It may be Launaea procumbens (Roxb.) Ramayya & Rajagopal as per images and details herein.  

Looks different from images of Launaea intybacea (Jacq.) Beauv. at POWO.

I tried but failed to find the difference between the two on the net.

Check FoC illustrations of L. procumbens - http://www.efloras.org/object_page.aspx?object_id=121243&flora_id=2 and http://www.efloras.org/object_page.aspx?object_id=121242&flora_id=2

and

descriptions in FBI. FI, FoC etc.

The leaves of L. procumbens will have dense white cartilaginous margins.

The leaves of L. intybacea also feature cartilaginous teeth, but with fewer white cartilage , I think. (refer KEW)

Leaves are membranous, cauline leaves 1/2 amplexicaul auricled in L. intybacea, though not seen here. Heads 1/2 inch long. 

It might be some other as well.

Launaea intybacea (Jacq.) Beauverd features pale yellow flower, and to my understanding, phyllaries are exactly like https://groups.google.com/g/indiantreepix/c/TtioPVzgur0/m/xzDUZI7qMtgJ.

I think it might be same sp., though good phyllary pictures are NA.

[surajit koley]

Forgot to tell that first distribution has to be checked.

As per FBI, Lactuca heyneana DC. is distributed in NW India, Western peninsula etc.

As per another source it is in UP, Bangalore etc.

Capitulum in L intybacea features 12-35 florets, L. procumbens 15-20(30) florets (FoC).

Launaea aspleniifolia (Willd.) Hook.fil. ?

Thank you
