This sedge with a Mediterranean-Atlantic distribution is present in all regions of Italy except in Valle d'Aosta. It grows in wet meadows, sometimes even on saline soils, from sea level to about 600 m. The species is common in the outer and intermediate belts of the Sardinian temporary ponds. The genus name derives from the Greek 'keiro' (to cut), because of the sharp edges of the leaves of some species. Flowering period: April to June.

Italian name(s): Carice divisa (Italia), Carice scirpina (Italia).
