Sažetak
Patzkea paniculata (L.) G. H. Loos (=Festuca paniculata (L.) Schinz et Thellung) forms very localized mondominat grasslands in the subalpine belt of the Northern Velebit Mt (Croatia). Ecologically, these grasslands have intermediate position between relatively dry calcareous grasslands belonging to ass. Festucetum bosniacae Horvat 1930 and acidophilous grasslands of ass. Nardetum strictae Horvat 1930. The whole grassland complex was studied based on vegetation relevés, floristic diversity and ecology. It was shown that the distribution of these communities is determined by factors of topography, geomorphology and pedology, where P. paniculata grasslands are developed mostly on SW exposed slopes, with inclination of 11- 26°, and in the altitudinal belt from 1250-1320 m a.s., on leached soil which completely cover the limestone bedrock. Additionally, their relations to grasslands dominated by P. paniculata of other Balkan mountains, the Alps and the Apennines were studied. Together with grassland communities of NW Balkans they are more closely related to Alpine ones than to the central and Southern Balkan ones, which, on the other hand, are more similar to Apennine communities. Grasslands from the Velebit Mt share a small set of common species with the nearest known F. paniculata grasslands from the Mts Cincar and Vranica (Bosnia and Herzegovina) e.g. Festuca bosniaca, Euphorbia carniolica, Knautia dinarica, Scorzonera purpurea subsp. rosea, which are all Illyrian species reflecting phytogeographical position of these communities. With grasslands from the mountains of other Balkan phytogeographical provinces – Mesic (Suva planina, Vlasina and Besna kobila) and Scardo-Pindic (Bistra) it shares only very small proportion of common species, which have wide area of distribution (e.g. Leucanthemum adustum, Stachys officinalis s.l., Allium carinatum, Chamaespartium sagittale, Carex caryophyllea). Floristic connection with the Apennines is very weak with Campanula glomerata and Carlina acaulis subsp. caulescens as common species. However, connection with the Alps represented in ca. ten common species, is much more prominent. Some of common species are Anthyllis vulneraria s.l., Brachypodium pinnatum, Hieracium hoppeanum, Potentilla erecta, Centaurea triumfetti, Scabiosa lucida, Veratrum album and Senecio doronicum. Such phytogeographical connections of described grassland community reflect its position on NW border of Illyrian province, which can be considered as bridge between the Alpine F. paniculata grasslands with those on the Balkan mountains.
