Hymenophyllaceae Martius. Filmy Fern Family.

Key to Hymenophyllaceae

A family of 9 genera and about 430 species. This treatment follows the generic interpretation of Ebihara et al. (2006) and PPG I (2016), which split Trichomanes (as both polyphyletic and morphologically diverse) and retain a broad and monophyletic Hymenophyllum. See Moran (1998) for an interesting discussion and overview of independent fern gametophytes in e. North America.
