The genus ''Cymbidium'' was first formally described in 1799 by

In 1848 Blume moved ''Cymbidium elegans'' to form the genera ''Cyperorchis'' on the basis of the sessile lip that was fused at the base and moved ''Cymbidium iridioides'' (as ''C. giganteum'') to section ''Iridorchis'' in 1854.

created more sections and merged. The genus was revised again in 1970 by P.F. Hunt who changed ''Cyperorchis'' to a section. In 1984 Seth and Cribb divided the genus into three subgenera ''Cyperorchis'', ''Jensoa'', and ''Cymbidium'' with multiple section. Dupuy and Cribb modified the sections in 1988 The three subgeneras were confirmed by molecular phylogeny, however the sections did not show monophyly.

. Today they are among the most popular orchid genera in cultivation. They have decorative flowers spikes and are one of the least demanding indoor orchids. To flower well they need a distinct difference between day and night temperatures in late summer. Plants need to remain outside in autumn until night temperatures drop to near . Cymbidiums have few pests or diseases but can be affected by aphids, spider mites and virus diseases.
