SYMPATRIC POPULATIONS OF SENECIO-OVATUS SUBSP OVATUS, SENECIO-GERMANICUS SUBSP GERMANICUS (COMPOSITAE) AND THEIR HYBRID IN THE CARPATHIANS AND THE ADJACENT PART OF PANNONIA .1. MULTIVARIATE MORPHOMETRIC STUDY

A multivariate morphometric study of Senecio germanicus subsp. germani cus, Senecio ovatus subsp. ovatus and their hybrid, Senecio x futakii ii based on 19 population samples, collected throughout the Carpathian s in Slovakia, Ukraine and Romania, is presented. Multivariate methods used include principal components analysis, cluster analysis, classif icatory and canonical discriminant analysis. As a complementary eviden ce, the hybrid indices were calculated. In spite of possible problems in classification of certain plants into ''pure'' types or hybrids, th e existence of parental species and hybrids in the area studied was pr oven.
