Contributions to the Atlas Florae Hungariae XIII.
85-88Views:57885The present paper is the 13th in a series of papers contributing new floristic data to complement the distribution maps of Atlas Florae Hungariae. We present altogether 1307 new occurrence data to advance our knowledge of the distribution of vascular plants in Hungary. New data are presented for 634 vascular plant species from 256 flora mapping quarter quadrates (CEU). Due to the unevenness of data collection, the data are highly dispersed over the area of Hungary. Most of the presented occurrence data are from the Great Hungarian Plain, the North Hungarian Mountains, and the Little Hungarian Plain regions. The enumeration includes rare native species (e.g., Androsace maxima, Erysimum crepidifolium, Orobanche gracilis, Peucedanum palustre, Pulsatilla zimmermannii, Scopolia carniolica, Vicia biennis), rare or data deficient adventive species (e.g., Euphorbia prostrata, Euphorbia serpens, Lindernia dubia), subspontaneous occurrences of native species (Asplenium scolopendrium, Daphne laureola, Chenopodium opulifolium), species spreading along linear infrastructure (Eleusine indica, Plantago coronopus, Sorghum halepense, Spergularia salina, Tragus racemosus), and also common native species with data deficient distribution maps (Agrostis stolonifera, Bromus benekenii, Bromus japonicus, Carex caryophyllea, Carex divulsa subsp. divulsa, Equisetum ramosissimum, Vulpia myuros).

Contributions to the Atlas Florae Hungariae XII.
77-84Views:422In this work, we report data supplementing the Distribution atlas of vascular plants of Hungary. Altogether 1325 data of 460 vascular plant taxa are reported as contributions to 149 quadrants in the Central European Flora Mapping grid system. The new stands of Phegopteris connectilis (NW foothills of the Vértes Hills), Sternbergia colchiciflora and Corydalis solida (Danube–Tisza Interfluve), Euphorbia angulata and Potentilla alba (Nyírség) are particularly noteworthy. In addition, new stands of numerous rare or scattered species are also listed: Allium paniculatum, A. sphaerocephalon, Asplenium adiantum-nigrum, Botrychium lunaria, Bulbocodium vernum, Clematis recta, Colchicum arenarium, Cyclamen purpurascens, Dianthus barbatus, Dictamnus albus, Doronicum hungaricum, Epipactis atrorubens, E. microphylla, E. tallosii, Equisetum hyemale, Hepatica nobilis, Hesperis sylvestris, Hordelymus europaeus, Iris aphylla subsp. hungarica, I. arenaria, I. sibirica, I. spuria, I. variegata, Jurinea mollis, Lilium martagon, Linaria biebersteinii, Linum flavum, Listera ovata, Lunaria rediviva, Lychnis coronaria, Melica altissima, Menyanthes trifoliata, Monotropa hypopithis, Muscari botryoides, Ophioglossum vulgatum, Orchis militaris, O. morio, O. purpurea, Ornithogalum brevistylum, Ornithogalum sphaerocarpum, Phlomis tuberosa, Primula veris, P. vulgaris, Pseudolysimachion incanum, Pulsatilla flavescens, Pyrola rotundifolia, Scilla vindobonensis, Scrophularia vernalis, Sedum urvillei subsp. hillebrandtii, Spiranthes spiralis, Stipa borysthenica, Stratiotes aloides, Thalictrum aquilegiifolium, Trollius europaeus, Veratrum album, Vinca herbacea, Vitis sylvestris, Wolffia arrhiza etc.

Contributions to the Atlas Florae Hungariae I.
101–115Views:189The 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.

A new alien species to the Hungarian flora: Polypogon viridis (Gouan) Breistr.
165–172Views:142Polypogon 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.

