This liana was shot a few years ago, was found growing in cultivation in Kurukshetra University Kurukshetra, Haryana..
I have tried to identify it, and I am quite convinced that it may be Banisteriposis laevifolia A. Juss....
This is for validation please, and if correct, an eFI entry can be created, along with rectifying some images under Stigmaphyllon emarginatum
I hope to get validation/correction..
