 In 2018, Dong and Zuo proposed the relationship shown in the cladogram below, and provided names in "Gymnosphaera" for species they considered to belong in this genus.Older sources, such as the New Zealand Organisms Register and Large and Braggins (2004), place "Alsophila" within a broadly defined "Cyathea".The Pteridophyte Phylogeny Group classification of 2016 (PPG I) accepts the genus "Alsophila" with 275 species.