Distribution of Campylopus introflexus (Hedw.) Brid. in Hungary
212-219Views:62Based on field work data collected in 2013–2014, the authors generated a map of the current distribution of Campylopus introflexus for Hungary. Besides the coordinates and geographic name of the localities, an estimated size of the population, the type of habitat and substrate, the co-occurring moss species and affected vegetation types were also recorded. Altogether, 18 stands were found in 8 geographical regions of Hungary, in some cases Campylopus introflexus was found to be a new species record for the moss flora of the respective region (e.g. Dunántúli-dombság, Nyugatmagyarországi peremvidék). In addition to the pine plantations from where it was detected formerly, the mixed deciduous-coniferous forests, the acidophilous oak woodlands and man-made habitats were found to be also proper habitats for this moss taxon. Earlier data mainly originated from pine deadwood, the recently discovered stands were found on acidic soil surfaces. The most important cooccurring moss species were the followings: Hypnum cupressiforme, Polytrichum piliferum, P. formosum, Pohlia nutans and Ceratodon purpureus. Campylopus introflexus had prominently high coverage in the acidophilous oak forests of the Mecsek Mts, where it occurs on acidic sandstone covered with a thin debris of the bedrock. This neophyte moss is widely distributed in Hungary, and has stable populations. Further expansion is expected in the subatlantic and submountain regions of the country, and in regions characterised by acidic soils and pine plantations.

New occurrences of Ranunculus strigulosus in East Hungary
3–8Views:310The exact distribution of Ranunculus strigulosus Schur is poorly known in Hungary. Current occurrence data of the species mainly from Békés county and only one archive data from the Nyírség region, from the 1920s were known. This study presents eleven newly discovered occurrences in East Hungary. Populations were found in wet meadows, forest glades and poplar plantations. Nine of these populations are located at the southeastern edge of the Nyírség region and most of them are quite small. Three larger population were found in Nyírábrány, Álmosd and the Tócó Valley between Debrecen and Hajdúböszörmény. One of the newly discovered populations provides a new contribution to the flora of Bátorliget Marsh and Fen-wood NCA. Some morphological characters (hairs on the stem and the leaves, shape of the leaves developed before and after the mowing) are also discussed.

Continuing spread of Plantago coronopus along Hungarian roads
19–26Views:475In the course of our research of Hungarian transport routes, we observed an intensive spread of the Atlantic-Mediterranean Plantago coronopus L., a recently established species in Hungary. Between 2017 and 2019, it was detected in 47 flora mapping quadrats, which increased the total number of occurrences to 81 since 2013. Besides motorways, the main Hungarian transport routes were involved as well. 26 occurrences have been recorded along the roads 4/E60, E573, 8/E66, 86/E65 and 87, which are severely affected by international traffic. However, on routes avoiding international transit traffic, the species’ occurrences are still rare. In some cases, the predominant direction of traffic appeared to influence the formation of new stands. It is very likely that the first individuals that appeared along the section of the M86/E65 motorway between Szombathely and Hegyfalu in 2019, arrived primarily by northbound traffic, rather than along the road 86, which runs parallel to it only a few hundred meters away. Likewise, it seems certain that the spread of the species along the roads M1/E60, E75 (Mocsa, Tata, Páty) and M7/E71 (Fonyód, Balatonlelle, Kajászó) as well as the road 8/E66 (Bakonygyepes, Veszprém) is due to reproduction of older extensive local populations. At several localities along the outer bend of roundabouts or near the exits of motorways, a dispersal role of intense winter road salting was also observed. The largest populations were located mostly along ditches, next to the (often bare) lane of roadbeds that are heavily affected by mechanical and osmotic stress. The majority of stands were found within a 3 meters wide belt along the asphalt strip (5 meters was measured in the lawn of a cemetery once). Since the species is present continuously at several localities since 2013, it is considered as naturalised in Hungary, and its further spread can be confidently predicted. The current status of the species in Hungary is naturalised (non-trans¬former) neophyte.

