Taxonomy

The genus Abrodictyum was erected by Carl Presl in 1843.[1] Its status, like other genera in the family Hymenophyllaceae, remains disputed. The Pteridophyte Phylogeny Group classification of 2016 (PPG I) accepts the genus, placing it in the subfamily Trichomanoideae, and saying that there are about 25 species.[2] As of October 2019, the Checklist of Ferns and Lycophytes of the World listed 41 species,[1] whereas Plants of the World Online sank the genus into Trichomanes.[3]
