The "guazzi" vegetation and the plant landscape of the alluvial plane of the last stretch of the Musone River (Central Italy). The phytosociological study of the "guazzi" vegetation and the plant landscape of the last stretch of the Musone River alluvial plane is here presented. The "guazzi" are little artificial wet areas, made and kept for hunting reasons. The structural and managerial characteristics, as well as the environmental conditions of these formations, are described. The floristic research allowed to register 165 entities divided into 49 families and 116 genera. They are generally common species of anthropic and ruderal areas while some of them have a certain interest for the regional flora. These species are mainly found within the "guazzi" which therefore contribute considerably in the increase of biodiversity of the examined territory. The phytosociological study allowed the identification of several syntaxa, mainly connected to "guazzi", some of which are described for the first time: Crypsido schoenoidis-Juncetum bufonii ass. nova; Loto tenuis-Paspaletum paspaloidis ass. nova; Trifolio fragiferi-Ranunculetum ophioglossifolii ass. nova; Eleocharitetum palustris Schennik 1919 paspaletosum paspaloidis subass. nova; Bolboschoenetum maritimi Eggler 1933 lotetosum tenuis subass. nova, Senecio erucifolii-Inuletum viscosae Biondi & Allegrezza 1996 lotetosum tenuis subass. nova.
