abstract

The Genista radiata (L.) Scop. var. sericopetala Buccheger communities in the western Italian Alps. Results of a phytosociological study on Genista radiata (L.) Scop. var sericopetala Buccheger communities in Lepontine, Pennine and Graie Alps (Italy) are herein presented. The studied area is located in the northern district of Piedmont and AostaValley, under the influence of subatlantic climate. The vegetation study has been performed throught 29 phytosociological relevés. All data were submitted to multivariate statistical analysis. The vegetation was classified into the association Phyteumato scheuchzeri-Genistetum radiatae ass. nova (alliance Rhododendro-Vaccinion), located in the subalpine bioclimatic belt, upon to the beech forest line. Three subassociation have been recognized: typicum subass. nova, brachypodietosum caespitosi subass. nova and ericetosum carneae subass. nova. Chorological, synecological and syndynamical data were described in the paper.
