Cheiroglossa is a genus of fern in the family Ophioglossaceae, subfamily Ophioglossoideae, with two species.
Taxonomy
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
As of August 2019, the Checklist of Ferns and Lycophytes of the World accepts two species:[6]
- Cheiroglossa malgassica (C.Chr.) Pic.Serm.
- Cheiroglossa palmata (L.) Presl
