THE WOOD COENOSES OF COLLI SERICI (VICENZA, NE lTALY). The syntaxonomical, chorological and ecological features of the wood coenoses occurring in the hilly area of Colli Berici (Vicenza, North-Eastern Italy) are described. Three associations are recognized: the suboceanic Omithogalo pyrenaici-Carpinetum Marincek et al. 1983, Buglossoido-Ostryetum Gerdol et al. 1982 em. Poldini 1988, which prefers more marked thermic excursions, and the synanthropical Lamio orvalae-Sambucetum nigrae Poldini 1980. The first association includes two coenoses: the gorge woods, characterized by species of Tilio-Acerion Klika 1955 and Lamio Acerenion Marincek I 990, and the subass. caricetosum pilosae Marincek et al. 1983. The Buglossoido Ostryetum is subdivided into two subassociations: typicum and pistacietosum terebinthi Poldini 1988. The latter is characterized by the presence of taxa of Quercetea ilicis Sr.-Sl. 1947 and by a higher incidence of species belonging to the the Mediterranean s.l. chorological type; its differential species are proposed. The marginal presence of two further associations (Melampyro vulgati-Quercetum petraeae s.lat. Puncer et Zupancic 1979 em. Zupancic 1994 and Carici umbrosae-Quercetum petraeae Poldini 1982) is hypothesized.
