Abstract

Gastrodia indica sp. nov. has been described as a new species from Sikkim, India. This is the first cleistogamous species of the genus Gastrodia discovered from India. It is morphologically allied to G. exilis & G.dyeriana but critical examination revealed considerable differences in floral morphological characters. A detailed taxonomical description along with photoplates, comparison with the allied species and keys for all Gastrodia species from India have been provided to aid in easy identification.
