Yes Garg ji

It was a very interesting long thread in which it was almost decided as Myriactis wallichii till I noticed large foliaceous bracts characteristic of Brachyactis.

I do not think it matches with herbarium specimens at GBIF

[Tabish]

After lot of exploration I too finally think that it should a Bractyactis species. Some involucral bracts becoming large like leaves is an unmistakable character. Neobrachyactis anomala is the closest identification, in my opinion. The distribution and altitude also agrees with it. Please see the following links:
