Flowering phenology and distribution pattern of Lizard Orchids (Himantoglossum)
157-167Views:121Hybridization is very rare between the species of Himatoglossum genus, despite the fact that it is common in other orchid genera. The reasons for this can be the lack of overlapping distribution areas or the different flowering period of the species. In the paper distribution and flowering data of Himantoglossum species are presented from herbarium sheets or references (sources paper-based or internet). We collected 1001 precisely dated flowering records of 12 species. In case of 6 species (H. adriaticum, H. caprinum, H. comperianum, H. hircinum, H. jankae, H. robertianum) we had sufficient records to calculate the average flowering day and blooming length. According to the collected data the distribution of the species are overlapping except for H. formosum, H. galilaeum and H. metlesicsianum. Studying 55 species pairs, insignificant differences in blooming time were only at 21 species pairs, among them only 5 (H. comperianum - H. caprinum, H. montis-tauri - H. comperianum, H. hircinum - H. adriaticum, H. montis-tauri - H. caprinum és H. jankae - H. calcaratum) have overlapping distribution area. Data on hybridization could be found only at three species pairs among them. From the results we can conclude that in the case of Himantoglossum genus the rarity of hybridization is mostly due to the phenological isolation.

Reseda inodora Rchb. in the Tiszántúl region (East Hungary)
48-54Views:160On 14 August 2012 a small population of Reseda inodora was found in Hegyes-halom kurgan within the administrative boundaries of the town of Mindszent (Csongrád County, CEU: 9487.3). The approximately 50–100-stem-large population of the species lived on the edge of the kurgan, on the sparsely vegetated, weedy fieldmargin. On 19 July 2014 this species has turned up again in this area. In this case it was the biggest amount with some hundred stems and was located on the edge of the mound, which is in the verge of the neighbouring corn field. The Reseda inodora is a new recent protected vascular plant species within the operation area of the Körös–Maros National Park. We propose this species to be included in the regional red list in the category of „CR” (Critically endangered). Other rare weed or pioneer species (Caucalis platycarpos subsp. muricata and subsp. platycarpos, Erodium ciconium, Lappula squarrosa, Melica transsilvanica, Papaver hybridum) have already been found in Hegyes-halom kurgan in the last few years. The results show the importance of kurgans not only in the conservation of natural steppe, loess wall vegetation and steppe shrub species, but in the survival of some endangered weed species as well (e.g. some rare archaeophytes).

Data to the flora of Southern-Nyírség and its surroundings
68–85Views:1728In this paper we provide data on the flora of Monostorpályi, a floristically underrepresented settlement in South-Nyírség and Berettyó–Kálló interfluve, and publish some interesting floristic observations from the Debrecen city area. In our compilation we provide data on 58 plant species. Among the species listed in the enumeration we find taxa from the region not previously reported at all (Lathyrus nissolia, Gagea villosa, Catabrosa aquatica, Potamogeton lucens, P. pusillus). In total, we publish new occurrence data for 16 protected plant species, which are generally typical of the natural habitats of the Nyírség, but are on the decline overall (e.g. Hottonia palustris, Dianthus superbus, Cirsium rivulare, Lychnis coronaria). We also provide data on the distribution of some rare or declining weed species (Anthemis cotula, Myagrum perfoliatum, Agrostemma githago) and confirm the previously known occurrence of some poorly known plant species (Luzula pallidula, Carex hordeistichos). Furthermore, the spread of some alien species (Broussonetia papyrifera, Phyllostachys sp.) is also highlighted.

