| Abstract: | Peristylus is a genus of over 60 species, mainly distributed in the Old Worldtropics, with many species extending northwards to central China. In the present paper, thetaxa of the genus hitherto recorded in China are taxonomically and phytogeographically discussed and revised, and, as a result, 20 species are recognized, including one new species, P.jinchuanicus K. Y. Lang, and four new combinations, P. bulleyi (Rolfe) K. Y. Lang, P. forrestii (Schltr.) K. Y. Lang, P. longiracemus (Fukuyama) K. Y. Lang and P. neotineoides(Ames et Schltr.) K. Y. Lang. A full list of synonyms is given, a key to the species is provided and the distribution areas in China of all the taxa are mapped. |
