Abstract: Four confused taxa of Cymbidium (Orchidaceae) are discussed taxonomically based on an examination of many living plants. As a result, Cymbidium tortisepalum　Fukuyama and C. omeiense　Y. S. Wu et S. C. Chen are recognized as separate species, C. longibracteatum Y. S. Wu et S. C. Chen as a variety of C. tortisepalum Fukuyama, and C. szechuanicum Y. S. Wu et S. C. Chen as a variety of C. cyperifolium Wall. ex Lindl. Due to the lose of the types and all the cited specimens of Cymbidium longibracteatum, C. omeiense and C. szechuanicum in PE over 30 years ago, their neotypes are here designated.

Key words: Cymbidium, C.　tortisepalum, C. omeiense, C. tortisepalum var. longibracteatum.
