Species boundaries and frequency of hybridization in the Dryopteris carthusiana (Dryopteridaceae) complex: a taxonomic puzzle resolved using genome size data

Abstract

The study shows that genome size is a powerful marker for taxonomic decisions about the D. carthusiana complex and that genome size data may help to resolve taxonomic complexities in this important component of the temperate fern flora.
