THE OSTRYA CARPINIFOLIA SCOP. ON THE COASTAL ZONE OF THE MARCHE (CENTRAL ITALY). Ostrya carpinifolia has been found along the coast of the Marche, this species is present in the appice at Monte Conero in the southern part of Ancona and in a few wood formations in the vicinity of the coast. These wood formations in this particular work belong to the Ostryo-Quercetum ilicis Trinajstić and the Asparago (acutifolii) - Ostryetum carpinifoliae as a new association.
In the North-Eastern part of Monte Conero, the Ostryo-Quercetum ilicis association is present in a new sub-association known as aceretosum obtusati. Among the species that differentiate this new subassociation are: Acer obtusatum, Cephalanthera longifolia and Melittis melissophyllum. It has also been noted that above the altitude of 300m a variant that is particularly mesophilous with Hepatica nobilis and Mercurialis perennis is found.
The Asparago (acutifolii) - Ostryetum carpinifoliae is a new association in the order Quercetalia pubescentis and the local characteristic species are Asparagus acutifolius, Buglossoides purpureo-coerulea and Smilax aspera; a large number of these species that belong to the class of Quercetalia ilicis and constantly found in these forest formations assume a differential significance in respect of the association Scutellario-Ostryetum Pedrotti, Ballelli and Biondi of the internal zone of the Appennini.
