Abstract

Correlations between morphological variability, chromosome numbers and habitat conditions were studied in 31 populations of the Carex flava agg. in Bulgaria and Czechoslovakia. The following taxa were included: C. flava L. var. flava, C. flava var. alpina KNEUCKER, C. lepidocarpa TAUSCH, C. tumidicarpa ANDERSS. and C. serotina MÉRAT. Within and between population variability were compared in each taxon. The main source of the variability of individual taxa is the intrapopulational variation of large populations of the species that are not fully genetically isolated from each other in the regions studied.
