It does look like a Polygala species.

Please check Polygala sp

To me the plant seems to be some species of Cuanotis.

I think you mean to say Cyanotis. I think it is a Polygala species only.

Ok, I will check. At present, it has been only comparative to Polygala Sp. Chathamattom.

it is a polygalaceae member, may be a new species

I think it may be Polygala chinensis as per images at iNaturalist.
Another species which appears quite close is Vishnu M., Nampy S. 2022. Polygala idukkiana (Polygalaceae), a new species from the southern Western Ghats, IndiaAnales del Jardín Botánico de Madrid 79, as per details herein and as at 12 Identify weed plant and Requesting a herb id_1_081022

it differs with P.chinensis by its hairyness on all parts; the bract is almost cuspidate here, and staminal tube also. let them recheck

To which species out of the mentioned in the publication, you think it is the closest?
