abstract

The woods of the hilly belt of Terni Province. On the grounds of 94 unpublished phytosociological relevés, carried out in the territory of Terni Province, a phytosociological arrangement of Quercus ilex, Ostrya carpinifolia, Quercus pubescens, Quercus cerris, Quercus frainetto dominated woods of hills and plains, is proposed. The territories where these vegetation types grow can be referred to the Mesomediterranean and Sub-Mesomediterranean belts.
The observed associations are: Ciclamino repandi-Quercetum ilicis, Fraxino orni-Quercetum ilicis, Rusco aculeati-Quercetum ilicis ass. nova, Cephalanthero longifoliae-Quercetum ilicis, Scutellario columnae-Ostryetum carpinifoliae, Asparago acutifolii-Ostryetum carpinifoliae, Roso sempervirentis-Quercetum pubescentis, Roso sempervirentis-Quercetum pubescentis subass. quercetosum dalechampii subass. nova, Lonicero xylostei-Quercetum cerridis, Erico arboreae-Quercetum cerridis, Cephalanthero longifoliae-Quercetum cerridis, Malo florentinae-Quercetum frainetto.
Each recognized syntaxonomical unit is presented through a floristic, biogeographic, geologic and bioclimatic characterization, in order both to define the ecology of each phytocoenosis and, in general, to improve the understanding of the biogeographic and bioclimatic complexity that characterizes this transitional territory of centra1 Italy, placed in the middle between the Adriatic and the Tyrrhenian slopes of the Italian peninsula.
