About four species: subtropical lowland broad-leaved evergreen forests in SW China and one species extending to Guangxi and Taiwan, and Japan; four species (three endemic) in China.

Polystichum sect. Neopolystichum is tentatively recognized here pending more evidence. The relationship between P. sect. Macropolystichum and P. sect. Neopolystichum is unclear.
