A phylogenetically informed generic reclassification of the hemionitid ferns (Pteridaceae: Cheilanthoideae)
Journal Article TAXON · February 17, 2025 AbstractThe roughly 500 species of cheilanthoid ferns exhibit a diversity of morphological adaptations to xeric environments. However, most of these traits have evolved independently multiple times, impeding past efforts to ...
