Nowe stanowisko Senecio inaequidens (Asteraceae) w południowej Polsce

abstract: The paper presents new locality, habitat preferences and phytocoenological scale of South-African species Senecio inaequidens in the Kotlina Żywiecka basin. The population consists of about 200 flowering individuals on the anthropogenic sites – waste lands, railways and banks of dam reservoir. Plants grow in ruderal communities from the Artemisietea vulgaris class (Artemisio-Tanacetetum vulgaris, Echio-Melilotetum). The authors postulate that Senecio inaequidens is locally established (epoecophyte). Its propagules migrate by means of the railway transport.
