( 2 ) Delphinium menyuanense,described from Qinghai Province and related to D. pylzowii Maxim.,differs in its very short stem,racemose inflorescence,and undivided limbs of staminodia. ( 3) Clematis yuntaishanica,described from Henan Province,and related to C. parviloba Garden. & Champ.,differs in its bipinnate leaves,smaller flowers,and black,nerveless filaments of stamens. ( 4) Clematis melanonema,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) Ranunculus wutaishanicus,described from Shanxi Province and similar to R. glareosus Hand. -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) Clemartis jingxiensis,is described as new from Guangxi Zhuang Autonomous Region. It is related to C. 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.
