With the help of flow-cytometric analysis of nuclear DNA content and morphology, we establish the presence in the Netherlands of two taxa of the Dryopteris affinis complex: diploid D. affinis subsp. affinis, triploid D. affinis subsp. borreri, and the hybrids D ×complexa (tetraploid) and D. ×critica (pentaploid).
