Taxonomic revision of roses (Rosa L.) of selected areas in buffer zone of the Low Tatras National Park (Slovakia)

The paper presents results of preliminary research carried out in 2011 in the area of two Protected Sites – CHA Jakub, CHA Kopec and Nature Reserve PR Mackov bok in the buffer zone of the Low Tatras National Park. Six native species and one native hybrid of roses were found there (1 from the Pimpinellifoliae section and 6 from the Caninae section) and their 13 varieties. The most numerous among them are Rosa canina var. dumalis Baker and R. × subcanina (H. Christ) R. Keller. Such great diversity of species and varieties insuch a small area (only 20.2 ha) proves considerable floristic richness, and occurrence of habitats preferred by roses.
