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.

Contributions to the Atlas Florae Hungariae XIII.
85-88Views:58008The 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 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.

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).

Multiclavula mucida (Basidiomycota) and other cryptogamic taxa in the Hungarian flora
173–184Views:325The 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 VI.
87-102Views:266The current paper is the sixth one in the series aiming to contribute with new distribution data to the distribution maps published recently in Atlas Florae Hungariae. Current occurrence data of 389 vascular plant taxa from 117 flora mapping quadrates (CEU) are provided. New records are indicated from different regions of Hungary; however, most occurrences are located in the North Hungarian Mts and from the city of Szolnok and Western Hungary. Occurrence data of rare native taxa (including data of Equisetum fluviatile, Galium rivale, Gladiolus imbricatus, Hypericum maculatum, Persicaria bistorta, Potentilla inclinata, Ranunculus lingua, Rhinanthus rumelicus, Trifolium fragiferum subsp. bonannii, Viola pumila), rare or data-deficient alien taxa (e.g. Amaranthus blitum subsp. blitum, Cymbalaria muralis, Elymus elongatus, Euphorbia peplus, Heracleum sosnowskyi, Impatiens balfourii, Lepidium densiflorum, Rhus typhina, Telekia speciosa), as well as frequent but more or less underrepresented taxa (e.g. Carex otrubae, Chenopodium polyspermum, Crepis tectorum, Filipendula vulgaris, Petrorhagia prolifera, Poa palustris) are also enumerated. In case of the most common species we provided the CEU codes only.

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.

Data on the occurrence of sedge species (Carex, Cyperaceae) in and around South Nyírség (East Hungary)
165-198Views:423We provide floristic data on a total of 38 sedge species in the area of South Nyírség and its immediate surroundings. We also detected some populations of previously undescribed or rare species in the Hungarian Great Plain, such as Carex buxbaumii, Carex hartmanii, Carex umbrosa, and Carex paniculata. We report several new occurrences of species with little literature data from the area, such as Carex brizoides, Carex michelii, Carex pallescens, Carex elongata. However, during the last 13 years, we were not able to detect seven species previously mentioned in the literature. Herbarium data confirmed that some of the older Carex nigra occurrences for the area actually refer to Carex cespitosa. Based on herbarium data and the literature, we think that local data on Carex pairaei may largely refer to Carex divulsa subsp. leersii and/or Carex spicata. Contrary to many pieces of literature, Carex vulpina was not observed inside the sandy area.

Floristic records from Northern Hungary III. Zemplén Mts
109–172Views:479We report new floristic data collected from the Zemplén Mountains between 2004–2022. Altogether, 1215 occurrences of 133 species were recorded from 33 Central European Flora Mapping quadrats. We present occurrences of so far not reported or rare species, e.g., Carex appropinquata, C. cespitosa, C. disticha, Centaurea stenolepis, Scabiosa columbaria, Tephroseris aurantiaca. We put special emphasis on occurrence data of geobotanical importance, such as Anthriscus nitidus, Echium maculatum, Lunaria rediviva, Nepeta pannonica, Oreopteris limbosperma, Petasites albus, Primula elatior, Thlaspi jankae, Veronica montana, as well as newly rediscovered species based on archive data: Cirsium rivulare, Parnassia palustris. We mention common species, which are lacking data from the area, e.g., Adoxa moschatellina, Allium flavum, Cardamine amara, Dipsacus fullonum, Galanthus nivalis. Moreover, we report numerous new occurrences of taxa typical to the Zemplén Mts.: Aruncus dioicus, Huperzia selago, Lycopodium annotinum, Securigera elegans etc. We complete the enumeration with additional data from the literature and herbaria.

Contributions to the Atlas Florae Hungariae IX.
253–256Views:332The 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).

