A syntaxonomical revision of the class Querco-Fagetea sylvaticae in Sicily, based on literature data and unpublished relevés, is presented. this class groups the mesophilous woods characterized by the dominance of deciduous trees (e.g. Fagus sylvatica, Quercus sp. pl., Acer sp. pl.), and more rarely by conifers (Taxus baccata, Pinus nigra subsp. calabrica), as well as by other broadleaved trees, such as Betula aetnensis, Populus tremula, Castanea sativa. in Sicily, these woody communities are widespread in the northern and north-eastern districts of the island, chiefly on the highest peaks (madonie, nebrodi, peloritani, and etna). this class is represented in Sicily by two, both floristically and ecologically well differentiated orders: Fagetalia sylvaticae, with the sole alliance Geranio versicoloris-Fagion sylvaticae, and Quercetalia pubescenti-petraeae, with the endemic alliance Pino calabricae-Quercion congestae. on the whole, 22 associations have been recognized within the class Querco-Fagetea and for each of them nomenclature, floristic assessment, ecology, syndinamic relationships, and chorology are examined.

Abstract
A syntaxonomical revision of the class Querco-Fagetea sylvaticae in Sicily, based on literature data and unpublished relevés, is presented. this class groups the mesophilous woods characterized by the dominance of deciduous trees (e.g. Fagus sylvatica, Quercus sp. pl., Acer sp. pl.), and more rarely by conifers (Taxus baccata, Pinus nigra subsp. calabrica), as well as by other broadleaved trees, such as Betula aetnensis, Populus tremula, Castanea sativa. in Sicily, these woody communities are widespread in the northern and north-eastern districts of the island, chiefly on the highest peaks (madonie, nebrodi, peloritani, and etna). this class is represented in Sicily by two, both floristically and ecologically well differentiated orders: Fagetalia sylvaticae, with the sole alliance Geranio versicoloris-Fagion sylvaticae, and Quercetalia pubescenti-petraeae, with the endemic alliance Pino calabricae-Quercion congestae. on the whole, 22 associations have been recognized within the class Querco-Fagetea and for each of them nomenclature, floristic assessment, ecology, syndinamic relationships, and chorology are examined.
