The present study confirmed the most recent taxonomic classification of European species of Bolboschoenus. Based on AFLP data, four genetic groups corresponding to the species were found. Correlations of important determination characters with genetic groups were detected using canonical discriminant analysis, which confirmed the importance of morphological and anatomical characters of achenes. We consider exocarp and mesocarp widths and achene shape in transverse section to be the most reliable characters for species determination. Hybrid origin of B. laticarpus was confirmed, with B. yagara and B. planiculmis as its parental taxa.
