Data to the flora of Heves–Borsod Plain I. Distribution of forest, forest steppe and steppe elements
16-65Views:228This paper reports new floristic data of 159 taxa (158 species and one hybrid) from the Heves–Borsod Plain (5 micro-regions between the Mátra and Bükk Mountains and the Tisza River valley). The data were collected between 1999 and 2018 and supplemented with collected specimen (altogether 93 herbarium sheets). This study is the first part of a thematic series that analyzes the distribution patterns of forest, forest steppe and dry grassland ‘steppe’ species, beyond reporting floristic data. The data were derived from 51 flora-mapping quadrats (CEU), based on 5.395 field collected data records. Some indicator species of the three species groups have been assessed in detail (with the addition of distribution maps of 25 species). I have also tested two East-West direction ‘lines’ (the 100-meter isoline and the Csörsz Ditch) for the possible existence of North-South chorological gradients in the area. True forest species (mostly Querco-Fagetea elements) show a dispersed pattern, their representatives can be linked to forest blocks appearing in the landscape. Streams from the adjacented hilly areas (even if they are strongly modified) are very important in the dispersal of the forest species. Their significance and role are decreasing towards the South. For some steppe and forest steppe species (e.g. Brachypodium pinnatum, Campanula bononiensis, Clematis recta, Elymus hispidus, Lychnis viscaria, Ranunculus illyricus, Sanguisorba minor, Stipa spp., Teucrium chamaedrys, Trifolium alpestre, Vinca herbacea) the examined lines indicate a regional area boundary, while for other species (e.g. Phlomis tuberosa, Thalictrum minus) gradient-like distribution differences were not observed. In the distribution of many species an additional southern gradient running along the northern boundary of the former Heves Floodplain was detected. Southwards to this line, the representatives of the selected species are already very sporadic, occurring only in synantropic habitats (e.g. Vincetoxicum hirundinaria).

Ceratocephala testiculata (Crantz) Roth and further data to the flora of the foothills of Bükk Mts.('Bükkalja', NE Hungary)
81-142Views:238This paper reports new floristic data of 367 taxa (365 species and two hybrids) from the foothill region of Bükk Mts. ('Bükkalja', NE-Hungary) based on 5470 field collected data records. The data was collected between 1997–2014 and supplemented with herbaria (altogether 344 herbaria sheets). Data evaluation was based on the comprehensive Bükk Flora of András Vojtkó and further papers. Altogether 45 species were registered as previously unreported from the area, whereas three species had old data (Acer negundo, Elaeagnus angustifolia, Xanthium strumarium). Out of the newly registered species six native species inhabits natural habitats (Carex flacca, Ceratocephala testiculata, Glycerrhiza echinata, Gypsophila paniculata, Kochia laniflora, Marrubium vulgare), whereas five species represents the weed flora (Anthemis ruthenica, Chenopodium ficifolium, Eragrostis pilosa, Senecio vernalis, Xanthium strumarium). The majority of the newly observed species are adventives. Five species were also regarded as recent introduction regionally, although they are native in the country (mostly lowland species: Crypsis alopecuroides, Limonium gmelini subsp. hungaricum, Salsola kali, Scirpoides holoschoenus, Trifolium angulatum). Typical threats observed are landscape and habitat degradation by invasive alien species out of which 11 are newly added. Mass occurrences were detected for the following invasive alien species: Bidens frondosa, Impatiens glandulifera, Phytolacca esculenta, Xanthium italicum. 43 species are also registered, which did not have recently published data from the area. These species include more native elements representing different habitat preferences (dry grasslands, wet meadows, forest and weeds). In case of 65 species the unravelled new occurrences increased significantly, thus contributed to the clarification of their distribution pattern. It was found that the floristic data accumulated on a decade-scale are not sufficient for the analysis of floristic trends, but could serve as a good basis for surveying floristic gradients between the mountainous and lowland areas.

