Diagrams showing the result of flow cytometric determination of DNA ploidy levels of selected specimens. A tetraploid sample belonging to the Lepisorus clathratus complex was used as the internal standard (IS, grey graph). X-axis shows the relative fluorescence, Y-axis the number of nuclei. (A) Platygyria specimen 28 with cpDNA belonging to Nyingchi Platygyria (blue graph). (B) Platygyria specimen 101with cpDNA belonging to G3 (green graph), (C) Platygyria specimen 38 with cpDNA belonging to G4 (red graph). (D) Platygyria specimen 119 with cpDNA belonging to G5 (brown graph). Dashed lines indicate the divide of the genome size interpretation: 4x, <4x, and >4x based on the IS = 4x.