Multiclavula mucida (Basidiomycota) and other cryptogamic taxa in the Hungarian flora
173–184Views:324The paper deals with the species found during cryptogamic flora mapping in 2023 that are remarkable from a floristic, taxonomic or conservational point of view. We present data from the Bükk Mts of two Trapeliopsis species which appear to be rare in Hungary. Multiclavula mucida, which is apparently a rare basidiomycete lichen species in Europe that prefers humid, montane habitats was discovered in the Mecsek Mts as a new species for the Hungarian flora. Of the knothole moss, Anacamptodon splachnoides, which is now thought to be entomophilic, we communicate the only extant population from Southern Transdanubia. We report the first occurrence of the atlantic-mediterranean Leptodon smithii from the Hungarian side of the Great Hungarian Plain. Numerous data of the corticole Neckera pennata indicate that in Hungary the distributional centre of this species is situated in the county of Baranya in the lowlands. New data from the Bükk Mts underline that in the Pannonian region Buxbaumia viridis is primarily a terricole species of acidophilous beech forests. We communicate the first occurrence from the lowlands of the alien lignicolous Sematophyllum adnatum which is dangerously spreading in Europe, at the same time one of the most vigorous populations in the Pannonian region. The third Hungarian occurrence of Callicladium haldanianum, a species that seems to spread in bogs, as well as the second occurrence of Racomitrium lanuginosum, growing abundantly on an andesite boulder scree in Mátra Mts, are also reported here. Of Phegopteris connectilis we present in photographic documentation the first extant population from Southern Transdanubia, and we discuss whether the first publication from Mecsek Mts is correct or exact. In addition to listing the floristic data, we also briefly discuss the (mis)use of distribution data in the context of climate change, the difficulties of distinguishing the microtaxa of some pteridophytes, e.g. Asplenium adiantum-nigrum agg. and Dryopteris affinis agg., and we correct one of our previously published, erroneous Hedwigia stellata data. Some interesting data of other taxa (such as Leucobryum glaucum, Palustriella commutata, Tetraphis pellucida, Gymnocarpium robertianum, Ophioglossum vulgatum) are also mentioned in the paper.

Data on the distribution of some protected plant species and on their presence in secondary habitats
183-199Views:1828In this paper, I publish my floristic data on some protected and strictly protected plant species collected in Hungary between 2016 and 2021. The data published in this paper cover 31 micro regions of Hungary, but most of them come from the Great Hungarian Plain, especially from Pest and Bács-Kiskun counties. I describe the occurrences of 41 protected and three strictly protected vascular plant species (two ferns and 42 flowering plants), some of which represent new data for the particular micro region or even larger geographical areas (e.g. Botrychium matricariifolium, Thlaspi alliaceum and Nasturtium officinale). For some species, the published data either come from floristically understudied areas (e.g. Ranunculus illyricus, Vinca herbacea and Cardamine amara) or are considered rare in the certain region and/or in the whole country (e.g. Apium repens, Cnidium dubium and Vicia narbonensis). For other species, the newly reported occurrences are presented as complement to the already known distribution data (e.g. Cephalanthera damasonium, C. rubra, Linaria biebersteinii, Sonchus palustris and Agrostemma githago). In support of the nature conservation actions, I provide data from the flora of some floristically understudied micro regions (e.g. Dorozsma-Majsai Sand Ridge, Bácskai Loess Plain) and try to highlight the role of canals in Hungary in species and biodiversity conservation, by the example of the Danube-Tisza canal. In this manuscript, I publish data on twelve protected plant species from the Danube-Tisza canal and its canal bank (eg. Peucedanum palustre, Carex paniculata, Clematis integrifolia).

Historical occurrence of Spergularia echinosperma, a rare Nanocyperion species in Hungary
3–9Views:300Three species of the genus Spergularia have been known from Hungary. The most widespread one, Spergularia rubra (L.) J. Presl et C. Presl occurs on young sandy fallow fields and other disturbed habitats. The other species, S. marina (L.) Bess. and S. media (L.) C. Presl, occur sporadically in saline grasslands, and both have been recently spreading along salted roads. During a revision of the genus Spergularia in Hungarian herbaria, specimens of the species S. echinosperma (Čelak.) Asch. et Graebn. were found. It is a rare species previously known to occur only in Czechia and Germany and to be extinct in Austria and Slovakia (a few occurrences along the Morava and Danube rivers between 1909 and 1953). However, it was recently discovered in Western Siberia and Kazakhstan. It is a typical mudflat plant that occurs on exposed sandy shores of water bodies. Two herbarium sheets collected by Gyula Tauscher from near the village of Ercsi (riverbank of the Danube) in 1903 were found in the Carpato-Pannonicum collection of the Hungarian Natural History Museum. In addition, a new specimen was found, collected in Slovakia (Danube near Šamorín, collected by Mihály Résely in 1868) at the vicinity of the Hungarian border. The species was not confirmed during a field inspection of the target localities in Hungary; therefore, we have to consider it extinct in the country as well as in the whole Pannonian Basin. Recently, S. echinosperma was split into two subspecies – subsp. echinosperma and subsp. albensis. The subsp. echinosperma is probably restricted to fishponds in the SW part of Czechia and subsp. albensis occurs mainly in the floodplains of the river Elbe in Germany. The extinct populations of S. echinosperma in the Pannonian Basin belonged to the subsp. albensis. This taxon is morphologically close to S. rubra but can be reliably distinguished by densely verrucose seeds and shorter than wide stipules.

