Abstract
Phytosiciological identification of some meadow formations of the hill territory around Ancona - A phytosociological study of some meadow formations found in the hill territory near the city of Ancona in the Marches region, is presented. Two new associations of meso-hygrophilous meadows are described. These associations are related respectively to the climactic series of the peliticousarenaceous substrata (Asparago acutifolii-Ostryeto carpinifoliae sigmetum) and to the edaphous-hygrophilous substratum of the recent alluvial terraces (Symphyto bulbosi-Ulmeto minoris sigmetum): Senecio erucifolii-Inuletum viscosae and Pastinaco urentis-Arrhenatheretum elatioris. The marked presence of mediterranean species allows both the associations to be distinguished from analogous associations spread throughout the other areas of Europe having a temperate climate. In addition, the new submediterranean alliance Inulo viscosae-Agropyrion repentis is proposed, uniting the post-cultivation associations of the marly-arenaceous and argillaceous lands of the Apennines. The syntaxonomical synthesis and desription of the latter are presented.
