Ranunculus muricatus, a native of Europe, grows 15-50cm tall and is found in damp places, such as paths between paddies. Stems are sparsely branched at the bases, and radical and on-stem leaves are cleft in three and have serrated margins. Alternate phyllotaxis is leaves on the upper parts of the stems. Yellow, 5-petaled, 1.5cm in diameter flowers are placed singly at leaf axils on the upper portions. Fruit resulted in an aggregation of as many as 20 achenes. Bloom time: April-June.
