Really nice photograph and back up literature
I hope this episode also helps in identifying this perhaps another related plant unidentified at FOI, , which unlike Ranunculus has more than 5 (mostly 6) petals and nearly circular leaves with deeply cordate base and crenate margins.
To me this unidentified plant appears to be Ranunculus sarmentosus Adams, placed in distinct genus Halerpestes (6-10 petals) and names H. sarmentosa, but treated as synonym of Ranunculus cymbalariae Pursh. in Revision of Indian Ranunculus:

Thanks a lot for the compliments.
Are you talking about TW549 on FOI unidentified list?

Respected Sir,
With flowers I dont mind calling that plant as Ranunculus cymbalariae,
but leaves are pretty different. This is reported from Sikkim
according to the reference. But as you say the number of petals. I
imagine if I have any other option. He does state that the species is
highly variable.
Leaf matches well with Ranunculus stewartii.
Regards
Pankaj
