Rodgersia nepalensis T. A. Cope ex Cullen was recorded from Xizang by Pan (in C. Y. Wu, Fl. Xizang. 2: 517-518. 1985). This species might well occur in W Xizang, but no specimens from China have been seen by the present authors; further study is required.
Five species: E Asia, Himalayas: four species (two endemic) in China.
