The genus Ophioderma are distinctive ferns in the family Ophioglossaceae.

Taxonomy

The Smith et al. classification of 2006, based on molecular phylogeny, lumped Ophioderma within Ophioglossum , in the Ophioglossaceae, ^[1] which was continued in the Christenhusz et al. classification of 2011 ^[2] and the Christenhusz and Chase classification of 2014. ^[3] It is recognized as a distinct genus in Ophioglossaceae by the Pteridophyte Phylogeny Group classification of 2016 (PPG I). ^[4] The PPG I classification additionally assigns it to subfamily Ophioglossoideae, which corresponds to the circumscription of Ophioglossum used in Christenhusz and Chase. ^{[4] [3]}

The type species is Ophioderma pendulum .
