We confirmed hybridization between the diploid species C. ficifolium and C. suecicum using highly variable nuclear microsatellite markers. Analysis of variation in microsatellite loci using Bayesian methods, PCoA and Neighbour-joining tree identified 32 F1 hybrids out of 480 sampled individuals. These F1 hybrids, described as C. paradoxum Mandák, formed a cluster between well differentiated parental species, combining the morphological characters of both their parents. Moreover, genetic analyses also recognized several F2 or backcross hybrids, whose delimitation, mainly from C. suecicum and F1 hybrids, based on morphological characters, is problematic.