Flowering phenology and distribution pattern of Lizard Orchids (Himantoglossum)
157-167Views:121Hybridization is very rare between the species of Himatoglossum genus, despite the fact that it is common in other orchid genera. The reasons for this can be the lack of overlapping distribution areas or the different flowering period of the species. In the paper distribution and flowering data of Himantoglossum species are presented from herbarium sheets or references (sources paper-based or internet). We collected 1001 precisely dated flowering records of 12 species. In case of 6 species (H. adriaticum, H. caprinum, H. comperianum, H. hircinum, H. jankae, H. robertianum) we had sufficient records to calculate the average flowering day and blooming length. According to the collected data the distribution of the species are overlapping except for H. formosum, H. galilaeum and H. metlesicsianum. Studying 55 species pairs, insignificant differences in blooming time were only at 21 species pairs, among them only 5 (H. comperianum - H. caprinum, H. montis-tauri - H. comperianum, H. hircinum - H. adriaticum, H. montis-tauri - H. caprinum és H. jankae - H. calcaratum) have overlapping distribution area. Data on hybridization could be found only at three species pairs among them. From the results we can conclude that in the case of Himantoglossum genus the rarity of hybridization is mostly due to the phenological isolation.

The Sea milkwort (Glaux maritima) in the Carpathian Basin
10-20Views:336Sea milkwort (Glaux maritima L.) is a broadly distributed species in the northern hemisphere, inhabiting primarily maritime habitats from the arctic to the temperate zones. It is also found inland in semi-arid and arid regions with saline soils. Its status in the Carpathian Basin has become very uncertain owing to the lack of known extant populations. To evaluate its current status, I review all known occurrences within the Carpathian Basin where this species has been recorded or collected, and report five new localities of the species in Hungary, all in the western part of the Great Hungarian Plain. I also analyze habitat relationships of the species using traditional phytosociological relevés. Review of species distribution data in the Carpathian Basin revealed that sea milkwort has undergone severe reduction in population number and disappeared from many localities. Currently, only a few populations can be found in this region: the Northern Carpathians in Slovakia and the western part of the Great Plain in Hungary. In Transylvania (Romania), only a single population has been reported recently suggesting the critical status of the species there. Features of the habitats confirm the halophytic nature of the species and its fidelity to wet saline meadows. Its common accompanying species are mostly broadly distributed, salt-tolerant plants. Heterogeneity of the samples in species composition suggests that sea milkwort is not a habitat-specialist species. Several of its common associates in Hungary are also found in sea milkwort habitats in Mongolia, Asia and Utah, North America. Based on the available evidence, sea milkwort shall be considered a severely threatened plant in the Carpathian Basin. Characteristics of the vegetation in its habitats do not explain its occurrence in mountainous environments.

Contributions to the Atlas Florae Hungariae XIII.
85-88Views:58007The 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).

Data to the flora and geobotany of Kisalföld (Lesser Plain) region, NW Hungary
235-253Views:145Lesser Plain (Kisalföld) – divided among three countries (Austria, Hungary and Slovakia) – is the westernmost part of the lowland areas of the Pannonian Basin. Present paper provides a résumé of the authors’ floristic work from the Hungarian part of the area, describing localities, habitats and regional phytogeography of 57 taxa altogether. The localities were listed according to the classification of small geographic regions. The most important results of the study are as follows:
- We recorded 5 species new to the region (Brachypodium rupestre, Bromus ramosus, Hypericum dubium, Lathyrus sphaericus, Tordylium maximum); all of them can be considered as submontane-montane elements.
- We reported several species new to a microregion within the Lesser Plain: montane species in the W-SW part of the Plain (Cirsium rivulare, Dryopteris dilatata, Equisetum telmateia), loess-connected species mainly on the Moson Plateau (Agropyron cristatum, Allium atroviolaceum, Euphorbia salicifolia, Viola ambigua); and occurrences of species on sandy soils near the Lake Fertő (Draba nemorosa, Stipa pennata).
- We explained the known localities of several salt tolerant species (e.g. Carex divisa, Crypsis alopecuroides, Juncus maritimus, Limonium gmelinii, Suaeda pannonica) from the Lake Fertő and its surroundings.
- We assessed the role of the forest management and nature conservational actions in the distribution of some important tree species (Acer tataricum, Betula pubescens, Fraxinus ornus, Quercus petraea, Salix pentandra).
- We discussed the regional nature conservational status of several protected and/or threatened species (e.g. Allium carinatum, Allium suaveolens, Carex strigosa, Hottonia palustris, Potamogeton coloratus, Stellaria palustris) in the Lesser Plain.
The activities of the authors in the surroundings of Győr were supported by monitoring results gained during the Hungarian Little Plain project (LIFE08 NAT/H/000289).

