Citations of Pseudophegopteris paludosa (Blume) Ching from China (Ching, Acta Phytotax. Sin. 8: 315. 1963; Tsai & Shieh, Fl. Taiwan, ed. 2, 1: 401. 1994), a species known with certainty only from Malesia (Holttum, Blumea 17: 91. 1969; Fl. Males., Ser. 2, 1: 347. 1981), perhaps apply to specimens of P. pyrrhorhachis or P. hirtirachis, which are two closely related and similar species.
About 25 species: tropical and subtropical Asia, east to the Pacific islands, to the west reaching to W Africa; 12 species (four endemic) in China.
