Notes on the wall vegetation of the Lake Garda surroundings (North Italy) and its consequences to the syntaxonomy of Tortulo–Cymbalarietalia Segal 1969

The paper discusses the differentiation of the wall plant communities occurring in the vicinity of Lake Garda (North Italy), between the cities of Lazise and Torbole. Three associations have been recorded: Linario cymbalariae-Parietarietum ramiflorae Pignatti 1952, Linario-Erigeronetum mucronati Segal 1969, Oxalido-Parietarietum judaicae (Br.-Bl. 1952) Segal 1969, and community with domination of Asplenium ceterach. The results can indicate that some of the associations distinguished by Brullo & Guarino (1998) in their pan-European synthesis do not exist as separable units.
