Cheiroglossa is a genus of fern in the family Ophioglossaceae, subfamily Ophioglossoideae, with two species.

Taxonomy

[edit]

The Smith et al. classification of 2006, based on molecular phylogeny, lumped Cheiroglossa within Ophioglossum, in the Ophioglossaceae.[1] The Christenhusz et al. classification of 2011 maintained it as a separate genus within Ophioglossaceae,[2] as did the Pteridophyte Phylogeny Group classification of 2016 (PPG I),[3] while it was returned to the synonymy of Ophioglossum by the Christenhusz and Chase classification of 2014.[4][5] The PPG I classification additionally assigns it to subfamily Ophioglossoideae, which corresponds to the circumscription of Ophioglossum used in Christenhusz and Chase.[3][4]

Species
