(Received on November 6，2 004)
Several taxa of Rhodiola (Crassulaceae) were examined mainly based on the authen-
tic specimens. Rhodiola tangutica (Maxim.) S. H. Fu which has been often confused with
R. algida (Ledeb.) Fisch. & C. A. Mey. in the subgenus Crassipedes is well distinguished
by the dioecious nature and the combinations of several vegetative and f10ral characters，
and classified in the subgenus Rhodiola (sect. Rhodiola). The revised description is pro-
vided. The synonymy of Rhodiola krivochizhinii Sipliv. with R. rosea is discussed ag泊n
based on the examination of the type. Sedum trollii Werderm. is considered as the syno-
nym of Rhodiola pachyclados (Aitch. & Hemsl.) H. Ohba.
