(StateKeyLaboratoryofSystematicandEvolutionaryBotany，InstituteofBotany，ChineseAcademyofSciences， Beijing 100093， China )

Six species belonging to four genera，Aconitum，Delphinium，ClematisandRanunculusrespectively (Ranunculaceae) are described as new from China: (1)Aconitumtuoliense， described from Xingjiang Uygur Autonomous Region and related toA.smirnoviiSteinb.， differs in its glabrous stem and leaves， very dense raceme， and mostly 1-2-denticulate filaments of stamens.
