A syntaxonomical revision of the associations belonging to the class Saginetea maritimae occurring in the Italian territory, is given. They are therophytic, halo-subnitrophilous communities, occurring during springtime, in coastal places, such as rocky coasts and salt marshes as well as in the inland badlands. They are widespread in the territories of the Mediterranean area and Temperate Atlantic Europe, where they constitute a mosaic with the perennial communities of Crithmo-Limonietea, Juncetea maritimi, Sarcocornietea fruticosae, Lygeo-Stipetalia and Agropyretalia repentis. In the Italian territories with a temperate bioclimate, this class is represented by the order Saginetalia maritimae, with the only alliance Saginion maritimae, while in those ones with a mediterranean bioclimate, this order is vicariate by Frankenietalia pulverulentae, within it is possible to distinguish three alliances; they are Frankenion pulverulentae, widespread in the salt-marshes and along the rocky coasts, Limonion avei, replacing the previous one in markedly thermo-xerophilous environmental conditions, and Gaudinio-Podospermion cani, linked to clayey places of inland badlands. All the associations have been examined from the nomenclatural, floristical, ecological and chorological point of view.
