In this paper the method of creating indices for description leaf blade roundness and asymmetry, based on division of the leaf into 10 equal parts perpendicularly to the long axis was proposed. Along each division line the distance between the midrib and the leaf edge was measured separately for the left and right site of the blade. Sum of all 18 measurements, 9 on each side, may be treated as an index of the roundness of the leaf blade. Differences between sums of all measurements of the left and right leaf site could be a base for calculations of various asymmetry indices, including indicators of fluctuating asymmetry. Indices obtained by this method are quite sensitive and may be analysed using standard statistical methods.
