Highest proportion of Querco-Fagetea, Fagetalia and Fagion sylvaticae species, lowest proportion of indifferent species (Table 4), high proportion of specialists and competitors (Table 5) are significant. This group can be identified with beech woodlands. Characteristic species: Fagus sylvatica, Oxalis acetosella. DISCUSSION Results of the multivariate analyses indicate that the phytosociological character of the plant species can be very useful at evaluation and characterizing of vegetation types. All methods performed on "matrix B" have provided more informative results than "matrix A". It means that the phytosociological character of the species can effectively concentrate the relevant information about the vegetation. The statistical analyses according to the characteristics of the associated plant species prove that the phytosociological and ecological range of Telekia speciosa is wide. Distribution of ecological indicator values varies in a wide range (Tables 6 to 11). Although T. speciosa is considered to be a Filipendulo-Petasition species (SOÓ 1980, BORHIDI 1993), it occurs in a number of different plant communities and vegetation types including disturbed and weedy vegetation.
