The aim of this study was to characterise the flora and plant communities in the Moryńskie Hills, Poland. A total of 45 transects and 23 phytosociological relevés were established. Plant communities were identified based on the description of the test patch of the vegetation cover. The paper presents floristic analyses of vascular plants, which includes the taxonomic affiliation of species, their life forms according to Raunkiaer, and the species share in the geographical and historical groups. The results have been compiled and presented in tables and graphs, with a brief discussion. The non-forest communities occupy the largest area: xerothermic swards, meadows and pastures and to a lesser extent, scrub communities. Forests are represented by a riparian slope elm-ash wood Violo odoratae-Ulmetum minoris.