Taxonomic revision of alien Ludwigia species in Hungary
153–164Views:298Some 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.

Data on the distribution of some protected plant species and on their presence in secondary habitats
183-199Views:1828In this paper, I publish my floristic data on some protected and strictly protected plant species collected in Hungary between 2016 and 2021. The data published in this paper cover 31 micro regions of Hungary, but most of them come from the Great Hungarian Plain, especially from Pest and Bács-Kiskun counties. I describe the occurrences of 41 protected and three strictly protected vascular plant species (two ferns and 42 flowering plants), some of which represent new data for the particular micro region or even larger geographical areas (e.g. Botrychium matricariifolium, Thlaspi alliaceum and Nasturtium officinale). For some species, the published data either come from floristically understudied areas (e.g. Ranunculus illyricus, Vinca herbacea and Cardamine amara) or are considered rare in the certain region and/or in the whole country (e.g. Apium repens, Cnidium dubium and Vicia narbonensis). For other species, the newly reported occurrences are presented as complement to the already known distribution data (e.g. Cephalanthera damasonium, C. rubra, Linaria biebersteinii, Sonchus palustris and Agrostemma githago). In support of the nature conservation actions, I provide data from the flora of some floristically understudied micro regions (e.g. Dorozsma-Majsai Sand Ridge, Bácskai Loess Plain) and try to highlight the role of canals in Hungary in species and biodiversity conservation, by the example of the Danube-Tisza canal. In this manuscript, I publish data on twelve protected plant species from the Danube-Tisza canal and its canal bank (eg. Peucedanum palustre, Carex paniculata, Clematis integrifolia).

Data to the flora of Southern-Nyírség and its surroundings
68–85Views:1728In this paper we provide data on the flora of Monostorpályi, a floristically underrepresented settlement in South-Nyírség and Berettyó–Kálló interfluve, and publish some interesting floristic observations from the Debrecen city area. In our compilation we provide data on 58 plant species. Among the species listed in the enumeration we find taxa from the region not previously reported at all (Lathyrus nissolia, Gagea villosa, Catabrosa aquatica, Potamogeton lucens, P. pusillus). In total, we publish new occurrence data for 16 protected plant species, which are generally typical of the natural habitats of the Nyírség, but are on the decline overall (e.g. Hottonia palustris, Dianthus superbus, Cirsium rivulare, Lychnis coronaria). We also provide data on the distribution of some rare or declining weed species (Anthemis cotula, Myagrum perfoliatum, Agrostemma githago) and confirm the previously known occurrence of some poorly known plant species (Luzula pallidula, Carex hordeistichos). Furthermore, the spread of some alien species (Broussonetia papyrifera, Phyllostachys sp.) is also highlighted.

