THE VEGETATION OF MEADOWS AND OVERGRAZED PASTURES (ARRHENATHERETALIA AND POO-TRISETETALIA) IN FRIULI (NE ITALY). The vegetation of mowed meadows in Friuli is described and compared with similar coenoses of the Karst area near Trieste. According to Ellamuer and Mucina (1993). We include the meadows of the plains into the order Arrhenatheretalia s.s. and the mountane ones into the order Poo-Triesetetalia.
The association Centaurea carniolicae-Arrhenatheretum Oberdorfer 1964 is reviewed, and the new, corrected name Centaurea carniolicae-Arrhenatheretum is proposed. Tue old name Anthaxantha-Brametum Poldini 1980 is restored for the Karst coenosis dominated by the same species. A new association (Poo
sylvicolae-Lalietum multiflori ass. nov.) is described for damp meadow; although it belongs lo the alliance Arrhenatherian, many species from the Balcanic-Submediterranean alliance Trifalia-Hordeion Horvatic 1934 are
present. In Friuli Poo-Trisetetalia includes three alliances: Palygana-Trisetian, Poion alpinae and Alchemillo-Poion supinae. The first one includes Centaurea transalpinae-Trisetetum nom. nov., association of meadows of mountain belt in the Southern Alps. A new association, Crepida-Paetum alpinae ass. nov., replaces Crepidao-Festucetum rubrae Liidi 48 in the Southeastem Alps. The basal-phytocoenon with Deschampsia caespitosa and Veratrum album/lobelianum belongs to the alliance Poion alpinae. Only Alchemilla-Poetum supinae Aichinger 33 represents the alliance Alchemilla-Paian supinae.
