  A new occurrence was found of the rare non-native species, Cycloloma atriplicifolia (Spreng.) J. M. Coult. in the Northern part of Kiskunság, Hungary on 02.07.2019 on a sandy road [N 47.297476°, E 19.382936°, KEF: 8782.1]. This is 80 km apart from the first and until now single occurrence of this species in Hungary. The authors removed the individuals, however, some seeds could remain in the soil. It is assumable, that the species was spread by wheels of the car used by the authors, as they visited the original occurrence of the species and the new one during the autumn in 2018 with the same car. This new occurrence draws attention to an important, but overlooked invasion pathway: to the invasion with cars of ecologists.

  Following global trends, the number of newly established alien plant species is increasing in Hungary. Not only professional scientists but also citizens could contribute to the discovery and documentation of new occurrences. One of the first records of the purple viper’s bugloss (Echium plantagineum L.) in Hungary originate from an online group dealing with wild plant species identification. This species is native in Western Mediterranean countries, and is introduced to other continents. In Australia, it is a well-spread, largely problematic invasive species, and it might show similar tendencies in Hungary as well. In order to acquaint the wider public with this species, we present its morphology, phenology and other characteristics and provide a possible inlay in the Hungarian identification key.

  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.
