FIGURE 3. Principal coordinate analysis (PCoA) of 13 populations of Odontarrhena tortuosa based on 27 morphological characters and population means. The first three components explain 46.3%, 18.5% and 10.1% of the variation, respectively. Different colours and symbols are used to mark the two ploidy levels, two subspecies and populations from three regions differing in the type of substrate: diploids of O. tortuosa subsp. heterophylla from rocks of the Slovak Karst and Vihorlat Mts in eastern Slovakia (black squares), diploids of O. tortuosa subsp. tortuosa from habitats with sandy and rocky screes in the Gerecse, Pilis and Buda Mts in the northern part of central Hungary (black circles), and tetraploids of O. tortuosa subsp. tortuosa from sand dunes in southwestern Slovakia, central Hungary and northern Serbia (white circles).
