Aleuritopteris is a genus of ferns in the Cheilanthoideae subfamily of the Pteridaceae.[1][3] As with some other genera of the Cheilanthoideae, molecular phylogenetic studies have suggested that it is not monophyletic,[1] and so may need to be circumscribed differently in future.
Aleuritopteris is one of a number of genera split off from Cheilanthes in some approaches,[2] including the Pteridophyte Phylogeny Group classification of 2016 (PPG I), in which the genus has about 40 species.[1] As of August 2019, Plants of the World Online includes Aleuritopteris within Hermionitis,[4] a much smaller Cheilanthoideae genus in PPG I.[1] Allosorus was recognized as a separate genus in PPG I, but was included in Aleuritopteris by the Checklist of Ferns and Lycophytes of the World as of January 2020 on the grounds that it was wrongly lectotypified.[2]
As of December 2019, the Checklist of Ferns and Lycophytes of the World recognized the following species and hybrids:[2]
