TWO NEW ASSOCIATIONS OF ROADSIDE VEGETATION FROM ABRUZZO (CENTRAL lTALY). This study describes the perennial nitrophilous and meso-igrophilous vegetation, occurring along the main roads of Abruzzo up to 900 m a.s.l. Two roadside phytocoenoses are described, one with Senecio inaequidens and the other with
Plumbago europaea. They are attributed to two new associations of the Artemisietea vulgaris class, Artemisia absinthii-Senecionetum inaequidentis, belonging to the Dauco-Melilotion alliance (Onopordetalia acanthii arder) and Galio albi-Plumbaginetum europaeae, belonging to the Inulo viscosae-Agropyrion repentis alliance (Agropyretalia repentis arder).
