Abstract
The paper presents an analysis of mountain species occurrence in the Sopotnia Wielka creek, in the Beskid Żywiecki Mts (Western Carpathians, Poland). The list contains 55 plant species, which represent the whole altitudinal spectrum from piedmont to alpine zones (Viola biflora, Mutellina purpurea). The species inhabit mostly moist and wet communities along creek. They represent mainly the Alpic-Central-European distributional type. Three species are endemics for the Carpathians: Aconitum firmum subsp. firmum, Crocus scepusiensis, Dentaria glandulosa.
