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.