Contributions to the Atlas Florae Hungariae XIII.
85-88Views:58007The 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).

Contributions to the flora of Tolna and Baranya counties IV.
17-33Views:203The 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.

Contributions to the escaped, naturalised and potentially invasive species of the Hungarian adventive flora
111-156Views:609In this paper we compiled data on 157 Hungarian adventive plant species – of which 65 had not been reported from the country previously – from 47 settlements of Transdanubia and the Great Hungarian Plain. These taxa are rare, interesting or not included in the most recent list of the Hungarian neophyte species. The list includes data about many rare, occasionally escaping species (e.g. Lagurus ovatus, Salvia coccinea), taxa considered incapable of reproduction under the recent climatic conditions of the Pannonian Basin (e.g. Cupressus sempervirens, Punica granatum) or naturalised plants that may become invasive in the future (e.g. Celtis sinensis, Lonicera japonica). In the outlook we highlighted some special urban habitats (e.g. private and botanical gardens) and practices (e.g. public green space management) that endanger the native flora. We also describe their role in promoting the appearance and the expansion of alien plant species, and processes (e.g. laurophyllisation, spread of thermophile species) that will become increasingly common in the future as a result of climate change.

Interesting moss and liverwort records from the Western Mecsek Mts (South Transdanubia, Hungary)
29-38Views:107During an extensive field work in the acidophilous forests and fens of the Western Mecsek Mts. current localities of several species, which haven’t been recognised here for 50 years, were revealed (e.g. Bazzania trilobata, Diphyscium foliosum, Scapania nemorea). The authors also found some new stands of regionally and/or locally rare taxa (e.g. Buxbaumia aphylla, Dicranum tauricum, Jamesoniella autumnalis, Lepidozia reptans, Sphagnum squarrosum) as well as species new to the moss flora of the Mecsek Mts. (e.g. Aulacomnium androgynum, A. palustre, Calliergon cordifolium, Hedwigia stellata). Both investigated habitat types were found to be infected by invasive moss (Campylopus introflexus) and liverwort (Riccia rhenana) species. It is noteworthy that most of the species were found in winter or at the beginning of spring, when most vascular plants are inactive and their coverage is negligible. In this period moss and liverwort taxa are active, and are therefore easily noticeable. The authors raise the possibility that the expansion of Dicranum tauricum in Hungary is a consequence of former coniferous (especially Pinus spp.) plantations, since the old, dead trunks of pine species can serve as stepping stones to colonization for this taxon.

Additions to the flora of Jászság (Central Hungary)
21–30Views:327Within the framework of the Hungarian Flora Mapping Program, nine quadrants were surveyed in the territory of Jászság in 2012 and 2020. Regionally important floristic records of 68 vascular plant species are presented in this paper. Some of them are aliens (e.g., Alopecurus myosuroides, Amaranthus deflexus, Juncus tenuis, Phytolacca esculenta) or rare native weeds (e.g., Aegilops cylindrica, Bupleurum affine, Myagrum perfoliatum). Records of regionally (e.g., Coronopus squamatus, Linaria biebersteinii) or nationwide (Silene bupleuroides) rare native species as well as indicators of former forests (e.g., Clematis recta, Elymus caninus, Melica altissima, Sisymbrium strictissimum) are also presented. An interesting road edge rich in saline species (Artemisia santonicum, Chenopodium chenopodioides, Hordeum hystrix, Plantago maritima) is discussed in detail.

The biases of floristic surveys I. Naive planters: “cuckoo” of the Medves (N Hungary)
207-217Views:145The aim of the planned thematic studies is to point out the main biases and/or errors of floristic surveys in Hungary. In this first article of the series we focus on those examples when native species were planted out of their original habitats and/or range by a non-professional naturalist. The sources of information are those letters that were posted by Ferenc Varga to the first author of this article in 2005. The circumstances of the transplantation of 10 phytogeographycally significant species of the investigated area and/or the Pannonicum (Adonis vernalis, Arum orientale, Asarum europaeum, Genista germanica, Phragmites australis, Pulsatilla grandis, P. nigricans, Salvia aethiopis, Viola alba, Xeranthemum annuum) are detailed in the text and summarised in a table. The correspondence between the first author and Ferenc Varga provides insight how the ambition of a non-professional naturalist can influence the flora of an area. Most of the species were removed from South and transplanted to North, almost 10 km away from their original stands. With the exception of Adonis vernalis and Genista germanica at least one transplantation of the species was successful. In the case of Salvia aethiopis, the naturalized populations came 1.25 km close to Slovakia, where this species is a very rare and endangered (EN) taxon.

