abstract

The floristic-sociological analysis of Fraxinus angustifolia subsp. oxycarpa-dominated woods coming from north-eastern Italy and the comparison with phytosociological tables of other Italian and Croatian communities, led to the description of two new associations respectively belonging to Carici remotae-Fraxinion oxycarpae (Salici purpureae-Populetea nigrae) and Frangulo alni-Fraxinion oxycarpae (Alnetea glutinosae): the floodplain/riparian Lysimachio nummulariae-Fraxinetum oxycarpae and the swampy Valeriano dioicae-Fraxinetum oxycarpae.