Historical occurrence of Spergularia echinosperma, a rare Nanocyperion species in Hungary
3–9Views:264Three species of the genus Spergularia have been known from Hungary. The most widespread one, Spergularia rubra (L.) J. Presl et C. Presl occurs on young sandy fallow fields and other disturbed habitats. The other species, S. marina (L.) Bess. and S. media (L.) C. Presl, occur sporadically in saline grasslands, and both have been recently spreading along salted roads. During a revision of the genus Spergularia in Hungarian herbaria, specimens of the species S. echinosperma (Čelak.) Asch. et Graebn. were found. It is a rare species previously known to occur only in Czechia and Germany and to be extinct in Austria and Slovakia (a few occurrences along the Morava and Danube rivers between 1909 and 1953). However, it was recently discovered in Western Siberia and Kazakhstan. It is a typical mudflat plant that occurs on exposed sandy shores of water bodies. Two herbarium sheets collected by Gyula Tauscher from near the village of Ercsi (riverbank of the Danube) in 1903 were found in the Carpato-Pannonicum collection of the Hungarian Natural History Museum. In addition, a new specimen was found, collected in Slovakia (Danube near Šamorín, collected by Mihály Résely in 1868) at the vicinity of the Hungarian border. The species was not confirmed during a field inspection of the target localities in Hungary; therefore, we have to consider it extinct in the country as well as in the whole Pannonian Basin. Recently, S. echinosperma was split into two subspecies – subsp. echinosperma and subsp. albensis. The subsp. echinosperma is probably restricted to fishponds in the SW part of Czechia and subsp. albensis occurs mainly in the floodplains of the river Elbe in Germany. The extinct populations of S. echinosperma in the Pannonian Basin belonged to the subsp. albensis. This taxon is morphologically close to S. rubra but can be reliably distinguished by densely verrucose seeds and shorter than wide stipules.

Floristic data from the northern edge of the floristic region ‘Crisicum’ (NE Hungary) II.: Borsodi-ártér és Sajó–Hernád-sík
169–186Views:343In this paper we provide new floristic data for 126 species and one hybrid from the Borsod Plain and the Sajó–Hernád Interfluve (Borsod-Abaúj-Zemplén county, Northeast Hungary) observed between 2006 and 2019. A significant proportion of the data is related to gravel mining activities in the area. We present new localities for rare or sporadic native taxa in Hungary (e.g. Chenopodium murale, Ch. rubrum, Lycopsis arvensis, Chamaenerion dodonaei, Reseda luteola, Senecio viscosus, Gnaphalium luteoalbum, Cyperus glomeratus) as well as rare or sporadic adventive weeds (e.g. Lepidium densiflorum, L. virginicum). We publish additions to the distribution of several legally protected species (e.g. Pseudolysimachion longifolium, Nymphoides peltata, Epipactis tallosii, Leucanthemella serotina). Presence of some taxa is remarkable regarding to the flora of the whole area of Crisicum (Sherardia arvensis, Thymelaea passerina, Silene conica) or the Great Hungarian Plain (Monotropa hypopitys).

Spreading along the railways: morphology and invasion success of Vulpia ciliata in Hungary
145–156Views:422Vulpia ciliata Dumort, a widespread species in the Mediterranean region, has been introduced in several European countries in recent decades, mainly along railways. The species was first discovered in Hungary at Szolnok railway station in May 2016, then a few days later at Keleti railway station in Budapest. In 2020 the species was found in several Transdanubian railway stations. Apparently, V. ciliata has recently been established in numerous parts of the country, probably spreading by railway transport. Until now, the species has only been found in the vicinity of regularly used tracks (in a distance of 20 m at the most). Being an invasive alien species, V. ciliata can displace the native Vulpia myuros in ruderal vegetation along railway lines. The species can easily be distinguished from V. myuros by its hairy lemma. Moreover, it flowers earlier than the other two indigenous species in Hungary, often already in late April. Based on the characteristics examined (number of nodes in the upper 2 cm zone of the rachis, number of fruits per spikelet, rate of fertile and sterile florets within the spikelet, lower and upper glume length, lemma and awn length separately, rachis width in the upper 2 cm zone) we have concluded that V. bromoides and V. myuros are less different from each other than V. ciliata from these two species. In the case of V. ciliata subsp. ciliata, we observed that spikelets (detached from the inflorescens) function as dispersal units. Therefore we assume that the observed low fertility rate within the spikelets, as well as the presence of marginal cilia on lemmas promote the spreading success of V. ciliata (spreading in clusters, anemochory, zoochory, anthropochory). Its early maturation (in May) can also facilitate its spread along railways, because the populations survive the chemical weed control usually carried out in late spring. The other two Hungarian species usually ripen later (in June). For the time being, the spread of V. ciliata outside the Hungarian railway network may be hindered by climatic conditions, or by the lack of seasonal weed control outside that network, which otherwise offers a relative survival advantage for V. ciliata along railway tracks.

