Gymnosphaera

provided by wikipedia EN

Gymnosphaera is a genus of tree ferns in family Cyatheaceae.

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]

Phylogeny

As of January 2023, the following species are accepted in the genus as currently circumscribed by the Checklist of Ferns and Lycophytes of the World:[5]
