The flora of the Sárvíz plain (Mezőföld, Hungary)
207–226Views:331In 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.

Contributions to the Atlas Florae Hungariae VI.
87-102Views:266The 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.

Hungarian localities of Himantoglossum adriaticum and its land-use history
84–94Views:185Himantoglossum adriaticum H. Baumann is a Natura 2000, CITES species and strictly protected plant in Hungary. During my field work (1992–2016) I realized some similarities in the characteristics of the habitats where the plant grows, so I wanted to know the land use history of the areas in question. The H. adriaticum population of Keszthely Hills was studied the longest time. There were annually 7–78 inflorescences between 1992–2016. Recently two further localities were found in Keszthely Hills. They grow in the edges of grasses used earlier as pasture, minor roadside verges and nearby abandoned vineyards. The largest population can be found in Sümeg region, majority of the individuals are along a paved road. Among the estimated 1000–2000 individuals 10 (2012) to 214 (2014) flowered. In Kőszeg, the lizard orchid grows in abandoned vineyards and in old traditional orchards. The maximum number of inflorescences was 165 (2016). In Bakony Hills its habitats are vineyards and orchards abandoned approximately 50 years ago. The size of H. adriaticum population here is nearly the same as in the Keszthely Hills. Four out of the five populations are growing on sites used as vineyard or orchard already in the years of the First Military Survey. The only exception is the population of Sümeg region. Every habitat is threatened by spontaneous forestation, but the species is able to find new habitats, so we do not worry about the drastic decline of the individuals in Hungary.

Contributions to the Atlas Florae Hungariae III.
122-146Views:527The 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.
