The occurrence of 10 lower taxa within species Pyrus pyraster L. (Burgsd.) was confirmed in Slovakia. Among 507 of the evaluated plants on 64 localities, there were recorded 2 sub-species of the wild pear – Pyrus pyraster subsp. pyraster and Pyrus pyraster subsp. achras . Subspecies pyraster was represented by 4 varieties (pyraster, elongata, pénzesiana, brachypoda ) and 5 forms (populifolia, cordifolia, rhomboidea, ovata, slovenica ). All lower taxa were visually classified according to the leaf and fruit characteristics. Numerical classification based on discriminant analysis according to quantitative traits was done. Some discrepancies were found up to 16.7% between visual and numerical classification on particular levels of the lower taxa identification.