Notes to the vascular flora of Sopron Mountains and its foreground
187–194Views:338Records 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.

Contributions to the flora of the Szuha watershed and adjacent territories (NE Hungary)
27-67Views:320This paper presents new floristic data of 415 taxa from the Putnok Hills and Sajó Valley microregions (Northern Hungary). Records were collected between 1991 and 2021. In the first part new occurrences of legally protected (e.g., Cypripedium calceolus, Iris aphylla subsp. hungarica, Lycopodium clavatum, Thalictrum aquilegiifolium, Pyrola rotundifolia, Scorzonera purpurea, Stipa pulcherrima) and not protected but locally rare or data-deficient species (e.g., Myosurus minimus, Thalictrum simplex, Sisymbrium loeselii, Camelina microcarpa, Potentilla collina, Trifolium striatum, Geranium pratense, G. dissectum, G. divaricatum, Viola pumila, Epilobium roseum, Myriophyllum spicatum, Pimpinella major, Berula erecta, Trinia ramosissima, Centaurium pulchellum, Nepeta cataria, Limosella aquatica, Veronica scutellata, Orobanche arenaria, Utricularia vulgaris, Galium elongatum, Cephalaria transsylvanica, Dipsacus fullonum, Xanthium saccharatum, Alisma lanceolatum, Elodea canadensis, Potamogeton pectinatus, P. berchtoldii, P. lucens, P. nodosus, Zannichellia palustris, Sisyrinchium bermudiana, Melica picta, Elymus elongatus, Leersia oryzoides, Typha laxmannii, Eriochloa villosa) are presented. This chapter contains data on 246 species from which 8 are new for the flora of the Tornense flora region and 47 for its subregion, the Putnok Hills. Further contributions to the distribution data of Atlas Florae Hungariae are presented in Electronic Appendix. This section contains raw occurrence data of 169 species.

Taxiphyllum densifolium (Taxiphyllaceae) and other rare bryophytes of the Mecsek valleys (SW Hungary)
3-16Views:159In this paper, we deal with threatened and/or legally protected bryophytes found in the shady, forested valleys of the Mecsek Mountains, which are rare in national and/or local terms. Taxiphyllum densifolium, a rare moss in Europe has stable colonies with sporophytes in two valleys. This study is the first to describe the spore characteristics of this species. The previously considered unique and legally protected Rhynchostegiella teneriffae is nowadays so widespread in the Mecsek that it can no longer be considered a vulnerable species (VU) in Hungary. We present the first population of the legally protected Neckera pennata in Tolna county, and we also report on the recent, unusual occurrence of the data-deficient (DD) Fossombronia wondraczekii. We also list new populations of three other endangered (EN) species, Blindiadelphus recurvatus, Palustriella commutata and Porella arboris-vitae. Several vulnerable (VU) taxa such as Blepharostoma trichophyllum, Porella cordaeana, Sciuro-hypnum flotowianum, Seligeria pusilla, as well as new occurrences of near threatened (NT) mosses such as Microeurhynchium pumilum (with sporophytes), Phaeoceros carolinianus are documented. In addition, the data on Rhynchostegium rotundifolium in Jakab Mountain, which has not been recorded for more than 50 years, is confirmed. The difficulties of differentiating Hygroamblystegium species are briefly discussed.

Floristic records from Northern Hungary III. Zemplén Mts
109–172Views:479We report new floristic data collected from the Zemplén Mountains between 2004–2022. Altogether, 1215 occurrences of 133 species were recorded from 33 Central European Flora Mapping quadrats. We present occurrences of so far not reported or rare species, e.g., Carex appropinquata, C. cespitosa, C. disticha, Centaurea stenolepis, Scabiosa columbaria, Tephroseris aurantiaca. We put special emphasis on occurrence data of geobotanical importance, such as Anthriscus nitidus, Echium maculatum, Lunaria rediviva, Nepeta pannonica, Oreopteris limbosperma, Petasites albus, Primula elatior, Thlaspi jankae, Veronica montana, as well as newly rediscovered species based on archive data: Cirsium rivulare, Parnassia palustris. We mention common species, which are lacking data from the area, e.g., Adoxa moschatellina, Allium flavum, Cardamine amara, Dipsacus fullonum, Galanthus nivalis. Moreover, we report numerous new occurrences of taxa typical to the Zemplén Mts.: Aruncus dioicus, Huperzia selago, Lycopodium annotinum, Securigera elegans etc. We complete the enumeration with additional data from the literature and herbaria.

