This research reports one little known species of Coelogyne (Orchidaceae) from China, C. mishmensis Gogo, and four new record species in Tibet, C. fuscescens Lindl., C. nitida (Wall. ex D. Don) Lindl., C. schultesii Jain et Das and C. viscosa Rchb. F. Among them, C. mishmensis and C. fimbriata Lindl. are very similar, but the flowers of C. mishmensis are large, and the edge of the lip flap is thick and hairy, which is different from the tassel-like lip. The similar species of C. fuscescens are C. assamica Linden & Rchb. f. and C. fuscescens Lindl. var. brunnea Lindl., but the boundary of the three is not clear. By searching for type specimens, from the morphology and color of plants and flowers, the species reported in this article is closer to C. fuscescen, and C. nitida is similar to C. corymbosa. This article would provide features to distinguish the two species. The appearance of C. schultesii that is not in bloom can easily be confused with C. prolifera,but subtle features such as warty protrusions on the sheath and two folds on the lips are easy to distinguish. Descriptions and photographs for diagnostic characters are provided. The discovery of the new records expands the records of Coelogyne Lindl. in Tibet and China, and would provide useful information for the study of Orchidaceae diversity and conservation.
