I could not find any published article pertaining to this taxon, from India..
this looks like Erigeron bonariensis, or something close to it.
It is quite distinct from Erigeron bonariensis, in every aspect..it is aromatic, with winged stem, wider lance-like leaves, larger heads etc.
How about Laggera alata, although the heads do looks different?
Looks different as per images at
