From: Cytotype diversity and genome size variation in Knautia (Caprifoliaceae, Dipsacoideae)
Flow cytometry histograms showing genuine differences in relative genome size. Histograms showing differences within ploidy levels of Knautia (a–b) and the divergent relative genome size of the Iberian taxa, exemplified by tetra- and hexaploid K. rupicola (d). a diploid Knautia drymeia (K040, right) and K. lebrunii (K408, left). b Tetraploid K. nevadensis (K405, right, and K406, left). c Hexaploid K. dipsacifolia (K029, right, and K038, left). d From left to right: diploid K. drymeia (K039), tetraploid K. dinarica (K028) and K. rupicola (K400), hexaploid K. ressmannii (K449) and K. rupicola (K402)
