NEW STAGE OF THE INVASION: SPOROBOLUS VAGINIFLORUS (POACEAE) REACHED HUNGARY

Sporobolus vaginifl orus, a “for a long time expected” invasive alien of North American origin has now reached Hungary. Th e fi rst stands were recorded in 2015 in SW Hungary on the motorway M70 near Letenye; its occurrence was already foreseen in view of its expansion along the roads of Croatia and Slovenia. Similarly to other aliens (e.g. Senecio inaequidens, Plantago coronopus) arriving from the Adriatic direction on the newly constructed motorways the authors reckon with its further rapid expansion in Hungary

Novelties in the vascular flora of Croatia

We report on and discuss records of five species new to the vascular flora of Croatia. Calamagrostis canescens was found near Đurđevac in remnants of fen vegetation, and we consider it a critically endangered species in the flora of Croatia. Agrimonia procera is native or archaeophyte in central Croatia and its discovery is in accordance with its earlier use as a medicinal plant. Amaranthus emarginatus is an exotic newcomer that was previously found in urban habitats on the north Adriatic coast. Carex vulpinoidea and Oenothera suaveolens were shown to be locally established species, in meadows along the Kupa River, and on the bars of the Drava River, respectively. In addition, we present new distributional and ecological data on two neophytes (Cardamine occulta, Humulus scandens) that were only briefly mentioned in earlier sources from Croatia

Tri nove strane vrste u flori Hrvatske

During field research in 2022 in the area of Kvarner and Istria, the spontaneous appearance of three non-native species (Catalpa ovata, Oenothera lindheimeri, Salvia hispanica) outside the area of primary cultivation was observed. These species are ornamental plants, food plants or part of the park dendroflora. It seems that these species appear as casual, but monitoring in the next years will show whether their naturalization will be successful.Tijekom terenskih istraživanja na području Kvarnera i Istre uočena je spontana pojava tri strane vrste izvan područja primarnog uzgoja i upotrebe (Catalpa ovata, Oenothera lindheimeri, Salvia hispanica). Ove su vrste izvorno ukrasne biljke, dio su parkovne dendroflore ili se koriste kao hrana. Čini se da je njihova nazočnost na prirodnim staništima povremena, ali će praćenje ovih vrsta u narednom periodu pokazati hoće li njihova naturalizacija biti uspješna