Results of floristic and phytogeographical research in the Velence Hills (Hungary, Transdanubian Mts)
117–152Views:436A recent floristic mapping of the Velence Hills has clarified the local distribution of many plant species. This study presents records of 219 phytogeographically significant or sporadic/rare taxa (216 species/subspecies and 3 natural hybrids). The local distribution of some species representing typical regional distribution patterns (Alyssum turkestanicum, Artemisia austriaca, Bupleurum pachnospermum, Doronicum hungaricum, Hypericum elegans, Lathyrus sphaericus, Minuartia viscosa, Ornithogalum comosum, Scabiosa canescens, Sedum caespitosum, Sternbergia colchiciflora, Vinca herbacea) are shown on maps. More than fifty taxa previously unknown from the area were recorded during the floristic mapping, including phytogeographically significant ones, such as Bassia laniflora, Brassica elongata, Bupleurum praealtum, Centunculus minimus, Hypericum elegans, Orlaya grandiflora, Phleum bertolonii, Silene dichotoma, Stipa tirsa, Tordylium maximum, Trifolium diffusum, T. ochroleucon and Valeriana dioica. In terms of phytogeography, the Velence Hills can primarily be characterised by the co-existence of continental and sub-Mediterranean elements as well as species of acidophil and strongly basic habitats.

Online distribution atlas of the Hungarian vascular flora (Atlas Florae Hungariae): Homepage structure and prospects of database building
238–252Views:514In 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.

Data to the distribution and nature conservation of Sorbus bakonyensis
229-233Views:1330Sorbus bakonyensis (Jáv.) Jáv. (syn. S. majeri Barabits) is an apomictic species with a very narrow distribution range in the Bakony Mts (Hungary). Its previous occurrence data were published only from Kopasz Mt. (~Kápolna Hill, Csordás valley) above the village Márkó. It was possible to slightly expand the known area of the species to the East and to the West (Kis-Bükk Mt) of Kopasz Mt. with a detailed mapping. Due to the number of known individuals (six mature trees and a variable number of seedlings) and its small distribution range (~2 km2) the species is critically endangered. Regarding its small population, the high number of big game (wild boar, red deer) and the more and more frequent drought periods are significant risk factors. In situ preservation of the species is still a realistic goal, but ex situ propagation in tree nurseries and reintroduction to the suitable habitats of the mapped area (clearings, forest edges) are also justified.

Contributions to the Atlas Florae Hungariae X.
101–106Views:392This paper is the 10th in the series aiming to contribute with new distribution data to the maps published recently in Atlas Florae Hungariae. Distribution data of 686 plant species from 194 flora mapping units are published in this study, but all of them are listed in an electronic appendix. As a result of local surveys, more than 100 new species were found in a single flora mapping unit. Other “linear surveys” along the National Blue Trail revealed 142 new species in 10 flora mapping units in total. Among these, Carex strigosa is one of the most interesting taxa in the Bakony Mts. Previously published and new distribution data of this legally protected sedge species suggests that it is spreading from SW to NE within the Transdanubian Mts. Results from our survey shows that studying synanthropic habitats like frequently used hiking trails might provide a significant amount of new data points at the scale of Hungarian Flora mapping units. Moreover, similar studies might shed some light on the origins and migration routes (e.g. Illyrian and Dacian routes) of “native” species.

Leucojum vernum at the Súri-Bakonyalja and overview of its distribution in the Bakony Region
242-246Views:388In Hungary Leucojum vernum is considered a plant species of montane character, distributed predominantly in Transdanubia. Apart from some isolated localities (Zalaszántó Basin Mts, Tapolca Basin), the occurrences of the species are mainly confined to the region “Magas Bakony” and its periphery within the Hungarian Middle Mts. In the spring of 2020 a large population was discovered by the author in the region “Súri-Bakonyalja”, which significantly expands the known local distribution range of the species. The new population, together with other phytogeographically significant species (e.g. Anemone nemorosa, Corydalis intermedia, Veratrum album), was found in a poorly explored valley system (Kisbér village: Báró-erdő). Based on all literature and herbarium records, the local distribution range of L. vernum is surveyed.

