and Cephalanthero-Fagion species. When determining the coenological character of Viola collina - considering the above - until clarification its classification into the CephalantheroFagion group also seems reasonable. Consequently the Viola collina can be considered a Bromo-Festucion pallentis, or a Cephalanthero-Fagion element in the Bakonyicum. This assumption is supported by previous data of BORBÁS (1890, 1900) from the BalatonUplands, Soó's records (1968) from the Sas-Hill (considered extinct) and some Slovakian data of BARTHA et. al. (1998). All described habitats of the protected Viola collina represent outstanding nature conservation value. The embodying associations belong to the most valuable elements of the vegetation of the Pannonicum; in some of their more natural stands certain endangered and highly endangered plant species find their only space for living. Taxa worth higlighting from the habitats of Viola collina mentioned in this paper are: Primula auricula subsp. hungarica, Carduus glaucus, Allium victorialis, Sorbus aria agg., Ranunculus nemorosus, Thalictrum minus subsp. pseudominus, Phyteuma orbiculare, Coronilla vaginalis, Amelanchier ovalis. Seseli leucospermum, Clematis recta, Polygala amara, Biscutella laevigata, Botrychium lunaria, Aconitum vulparia, Aquilegia vulgaris, Lilium martagon, Moehringia muscosa, Cotoneaster integerrimus, Platanthera bifolia. The above species make these - usually very small, fragmented - spots of habitats inestimable.
