摘　　要：报道了中国兰科(Orchidaceae)隔距兰属(Cleisostoma Blume)一新记录种:角唇隔距兰(C.tricornutum Averyanov)。该种与C.crochetii(Guillaumin)Garay、C.parishii(J.D.Hooker)Garay相近,因其有不分枝的线状花粉团柄、球状的花粉团块和一个先端短喙状的半球形药帽而与C.crochetii(Guillaumin)Garay相区别;因其有松散、罕分枝的花序,长角状的唇瓣侧裂片而与C.parishii(J.D.Hooker)Garay相区别。提供了新记录种的形态描述及图片。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.
