Kindly see the attached pdf : Rediscovery of Ophiorrhiza radicans (Rubiaceae) from the southern Western Ghats, India’

This species O.radicans Gardn. was mentioned as an Extinct species in ‘1997 IUCN Red List of Threatened Plants’ (Rao et al. 2003). It is really great that an extinct species was rediscovered.

The other thing which we conclude from it is that our field investigations are not sufficient to state any species as extinct in any document.

Hearty congratulations … It is a great feeling.
