In the alpine belt of the Julian Alps (Mts. Kukova Špica, Triglav, Pihavec, Razor, Jalovec, Mangart and Lopa) we conducted a phytosociological analysis of swards on ledges, ridges and rock faces with dominant Salix serpillifolia. These sites are typically relatively moist and the snow cover there is usually very persistent, despite their location on or just below ridges. In terms of species composition the studied community is transitional between snow-bed communities of the order Arabidetalia caeruleae and communities of windward ridges from the alliance Oxytropido-Elynion that we classify into the class Elyno-Seslerietea. Based on the analysis of proportions of diagnostic species we classify the studied community into the alliance Oxytropido-Elynion and into the new eastern-Alpine association Gentiano pumilae-Salicetum serpillifoliae. In the article we also provide a slightly modified phytosociological table of another alpine community in the Julian Alps, Crepido terglouensis-Potentilletum nitidae.
