May be Neurocalyx calycinus (R. Br. ex Bennett) Robins. of Rubiaceae

The specimen is Neurocalyx calycinus (R. Br. ex Bennett) Robins. – Rubiaceae usually found in forest floors of evergreen forests. As our observations go, it is found in undisturbed areas inside evergreen forests, close to or on the rock crevices near streams and streamlets.

Thank you very much …
Thank you very much too … The habitat you described perfectly matches the place I found it in– Meenmutti falls in Aralam WLS. They were growing on rocks and also on the soil.
