Abstract: Dichroa Lour., a small genus of Saxifragaceae, contains about 12 species, ranging from the mainland of S. E. Asia southward to Pacific islands. But most of the species are more restricted in distribution. Of the 12 recognized species, six are known from South China and Indochina; three are confined to west and northwest New Guinea; two are endemic to the Phillipines. Only one species is widely distributed in S. E. Asia. In the present paper, the genus is divided into two sections and two series based on the number of stamens and the characteristics of the ovary. One species is described as new.

Key words: Dichroa, D. yunnanensis, new section, new series
