Abstract: | A syntaxonomical study of Italian wall vegetation based on classification and ordination of a large phytosociological data set from various authors (using the IAHOPA program) has confirmed the alliances Centrantho-Parietarion and Galio-Parietarion (order Parietarietalia judaicae, class Parietarietea judaicae), as already proposed by traditional syntaxonomy. The variation in humidity and the north-south geographical gradient are shown to be the most significant factors for the differentiation of this vegetation in Italy. The presence of some associations belonging to the class Asplenietea trichomanis (alliance Cystopteridion, Potentillion caulescentis and Centaureo-Campanulion) shows a strong connection with natural rock vegetation. |
