The Polish part of Śnieżnik Massif and Góry Bialskie Mts (50°06'-50°24'N/16°38' -17°02'E) were floristically investigated. The explored area totalled to about 390 km². A check list of 1032 spontaneous (both native and established alien) taxa of vascular plants was prepared based on the literature from 19th and 20th century as well as on extensive field research carried out in the years 1987-1989 and 1991-1993. Horizontal and vertical distribution of these species was graphically presented using 1 km-square grid map and a graph. Altogether 28067 separate records for horizontal and 31677 for vertical distribution diagrams were taken into consideration. 83 taxa from the literature have not been found; 458 species not published to date were discovered instead. The common features of the flora of the Śnieżnik Massif and the Jeseniky Mts, support including both ridges into one phytogeographical district of East Sudety Mts.
