rdf:langString Drynarioideae

rdf:langString Drynarioideae is a subfamily of the fern family Polypodiaceae in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). The subfamily is also treated as the tribe Drynarieae within a very broadly defined family Polypodiaceae sensu lato. In either case, it includes the previously separated tribe Selligueeae. Drynarioideae combines the drynarioid and selligueoid ferns, which have been considered to be tribes (Drynarieae and Selligueeae) when the family Polypodiaceae was very broadly circumscribed. The genus count of neither of original tribes was certain, but the combined total could be at least nine. The Pteridophyte Phylogeny Group classification of 2016 (PPG I) recognizes six genera. Other sources accept fewer. As of February 2020, the Checklist of Ferns and Lycophytes of the World (CFLW) sank Arthromeris, Paraselliguea and Polypodiopteris into a more broadly circumscribed Selliguea. Plants of the World Online in addition placed the sole species of Gymnogrammitis in Selliguea, and recognized Drynaria rather than Aglaomorpha. The table below summarizes these approaches.
