Genome size (2C) estimates from flow cytometry for all individuals in this study, for C. perfoliata, C. parviflora and C. rubra. Symbols depict ploidy status as determined by direct chromosome counts, or whether values are from individuals without direct chromosome counts. Note the overlap in genome size between hexaploids and octoploids among individuals, preventing clear determination of ploidy from flow cytometry at these ploidy levels.
