Taxonomical and chorological diversity of native woody flora of Italy at regional scale.

This study aims at describing the taxonomical (at species and genus ranks) and chorological diversity of native woody flora of Italy, comparing with phytoclimatic and biogeographic complexity. After providing the most recent data about the native woody flora of Italy, the analysis has been performed at the level of political region. Cluster analisys shows that woody genera are the most effective variables to outline phytogeographical subdivisions, while chorological spectra provide more information in climatic terms