The occurrence of Viola collina Besser in the Bükk and Uppony Mts. (N Hungary)
254-258Views:116Herbarium revisions and recent field observations revealed the occurrence of Viola collina Besser in the Bükk and Uppony Mts. (northern Hungary). This species has not been reported from the North Hungarian Mountains thus far. Altogether 94 localities of V. collina have been recorded in that region between 2007 and 2014. A map of the species’ local distribution is provided. Local habitat preferences of V. collina are briefly discussed.

Taxonomic revision of alien Ludwigia species in Hungary
153–164Views:227Some tropical Ludwigia species have been planted as ornamentals in Hungarian thermal springs since the 1920s. Although they have become naturalised or even invasive in a few places, their specific identity remained generally uncertain. Our herbarium and field studies revealed that three species of alien water-primroses occur in Hungary. The most frequently planted one is Ludwigia repens, which is, however, a sporadic species in its native distribution area. We have found this species in several parts of the country. Although a few escaped and self-sustaining populations were also observed, this species has appeared to be non-invasive so far. Ludwigia grandiflora appeared in Hungary at the beginning of the 2000s. At the moment it is known from three localities, though spreading rapidly, becoming already invasive in its locality at Tata city. A similar species, L. peploides has recently been reported from two localities, where it forms small stands; the success of its naturalisation can be assessed in the future. We found no evidence for the Hungarian occurrence of L. alterniflora that had been published from Eger city. Therefore we suggest deleting this species from the current Hungarian checklist.

The subgenus Ceratochloa (DC. et P. Beauv.) Hack. (Bromus L., Poaceae) in Hungary
44-47Views:102The 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.

Cardamine occulta Hornem. in Hungary, and other stowaways of the ornamental plant trade
195–214Views:405During the study of the weed flora of garden centers in Hungary (among 2017–2020), remarkable populations of Cardamine occulta Hornem., a new alien for the Hungarian flora were found. C. occulta was present altogether in 51 of the 53 visited sites. Dominantly the regularly irrigated and continuously moist microhabitats (pots, containers, muddy surfaces of geotextile-covered beds etc.) were colonized. During the revision of our recently collected specimens, deposited in JPU and DE herbaria as Cardamine hirsuta L., further individuals proved to identical with this till overlooked species. One of them (27.08.2004., Heves county: Eger [8088.3; 8188.1], coll. by A. Schmotzer, deposited in DE collection) proved to the third documented occurrence in Europe, comparing to the accessed literature data. Eclipta prostrata (L.) L. and Urtica membranacea Poir. are also new aliens for the Hungarian flora. Several introduced individuals of these taxa were found in containers of imported thermophilous woody ornamentals at 4 and 2 sites, respectively. Tens of individuals of Eclipta prostrata were also found in a sapling-bed at another site. New populations of scarce or rare Euphorbia prostrata Aiton, E. serpens Kunth and Veronica peregrina L. were also documented.

Multiclavula mucida (Basidiomycota) and other cryptogamic taxa in the Hungarian flora
173–184Views:163The paper deals with the species found during cryptogamic flora mapping in 2023 that are remarkable from a floristic, taxonomic or conservational point of view. We present data from the Bükk Mts of two Trapeliopsis species which appear to be rare in Hungary. Multiclavula mucida, which is apparently a rare basidiomycete lichen species in Europe that prefers humid, montane habitats was discovered in the Mecsek Mts as a new species for the Hungarian flora. Of the knothole moss, Anacamptodon splachnoides, which is now thought to be entomophilic, we communicate the only extant population from Southern Transdanubia. We report the first occurrence of the atlantic-mediterranean Leptodon smithii from the Hungarian side of the Great Hungarian Plain. Numerous data of the corticole Neckera pennata indicate that in Hungary the distributional centre of this species is situated in the county of Baranya in the lowlands. New data from the Bükk Mts underline that in the Pannonian region Buxbaumia viridis is primarily a terricole species of acidophilous beech forests. We communicate the first occurrence from the lowlands of the alien lignicolous Sematophyllum adnatum which is dangerously spreading in Europe, at the same time one of the most vigorous populations in the Pannonian region. The third Hungarian occurrence of Callicladium haldanianum, a species that seems to spread in bogs, as well as the second occurrence of Racomitrium lanuginosum, growing abundantly on an andesite boulder scree in Mátra Mts, are also reported here. Of Phegopteris connectilis we present in photographic documentation the first extant population from Southern Transdanubia, and we discuss whether the first publication from Mecsek Mts is correct or exact. In addition to listing the floristic data, we also briefly discuss the (mis)use of distribution data in the context of climate change, the difficulties of distinguishing the microtaxa of some pteridophytes, e.g. Asplenium adiantum-nigrum agg. and Dryopteris affinis agg., and we correct one of our previously published, erroneous Hedwigia stellata data. Some interesting data of other taxa (such as Leucobryum glaucum, Palustriella commutata, Tetraphis pellucida, Gymnocarpium robertianum, Ophioglossum vulgatum) are also mentioned in the paper.

