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 spe-

cies is described as new.

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