Twelve morphometric variables of Cardaminopsis halleri individuals from four sites in upper silesia province were analyzed to establish the pattern of interpopulational relations. Two hundred plants were collected from two very polluted areas (near zinc-lead and zinc smelters) as well as from two other sites in unpolluted areas within the same bioclimatic region. stem size, dimensions of leaves and rosettes, as well as flower and seed numbers and individual dry weights were studied using standard biometric methods. cluster analysis indicated overall differences among populations. Those four populations are different with respect to all variables. Discriminant function analysis confirmed seed number as the most important variable in the evaluation of interpopulational variability.
