The paper presents morphological diversity within Rosa dumalis Bechst., species identified among others in the buffer zone and the area of the Low Tatras National Park (Slovakia). This taxon belongs to the polymorphic section Caninae DC. em. Christ., and its morphological differentiation particularly relates to the degree of hairiness and glandularity leaves and the presence or absence glandules on pedicels. Based on these features nine varieties of this species were distinguished in Europe by Popek (1996). Four of these varieties, R. dumalis Bechst. var. afzeliana (Fr.) Boulenger, R. dumalis Bechst. var. dumalis, R. dumalis Bechst. var. caesia (Sm.) Boulenger and R. dumalis Bechst. var. coriifolia (Fr.) Boulenger, were found in the analyzed area.
