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]
