A phytosociological study was done of Laurus nobilis woodlands in Sicily. The analysis, based on 18 relevés, supportsthe definition of a new syntaxon (Acantho mollis-Lauretum nobilis ass. nov.), considered as a vicariant of similar vegetationaspects described in other Mediterranean areas (Iberian and Italian peninsulas). The study mainly includes some unpublishedsites where polycormic individuals of laurel, sometimes reaching 13-15 meters in height, dominates the tree layer. Thisvegetation is also characterized by some laurophyllous species (Hedera helix, Rhamnus alaternus, Smilax aspera and sometimesViburnum tinus) and lianas (Rubia peregrina var. longifolia, Asparagus acutifolius, Tamus communis, Clematisvitalba, Calystegia sylvatica and Rubus ulmifolius), while in the undergrowth comprises particularly various broadleavedelements such as Cyclamen hederifolium subsp. confusum, and Acanthus mollis subsp. mollis, both included in the characteristicspecies combination together with Pistacia terebinthus and Orobanche hederae. The coenosis is typical of thehumic soils, often rich in lithic components, of shaded ravines and peririparian environments, in the thermo- and mesomediterraneanthermotype (Mediterranean pluviseasonal oceanic bioclimate). In view of the relictual status of this vegetation- also included as a "Priority Habitat" in Council Directive 92/43/EEC - we underline the need for a suitable protectionand conservation of these small, fragmented and isolated patches.Keywords: Laurus nobilis matorral, Quercetea ilicis, Mediterranean region, relic vegetation.
