This contribution describes a new plant association of marshy meadows, named Deschampsio cespitosae-Caricetum buxbaumii ass. nova hoc loco, occurring in the karstic basins of Sibillini Mountains (Pian Grande, Pian Piccolo and Savelli-Castel S. Maria, Umbria Region) between 1000-1350 m above sea level. The new association is distinguished from Ranunculo-Caricetum buxbaumii Pedrotti 2016 and Galio palustris-Caricetum buxbaumii Ciaschetti & al. 2020 for its floristic and ecological features. After the comparison with the original tables of Issler's Caricetum buxbaumii and Ritter-Studnicka’s Valeriano-Caricetum buxbaumii, all Apennine associations belong to Caricion gracilis alliance, and are southern synvicariants of the Caricetum buxbaumii Issler 1933 of Central Europe.
