Abstract
Based on field observation and extensive herbarium studies, a comprehensive taxonomic revision of the genus Pogostemon in China was carried out. Twenty-seven species and two varieties are recognized, among of which eleven species and one variety are endemic to China. A new species, P. henanensis, is described and illustrated. Two new combinations, P. glaber var. tsingpingensis and P. latifolius, are proposed. Six names are reduced to synonymy, eleven names are lectotypified and a name is neotypified. The record of P. menthoides in China is corrected as P. fraternus. One species, P. pressii, is listed as dubious species in China. In addition, nomenclature, descriptions and distribution maps of each species and variety as well as a key to Chinese Pogostemon taxa are presented.
