Data to the flora of Heves–Borsod Plain I. Distribution of forest, forest steppe and steppe elements
16-65Views:431This 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).

Chorological notes on the vascular flora of Hungary
85-119Views:721The paper presents 1593 current chorological data of 584 taxa (species, subspecies, varietas, hybrids) from Hungary, collected during the last few years. All of these connected also to a total of 184 CEU quadrats. Among the species characteristic to the natural habitats, we highlighted the records of several species protected in Hungary (Adoxa moschatelina, Althaea cannabina, Cardamine parviflora, Centaurium pulchellum, Gagea pusilla, Orobanche reticulata, Potentilla patula, Rosa zagrabiensis, Spergula pentandra, Trifolium diffusum, Valerianella dentata, V. rimosa, Veronica officinalis, Viola collina and V. pumila). In the Northern part of Hungary, we observed the establishment of Cerastium dubium and Ranunculus pedatus at several places along roadsides, which species have been known from the surrounding saline areas for a long time, but their appearance at roadsides is relatively new phenomenon. In addition, Aegilops cylindrica, Crypsis schoenoides, and Fumaria vaillantii subsp. vaillantii were found in one location – each species on roadsides. Along the railway tracks, we found disturbance-tolerant pioneers of rocky grasslands, open sandy and loess grasslands, e.g. many population of the native Androsace elongata, Anthemis ruthenica, Centaurea arenaria, Draba nemorosa, Erodium ciconium, Medicago monspeliaca, Microrrhinum minus, Saxifraga tridactylites and Vulpia myuros were found, as well as numerous ruderalia and the archaeophyt such as Aegilops cylindrica. In addition to the more common species from the urban flora, we present some new data on the occurrence of the rarer Amaranthus blitum subsp. emarginatus, Chenopodium glaucum, Ch. murale, Ch. opulifolium, Ch. vulvaria and Euphorbia peplus. We have also listed some of the rarer field weeds and species that can establish in younger and older old-fields. Bromus secalinus has been found in several places in the northeastern part of Hungary. We also observed Calepina irregularis, Centaurea solstitialis, Centaurium pulchellum, Erysimum cheiranthoides, Filago lutescens, Fumaria officinalis subsp. officinalis, Geranium dissectum, Misopates orontium, Myagrum perfoliatum, Reseda phyteuma, Spergularia salina and Veronica anagalloides populations. Erodium hoefftianum is a member of the natural flora, but is now found only in old-fields. We found some pasture weeds in regions where they are not common (e.g. Bupleurum tenuissimum, Cerastium dubium and Trifolium striatum). The study also presents some species that are data deficient for taxonomic reasons, but not very rare ones (or we don’t know that). This group includes Arabis sagittata, Bolboschoenus glaucus, Bromus commutatus, B. racemosus, B. ramosus, Fumaria vaillantii subsp. schrammii, Ononis spinosiformis subsp. semihircina, Potentilla collina and Viola suavis “white morfotype”. We have drawn attention to the effect of ecological-botanical works on flora-influencing. We found Anthemis ruthenica (species of sandy grasslands) in a mountain meadow, which is probably the result of seeds accidentally introduced by researchers. Finally, the paper provides data on the current distribution of hybrid taxa. A new individual of Betula ×rhombifolia was established in the Mátra Mts. We found some Euphorbia individuals that appeared to be a transitional form between E. esila and E. virgata (E. ×intercedens; Eu. esula subsp. saratoi). We also present some Verbascum and Viola hybrids. Hybrids were determined on a macromorphological basis.

41–52Views:492This paper presents new floristic data from the Putnok Hills (Northern Hungary), collected between 2022 and 2024. We found new localities of several taxa (Gymnocarpium dryopteris, Polystichum aculeatum, Dryopteris carthusiana, D. dilatata, Lychnis coronaria, Dianthus deltoides, D. collinus, Pulsatilla grandis, Hesperis sylvestris, Potentilla rupestris, Chamaecytisus albus, Lathyrus nissolia, Lathyrus palustris, Linum flavum, L. tenuifolium, Polygala major, Gentiana cruciate, Phlomis tuberosa, Pseudolysimachion longifolium, Inula helenium, Jurinea mollis, Centaurea triumfettii, Scorzonera purpurea, Sonchus palustris, Ornithogalum brevistylum, Scilla kladnii, Iris sibirica, Iris aphylla subsp. hungarica, Stipa pulcherrima, Cephalanthera damasonium, Neottia nidus-avis, Platanthera bifolia, Gymnadenia conopsea, Orchis morio, O. tridentata, O. ustulate, O. purpurea, O. elegans) that are legally protected in Hungary.

The flora of the Sárvíz plain (Mezőföld, Hungary)
207–226Views:518In 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.
