A new locality of Galeopsis angustifolia (Ehrh.) Hoffm. in Pyrzyce Plain (West Pomerania, Poland)

Abstract

The aim of the research was to explore a new locality of Galeopsis angustifolia (Lamiaceae), a rare taxa in Poland. The floristic composition of a plant community with G. angustifolia was determined. The species was recorded along the railway line from Pyrzyce to Stargard Szczeciński, near to the railway station in Okunica village, not used since 2004. Currently, the plant community with G. angustifolia occupies a transect >300 m in length. It is also sporadically found in the areas adjacent to the railway line. The species penetrates into ruderal communities from the Artemisietea vulgaris class and creates plant communities with Galeopsis angustifolia, a dominant species in the patches. Synanthropic species, e.g., Rubus caesius, Convolvulus arvensis, Senecio viscosus, meadow species, e.g., Arrhenatherum elatius, Potentilla reptans, Pastinaca sativa, and mosses of dry and rocky habitats also form plant communities with Galeopsis angustifolia.