Floristic data from Miskolc and the Bükk Mountains (N Hungary)
267-274Views:86In the paper new floristic data originated form field works between 2009 and 2014 in the Bükk Mountains and in the city of Miskolc, Hungary are reported. Data presented here are mainly from the eastern part of the mountain range, near Miskolc, but there are also some data from the central and northern part of the mountains. The most interesting result is the discovery of a new stand of Epipactis tallosii in the inhabited area of Miskolc-Hejőcsaba, but in the inhabited area of Miskolc Cephalanthera damasonium, Neottia nidus-avis and Allium scorodoprasum was also found. New localities of Callitriche c.f. palustris, Alisma lanceolatum and Berula erecta are provided, which species have not been found in the Bükk recently, while Lactuca perennis, Crepis biennis and Lycopus europaeus was not known in the township of Miskolc so far. New localities of Iris pseudacorus, Iris sibirica, Clematis integrifolia, Carex acutiformis, Thalictrum lucidum, Pseudolysimachion longifolium etc. were found near MiskolcKomlóstető, Epipactis microphylla, Carex acuta, Eqiusetum telmateia, Listera ovata etc. were found near Miskolctapolca, and Epipactis tallosii, Juncus tenuis, Carduus nutans, Berula erecta, Scutellaria galericulata, Myosotis scorpioides and Ranunculus sceleratus were found in the vicinity of Miskolc-Görömböly. It can be concluded that the flora of the surroundings of Miskolc (i.e. Miskolc-Komlóstető, Miskolctapolca and Miskolc-Görömböly) are not yet known sufficiently.

Contributions to the Atlas Florae Hungariae XI.: Data from the Tokaj–Zemplén Mts and its surroundings
239–241Views:193This paper is the 11th in the series aiming to contribute data to the distribution maps published recently in Atlas Florae Hungariae. Our records were collected from the Tokaj-Zemplén Mts and the Bodrogköz region. The dataset includes 325 occurrence data of 75 vascular plant taxa from 53 flora mapping unit. Most of the represented taxa are legally protected, e.g. Aconitum variegatum, Alchemilla subcrenata, Aster amellus, Cardamine glanduligera, Centaurea triumfettii, Cephalanthera damasonium, Dianthus deltoides, Epipactis pontica, Gentianopsis ciliata, Orchis morio, Orthilia secunda, Petasites albus, Platanthera bifolia, Polygala major, Prunella grandiflora, Pulsatilla grandis, Rosa pendulina, Salix aurita, Scilla kladnii and Stipa dasyphylla.

Online distribution atlas of the Hungarian vascular flora (Atlas Florae Hungariae): Homepage structure and prospects of database building
238–252Views:398In December 2018 the online Distribution atlas of vascular plants of Hungary (Atlas Florae Hungariae) was published. The database was built from more than 1 million data records. It mainly contains data from the Hungarian Flora Mapping Programme, but herbarium and literature data were also processed. Maps of species richness illustrate the taxonomic diversity of biogeographical areas and shows the differences of survey quality. After the Flora Mapping Programme ended, between 2016 and 2019, additional data from scientific articles were processed. 25% of new data originated from the article series “Contributions to the Atlas Florae Hungariae” in the Kitaibelia journal, which significantly broadened the distribution of some species. Records of Mesophile forest species (e.g. Allium ursinum, Dryopteris dilatata) increased, as well as records of weed species (e.g. Euphorbia maculata, Senecio vernalis) which can be attributed to their natural spreading. The most important future tasks are to create a reviewed list of taxa and extend data records with an attribute table containing all additional information. Until now the database website is presented only in Hungarian (http://floraatlasz.uni-sopron.hu). Registration is available for anybody, after sending a request via e-mail (atlas.florae.hungariae@uni-sopron.hu). There are different options (excel file by e-mail or online web form) on how to upload floristic data for registered users. Data is only accepted if required information (name of taxa, date, data publisher, settlement, CEU code) is filled out. Each record of uploaded data is revised by the website administrator and taxa specialists. The English version of the webpage will be available in the near future.

