  Some small populations of Rostraria cristata and Cynosurus echinatus, two ‘old-new’ alien grass species in Hungary, were recently discovered in the city of Pécs (South Hungary). A morphological description of these species as well as a survey of their former and current localities are presented.

  Vital populations of Vulpia bromoides (L.) S. F. Gray and Luzula multiflora Kirsch. were found between Vajszló and Páprád villages (S Hungary) in 25 May 2022. The populations grew in a mesic forest clearing in the territory of “Bükkhát forest”. These species are new for the flora of the Drava Plain. The habitat is demonstrated by a phytosociological relevé.

  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.

  Polypogon viridis (Gouan) Bresitr., a new alien species to the Hungarian flora, was detected between the years 2016–2019. Water bent (P. viridis), originating from the Mediterranean basin, was recorded from several plant nurseries and outdoor flowerpots in Transdanubia, Hungary. The new Hungarian records fit into the observed phenomenon that ornamental plant trade is an important factor in the spread of this species. Morphological characterization and insertion of P. viridis into the Hungarian identification key are also provided in this paper. Since P. viridis was represented in large numbers at some of the Hungarian localities, future monitoring of its spread may be important to evaluate the invasiveness of the species in the country.

  The subgenus Ceratochloa is a taxonomically difficult small group of the genus Bromus. The species of this subgenus are mostly native to America, and are often introduced to other continents. Two species of them, namely B. catharticus and B. carinatus have been reported from Hungary so far. Bromus catharticus was first found in Győr city in the 1910s, much later (in the 2000s) in Környe and Kálmánháza villages. The Hungarian records of B. carinatus come from Keszthely and Sopron cities. We have recently found two new occurrences of B. catharticus in the city of Pécs, South Hungary.
