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 [update], 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 [update] on the grounds that it was wrongly lectotypified. [2]
As of December 2019 [update], the Checklist of Ferns and Lycophytes of the World recognized the following species and hybrids: [2]
