Plant generally in soil; rhizome erect or short- to long-creeping, scaly or hairy.
Leaf: generally alike, 1–4- pinnate, erect-arched; stipe, axes grooved adaxially, grooves from rachis to costa connected; pinnules on basal side of lowermost pinnae more developed (except Pteris vittata).
Sporangia: among hair-like structures in continuous, marginal bands; false indusia along segment margins except at bases, tips, and between lobes, partly covering sporangia, scarious.
± 250–300 species: generally tropics, subtrop. (Greek: feather, for pinnae, or ancient name for ferns in general) Popular in cultivation.
