abstract

The nitrophilous fringes of Galio-Urticetea class in the Lombard Prealps (N-Italy). We present the results of phytosociological study of the nitrophilous fringes, characterized by exotic species, found in Lombard Prealps area. Based on 30 releves, elaborated with cluster analysis, we describe two new associations (Impatientetum parviflorae and Potentillo indicae-Fragarietum vescae),and a new subassociation impatientetosum balfourii of the Circaeetum lutetianae association. We also describe ecology of these communities and their syndynamic relationships. As a completion of the report hereafter is the syntaxonomic scheme of the communities under.
