Abstract

An interesting new species of jewel orchid, Zeuxine drukyulensis is described and illustrated from warm broadleaved forests in western Bhutan. It is closely allied to Zeuxine nervosa and Zeuxine rolfeana, however, differs in various morphological characters, primarily the structure, size and colour of the flower. The new species is assessed as Data Deficient (DD) as per the IUCN Red List guidelines.
