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

    In 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.

    The 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 azureaCentunculus minimusEuphorbia strictaHypericum humifusumSagina apetala), and in some cases they are legally protected species in Hungary (e.g. Asplenium adiantum-nigrumDryopteris affinisFestuca dalmatica, Gymnocarpium dryopteris, Urtica kioviensis).

  • Flowering phenology and distribution pattern of Lizard Orchids (Himantoglossum)

    Hybridization 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. caprinumH. montis-tauri - H. comperianum, H. hircinum - H. adriaticumH. 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 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).

    The main aim of the present work is to contribute with new data to the distribution maps published recently in Atlas Florae Hungariae. Occurrence data of 297 vascular plant taxa from 247 flora mapping quarter quadrates (CEU) are presented. This floristic paper is somehow unusual because besides the occurrence data of rare or sporadic taxa (e.g. Armoracia macrocarpa (Waldst. et Kit.) Kit. ex Baumg., Samolus valerandi L., Epipactis voethii Robatsch), frequent, but more or less underrepresented taxa (e.g. Ranunculus ficaria L., Viola kitaibeliana Roem. et Schult., Gagea villosa (M. Bieb.) Duby), as well as alien taxa (e.g. Cymbalaria muralis G. Gaertn., B. Mey. et Scherb., Potentilla indica (Andrews) Focke, Tragus racemosus (L.) All.) are also enumerated, since our intention was to fill the – sometimes evident – gaps in the Atlas.  The name initials of the author(s) who actually found the given occurrence are presented in brackets at each record.

    The 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 dioicaBupleurum pachnospermumCarex rostrataCeratocephala testiculataCicuta virosaCirsium boujartiiEpipactis moravicaLycopsis arvensisParnassia palustrisPyrus nivalisRumex kerneriRumex pulcherSilene nemoralisStellaria alsineTeucrium botrysVicia lutea), rare or data-deficient alien taxa (e.g. Nonea luteaPanicum dichotomiflorumSilybum marianum) as well as frequent but more or less underrepresented taxa (e.g. Eragrostis minorHeliotropium europaeumSaxifraga 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.

Occurrence data of rare native taxa (e.g. Marsilea quadrifoliaSalicornia prostrataStellaria palustrisPotentilla patulaAlthaea cannabinaLythrum tribracteatumAjuga laxmanniiPlantago schwarzenbergianaAlisma gramineumGagea bohemicaG. szovitsii), rare or data-deficient alien taxa (e.g. Chorispora tenellaThladiantha dubiaSenecio vernalis) as well as frequent but more or less underrepresented taxa (e.g. Scleranthus annuusVicia hirsutaV. lathyroides) are also enumerated. In case of the most common species we provided the CEU codes only.

  • Multiclavula mucida (Basidiomycota) and other cryptogamic taxa in the Hungarian flora

    The 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.

  • Data on the distribution of some protected plant species and on their presence in secondary habitats

    In 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).

    In this study we report relevant occurrence data of 49 species and hybrids and their habitats from the Great Plain registered in the period between 2011 and 2017. Due to importance for nature conservation, we present additional data of further 13 species. Most of the data are originated from riverine oak-elm-ash forests of South East Hungary (from the region of Gyula, Békéscsaba, Doboz settlements). The most important result of our study is the rediscovery of Gagea minima and Dictamnus albus. Besides, we report new occurrence data for the Great Plain (Alföld), as well as for the flora of the microregions in questions (e.g. Draba muralisNicandra physalodesCystopteris fragilis) and also present the data of the regionally endangered species (e.g. Inula heleniumOphioglossum vulgatum). Some rare weed taxa (e.g. Calepina irregularisCardamine impatiens), spreading adventive taxa (e.g. Chorispora tenellaEuphorbia maculataPhytolacca americanaPh. esculentaSicyos angulata) and in surveys rather underrepresented species (e.g. Loranthus europaeus, Arabis hirsutaRumex confertus) are reported too.

    This 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 negundoElaeagnus angustifoliaXanthium strumarium). Out of the newly registered species six native species inhabits natural habitats (Carex flaccaCeratocephala testiculataGlycerrhiza echinata, Gypsophila paniculataKochia lanifloraMarrubium vulgare), whereas five species represents the weed flora (Anthemis ruthenicaChenopodium ficifoliumEragrostis pilosaSenecio vernalisXanthium 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 alopecuroidesLimonium gmelini subsp. hungaricumSalsola kaliScirpoides holoschoenusTrifolium 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 frondosaImpatiens glanduliferaPhytolacca esculentaXanthium 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.

    The 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).

    This 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.

    This 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 pinnatumCampanula bononiensisClematis rectaElymus hispidusLychnis viscaria, Ranunculus illyricusSanguisorba minorStipa spp., Teucrium chamaedrysTrifolium alpestreVinca 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).

    In this paper, I present chorological data on the plants growing on the alluvial plain of the Sárvíz river in eastern Transdanubia, Hungary. Species characteristic of reed and sedge marshes, salt lakes and alkali flats, as well as remnants of hardwood forests and mesoxeric grasslands are listed in the enumeration. Since 2004, I have confirmed the occurrence of 50 species previously not recorded in the study area. Here, I report the species names, followed by data on the locality: the name of the township, the geographical name of the locality, and the code(s) of both grid systems, the Central European Flora Mapping System (CEU) and the UTM. Sites where I observed or collected the species after 2004 are in bold. Names of species new to the study area are underlined.

    The fifth European occurrence of the moss species Bruchia flexuosa possessing a holarctic distribution range with a North American centre was encountered in Hungary. Outside of the North American continent only two Asian (both from Japan) and four European occurrences from four different countries (Italy, Austria, Slovenia, Croatia) have hitherto been reported. Apart from the recent Japan findings and the Croatian record observed in 1987, all other European records date back to the 19th century. Our paper reports the circumstances of the Hungarian occurrence along with a short descriptions and photographic illustrations of both the species and its habitat.
