Pleopeltis is a genus of between 20–50 species of ferns, widely distributed in tropical regions of the world, and also north into temperate regions in eastern North America and eastern Asia.[1][2][3]

The genus is closely related to Polypodium, and many of the species have been or sometimes are still included in that genus; further changes in the circumscription of the genus are expected as research continues.[2]

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.[2]
