abstract

The class Rhamno-Prunetea in Italy. This paper deals with scrubs and thickets (pre-mantels, mantels and hedgerows) which are distributed mainly in Central and North-eastern Italy, from the meso-mediterranean belt of the Mediterranean region to the supra-mediterranean variant of the Temperate region. The presence of several stenomediterranean species and of a group of south-eastern species differentiates these coenoses from those of Central Europe. In Italy the Prunetalia spinosae Tuxen 1952 order is represented by the following alliances and sub-alliances: Cytision sessilifolii Biondi 1988, Berberidion vulgaris Br.-B1. 1950 (Berberidenion Géhu, Foucault et Delelis-Dusollier 1983 and Fraxino orni-Berberidenion Poldini et Vidali 1995), Pruno-Rubion ulmifolii O. Bolòs 1954 (with the unique suballiance Rubenion ulmifolii) and Salici-Viburnion opuli (Passarge 1985) De Foucault 1992.
