Very nice pictures of a Rubiaceae plant.
I am not sure about the ID though.
The pictures are showing an important character of Family Rubiaceae.............
Opposite leaves. I have read that often the plants have interpetiolar stipules which are sometimes big and appear like leaves making the leaf pattern whorled..........
Is it the classic case here?
Would like to learn from experts.

Ritesh, it may be Rubia himalayensis. (it is not R. cordifolia).

Yes not Rubia cordifolia in which leaves are with very long petioles, and leaf base usually cordate.

Leaves 2-4 in a whorl and short petioles suggest R. himalayensis as suggested by Vijayasankar ji

Thanks a lot Satish Ji, Gurcharan sir and Vijay anna for your comments
and ID confirmation!

Infact, I was also doubtful about this to be as R. cordifolia. The
typical R. cordifolia I've posted in another thread.

Thanks again!

Regards,
Ritesh.
