The hemicryptophytic, chamaephytic and therophytic communities which inhabit the fixed sand dunes of the N-Adriatic coast, along with those of the interdunal wetlands, have been studied from the phytosociological point of view. The floristic-sociological analysis focuses on the syntaxonomic discussion of the xerophilous communities; in this context, the following new syntaxa have been described: Syntrichio ruraliformis-Lomelosion argenteae, Tortulo-Scabiosetum typicum and Sileno conicae-Avellinietum michelii. In regards to the dune slack vegetation, the study points out the occurrence in the coastal area of two rare inland microtherm communities (Plantagini altissimae-Molinietum caeruleae and Erucastro-Schoenetum nigricantis). As already stated in previous papers, the originality of this sector of the Mediterranean basin is highlighted as a result of both bioclimatic and phytogeographic factors, which confer to this area a unique character in the European context.