Contributions to the flora of railway-side pioneer habitats on Tiszántúl region
86–101Views:436Verges have considerable importance to preserve diversity in arable landscape. The modernized railway embankments are a great surface to the spread of native pioneer or adventive (invasive) plant species. The new data are about the flora of railway embankments mainly from Tiszántúl region. I present some species found on railway verges (e.g. Equisetum ×moorei, Equisetum ramosissimum, Lycopsis arvensis, Euphorbia maculata, Lepidium densiflorum Tragus racemosus, Vulpia myuros). An especially important new data is the refinding of Galium humifusum in Hungary. Locally non-native and adventive species can use the blanketing materials (sand or gravel) of railway embankments as dispersal corridor and colonize them. The railwayside habitats could contribute to the conservation of rare native pioneer species.

Rediscovery of Gymnadenia frivaldii Hampe ex Griseb. at its northern distribution limit (Eastern Carpathians, Romania)
213-220Views:200Frivald’s Gymnadenia is a very rare Balkan species in the South-Eastern Carpathians. The specific epithet “frivaldii” honours Imre Frivaldszky (1799–1870), a Hungarian naturalist. The species occurs in the drawdown zone of mountain fens of the Balkan Peninsula (Bulgaria, Romania, Greece, Macedonia, Montenegro, Albania), at elevations between 1000 and 2300 m. In the Carpathians the species was first reported from the Ţarcu Mts (Southern Carpathians) by János Heuffel. In 1874 Simonkai collected a specimen (BP 33967) in the Retezat Mts, but he was uncertain about its identity, thus this record eventually appeared as G. albida (Pseudorchis albida) in his monograph. Since then the species has been found at several localities in both the Retezat Mts (Mt Peleaga, Zănoaga, Zănoguţa, Ana and Bucura glacial lakes, Judele Valley) and the Ţarcu Mts. This paper reports on the discovery of Frivald’s Gymnadenia in the area of “Szökő-láp” (Harghita Mts, Eastern Carpathians), which can be considered a confirmation of the old literature record. This is the northernmost locality of this Balkan species known so far. The chorology and conservation status of G. frivaldii in the South-Eastern Carpathians are discussed.

New montane species in the Hungarian bryophyte flora
16-26Views:681During a bryofloristical investigation in the vicinity of Ómassa (Miskolc) in the Bükk Mountains (NE Hungary), three montane-boreal bryophyte species new to the Hungarian bryoflora were collected. Encalypta spathulata Müll.Hal. was found on the ledges of limestone cliffs of Vörös-kő Hill as well as on the rocky debris among roots of a fallen tree lying under the cliffs. Hydrogonium croceum (Brid.) Jan Kučera and Orthothecium rufescens (Dicks. ex Brid.) Schimp. were found in the crevices of dolomite cliffs on the north-facing steep slope of Jávor Hill. While the latter two species are widespread in European Mountains, E. spathulata is considered to be a rare species, and is assessed as ‘Vulnerable’ in the IUCN red list.

Floristic data from the Tokaj–Zemplén Mts and the surroundings (NE Hungary)
33–56Views:458In our paper, we publish the most important new floristic data from the region of Tokaj Hills and Zemplén Mountains (incl. Szerencsköz, Hernád-mente, Bodrogköz, Tatkaköz, Harangod) from the last ten years. During this period, we discovered two new protected species (Asplenium javorkaeanum, Epipactis nordeniorum) in the Zemplén Mountains and seven new protected species (Cephalanthera damasonium, Cirsium brachycephalum, Epilobium palustre, Epipactis palustris, Lycopodium clavatum, Pyrola rotundifolia, Polystichum aculeatum) in the Hungarian part of Bodrogköz. We found new locations of several rare species (Epipactis exilis, Dryopteris expansa, Blechnum spicant, Androsace maxima, Orchis coriophora, Orchis purpurea, Dactylorhiza sambucina, Sonchus palustris, Cicuta virosa). We confirmed the occurrence of four species, which have not been detected for decades (Sedum hispanicum, Erysimum wittmannii subsp. pallidiflorum, Pseudolysimachion spurium, Botrychium lunaria).

