Karyological analyses of the Alpine-Dinaric populations of the Genus Iris L., Pallidae series (A. Kern.) Trinajstić (Iridaceae)

The karyology of somatic chromosomes of the Alpine-Dinaric and cultivated populations of the genus Iris, Pallidae series (species I. cengialti, I. illyrica 1. pseudopallida and cultivated species I. pallida) was analysed. For all the populations analysed, except the population of Stara Baśka, the mitotic number of chromosomes 2n=24 has been established. In the population of Stara Baśka, in two plants, the mitotic number of chromosomes 2n=22 was found. Karyotypes of all species, except the clones of cultivated I. pallida specimens, showed an inter-population variability. Chromosome morphology similarities between some populations of the Pallidae series indicates their common origin and relatively great number of symmetrical chromosomes suggest that the speciation process within the series is not complete. The existence of genomorphological plasticity justified the possibility of the appearance of hybrids within series (perhaps population of Stara Baśka).
