Cymboglossum, synonym Ascidieria, is a genus of flowering plants from the orchid family, Orchidaceae.

[1][3] In 1981, Friedrich Gustav Brieger raised it to the rank of genus, but did not correctly cite the basionym, so his name was not acceptable.

In 1983, Stephan Rauschert corrected Brieger's mistake, thus validating the genus name.

A 2018 molecular phylogenetic study of the tribe Podochileae showed that Ascidieria and Cymboglossum should be merged.

However, the authors of this study were not aware of Rauschert's validation of the name Cymboglossum, and incorrectly merged the two genera under the name Ascidieria.
