-The main aim of the present work is to contribute with new data to the distribution maps published recently in Atlas Florae Hungariae. Occurrence data of 297 vascular plant taxa from 247 flora mapping quarter quadrates (CEU) are presented. This floristic paper is somehow unusual because besides the occurrence data of rare or sporadic taxa (e.g. Armoracia macrocarpa (Waldst. et Kit.) Kit. ex Baumg., Samolus valerandi L., Epipactis voethii Robatsch), frequent, but more or less underrepresented taxa (e.g. Ranunculus ficaria L., Viola kitaibeliana Roem. et Schult., Gagea villosa (M. Bieb.) Duby), as well as alien taxa (e.g. Cymbalaria muralis G. Gaertn., B. Mey. et Scherb., Potentilla indica (Andrews) Focke, Tragus racemosus (L.) All.) are also enumerated, since our intention was to fill the -sometimes evident -gaps in the Atlas. The name initials of the author(s) who actually found the given occurrence are presented in brackets at each record.Keywords: distribution data, flora mapping, flora of Hungary, vascular flora Összefoglalás -Közleményünk célja a Magyarország edényes növényfajainak elterjedési atlasza térképeinek kiegészítése, főként aktuális előfordulási adatokkal. Összesen 297 edényes taxon előfordulási adatait közöljük az ország egész területéről, mintegy 247 flóratérképezési negyedkvadrátból. Az adatok között a ritkább taxonok (például Armoracia macrocarpa (Waldst. et Kit.) Kit. ex Baumg., Samolus valerandi L., Epipactis voethii Robatsch) mellett országosan elterjedt, de többé-kevésbé adathiányos fajok (például Ranunculus ficaria L., Viola kitaibeliana Roem. et Schult., Gagea villosa (M. Bieb.) Duby), illetve adventív fajok (például Cymbalaria muralis G. Gaertn., B. Mey. et Scherb., Potentilla indica (Andrews) Focke, Tragus racemosus (L.) All.) esetében is közöljük az atlasz térképeihez képest újnak bizonyuló lelőhelyeket.

Th e second part of the recently launched series includes miscellaneous new records from fungi to vascular plants. New chorological records of fi ve taxa of fungi are provided here: two new for Hungary (Entoloma tjallingiorum and Mycoacia nothofagi), one (Hohenbuehelia mastrucata) new for the Vértes and Börzsöny Mts, additional records and confi rmations for two taxa (Entoloma lampropus and Hohenbuehelia atrocoerulea) are also provided. New chorological records of three vascular plants are provided: one taxon (Draba muralis) new for the Tiszántúl region, two (Rubus armeniacus and Najas marina) new for the North Hungarian Mts.

Jelen dolgozatban 2006 és 2019 közötti időszakból, a Borsodi-ártér és a Sajó–Hernád-sík területéről gyűjtött florisztikai megfigyeléseinket tesszük közzé, összesen 126 fajról, és egy hibridről. Különös figyelmet fordítottunk a térségben jellemző kavicsbányákra, ezért az adataink egy jelentős része valamilyen módon összefüggésbe hozható a kavicsbányászati tevékenységek során létrejött élőhelyekkel. A dolgozatban bemutatjuk néhány országszerte ritka vagy szórványos őshonos faj (például Chenopodium murale, Ch. rubrum, Lycopsis arvensis, Chamaenerion dodonaei, Reseda luteola, Senecio viscosus, Gnaphalium luteoalbum, Cyperus glomeratus), ill. újjövevény (Lepidium densiflorum, L. virginicum) újabb előfordulásait. Védett, de nem feltétlenül ritka fajok lokális elterjedéséhez is kiegészítésekkel szolgálunk (például Pseudolysimachion longifolium, Nymphoides peltata, Epipactis tallosii, Leucanthemella serotina). Néhány faj előfordulását tiszántúli (Sherardia arvensis, Thymelaea passerina, Silene conica) vagy alföldi (Monotropa hypopitys) kitekintésben is jelentősnek tartjuk.

This paper reports the second Hungarian synanthropic occurrence of the rare Myricaria germanica. One flowering individual was found in a gravel pit near Hejőpapi (NE Hungary). The closest known population of the species is 60 km far from newly found locality. This occurrence indicates effectivness of anemochory. It seems, that abandoned gravel pits may be potential habitats of this threataned shub species.

Gypsophila perfoliata (Caryophyllaceae) is a rare, only casually occurring species in Central Europe. Its native range spans from western Asian to the coast of the Black Sea. Several adventive occurrences of G. perfoliata were documented in Central Europe, especially in Germany where the naturalisation of the taxon occurred during the first decades of the 20th century. As a rare weed, it is suspected to have been introduced with iron ore from the former Soviet Union via railways (Kryvyi Rih region, now Ukraine). In this paper, we gathered information on the occurrence of G. perfoliata from its adventive range. These data indicate an ongoing and fast spread of the species across Central and Eastern Europe. For instance, prior to this study, G. perfoliata have two occurrence records from Hungary. Six new and recent records from Miskolc town and its surrounding areas are presented in this paper. The studied plant occurs in former industrial areas (steel factory, transshipment yards, external slag heaps) or along transport lines (esp. road verges, railway lines). We also describe 18 phytosociological relevés taken at the location of occurrences. All occurrences were documented on heavily modified anthroposols, where the populations flourish on bare ground (esp. road verges or parking areas) or on ground with admixture of metalliferous slag debris. With the help of available orthophotos the presumed land-use history of the locations has also been reconstructed. Based on data presented here we recommend modifying the species’ adventive status in Hungary from casual to naturalised. Further expansion of the species is expected not only 172 at industrial sites but also at locations where slag material was utilised (e.g. landfill, road and rail construction). Due to its halophyte characteristics the species might expand its range along roads where de-icing salt is used.
