Ceratocephala testiculata (Crantz) Roth and further data to the flora of the foothills of Bükk Mts.('Bükkalja', NE Hungary)
81-142Views:336This 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.

Spreading along the railways: morphology and invasion success of Vulpia ciliata in Hungary
145–156Views:852Vulpia ciliata Dumort, a widespread species in the Mediterranean region, has been introduced in several European countries in recent decades, mainly along railways. The species was first discovered in Hungary at Szolnok railway station in May 2016, then a few days later at Keleti railway station in Budapest. In 2020 the species was found in several Transdanubian railway stations. Apparently, V. ciliata has recently been established in numerous parts of the country, probably spreading by railway transport. Until now, the species has only been found in the vicinity of regularly used tracks (in a distance of 20 m at the most). Being an invasive alien species, V. ciliata can displace the native Vulpia myuros in ruderal vegetation along railway lines. The species can easily be distinguished from V. myuros by its hairy lemma. Moreover, it flowers earlier than the other two indigenous species in Hungary, often already in late April. Based on the characteristics examined (number of nodes in the upper 2 cm zone of the rachis, number of fruits per spikelet, rate of fertile and sterile florets within the spikelet, lower and upper glume length, lemma and awn length separately, rachis width in the upper 2 cm zone) we have concluded that V. bromoides and V. myuros are less different from each other than V. ciliata from these two species. In the case of V. ciliata subsp. ciliata, we observed that spikelets (detached from the inflorescens) function as dispersal units. Therefore we assume that the observed low fertility rate within the spikelets, as well as the presence of marginal cilia on lemmas promote the spreading success of V. ciliata (spreading in clusters, anemochory, zoochory, anthropochory). Its early maturation (in May) can also facilitate its spread along railways, because the populations survive the chemical weed control usually carried out in late spring. The other two Hungarian species usually ripen later (in June). For the time being, the spread of V. ciliata outside the Hungarian railway network may be hindered by climatic conditions, or by the lack of seasonal weed control outside that network, which otherwise offers a relative survival advantage for V. ciliata along railway tracks.

Three new grass species to the alien flora of Hungary: Paspalum dilatatum, Phalaris aquatica and Panicum schinzii
63–76Views:453In this paper, we present the new occurrence of two grass species previously unknown in the flora of Hungary and one grass species for which we have only one historical record. Panicum schinzii Hack. is an annual species from South Africa, Paspalum dilatatum Poir. is a perennial species originating from South America, and Phalaris aquatica L. is also a perennial taxon native to the Mediterranean. The only well-developed individual of Panicum schinzii was found on a gravel reef of the Rába river in Western Hungary, while the two newly observed perennial grass species appeared in the Great Hungarian Plain: a single individual of Paspalum dilatatum was observed in a suburban environment on the southern edge of the town of Soltvadkert, while a small population of Phalaris aquatica occurs along a highway near Szeged. In this paper, we describe the European distribution and habitat preference of these three species, we assess their invasion potential and we fit them into the Hungarian dichotomous key of vascular plants. Although we cannot state with certainty that the specimens of Panicum schinzii, Paspalum dilatatum and Phalaris aquatica we report here are the first ones that have ever appeared in Hungary, but their localities and the numbers of individuals suggest that they have entered the country very recently. The annual Panicum schinzii certainly arrived to Hungary naturally by the river Rába, while the perennial Paspalum dilatatum and Phalaris aquatica are more likely to have been introduced by human activities, but both inadvertently. Paspalum dilatatum arrived to its site near Soltvadkert by accident, in the form of propagules in some intentionally sown seed mixture. The fact that all three species are considered in some countries to be invasive or at least problematic species is a cause for concern.

Chorological notes on the vascular flora of Hungary
85-119Views:484The 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.

Taxonomic revision of alien Ludwigia species in Hungary
153–164Views:501Some tropical Ludwigia species have been planted as ornamentals in Hungarian thermal springs since the 1920s. Although they have become naturalised or even invasive in a few places, their specific identity remained generally uncertain. Our herbarium and field studies revealed that three species of alien water-primroses occur in Hungary. The most frequently planted one is Ludwigia repens, which is, however, a sporadic species in its native distribution area. We have found this species in several parts of the country. Although a few escaped and self-sustaining populations were also observed, this species has appeared to be non-invasive so far. Ludwigia grandiflora appeared in Hungary at the beginning of the 2000s. At the moment it is known from three localities, though spreading rapidly, becoming already invasive in its locality at Tata city. A similar species, L. peploides has recently been reported from two localities, where it forms small stands; the success of its naturalisation can be assessed in the future. We found no evidence for the Hungarian occurrence of L. alterniflora that had been published from Eger city. Therefore we suggest deleting this species from the current Hungarian checklist.

