Pleopeltis is a genus of ferns in the family Polypodiaceae, subfamily Polypodioideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I).[2] The genus widely distributed in tropical regions of the world, and also north into temperate regions in eastern North America and eastern Asia.[3][4][5] Several species are known by the common name scaly polypody and resurrection fern.[6]
The genus is closely related to Polypodium. Many of the species have been or sometimes are still included in that genus. Further changes in the circumscription of the genus may occur as research continues.[4]
They are epiphytic, epipetric (growing on rocks), or rarely terrestrial ferns, with a creeping, densely hairy or scaly rhizome bearing fronds at intervals along its length. The fronds are evergreen, persisting for 1–2 years, and are entire or deeply pinnatifid. The sori or groups of spore-cases (sporangia) are borne on the back of the frond.[4]

Pleopeltis (latin: Pleopeltis) er en slekt av bregner innen sisselrotfamilien, som tilhører ordenen Polypodiales.[1]
De fleste av de minst 35 artene er oppreiste og moderat store. Slekten anses noen ganger som en underslekt under Polypodium (Sisselrotfamilien).
Slekten Pleopeltis har stort sett habitater i Sør-Amerika, men også noen få arter i Afrika, Asia og Stillehavet.