Fern (Pteridopsida) flora of South Nyírség (East Hungary)
162–182Views:342The study presents a number of new data on the fern flora of South Nyírség, and reviews all available literature and herbarium fern records from the area. A total of 19 Pteridopsida species were detected in the region. The hart's tongue fern (Asplenium scolopendrium) and the soft shield fern (Polystichum setiferum) were hitherto unknown in the whole Nyírség region (flora district “Nyírségense”). The broad buckler-fern (Dryopteris dilatata), scaly male fern (Dryopteris affinis) and floating fern (Salvinia natans) are new records to the area of South Nyírség. Dryopteris dilatata has been found in a surprisingly great number of localities. Some morphological characters facilitating identification of this species are also discussed. The local pine plantations, fens, carrs and humid deciduous forests are important habitats for ferns. In some localities the co-occurrence of 5-6 fern species were observed. The increasing aridity in the last decade is posing a serious threat to ferns in the area.

Distribution and flora of areas with alkaline and saline soils in the Mezőföld, Hungary
39-61Views:191Areas with alkaline and saline (solonetz and solonchak) soils occupy substantial areas in the westernmost, Transdanubian part of the Great Hungarian Plain (Mezőföld). To this date, the flora and vegetation of only two localities have been studied in some detail, while the rest has remained largely unknown in this respect. In this paper, I provide brief descriptions of these little-known areas and present a list of halophytes with distribution data from the last 17 years. The names of the plants are followed by the name of the township and the geographical location where the plant was found, the code of the grid cell of the Central European Flora Survey grid that includes the location, and in selected species, the year when the species was first recorded. The list is arranged in alphabetical order irrespective of taxonomy. The occurrence data indicate that the floras of these saline-alkaline areas represent only subsets of, but in combination are almost identical to the overall flora of similar habitats in the Sárvíz plain.

Contributions to the Atlas Florae Hungariae IX.
253–256Views:266The current paper is the 9th in the series aiming to provide new data to the distribution maps of Atlas Florae Hungariae. Data of 734 vascular plant taxa (from 222 flora mapping quadrats) are presented in this study. The new localities are spread across nearly the entire country; however, most of the data are from the North Hungarian Mts, the northern part of the Danube-Tisza Interfluve, the southern edge of Hanság, alongside River Maros and the Hortobágy. Altogether, 1632 new data records are presented in this paper. The list mainly contains rare and locally important native species, as well as species with uncertain native/alien status (e.g. Allium ursinum, Chamaecytisus triflorus, Cotoneaster niger, Cyperus pannonicus, Elatine triandra, Eleocharis acicularis, Eleocharis ovata, Erodium hoefftianum, Geranium lucidum, Globularia punctata, Hippuris vulgaris, Hottonia palustris, Lindernia procumbens, Marrubium vulgare, Ononis pusilla, Orobanche bartlingii, Orobanche cernua, Pisum elatius, Polycnemum majus, Polygonum graminifolium, Ribes nigrum, Schoenoplectus triqueter, Verbascum ×denudatum, Verbascum ×vidavense, Viola canina subsp. schultzii). We report new localities of expanding alien species (e.g. Amaranthus deflexus, Artemisia annua, Euphorbia maculata, Helminthia echioides, Hordeum jubatum, Impatiens glandulifera, Ipomoea purpurea, Mahonia aquifolium, Panicum riparium, Robinia viscosa, Rudbeckia hirta, Veronica peregrina, Yucca filamentosa) and mention a few rare, successfully “surviving” alien plants with nature conservation value (e.g. Acorus calamus, Monochoria korsakowii). Moreover, occurrences of common plants are presented when new to the Atlas Floraea Hungariae (e.g. Bromus hordeaceus, Symphytum officinale, Vicia tetrasperma).
