Botrychiaceae

Botrychiaceae (moonwort family) was recognized as a segregate family of ferns. The family included the genera Botrychium (the moonworts), Botrypus (the rattlesnake fern), and Sceptridium (the grape-ferns). Older fern classifications took a broad circumscription of Botrychium and included the genus in family Ophioglossaceae.

Botrychium lunaria

The family is not recognized in the classification of Smith et al.,^[1] who instead subsume the Botrychiaceae into the Ophioglossaceae.
