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. Keywords rare species; Galeopsis angustifolia; railway areas; plant communities IntroductionRailway lines create specific environmental and soil conditions for plant growth. Species growing in these biotopes have distinctive ecological features; they are tolerant to excessive light, temperature fluctuations, resistant to the strong effect of precipitation, frost, erosion, wind, and air movement initiated by passing trains [1]. Despite harmful abiotic factors, railway lines create a habitat for many plant species from different ecological groups. Wildlife developed along railway lines has been the object of interest of many naturalists for many years. A lot of attention has been dedicated to flora growing in railway areas [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21], including rare and protected plant species growing along railway embankments [22][23][24][25]. Galeopsis angustifolia from Lamiaceae is one of the rare species that grows in railway habitats in Poland [26,27].Galeopsis angustifolia (Ehrh.) Hoffm. is an annual plant with a height of 10-40 cm and a grey-hairy stem, without firm bristles near the nodes. It is characterized by lance-shaped or narrow lance-shaped leaves and by entire or softly corrugated leaf margins with 4 pairs of teeth at the most. The flowers are small (15-25 mm), with a red-violet perianth, gathered in pseudo-whorls. The calyx is very hairy, usually without glands, with visible veins in the lower parts and three times shorter than the corolla. The fruit is an ovoid nutlet which contains numerous seeds. It blooms from June till October [28,29]. According to the ecological indicator values, this species prefers warm regions and microhabitats (T = 5-4), and it grows in full light (L = 5). It is adapted to dry places (W = 2), rich in calcium carbonate (R = 5), poor in nutrients (Tr = 2) and organic matter (H = 2), scree and gravel [27].

“…Дослідник L. Rutkowski (1998) вважає його археофітом або кенофітом, тобто чужорідним, але тільки у північній частині країни, де рослини приурочені до антропогенних місцезростань. На думку E. Hultén і M. Fries (1986), тільки частина ареалу виду в межах Польщі може бути природною, з чим погоджуються Е. Szczęśniak (2010), M. Jonik et al (2010), W. Bacieczko, A. Borcz (2016). На території Словаччини G. angustifolia розглядається у складі природної фракції флори (Medvecká et al, 2012).…”