Contributions to knowledge on the distribution of nine adventive or invasive algae species in Hungary
11-21Views:128Hungarian records of nine adventive or invasive algae [Didymosphenia geminata, Nitzschia closterium, Reimeria sinuata, Navicula schroeteri, Pleurosira laevis (Bacillariophyceae); Pediastrum simplex (Chlorophyceae), Cylindrospermopsis raciborskii, Cuspidothrix issatschenkoi, Sphaerospermopsis aphanizomenoides (Cyanobacteria)] are presented. Navicula schroeteri Meister is a new species for the Hungarian flora. Although the observed distribution patterns of these species were very different, the increasing frequency of their appearance indicates significant effect of climate change on abiotic environment of inland waters, such as the increase in water temperature, increase in salt concentration, and eutrophication. The significance of continuous biomonitoring is emphasized, which, through the recognition of natural and human-induced changes in species composition of algae, or the appearance and rapid expansion of non-indigenous species, can detect environmental changes of inland waters.

Contributions to the flora of Western-Transdanubia (W Hungary)
213-234Views:146In this paper, we presented the results of our floristic survey in West-Hungarian region. The data were collected between 2005 and 2015 and supportted with herbaria or photo-documentation. This paper reports new floristic data of 98 taxa from West-Hungary with altogether 172 field-collected data records. In the survey we focused on little-known taxa with a phyto-geographic importance. For some taxa we checked the herbarium specimens of Savaria Museum and Natural History Museum of Budapest. During our fieldwork we recorded 8 species new to W-Hungary, including 3 species considered to be native to the region [Oenanthe banatica Heuff., Koeleria pyramidata (Lam.) P. Beauv., Polycnemum majus A. Braun.]. Almost all of the recorded species are regarded as indigenous plants, many of them has nature conservation importance, thus, their monitoring are highly advised. We found new localities of many species which of high importance for plant geography describing their current distribution. Most of the recorded species occur in natural or semi-natural habitats, but some taxa were found in synanthropic habitats and extensive arable lands.

The microscopic fungi of protected plant species in the Őrség National Park and the surrounding area (W Hungary)
187-211Views:67The paper deals with the study of microscopic fungi occurring on protected plant species of the National Park of Őrség and the surroundings. The survey includes both field observations and laboratory tests. The aim of the study was to identify the microscopic pathogen fungi living on protected plant species. Also spatial and temporal distribution, infection and damage rate of pathogenic fungi infections were determined for some protected plant species. Between 2002 and 2009 mycological research was conducted including 78 protected plant species and near to one hundred fungus species were identified on them. We provided data at the first time of microscopic fungi found on protected plants of Őrség.

Multiclavula mucida (Basidiomycota) and other cryptogamic taxa in the Hungarian flora
173–184Views:324The 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.

Contributions to the Atlas Florae Hungariae V.
383–403Views:203The current paper is the 5th one in the series aiming to contribute with new distribution data to the distribution maps published recently in Atlas Florae Hungariae. Several distribution data of 360 plant taxa from 66 flora mapping units are published in this study. Most of them are from the South Transdanubia. As a result of systematic surveys, more than 30 new species were found in 6 flora mapping quadrates. Most of the species are frequent, treated usually as weeds, but some of them are rare (e.g. Anchusa azurea, Centunculus minimus, Euphorbia stricta, Hypericum humifusum, Sagina apetala), and in some cases they are legally protected species in Hungary (e.g. Asplenium adiantum-nigrum, Dryopteris affinis, Festuca dalmatica, Gymnocarpium dryopteris, Urtica kioviensis).

