This paper supplements the treatment of the genus Potentilla in China beyond the Flora Reipublicae Popularis Sinicae (Yü and Li, 1985) and the partly revised English edition Flora of China (Li et al., 2003). The present remarks concern taxonomic problems of rather difficult groups of species; generic delimitation; the names of sections, species, and varieties, and their descriptions and distributions; and identification keys. Yü and Li (1985) dealt with 83 Chinese species of Potentilla. In the present paper, another 30 species growing in China are added. Most remarks and supplements here refer to the partly revised English edition by Li et al. (2003).
