Taxonomy

Lemmaphyllum was first described by Carl Presl in 1851.^[1] A molecular phylogenetic study in 2019 suggested that Lemmaphyllum was one of a group of closely related genera in the subfamily Microsoroideae; a group the authors termed "Lepisorus sensu lato".^[3]

Species

As of February 2020^[update], the Checklist of Ferns and Lycophytes of the World recognized the following species:^[1]
