Sori linear, along segment margins, absent at apex and sinuses; indusia gray-brown or brown, linear, membranous, persistent.

Old World tropics and subtropics, Pacific islands; 35 species (20 endemic) in China.

It has not been possible to obtain a reliable estimate of the sizes of the sections within Pteris because there are no accounts consistent across the entire range.

Some species are calciphilous and can be found on limestone and walls.
