Results are reported of morphological-anatomical investigations on cultivated varieties of <i>Lolium multiflorum</i>. These varieties exhibit wide differences as regards the width, thickness and length of leaf blades and thicknes of the dermal layer, mesophyll and diameter of vascular bundles. For a more precise characteristic of varieties the ratio of the derma layer thickness to the vascular bundles diameter and mesophyll thickness is important. In the characterization of varieties the correlations between morphological and anatomical traits of leaves can be utilized.
