This buttercup is endemic to Sardinia and Sicily. It grows in wet meadows and on the margin of woods, on fresh soils, from sea level to about 800 m. In the temporary ponds of Sardinia this species is extremely rare. The whole plant is toxic for the presence of an alkaloid (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 refers to the habitat. Flowering period: April to June.

Italian name(s): Ranuncolo dei prati (Italia), Ranuncolo pratense (Italia).
