This paper presents a new sintaxonomical scheme for Quercetalia pubescenti-petraeaeQuercetalia pubescenti-petraeae order occurs in the study area in the form of five alliances: Quercion pubescenti-petraeae (suball.: Buxo-Quercenion pubescentis), Carpinion orientalisCampanulo-Ostryenion, Laburno-Ostryenion stat. nov.; Lauro-Quercenion pubescentis and Cytiso-Quercenion pubescentis), Teucrio siculi-Quercion cerridis nom. conserv. propos. (suball.: Teucrio-Quercenion cerridis suball. nov., Ptilostemo-Quercenion cerridis); Pino-Quercion congestae (suball.: Pino-Quercenion congestaeQuercenion virgilianae suball. nov.) and Erythronio-Quercion petraeae. The Quercion pubescenti-petraeae is a sintaxon with a sub-continental character and within the Italian Peninsula it is restricted to Ligurian-Piedmontese Apennine in the form of the sub-alliance Buxo-Quercenion pubescentis. Carpinion orientalis is a sintaxon with oceanic/suboceanic features, which is widely distributed along the entire Italian Peninsula. It occurs mainly on limestone substrates forming woodlands which can be potential vegetation types and also woods of secondary origin and evolution. The Teucrio-Quercion cerridis is an alliance which is widely distributed within central and southern Italy, where it finds its coenological optimum on acid, subacid or neutral substrates such as volcanic outcrops, flysch, sandstones or clayey-arenaceous sediments. In this alliance are included both thermophilous Quercus cerris and Quercus petraea woodlands of Tuscany, Umbria and northern Latium, together with Quercus cerris and Quercus frainetto woodlands of southern Italy. The alliance Pino-Quercion congestae is restricted to Sicily and southern Calabria, and includes Quercus virgilianaQ. dalechampii hilly woodlands, and also sub-montane and lower-montane Quercus congesta woods. Finally, Erythronio-Quercion petraeae behaves as a typical mesophilous and microthermic alliance which exhibits clear biogeographical similarities with towards the central-european woodlands. This alliance is restricted to the northern Apennines where it is in geo-serial contact with Carpinion betuli, Quercion robori-petraeae and Fagion woodlands.
