COMPARATIVE MORPHOLOGICAL ANALYSES OF THE GENUS Iris L., Pallidae

The qualitative morphological features of the Alpine-Dinaric and cultivated populations, as well as of the herbarium specimens of the genus Iris, series Pallidae, were investigated. The height of the plant, leaves, inflorescence, flowers (spathe, perigonium, androecium, gynoecium), fruits and seeds were analysed. It was established that the morphological features analysed did not show pheno-typic plasticity. The following qualitative morphological features have possible diagnostic signifi-cance: intensity of the leaf vein, spathe colour, perigonium colour, and pollen and seed morphol-ogy. Of no diagnostic use are ratio of filament and anther lengths (individual variability), and size and form of the fruits (intrapopulation variability)
