I think this may be any Euonymous sp.

Thank you … for the lead.
Euonymus porphyreus Loes.   ??? 

This is certainly Euonymus.

The flowers are 4-merous as well as 5-merous in the same image. 
This is matching with Euonymus theifolius Wall. ex M.A. Lawson. The flowers are recorded to be 4-merous in literature!
Wonderful capture. The altitude is also almost matching.
Please check.

I am still not sure about the ID and think that it is  more close to Euonymus porphyreus Loes.
keeping in mind length of Peduncle and flower color.  Enclosing links for your kind reference.




However, not much reference is found in the web.

Now see E. theifolius and please see the conspicuously raised lateral nerves similar to your image.  Now decide.

Please check at the link for the original material of E. porphyreus. Here it seems to be a distinct species, showing one collection from Nepal.

Now if you think that this is E. porphyreus then this should be a new record for India!
Please enlarge the images by clicking on them and then decide.

The identification issue is over. This is Euonymus porphyreus Loes. as pointed out by … and this forms a new record for India as pointed out by me. After seeing the original material of this species in the Edinburgh Herbarium, I confirmed the conclusion of …
Next issue is formal reporting of the species from India and this can be done by … If he has collected specimen then he can write a good note (paper) on it and publish in Journal of Japanese Botany or Edinburgh Journal of Botany or to any other suitable Journal. 
If he has not collected any specimen, then he has to go back to the exact locality and collect specimens. 
Looking forward for a good publication on this by

Thank you  for the ID validation … Blunder, no specimen.

Some differences I would like to bring to your notice.
Image posted in the efloras of Euonymus frigidus Wall. does not seem matching with my post..

Thanks a lot, …, for the interesting discussions.
After perusing all details discussed in this thread, I also feel it is more closer to Euonymus frigidus Wall. syn. Euonymus porphyreus Loes.
Images at eflora seems to show it in different condition and time period.

It was a great experience sharing knowledge with experts 

and gaining knowledge. Wish I could have brought the specimen. Thank you … once again.
