This buttercup is endemic to the Sardinian-Corsican System. The life-cycle can be spent part in water, part on moist to dry soil. It grows in temporary ponds, along ditches, in marshy places, from 700 to 1600 m. It is a characteristic species of the Mediterranean temporary ponds of Sardinia, mainly occurring in the intermediate belt. The species is indicated in the Regional Red Lists as critically endangered (Conti et al., 1997). 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, from the Latin 'cor-cordis' (heart) refers to the basal leaves that have a heart-shaped base. Flowering period: June to July.

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