(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. (2)Delphiniummenyuanense， described from Qinghai Province and related toD.pylzowiiMaxim.， differs in its very short stem， racemose inflorescence， and undivided limbs of staminodia. (3)Clematisyuntaishanica， described from Henan Province， and related toC.parvilobaGarden. & Champ.， differs in its bipinnate leaves， smaller flowers， and black， nerveless filaments of stamens. (4)Clematismelanonema， described also from Henan Province and closely related to the above new species，C.yuntaishanica， differs in its smaller， narrowly ovate or lanceolate leaflets， and smaller， usually 3-flowered cymes. (5)Ranunculuswutaishanicus， described from Shanxi Province and similar toR.glareosusHand.-Mazz.， differs in its pubescent basal leaves， nectary pit of petal with a scale， and carpel with a short and thick style and a minute stigma. (6)Clemartisjingxiensis, is described as new from Guangxi Zhuang Autonomous Region. It is related toC.formosana, and from the latter differs in its sparsely puberulous stems, ovate or narrowly ovate and undivided leaflets, 1-3-flowered cymes, and in its larger sepals 1.7-2 cm long and 0.5-0.7 cm broad.
