Globba kanchigandhii A. Joe & M. Sabu sp. nov.
Similar to Globba multiflora Wall. ex Baker, but differs from it in having lesser number of flowers in an inflorescence, glabrous peduncle, erect and horn-like free triangular lateral staminodes, short corolla tube, stigma cylindric and presence of persistent bracts even at flowering stage.
Distribution and Habitat: Globba kanchigandhii is so far
only known from the type locality, ie. Phek, Nagaland
and grows as undergrowth in the evergreen and semi-evergreen forests.
Etymology: This new species has been named in
honour of Dr. Kanchi Gandhi, Harvard University for his
valuable contributions to the field of plant nomenclature.
Notes: This new species is closely allied to G.
multiflora in its plant stature, bulbils and labellum
colouration. But markedly differ from it in having fewer
number flowers in inflorescence, erect and horn-like
lateral staminodes, presence of persistent bracts and in
its flowering period. The erect lateral staminodes make
the species distinct from all known species of Globba.
