corolla and one calyx lobe is clearly longer than the others.
Strobilanthes lachenensis is very variable in size and inflorescence development and I have puzzled over some specimens in the past (see my comments in Edinburgh Journal of Botany 51 (2): 246 in 1994) but without seeing a specimen this is my best guess at the identity of these photographs.
I know S. lachenensis and S. attenuata hybridise when cultivated together and some of the variation might be explained by hybridization with another Strobilanthes species growing in the same area.
