    Description / Table of Contents: Zusammenfassung Populationen vonBecium homblei ciner Schwermetall toleranten Pflanzenart wurde in einigen isolierten Gebieten mit ganz verschiedenen Böden gefunden. Die Blütenform und das Gewicht der Samen als relativ nicht plastische Artenmerkmale wurden in vier Populationen studiert und die Resultate statistisch bearbeitet. Die größten Unterschiede ergaben sich zwischen Populationen ganz abweichender Bodentypen. Pflanzen von Schwermetall-Böden zeigten cine allgemeine Reduktion der Blütengröße. Es wird angenommen, daß die Resultate ökotypischen Variationen zwischen den Populationen entsprechen.
    Notes: Summary Populations ofBecium homblei, a metal tolerant plant species, were found to exist in a number of isolated areas in which the soil conditions were very different. Corolla shape and seed weight which are regarded as relatively implastic characters in the species were examined from four populations and the results subjected to a statistical analysis. The greatest differences were found between those populations which grew in widely different soil types. Plants on heavy metal soils showed an overall reduction in flower size. It is suggested that the results indicate ecotypic variation between the populations.
