  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 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).

  This paper contains the new floristic results of the author from Harangod and SouthCserehát, collected between 2009 and 2013. It presents data on 66 and 48 species respectively. Several new localities of forest-steppe species (e. g. Artemisia pontica, Corydalis cava, Galium odoratum, Lilium martagon, Melica altissima, Thalictrum minus, Viola elatior), meadow species (e. g. Gratiola officinalis, Senecio sarracenicus) and adventiv plants (e. g. Gypsophila perfoliata, Panicum capillare, Typha laxmannii) are published here.

  The 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.

  A 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.

  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.
