Polypodioideae is a subfamily belonging to the fern family Polypodiaceae. The subfamily name Polypodioideae has two recent uses. The first by Mabberley, 2008, included a larger group of polygrams, (said to possess scales and/or hairs; never stellate), which included six tribes, one of which, Polypodieae, is considered to be a synonym of the more recent sense of Polypodioideae by Christenhusz et al., 2011, in which Polypodiaceae contains five subfamilies, including the smaller Polypodioideae subfamily.
Mabberley, in 2008, defined this subfamily in a very broad sense, including all of Polypodiaceae except for the Platycerioideae (Platycerium and Pyrrosia) and the grammitid ferns, which he placed in Grammitidaceae. He distinguished this subfamily from the platycerioids by the absence of stellate hairs on the fronds. He subdivided it into six tribes, Drynarieae (fronds dimorphic; Aglaomorpha and Drynaria), Selligueeae (fronds monomorphic, with opaque scales on the stem; Selliguea), Lepisoreae (fronds monomorphic, with clathrate scales and thick exospore; Belvisia and Lepisorus), Microsoreae (fronds monomorphic, with clathrate scales and thin exospore), Polypodieae (Pecluma and Polypodium), and Loxogrammeae (lacking internal sclerenchyma above roots; Loxogramme).
