Abstract EN
Karyomorphological information is one of the most important characters for cytotaxonomy.
We described karyomorphology of 14 species of Parnassia in East Asia.
They had commonly the resting chromosomes of the simple chromocenter type and the mitotic prophase chromosomes of the proximal type.
The somatic chromosome number of 2n=14 was shown in three species, that of 2n=18 was shown in six species, that of 2n=18 or 36 was shown in two species, that of 2n=32 was shown in one species, that of 2n=36 or 36+1∼8 s was shown in one species, and that of 2n=18, 27, 36 or 45 was shown in one species.
They were commonly monomodal (gradual) decrease in length from the largest to the smallest chromosomes.
However, their absolute chromosome sizes were different from each other.
Average chromosome sizes were recognized as three types small (1.21 μm), medium (1.7–2.36 μm), and large (3.1–3.75 μm).
Parnassia palustris showed four cytotypes that could be likely cytogeographically correlated with habitats, polyploidy, and sizes of pollen grains.
