Cheirostylis tortilacinia C. S. Leou (Orchidaceae), a new record for India and its typification

Abstract Cheirostylis tortilacinia C. S. Leou (Orchidaceae), has been reported for the first time in India from Arunachal Pradesh and West Bengal. Cheirostylis tortilacinia is morphologically allied to Cheirostylis parvifolia during anthesis but clear differences can be traced on closer examination of the vegetative morphology and the floral characters. Detailed taxonomical description along with photoplates, species comparison table with the allied species from India, and notes on typification have been provided in this current communication to aid in easy identification of this species.
