Abstract

Comparative variability in some morphological properties, for example, in leaves and flowers, among and within each of three species Arum italicum Mill., Arum maculatum L. var. maculatum and var. immaculatum Reichb. as well as Arum alpinum Schott et Kotschy var. pannonicum Terpó and var. intermedium Terpó from three localities in Eastern Slavonia and from two in Baranya region in Croatia were studied. The investigation included the variability among and within of the populations and habitats and among the species. The results obtained indicated significant differences chiefly in some morphological parameters, such as in length of petiole and peduncle, in length of spathe, in length and diameter of spathe-tube, in length and diameter of appendix as well as in length of pistillate and staminate flowers. Moreover, the taxonomic treatment of the species Arum alpinum Schott et Kotschy as a disagreement was also discussed. The most of the morphological features are in the concordance with observations made by Prof. Bedalov.
