Abstract: The genus Adiantum L. of China was monographically treated over twenty years ago by R. C. Ching (Acta Phytotax. Sin. 6:348-454 1957). Since then new materials have been collected by botanical institutions in different provinces of China. In connection with the work of the Flora of China Project, the present paper aims primarily to make some new additions to our knowledge of the genus in China and also some necessary nomenclatural and toxonomical corrigenda to the previous literature citations involved. The writer wishes to express thanks of gratitude to Professor R. C. Ching for his encou-ragement and constant guidance during the course of the work.
