We present here a syntaxonomic revision of the vegetation of the badlands of the Northern-Central Apennines. Badlands are argillaceous-pelitic areas that are affected by processes of rapid soil erosion, caused by the surface water. After a summary of previous studies and of the syntaxonomic schemes used, we present the methodology used for this study, which provides comparisons between phytosociological tables. We conclude that the perennial vegetation of the calanchi should be referred to the class Artemisietea, of the order Agropyretalia repentis and the alliance Inulo viscosae-Agropyrion repentis, within which it is possible to recognise the suballiances Inulo viscosae-Agropyrenion repentis of the non-halophilous aspects, and Podospermo laciniati-Elytrigenion athericae specifically for the more halophilous conditions of the more pioneering aspects of the vegetation. The annual vegetation can instead be included in the class Saginetea maritimae, of the order Frankenietalia pulverulentae and the alliance Hordeion marini. For each association, a brief description and a distribution map are included.
