Taxonomy
The genus was originally described by Carl Ludwig Blume in 1828.[1] It was frequently treated by later authors as a synonym of Cyathea or Alsophila.
In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), Gymnosphaera was left as a synonym of Alsophila, as evidence to support its reliable separation was lacking.[2] More recently, Shi-Yong Dong and collaborators proposed the revival and recircumscription of the genus based on additional phylogenetic evidence,[3] an act subsequently accepted by other tree fern workers.[4]
