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
