Abstract: A species of the genus Ranunculus (Ranunculaceae) is described as new from Anhui Province. This species
is closely related to R. ternatus Thunb.ꎬ and from the latter differs in its filiform stolen with small root tubersꎬ 2 ̄foliolate
lateral leaflets of ternate basal leafꎬ and the styles of carpels which are slightly shorter than or as long as ovaries.
