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, which was continued in the Christenhusz et al. classification of 2011 and the Christenhusz and Chase classification of 2014. It is recognized as a distinct genus in Ophioglossaceae by the Pteridophyte Phylogeny Group classification of 2016 (PPG I). The PPG I classification additionally assigns it to subfamily Ophioglossoideae, which corresponds to the circumscription of Ophioglossum used in Christenhusz and Chase.

Unassigned species:

  • Ophioderma intermedium <small>(Hook.) Nishida</small>
  • Ophioderma simplex <small>(Ridl. ex Bower) Nishida</small>
  • Ophioderma subsessile <small>Amoroso & Coritico</small>
