What is "drynarioideae"

Drynarioideae is a subfamily of the Polypodiaceae family of ferns. It combines the drynarioid and selligueoid ferns, which have been considered to be tribes ( and ) of the Polypodioideae subfamily of Polypodiaceae, but recent molecular phylogenic analysis have placed them in a separate subfamily. The genus count of neither of original tribes was certain, but the combined total is probably at least nine.
