Two new ruderal plant communities belonging to the order Onopordetalia are described from southern Slovakia. The Cerintho-Vicietum villosae (Dauco-Melilotion) populates nutrient-poor disturbed soils at road verges and slopes in wine-growing regions of the Male Karpaty Mts. It is typified by numerous Fabaceae. The community was also found in southern Styria (Austria). The Sisymbrio orientalis-Xeran-themetum annui (Onopordion) is another thermophilous ruderal community characteristic of loess-covered slopes flanking roads in the warmest regions of southern Slovakia.
