  • 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.

  • Floristic data from the northern edge of the floristic region ‘Crisicum’ (NE Hungary)

    This paper reports new floristic data of 161 taxa. Most of these data were collected between 2011–2013, and are coming from the northern edge of the floristic region 'Crisicum', the NE part of the Great Hungarian Plain, which is a little-known area from a floristic point of view. 43 CEU quarterquadrates and territory of 35 settlements are represented by the dataset. The paper reports occurrence localities for legally protected (e.g. Ophioglossum vulgatum, Stellaria palustris, Ranunculus polyphyllus, Thlaspi jankae, Lathyrus palustris, Elatine spp., Lycopsis arvensis, Lindernia procumbens, Cirsium brachycephalum, Cyperus pannonicus), strictly protected (Armoracia macrocarpa, Vicia biennis) and some little-known (e.g. Cardamine parviflora, Reseda luteola, Melilorus dentatus, Veronica catenata) taxa. Numerous data of alien species (e.g. Lepidium densiflorum, Euphorbia maculata, Sicyos angulatus, Erechtites hieracifolia, Elodea nuttallii, Elymus elongatus, Eleusine indica, Sorghum halepense, Eriochloa villosa) are also published. The most important data are documented by voucher specimens deposited in herbarium of Debrecen University (DE).

    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).

  • Floristic data from the Great Plain of Hungary (Alföld)

    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.

    The present study reports the occurrence data of some rare and legally protected vascular plant species, collected at Tolna county and the northern part of Baranya county during field work between 2012–2013. Among the reported floristic data, the occurrence of Ranunculus lingua, Potentilla rupestris and Malva alcea are new for Tolna county. Further rare species such as Allium angulosum, Althaea hirsuta, Erodium ciconium, Galium rubioides, Glycyrrhiza echinata, Lathyrus palustris, Lathyrus sphaericus, Myagrum perfoliatum, Salvinia natans, Urtica kioviensis and Vicia lutea were also registered on the studied area.

    Results of nearly two decades of floristic research in the territory of Heves–Borsod Hills (Tar­na-vidék) and the northern foreground of the Bükk Mts are presented in this paper (altogether 4421 re­cords; BÁ: 1665, SJ: 2752). Several old literature records – partly supported by vouchers – are confirmed, e.g. Hypericum elegans and Lappula heteracantha from the Uppony Gorge, as well as Cephalaria tran­s­syl­va­ni­caCypripedium calceolusDiplotaxis erucoides and Plantago indica from the Heves–Borsod Hills and the nort­hern foreground of the Bükk Mts. Other former literature records (partly from the authors) are re­vi­sed. These revisions are mainly due to changes in taxonomic concepts of some genera in new keys (Carex, Cha­maecytisus, Epipactis, Molinia, Sorbus). Old literature and herbarium records of other significant taxa (Onos­ma visanii, Scutellaria columnae, Sorbus sp., Utricularia bremii/minor) are revised too. The new occurrence of Ferula sadleriana in the Uppony Gorge is probably the result of intentional seed dispersal. Of the many rare plants listed in our paper some are new for the flora of the region under study: Ag­ri­mo­nia procera, Alchemilla micans, Asplenium adiantum-nigrum, Astragalus austriacus, A. exscapus, Blysmus compressus, Carex appropinquata, C. cespitosa, Catabrosa aquatica, Centarea indurata, Dactylorhiza × as­cher­soniana, Epipactis voethii, Epipogium aphyllum, Equisetum hyemale, Festuca drymeja, Gagea bohemica, Gly­ceria nemoralis, Hesperis sylvestris, Myosotis caespitosa, Phegopteris connectilis, Platanthera chlorantha, P. × hybrida, Rosa gizellae, Scilla kladnii, Senecio doria, Solanum villosum, Taraxacum palustre, Triglochin pa­lustre. Two phytocoenological relevés representing the habitats of Myosotis caespitosa and Spiraea me­dia are presented. Currently known local distribution of some montane and forest-steppe elements are shown on maps.

  • Data on the occurrence of sedge species (Carex, Cyperaceae) in and around South Nyírség (East Hungary)

    We 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.

