Zeuxine yonzoneana sp. nov. (Orchidaceae: Spiranthoideae: Cranichideae: Goodyerinae): a new species from India

Zeuxine yonzoneana, a new species of orchid from India, is described and illustrated. The new species is allied to Zeuxine clandestina Blume. But differs in having leaves during anthesis, ovate-oblong to awl-shaped lateral sepals; lip deeply and broadly bilobed, and serrated epichile margins of the later. The new species also shows variation in flowering period, i.e. September–October for the new species, whereas February–April for Zeuxine clandestina. Colour photographs and line drawing are provided for the taxonomical recognition of the new species.
