  We present six new occurrences of a rare non-native species, the sea lyme grass (Leymus arenarius (L.) Hochst.) in the Kiskunság region, Hungary. The populations grow in disturbed, secondary habitats (e.g., abandoned fields, recultivated landfills, surroundings of farms), but one of them begins to expand on the adjacent natural open sandy grassland. Most of the occurrences occupy several hundred square meters and in some cases it forms almost monodominant stands. We suppose that the species has the potential to become an invasive species in this inland sand region.

  Our study presents the actual status of potentially invasive Senecio inaequidens in Hungary. Literary and herbarium data are also discussed. We report some new data from ruderal places and near highways which are unmarked until now. The actualized distributional map of the species are given. We sign the potential habitat threats too.
