On gentle eastern slopes of Psunj, dry grasslands are developed. Dry grasslands represent one of the most endangered forms of vegetation, and were the subject of this research. The terrain is slightly sloping towards the southeast, southern exposure, altitude about 400 m. The aim of the research was to determine the abundance and variety of vascular flora of grasslands in Rudine area. Floristic research was conducted in 2003, 2008, 2016 and 2017. On the surface of about 2500 m2, a list of plant taxa has been compiled and determined by their affiliation with families, floral elements and life forms.One hundred and eighty-six vascular plants of 46 families and 134 genera were recorded. Taxonomic, ecological and phytogeological analysis was carried out. Taxonomic analysis suggests there are 2 species of gymnosperm (1.08%), 155 species of dicotyledons (83.33%), and 29 species of monocotyledons (15.59%). The analysis of life forms shows that the most represented are 113 species of hemicryptophytes (60.75%), and 29 species of terophytes (15.59%). Plants of the Eurasian floral element with 63 species (33.87%) and plants with a wide spread of 38 species (20.43%) dominate in phytogeographic analysis. The phytocenological analysis of floristic composition shows that these grasslands are a transient position between the Festuco-Brometea and Molinio-Arrhenatheretea classes, that is to show the transition between Festucetalia valesiacae, Brometalia erecti and Arrhenatheretalia.
