Abstract: Five species belonging to four generaꎬ Aconitumꎬ Delphiniumꎬ Clematis and Ranunculus respectively (Ranun ̄
culaceae) are described as new from China: (1) Aconitum tuolienseꎬ being described from Xingjiang Uygur Autonomous
Region and related to A. smirnovii Steinb.ꎬ and differing in its glabrous stem and leavesꎬ very dense racemeꎬ and mostly
1 ̄2 ̄denticulate filaments of stamens. (2) Delphinium menyuanenseꎬ being described from Qinghai Province and related
to D. pylzowii Maxim.ꎬ and differing in its very short stemꎬ racemose inflorescenceꎬ and undivided limbs of staminodia.
(3) Clematis yuntaishanicaꎬ being described from Henan Provinceꎬ and related to C. parviloba Garden. & Champ.ꎬ and
differing in its bipinnate leavesꎬ smaller flowersꎬ and blackꎬ nerveless filaments of stamens. (4) Clematis melanonemaꎬ
being described also from Henan Province and closely related to the above new speciesꎬ C. yuntaishanicaꎬ and differing
in its smallerꎬ narrowly ovate or lanceolate leafletsꎬ and smallerꎬ usually 3 ̄flowered cymes. (5) Ranunculus wutaishani ̄
cusꎬ being described from Shanxi Province and similar to R. glareosus Hand. ̄Mazz.ꎬ and differing in its pubescent basal
leavesꎬ nectary pit of petal with a scaleꎬ and carpel with a short and thick style and a minute stigma.
