Ranunculus muricatus is a native of Europe, 15-50cm in height, found in damp places like paths between paddies, etc. Stems sparsely branch at the bases, and both radical and on-stem leaves are cleft in three and margins serrated. Of alternate phyllotaxis are leaves on the upper parts of the stems. Flowers, yellow, 5-petaled, 1.5cm in diameter, singly place themselves at leaf axils on the upper portions. Fruit resulted in an aggregation of as much as 20 achenes. Bloom time: April-June.
