Coeloglossum is a genus of orchids. It has long been considered to have only one species,
Coeloglossum viride, the
frog orchid. Some recent classifications regard
Coeloglossum as part of the larger genus,
Dactylorhiza, so that
C. viride becomes
Dactylorhiza viridis. Other sources continue to keep
Coeloglossum viride separate.
