Abstract:Cleisostoma tricornutum Averyanov is reported from China for the first time. This species may be related to C. crochetii (Guillaumin) Garay, from which it differs in having a simple filiform pollinarium stipe, subglobular pollinia and a hemispheric operculum with a short obtuse beak. This species also is similar with C. parishii (J. D. Hooker) Garay, but differs in having lax, rarely branched inflorescence and long, horn-shaped, lip side lobes. Description and photos of the new record are also provided.
