Notes to the vascular flora of Sopron Mountains and its foreground
187–194Views:278Records of 26 vascular plant species from the territory of Sopron Mountains (16 species) and Sopron Basin (11 species) are presented. Our field works (between 2014 and 2020) focused on some localities at the eastern and southern parts of the region. Tetragonolobus maritimus is new for the Sopron Mts, whereas Ajuga chamaepithys and Lycopsis arvensis are new for the Hungarian part of the hills. Some protected plants like Agrostemma githago, Gentianopsis ciliata and Sesleria uliginosa were rediscovered in the region. Comments about all species and their local chorology are added. A remarkable degradation process of bogs around Harka village, caused mainly by insufficient water supply of meadows, was observed. The spread of occurrences of several naturalized weed such as Aegilops cylindrica, Galium parisiense, Geranium rotundifolium, Kochia scoparia, Lepidium virginicum, Oenothera salicifolia, Sagina apetala subsp. apetala and Verbascum lychnitis was noticed. The most surprising observations refer to Galium parisiense; the spread of the species by transport had no precedent in Hungary before.

Floristic data from the Great Plain of Hungary (Alföld)
304–316Views:150In 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 muralis, Nicandra physalodes, Cystopteris fragilis) and also present the data of the regionally endangered species (e.g. Inula helenium, Ophioglossum vulgatum). Some rare weed taxa (e.g. Calepina irregularis, Cardamine impatiens), spreading adventive taxa (e.g. Chorispora tenella, Euphorbia maculata, Phytolacca americana, Ph. esculenta, Sicyos angulata) and in surveys rather underrepresented species (e.g. Loranthus europaeus, Arabis hirsuta, Rumex confertus) are reported too.

Contributions to the Atlas Florae Hungariae VI.
87-102Views:204The 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.

Contributions to the Atlas Florae Hungariae XIII.
85-88Views:57898The 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).

Spreading of native Spergularia species along roadsides of Transdanubia (NW Hungary)
141-150Views:152During 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.

Contributions to the Atlas Florae Hungariae IX.
253–256Views:271The 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).

Continuing spread of Plantago coronopus along Hungarian roads
19–26Views:480In the course of our research of Hungarian transport routes, we observed an intensive spread of the Atlantic-Mediterranean Plantago coronopus L., a recently established species in Hungary. Between 2017 and 2019, it was detected in 47 flora mapping quadrats, which increased the total number of occurrences to 81 since 2013. Besides motorways, the main Hungarian transport routes were involved as well. 26 occurrences have been recorded along the roads 4/E60, E573, 8/E66, 86/E65 and 87, which are severely affected by international traffic. However, on routes avoiding international transit traffic, the species’ occurrences are still rare. In some cases, the predominant direction of traffic appeared to influence the formation of new stands. It is very likely that the first individuals that appeared along the section of the M86/E65 motorway between Szombathely and Hegyfalu in 2019, arrived primarily by northbound traffic, rather than along the road 86, which runs parallel to it only a few hundred meters away. Likewise, it seems certain that the spread of the species along the roads M1/E60, E75 (Mocsa, Tata, Páty) and M7/E71 (Fonyód, Balatonlelle, Kajászó) as well as the road 8/E66 (Bakonygyepes, Veszprém) is due to reproduction of older extensive local populations. At several localities along the outer bend of roundabouts or near the exits of motorways, a dispersal role of intense winter road salting was also observed. The largest populations were located mostly along ditches, next to the (often bare) lane of roadbeds that are heavily affected by mechanical and osmotic stress. The majority of stands were found within a 3 meters wide belt along the asphalt strip (5 meters was measured in the lawn of a cemetery once). Since the species is present continuously at several localities since 2013, it is considered as naturalised in Hungary, and its further spread can be confidently predicted. The current status of the species in Hungary is naturalised (non-trans¬former) neophyte.

Contributions to the Atlas Florae Hungariae III.
122-146Views:197The 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.