Data on the occurrence of sedge species (Carex, Cyperaceae) in and around South Nyírség (East Hungary)
165-198Views:423We provide floristic data on a total of 38 sedge species in the area of South Nyírség and its immediate surroundings. We also detected some populations of previously undescribed or rare species in the Hungarian Great Plain, such as Carex buxbaumii, Carex hartmanii, Carex umbrosa, and Carex paniculata. We report several new occurrences of species with little literature data from the area, such as Carex brizoides, Carex michelii, Carex pallescens, Carex elongata. However, during the last 13 years, we were not able to detect seven species previously mentioned in the literature. Herbarium data confirmed that some of the older Carex nigra occurrences for the area actually refer to Carex cespitosa. Based on herbarium data and the literature, we think that local data on Carex pairaei may largely refer to Carex divulsa subsp. leersii and/or Carex spicata. Contrary to many pieces of literature, Carex vulpina was not observed inside the sandy area.

Contributions to the Atlas Florae Hungariae VIII.
238-261Views:258The current paper is the 8th in the series aiming to contribute with new distribution data to the maps published quite recently in Atlas Florae Hungariae. Distribution data of 539 plant taxa from 157 flora mapping units is presented in this study, most of them are located in the western half of the country. As a result of systematic surveys, more than 190 new species were found in a single flora mapping quadrat. In another survey along some asphalted roadsides Puccinellia distans was found as a new species for 68 flora mapping grid units. All these indicate the necessity of further systematic research and publication of floristic results in papers like the “Contributions…” series. Most of the enumerated taxa are frequent, treated usually as weeds, but some of them are sparse and scattered or rare in Hungary (e.g. Nigella arvensis, Vaccaria hispanica, Rumex pulcher, Urtica urens), and in some cases they are legally protected plants in Hungary (e.g. Asplenium adiantum-nigrum, Dryopteris affinis, Gymnocarpium dryopteris and Huperzia selago). We also listed some casual alien plants and naturalized species that were not mentioned in the last neophyte list of Hungary (e.g. Acer cissifolium, Cyperus alternifolius, Gaillardia aristata, Galanthus elwesii). In the Outlook we pointed out the insufficient survey of some synanthropic (urban) habitat types in Hungary, like verges, gardens and flowerbeds that can be the hotbed of established species or can serve as stepping stones for potential invaders.

Some floristic data from surroundings of Kötcse II. (West Outer Somogy, South Transdanubia, Hungary)
114-121Views:113Floristic data of 73 species from NE part of West Outer Somogy are provided in the paper. Most of them were collected in 2016. The paper contains distribution data of species, which have not been detected in Outer Somogy so far (e.g. Peucedanum arenarium), and new occurrences of rare or sporadic taxa (e.g. Menyanthes trifoliata, Veronica scardica), as well as subspontaneous occurrences of cultivated species (e.g. Narcissus poëticus, Helleborus purpurascens) are provided.

Contributions to the flora of Baranya and Tolna counties III.
39-50Views:149During the last four years (2014–2017) that have passed since my last publication, I have been collecting 25 000 new floristic data for the territory of the Danube–Drava National Park. The most valuable and interesting records of 116 taxa are presented here, e.g. those of the strictly protected Digitalis ferruginea and Paeonia banatica, and the protected species Polystichum lonchitis, Dryopteris affinis, Doronicum orientale, Helleborus dumetorum, Corydalis intermedia, Spiraea media, Veratrum nigrum. New records of not protected but rare species, such as Lycopsis arvensis, Silene dichotoma, Teucrium botrys, Thladiantha dubia, Vicia lutea, Hypochoeris radicata are also enumerated. Some curiosities are mentioned as well, including the sizes of the biggest (and probably the oldest) Crataegus monogyna, Hedera helix, Ruscus hypoglossum and Ruscus aculeatus individuals that were found during my field work.

Mondró-halom kurgan (Hencida, East Hungary), a refugium of loess grassland vegetation
143-149Views:514Fragments of the natural grassland vegetation are often preserved only in those areas which are inadequate for arable farming. In many cases kurgans hold the last remnants of dry grasslands in lowland areas, like the Great Hungarian Plain. They also have an essential role in preserving cultural and landscape values. Moreover, they harbour several rare plant and animal species. Our aim was to explore the vegetation of the Mondró-halom kurgan (Hencida, East Hungary). Altogether we found 74 vascular plant species in the loess grassland of the kurgan. Several rare species of the Bihari-sík region, such as Inula germanica, Ranunculus illyricus and Rosa gallica were also detected. The steep slopes of the kurgan with various micro-sites and exposures supported a species-rich vegetation. Instead of its small area it harboured several forest steppic species and several steppic flora elements (Continental, Pontic-Mediterranean, Pontic, Pontic-Pannonic and Turanian).