Research on the distribution of woolly cup grass (Eriochloa villosa) in the northern part of Borsod-Abaúj-Zemplén county, Hungary
27–32Views:503Eriochloa villosa (Thunb.) Kunth was recorded for the first time in Hungary in 2007. Since then, the species spread intensively in the area and appeared at some other parts of Hungary. We carried out a research at the current distribution range of the species in the northern part of Borsod-Abaúj-Zemplén county. We asked how big is the infested area surrounding the place of the first occurrence and whether other occurrences could be found in other parts of the investigated area. This article also gives a review on its known localities in Hungary and neighbouring areas. During the field research, 58 locations of the species were identified, it occurred mainly in ploughed and unploughed agricultural fields, and at some places in disturbed grasslands, too. It has spread on a large scale around the neighbouring areas of the first location found in 2007. Other locations were also found even at more distant places such as in the valley of the Sajó and Bódva rivers and in the Cserehát region. This means that further spread of Eriochloa villosa can be expected, especially in areas with an intensive agricultural activity, in disturbed grasslands, and a threat of its appearance is also suspected in open natural habitats.

Contributions to the flora of the Szuha watershed and adjacent territories (NE Hungary)
27-67Views:320This paper presents new floristic data of 415 taxa from the Putnok Hills and Sajó Valley microregions (Northern Hungary). Records were collected between 1991 and 2021. In the first part new occurrences of legally protected (e.g., Cypripedium calceolus, Iris aphylla subsp. hungarica, Lycopodium clavatum, Thalictrum aquilegiifolium, Pyrola rotundifolia, Scorzonera purpurea, Stipa pulcherrima) and not protected but locally rare or data-deficient species (e.g., Myosurus minimus, Thalictrum simplex, Sisymbrium loeselii, Camelina microcarpa, Potentilla collina, Trifolium striatum, Geranium pratense, G. dissectum, G. divaricatum, Viola pumila, Epilobium roseum, Myriophyllum spicatum, Pimpinella major, Berula erecta, Trinia ramosissima, Centaurium pulchellum, Nepeta cataria, Limosella aquatica, Veronica scutellata, Orobanche arenaria, Utricularia vulgaris, Galium elongatum, Cephalaria transsylvanica, Dipsacus fullonum, Xanthium saccharatum, Alisma lanceolatum, Elodea canadensis, Potamogeton pectinatus, P. berchtoldii, P. lucens, P. nodosus, Zannichellia palustris, Sisyrinchium bermudiana, Melica picta, Elymus elongatus, Leersia oryzoides, Typha laxmannii, Eriochloa villosa) are presented. This chapter contains data on 246 species from which 8 are new for the flora of the Tornense flora region and 47 for its subregion, the Putnok Hills. Further contributions to the distribution data of Atlas Florae Hungariae are presented in Electronic Appendix. This section contains raw occurrence data of 169 species.

Contributions to the Atlas Florae Hungariae VIII.
238-261Views:258The current paper is the 8th in the series aiming to contribute with new distribution data to the maps published quite recently in Atlas Florae Hungariae. Distribution data of 539 plant taxa from 157 flora mapping units is presented in this study, most of them are located in the western half of the country. As a result of systematic surveys, more than 190 new species were found in a single flora mapping quadrat. In another survey along some asphalted roadsides Puccinellia distans was found as a new species for 68 flora mapping grid units. All these indicate the necessity of further systematic research and publication of floristic results in papers like the “Contributions…” series. Most of the enumerated taxa are frequent, treated usually as weeds, but some of them are sparse and scattered or rare in Hungary (e.g. Nigella arvensis, Vaccaria hispanica, Rumex pulcher, Urtica urens), and in some cases they are legally protected plants in Hungary (e.g. Asplenium adiantum-nigrum, Dryopteris affinis, Gymnocarpium dryopteris and Huperzia selago). We also listed some casual alien plants and naturalized species that were not mentioned in the last neophyte list of Hungary (e.g. Acer cissifolium, Cyperus alternifolius, Gaillardia aristata, Galanthus elwesii). In the Outlook we pointed out the insufficient survey of some synanthropic (urban) habitat types in Hungary, like verges, gardens and flowerbeds that can be the hotbed of established species or can serve as stepping stones for potential invaders.

