Data to the flora of Heves–Borsod Plain I. Distribution of forest, forest steppe and steppe elements
16-65Views:412This 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).

Distribution and conservation status of forest plant species in sand oak forests of the Danube–Tisza Interfluve
129–140Views:591In this article we summarise the floristic data collected during our research in oak forests in the northern part of ‘Kiskunság’ since 1998. Between 2020 and 2024, we systematically visited and mapped the forest stands in the region, which have been continuous since the First Military Survey (late 18th century). A total of 100 forest patches were identified as semi-natural pedunculate oak, covering a total of 865 hectares, and floristic data could be collected in 94 of them. The data were supplemented by scattered occurrences found during the survey. A total of 1207 occurrences of 96 forest and forest edge species were recorded in the stands. Of these, 214 occurrences of 81 species are new compared to the Hungarian Floristic Mapping data. Species were grouped according to habitat preference and regional vulnerability. In total, 23 species were classified as threatened and 37 as critically endangered. Without active conservation interventions, these species could become extinct in the ’Kiskunság’ within a few decades.

Astragalus vesicarius and other new taxa to the flora of the Vértes Mountains (Hungary, Transdanubian Mts)
195–199Views:565A conservation survey on the condition of steppe and forest-steppe habitats in the Vértes Mts revealed several plant species from the flora of the area that have not been reported before. From a phytogeographical point of view, the most important is Astragalus vesicarius, whose small population in the Vértes fits very well into the native distribution pattern of the species in Hungary. Another important steppe plant is Stipa dasyphylla, which is found in two locations in the Vértes Mts. Besides other taxa of conservation interest (Orobanche teucrii, Phelipanche purpurea, Rosa hungarica), some under-recorded species (Cerastium tenoreanum, Stellaria pallida), and some spreading weeds (Elymus elongatus, Euphorbia lathyris) enrich our knowledge of the flora of the area.

Remnants of closed oak woods on loess in the Mezőföld (Pulmonario mollis-Quercetum roboris Kevey 2008)
66–93Views:431The phytosociological characterization of closed oak forests occurring in the loess-covered part of Central Hungary (Mezőföld) is presented. Such forest fragments are found very sporadically in that predominantly treeless region, mostly in semi-dry habitats of north-facing hillsides. This plant community represents an intermediate stage between open steppe woodland (Aceri tatarici-Quercetum pubescentis-roboris) and closed mesic oak-hornbeam forests (Corydali cavae-Carpinetum). Analyses of 20 phytosociological samples using multivariate grouping methods (cluster analysis, principal coordinates analysis) showed a clear difference between these samples and samples of similar communities occurring in the area. In the species composition the characteristic elements of dry and mesic oak forests (Quercetea pubescentis-petraeae, Quercetalia cerridis, Aceri tatarici-Quercion and Fagetalia, respectively) played a major role. On the other hand, dry grassland species (Festuco-Brometea, Festucetalia valesiacae, Festucion rupicolae, etc.) were much less significant than in steppe woodlands. In terms of chorology, European and sub-Mediterranean floristic elements were dominant in the samples, while the proportion of continental elements was substantially smaller than that in steppe woodlands. As a result, our samples were identified with the plant association Pulmonario mollis-Quercetum roboris Kevey 2008, which is classified into the suballiance Polygonato latifolio-Quercenion roboris Kevey 2008 in the phytosociological system.

Ceratocephala testiculata (Crantz) Roth and further data to the flora of the foothills of Bükk Mts.('Bükkalja', NE Hungary)
81-142Views:423This 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 to the flora and geobotany of Kisalföld (Lesser Plain) region, NW Hungary
235-253Views:312Lesser Plain (Kisalföld) – divided among three countries (Austria, Hungary and Slovakia) – is the westernmost part of the lowland areas of the Pannonian Basin. Present paper provides a résumé of the authors’ floristic work from the Hungarian part of the area, describing localities, habitats and regional phytogeography of 57 taxa altogether. The localities were listed according to the classification of small geographic regions. The most important results of the study are as follows:
- We recorded 5 species new to the region (Brachypodium rupestre, Bromus ramosus, Hypericum dubium, Lathyrus sphaericus, Tordylium maximum); all of them can be considered as submontane-montane elements.
- We reported several species new to a microregion within the Lesser Plain: montane species in the W-SW part of the Plain (Cirsium rivulare, Dryopteris dilatata, Equisetum telmateia), loess-connected species mainly on the Moson Plateau (Agropyron cristatum, Allium atroviolaceum, Euphorbia salicifolia, Viola ambigua); and occurrences of species on sandy soils near the Lake Fertő (Draba nemorosa, Stipa pennata).
- We explained the known localities of several salt tolerant species (e.g. Carex divisa, Crypsis alopecuroides, Juncus maritimus, Limonium gmelinii, Suaeda pannonica) from the Lake Fertő and its surroundings.
- We assessed the role of the forest management and nature conservational actions in the distribution of some important tree species (Acer tataricum, Betula pubescens, Fraxinus ornus, Quercus petraea, Salix pentandra).
- We discussed the regional nature conservational status of several protected and/or threatened species (e.g. Allium carinatum, Allium suaveolens, Carex strigosa, Hottonia palustris, Potamogeton coloratus, Stellaria palustris) in the Lesser Plain.
The activities of the authors in the surroundings of Győr were supported by monitoring results gained during the Hungarian Little Plain project (LIFE08 NAT/H/000289).

Contributions to the flora of the Heves–Borsod and Uppony Hills and adjacent territories
173–226Views:342Results 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 transsylvanica, Cypripedium calceolus, Diplotaxis 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.

Contributions to the flora of Tolna and Baranya counties IV.
17-33Views:450The authors present the most important floristic data of Tolna and Baranya counties, collected together or separately in the last 15 years, or observed by other data providers. In total, occurrence data of 140 taxa are reported. Most of them are protected species in Hungary, but the list also includes rarer weeds (Adonis flammea, Althaea cannabina, Aphanes arvensis, Bunias orientalis, Legousia speculum-veneris, Vicia lutea) and adventive species (Helminthia echioides, Oxybaphus nyctagineus, Rubia tinctorum). Several species of phytogeographical importance were also found in the forest-steppe vegetation of the loess areas studied. Occurrence of Linaria biebersteinii should be highlighted. L. biebersteinii is a very rare species in the Transdanubian region, and is no longer found in Europe west of this region. The occurrence of Himantoglossum adriaticum is a new contribution to the flora of the southern Transdanubian region.

The flora of the Sárvíz plain (Mezőföld, Hungary)
207–226Views:508In 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.
