Boxplot representing range of genome sizes (in picograms) of species of Kaempferia subg. Protanthium in Thailand based on 84 accessions (276 individual plants) from 15 species and one variety. Lines extending from boxes (whiskers) indicate variability outside upper and lower quartiles. Different letters above each box indicate statistically significant difference between means of genome sizes (p <0.05). – N = number of accessions included in flow cytometry analysis. – 2x = diploid; 3x = triploid; 4x = tetraploid. Mean genome size with standard deviation data of individual plants follows Appendix S2.	Fig. 4. Boxplot representing range of genome sizes (in picograms) of species of Kaempferia subg.
