See text Terpsichore is a genus of ferns in the family Polypodiaceae, subfamily Grammitidoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I).
Rhizomes are radially symmetric or slightly flattened, with orange to brown scales which often bear setulae (small bristles) on the edges and sometimes the surface.
Setae on the leaf tissue are borne singly, rather than in clusters, and hydathodes (enlarged vein endings) do not secrete a chalk precipitate.
[2] Terpsichore was first described by Alan R. Smith in 1993, one of several genera to be recognized to remove many Neotropical grammitids from the genus Grammitis.
The name, originally applied to some members of the group by L. Earl Bishop, but not published by him, honors Terpsichore, the muse of dance.
