Genus of ferns
Didymoglossum is a tropical genus of ferns in the family Hymenophyllaceae . It comprises more than 30 epilithic or low-epiphytic species under two subgenera.[ 2] The genus is accepted in the Pteridophyte Phylogeny Group classification of 2016 (PPG I), but not by some other sources which sink it into a broadly defined Trichomanes .
Taxonomy
The genus Didymoglossum was first described by Nicaise Auguste Desvaux in 1827.[ 1] Its status, like other genera in the subfamily Trichomanoideae , remains disputed. The Pteridophyte Phylogeny Group classification of 2016 (PPG I) accepts the genus, placing it in the subfamily Hymenophylloideae and saying that there are about 30 species.[ 3] As of October 2019[update] , the Checklist of Ferns and Lycophytes of the World listed 55 species,[ 1] whereas Plants of the World Online sank the genus into Trichomanes .[ 4]
