Strobilanthes atropurpureus Nees ??? : 5 posts by 2 authors. Attachments (10)
Sharing some pictures I guess is Strobilanthes atropurpureus Nees. shot at Chandragiri Hill Kathmandu Nepal on 19 September 2016 at 8200 ft.

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.

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.
Strobilanthes attenuata (Nees) Nees ?? : 4 posts by 2 authors. Attachments (3)
Sharing some pictures I guess is Strobilanthes attenuata (Nees) Nees shot at Hattiban Nepal 5 October 2014 at 4500 ft.
I think more details are required for confirmation or otherwise.
ID still pending !
Looks different from images at 

Pl. try comparative images at genus page,  if you can find a match with these images:

Note the hairy corolla. I think this is Strobilanthes lachenensis, which is quite variable, but it is an odd example, if I am correct in my identification.

I have a couple more I need ID help with this one below. 
Strobilanthes lamiifolia (Nees) T. Anderson
I do not think matches with images at Strobilanthes lamiifolia 

I guess Strobilanthes lachenensis C.B.Clarke !
Definitely not Strobilanthes lamiifolia. Might be Strobilanthes lachenensis but not sure. Any photo of flowers? of the plant? Any altitude or location detail?

I am attaching a photo of the plant with flowers.
1 image.
I think this is Strobilanthes lachenensis but I have a slight hesitation as it is a rather depauperate plant lacking the typical branched inflorescence.

ID for this Strobilanthes please !

Looks like Strobilanthes atropurpurea to me.
I don't think this is S. atropurpurea - the corolla is hairy and sepals are not right.

I Think SK2817 is Strobilanthes lachenensis.
