SYMPATRIC POPULATIONS OF SENECIO-OVATUS SUBSP OVATUS, SENECIO-GERMANICUS SUBSP GERMANICUS (COMPOSITAE) AND THEIR HYBRID IN THE CARPATHIANS AND THE ADJACENT PART OF PANNONIA .2. SYNECOLOGICAL DIFFERENTIATION AND DISTRIBUTION

A synecological study of two sympatric taxa - S. ovatus subsp. ovatus and S. germanicus subsp. germanicus, based on 49 releves, made during years 1987-1993 in the Carpathians, is presented. Numerical classifica tion (cluster analysis) and ordination (principal components analysis, PCA), were used. Existing published releves obtained from representat ive phytocoenological tables from the region studied were compared to the results of the numerical classification and ordination. S. germani cus subsp. germanicus was encountered in the whole Carpathians and pre fers sunny or semi-shady mesophilous or subxerophilous places (e.g. na tural forest fringes) of the submontane and montane belt. S. ovatus su bsp. ovatus and S. x futakii (S. germanicus subsp. germanicus x S. ova tus subsp. ovatus) is distributed mainly in the West Carpathians in sh ady, semi-shady mesophilous or hygrophilous places of the submontane a nd montane belt.