  • 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 our paper, we publish the most important new floristic data from the region of Tokaj Hills and Zemplén Mountains (incl. Szerencsköz, Hernád-mente, Bodrogköz, Tatkaköz, Harangod) from the last ten years. During this period, we discovered two new protected species (Asplenium javorkaeanum, Epipactis nordeniorum) in the Zemplén Mountains and seven new protected species (Cep­ha­lan­thera damasonium, Cirsium brachycephalum, Epilobium palustre, Epipactis palustris, Lycopodium cla­va­tum, Pyrola rotundifolia, Polystichum aculeatum) in the Hungarian part of Bodrogköz. We found new lo­ca­tions of several rare species (Epipactis exilis, Dryopteris expansa, Blechnum spicant, Androsace maxima, Orchis coriophora, Orchis purpurea, Dactylorhiza sambucina, Sonchus palustris, Cicuta virosa). We confirmed the occurrence of four species, which have not been detected for decades (Sedum his­pa­nicum, Erysimum wittmannii subsp. pallidiflorum, Pseudolysimachion spurium, Botrychium lunaria).

  • 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.

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 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.

    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 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).

    The present study reports the occurrence data of 54 vascular plant taxa, collected at various localities in Hungary during floristic, vegetation and ecological field surveys between 2000 and 2013. In some cases, phytosociological relevés were prepared to characterize the local coenological properties of the species. Many of these species are included in the „Red list of the vascular flora of Hungary” (e.g. Carthamus lanatus, Sedum caespitosum, Spiranthes spiralis and Trifolium micranthum). Some of them (e.g. Apium repens, Dianthus diutinus, Epipactis bugacensis and Ranunculus psilostachys) are rarities in the whole country. Our findings suggest that conservationists should focus not only on the maintenance of semi-natural habitats but also on the investigation of secondary habitats (e.g. river embankments, temporary pools on arable fields) in order to maintain the total species diversity of the landscape.

  • Contributions to the flora of railway-side pioneer habitats on Tiszántúl region

    Verges have considerable importance to preserve diversity in arable landscape. The modernized railway embankments are a great surface to the spread of native pioneer or adventive (invasive) plant species. The new data are about the flora of railway embankments mainly from Tiszántúl region. I present some species found on railway verges (e.g. Equisetum ×moorei, Equisetum ramosissimum, Lycopsis arvensis, Euphorbia maculata, Lepidium densiflorum Tragus racemosus, Vulpia myuros). An especially important new data is the refinding of Galium humifusum in Hungary. Locally non-native and adventive species can use the blanketing materials (sand or gravel) of railway embankments as dispersal corridor and colonize them. The railwayside habitats could contribute to the conservation of rare native pioneer species.

  • The Sea milkwort (Glaux maritima) in the Carpathian Basin

    337

    Sea 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.

    The present paper focuses on the aquatic and Nanocyperion vegetation of the Danube flood­plain. Most of the data show the results of the surveys in 2019 at low water levels. The Nanocyperion and aquatic vegetation of the Komárom-Esztergom County section is relatively well researched com­pared to the Fejér County section which was previously poorly known. In the last decade, two rare spe­cies – Hippuris vulgaris and Hydrocharis morsus-ranae – have disappeared between Gönyű and Neszmély (Komárom-Esztergom County). In contrast, several new invasive plants have appeared: Salvinia molesta, Myriophyllum aquaticum, Limnobium laevigatum, and Crassula helmsii (first record from Hungary). Vallisneria spiralis and Elodea canadensis were detected again after several decades. Elodea nuttallii and Azolla sp. have become more widespread and abundant than previously. New and uncommon Nanocyperion species were the native and protected Lindernia procumbens and the inva­sive Lindernia dubia. New invasive plants in the studied Danube sections were: Cyperus esculentus, Euphorbia maculata, and Eleusine indica. The native Veronica catenata and Schoenoplectus triqueter have become more wide­spread than before. Polygonum graminifolium was an interesting find of open pebble surfaces in several parts of the examined area, which has no recent records in Hungary from before 2015 (published here).

    During the last four years (2014–2017) that have passed since my last publication, I have been collecting 25 000 new floristic data for the territory of the Danube–Drava National Park. The most valuable and interesting records of 116 taxa are presented here, e.g. those of the strictly protected Digitalis ferruginea and Paeonia banatica, and the protected species Polystichum lonchitis, Dryopteris affinis, Doronicum orientale, Helleborus dumetorum, Corydalis intermedia, Spiraea media, Veratrum nigrum. New records of not protected but rare species, such as Lycopsis arvensis, Silene dichotomaTeucrium botrys, Thladiantha dubia, Vicia lutea, Hypochoeris radicata are also enumerated. Some curiosities are mentioned as well, including the sizes of the biggest (and probably the oldest) Crataegus monogyna, Hedera helix, Ruscus hypoglossum and Ruscus aculeatus individuals that were found during my field work.
