I do not think so. What else can it be?

Could it be Argostemma??

This is a Rubiaceae member.

Argostemma sp

Yes, Argostemma sp.

As per the checklist of India- 9 species in India.

Thank you … for validating my guess on Argostemma. I checked A. courtallense also earlier but it has got no distribution.

I tried checking these species in POWO and GBIF, but it does not match as per
https://powo.science.kew.org/names:743702-1
https://www.gbif.org/species/2917240
https://www.gbif.org/occurrence/gallery?taxon_key=2917195
https://www.gbif.org/species/2917345

What are the species reported in your book with keys?

I think this could be an undescribed taxon of Argostemma? Please check it carefully as we cannot fix its identity properly to any known entity of the genus.

Or it may be some species reported from Myanmar as it is bordering it.

Argostemma ebracteolatum E.T.Geddes ?? It has got distribution in Myanmar.

Yes, appears quite close to images of Argostemma ebracteolatum E.T.Geddes at
https://www.thaiscience.info/Journals/Article/TFBB/10994922.pdf

OK … It  should be new to India.