Spreading of native Spergularia species along roadsides of Transdanubia (NW Hungary)
141-150Views:186During the systematic floristic research along Transdanubian roads (NW Hungary) since 2013, two native halophyte Spergularia species has been found. Due to the well known spreading near motorways in Eastern-Central Europe, the appearance of Spergularia marina along roads in north-western Hungary is not a surprise. Occurrences of the species were registered along fourteen main roads. Some of the stands are very rich where S. marina forms single-species lines along the asphalt edge. The spreading of Spergularia media along roads is yet much less intensive. Four stands were found near the motorways M1 and M7, main road 74, and the common section of the main road 86-87. Both species are native in the Hungarian plains, being specific elements of Pannonic alkali grassland associations, however, their secondary migration along road edges is promoted by road salting, intensive management of roads and increased vehicle traffic. In this paper, we specify secondary occurrences of the two Spergularia species, discuss their ecological and abiotic circumstances and publish corresponding distribution maps. Due to recognition problems in Spergularia, a corrected determination key was provided.

Contribution to the distribution of Epipactis species in the Keszthely Mts
8-14Views:115In this paper I present occurrence data of Epipactis species in the Keszthely Mts which were collected during the last four years. Ten species had literary or herbarium data from the area previously, all of them has been confirmed (Epipactis atrorubens, E. helleborine, E. leptochila, E. microphylla, E. moravica, E. muelleri, E. palustris, E. purpurata, E. nordeniorum, E. voethii) and another five species (Epipactis albensis, E. neglecta, E. peitzii, E. pontica, E. tallosii) furthermore a hybrid (Epipactis ×reinekei) were found newly on the area.

Contributions to the distribution of Arabis nemorensis (Cruciferae) in Hungary
155-169Views:117Arabis nemorensis is a poorly-known species with sparse and mostly uncertain literature records in Hungary. A complete list of its known occurrences was presented in Soó’s synopsis in 1968. A few new records of this taxon have been reported since then. In the present study all literature records were evaluated by means of revision of Hungarian herbarium materials. Several vouchers were succesfully traced, and their identity as A. nemorensis was confirmed (Baja, Ercsi, Lesenceistvánd, Miskolc, Nagykanizsa, Szigetújfalu). In other cases, the putative vouchers belonged to A. hirsuta or A. sagitatta, thus the corresponding literature records proved to be erroneous (Balatonmáriafürdő-alsó, Gyenesdiás, Kőszeg, Vasboldogasszony, Zalaújlak). On the other hand, hitherto unknown Hungarian localities of A. nemorensis were revealed, specifically in the Bükk Mts. (Eger, Kács), the Bakony Mts. (Márkó), in the western Balaton region (Hahót, Hévíz, Keszthely-Fenékpuszta, Nyirád, Tapolca) and the Hungarian Plains (Csákvár, Debrecen, Egeralja, Fertőd-Eszterháza, Kiskőrös, Lébény, Ócsa, Sárszentmihály, Szigetszentmiklós). The species appeared to be new for the phytogeographical regions Bakonyicum and Nyírségense. Additionally, a few specimens of A. nemorensis collected outside the territory of present-day Hungary were revised in BP. The historical occurrence of the species at Torja (Turia in Romania) is documented by two specimens (Schur, 1853, as A. gerardi; Jávorka & Keller, 1943, as A. hirsuta). Another specimen that was collected in 1879 at Óbecse (Bečej) and labelled as A. glastifolia by Kovács was found to be A. nemorensis too. Since the identity of Schneller’s literature record (1858) from Futak is uncertain, Kovács’s specimen is currently the only, though historical record of this species from Vojvodina province in Serbia. Further specimens of A. nemorensis were discovered in the collections of Lengyel. They were collected and labelled as A. sagittata near Pomogy (Pamhagen) in 1910 (and questionably in 1919), probably representing the first gathering of A. nemorensis from Burgenland state in Austria.
