Abstract
A new species, Panisea moi (Orchidaceae: Epidedroideae: Coelogyninae) from Mount Wuzhi and Mount Jianfengling of Hainan Island is described and illustrated. The most significant differences from the closest species, P. vinhii, are that P. moi has subentire labellum, two longitudinal labellum keels that extend from middle of the hypochile to 2/3 of the length of the epichile and thickened at the ends; the rachis is also straight.
