The Italian distribution of this Mediterranean buttercup is limited to Sardinia and Tuscany. It grows in wet meadows and along the edges of ditches, rivers and waterways, from sea level to about 600 m. The species is found sporadically in the outer belt of the temporary ponds of Sardinia, in contact with hydric grasslands. The fresh parts are poisonous (protoanemonine). The genus name, the Latin for 'little frog', was used since ancient times only for the aquatic species of the subgenus Batrachion, also a diminutive of the Greek 'batràchos' (frog); the species name is derived from Greek and means 'with big leaves'. Flowering period: April to May.

Italian name(s): Ranuncolo macrofillo (Italia).
