Two Carex serotina forms ('A' similar to forma serotina, 'B' similar to forma thalassica) occur together on the mud of a meander lake in the Tiszaalpar Basin. The distribution of the forms in space seems to be independent of the location of the cenological sample in the lake bed. The frequencies of dominance show a close paralellism in the 2-10 domain of dominance. The measures of association and correlation between the two forms refer to a close positive relation of the forms. According to our current information, it is the first paper in which such a degree of phenotypical variability increase is reported, which had led to the discontinuous segregation between two cooccurrent plant forms in a natural population