Contributions to the Atlas Florae Hungariae III.
122-146Views:527The current paper is the third one in the series aiming to contribute with new distribution data to the distribution maps published recently in Atlas Florae Hungariae. Current occurrence data of 558 vascular plant taxa from 186 flora mapping quadrates (CEU) are presented. New records are indicated from different regions of Hungary; however, most occurrences are located in the North Hungarian Mts. Occurrence data of rare native taxa (e.g. Marsilea quadrifolia, Salicornia prostrata, Stellaria palustris, Potentilla patula, Althaea cannabina, Lythrum tribracteatum, Ajuga laxmannii, Plantago schwarzenbergiana, Alisma gramineum, Gagea bohemica, G. szovitsii), rare or data-deficient alien taxa (e.g. Chorispora tenella, Thladiantha dubia, Senecio vernalis) as well as frequent but more or less underrepresented taxa (e.g. Scleranthus annuus, Vicia hirsuta, V. lathyroides) are also enumerated. In case of the most common species we provided the CEU codes only.

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.

Contributions to the Atlas Florae Hungariae II.
227-252Views:344The present article is the second part of the series aiming to contribute with new data to the distribution maps published recently in Atlas Florae Hungariae. Current occurrence data of 612 vascular plant taxa from 283 flora mapping quadrates (CEU) are presented. New records are distributed over the entire Hungary, however, most are localised in the North Hungarian Mts. Occurrence data of rare native taxa (e.g. Antennaria dioica, Bupleurum pachnospermum, Carex rostrata, Ceratocephala testiculata, Cicuta virosa, Cirsium boujartii, Epipactis moravica, Lycopsis arvensis, Parnassia palustris, Pyrus nivalis, Rumex kerneri, Rumex pulcher, Silene nemoralis, Stellaria alsine, Teucrium botrys, Vicia lutea), rare or data-deficient alien taxa (e.g. Nonea lutea, Panicum dichotomiflorum, Silybum marianum) as well as frequent but more or less underrepresented taxa (e.g. Eragrostis minor, Heliotropium europaeum, Saxifraga tridactylites) are also enumerated, since our intention was to fill the gaps in the Atlas. Remarcable contribution on the occupied territory of Ranunculus illyricus and Spergula pentandra in the Nyírség region (E Hungary), and on the Hungarian distribution of expanding alien weed Senecio vernalis are also presented.

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).

Some floristic data from surroundings of Kötcse (South Transdanubia, West Outer Somogy)
74-80Views:129There are very few published and documented floristic data from the hills of the SW region of Hungary called 'Outer Somogy'. This paper present the occurrence data of 31 vascular plant species from the western part of this region. Among them 14 taxa are legally protected and further 17 taxa are sporadically occurring. The records were collected within the administrative area of villages Karád, Kereki, Kötcse, Nagycsepely, Szólád (Nezde) and Teleki. Most data were recorded in 2014. This is the first report on the occurrence of 1) Neotinea ustulata subsp. aestivalis in South Transdanubia, and 2) Epipactis microphylla and E. tallosii in Outer Somogy. Data provided on the occurrence of Cirsium boujartii on the northwestern border of the distribution area of this insufficiently known species.

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.

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.

Contributions to the Atlas Florae Hungariae I.
101–115Views:262The 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.

Floristic data from Lengyel–Hőgyész Natura 2000 site (SW Hungary)
31–38Views:168This paper presents occurrence data of 169 taxa from the Lengyel–Hőgyész Natura 2000 site (HUDD20026) which is on the southern part of Tolna Hills, SW Hungary. Data were collected during three years (2015, 2016, 2017), on different sites annually. The presented data contribute to the distribution dataset of Atlas florae Hungariae. Regionally rare or sporadic species (e.g. Asplenium scolopendrium, Asplenium trichomanes, Polystichum setiferum, Doronicum hungaricum, Paris quadrifolia, Scilla vindobonensis) are enumerated. Presence of Epipactis leptochila subsp. neglecta and Platanthera chlorantha were not registered from this site before. Subspecies of Carex divulsa are also studied on this site – distribution of these infraspecific taxa have not been mapped recently in Hungary.

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.

Distribution and flora of areas with alkaline and saline soils in the Mezőföld, Hungary
39-61Views:237Areas 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.

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.