The purple viper's bugloss (Echium plantagineum), a new adventive species for Hungary
199-206Views:1173Following global trends, the number of newly established alien plant species is increasing in Hungary. Not only professional scientists but also citizens could contribute to the discovery and documentation of new occurrences. One of the first records of the purple viper’s bugloss (Echium plantagineum L.) in Hungary originate from an online group dealing with wild plant species identification. This species is native in Western Mediterranean countries, and is introduced to other continents. In Australia, it is a well-spread, largely problematic invasive species, and it might show similar tendencies in Hungary as well. In order to acquaint the wider public with this species, we present its morphology, phenology and other characteristics and provide a possible inlay in the Hungarian identification key.

Contributions to the Atlas Florae Hungariae XIII.
85-88Views:58315The 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).

Spreading of native Spergularia species along roadsides of Transdanubia (NW Hungary)
141-150Views:397During the systematic floristic research along Transdanubian roads (NW Hungary) since 2013, two native halophyte Spergularia species has been found. Due to the well known spreading near motorways in Eastern-Central Europe, the appearance of Spergularia marina along roads in north-western Hungary is not a surprise. Occurrences of the species were registered along fourteen main roads. Some of the stands are very rich where S. marina forms single-species lines along the asphalt edge. The spreading of Spergularia media along roads is yet much less intensive. Four stands were found near the motorways M1 and M7, main road 74, and the common section of the main road 86-87. Both species are native in the Hungarian plains, being specific elements of Pannonic alkali grassland associations, however, their secondary migration along road edges is promoted by road salting, intensive management of roads and increased vehicle traffic. In this paper, we specify secondary occurrences of the two Spergularia species, discuss their ecological and abiotic circumstances and publish corresponding distribution maps. Due to recognition problems in Spergularia, a corrected determination key was provided.

The biases of floristic surveys I. Naive planters: “cuckoo” of the Medves (N Hungary)
207-217Views:258The 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.

Asparagus verticillatus L. in Hungary
38-43Views:323Climbing asparagus (Asparagus verticillatus L.) a new adventive species to the Hungarian flora was recently discovered in the city of Pécs (South Hungary) in 2011–2012. Taxonomy, morphological description and current localities of the species are presented in this paper. A. verticillatus is a mediterranean-submediterranean species native in Balkan Peninsula, Eastern Europe, Western- and Middle Asia. The species is a popular ornamental plant in Hungary, but no data was available about its escape or naturalisation in the country so far. Herbarium specimens from Hungary were collected so far mostly from botanical and private gardens; only one specimen was collected in a dry grassland along a roadside in the city, respectively. The newly discovered small populations are located mostly in secondary dry grasslands, at the edges of vineyards and private gardens on the southern slopes of the Mecsek Mts and only one specimen was found far from the residential area in natural vegetation. Because climbing asparagus is a frequently planted ornamental plant in several locations of Pécs, further escape, naturalisation and persistence of the species is possible in the future.

Contributions to the escaped, naturalised and potentially invasive species of the Hungarian adventive flora
111-156Views:899In 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.

Contributions to the flora of Western-Transdanubia (W Hungary)
213-234Views:295In this paper, we presented the results of our floristic survey in West-Hungarian region. The data were collected between 2005 and 2015 and supportted with herbaria or photo-documentation. This paper reports new floristic data of 98 taxa from West-Hungary with altogether 172 field-collected data records. In the survey we focused on little-known taxa with a phyto-geographic importance. For some taxa we checked the herbarium specimens of Savaria Museum and Natural History Museum of Budapest. During our fieldwork we recorded 8 species new to W-Hungary, including 3 species considered to be native to the region [Oenanthe banatica Heuff., Koeleria pyramidata (Lam.) P. Beauv., Polycnemum majus A. Braun.]. Almost all of the recorded species are regarded as indigenous plants, many of them has nature conservation importance, thus, their monitoring are highly advised. We found new localities of many species which of high importance for plant geography describing their current distribution. Most of the recorded species occur in natural or semi-natural habitats, but some taxa were found in synanthropic habitats and extensive arable lands.

Additions to the flora of Jászság (Central Hungary)
21–30Views:472Within 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.

Data on the native vascular plant species of the Pannonian Region II. (6–22)
233–252Views:380In the second part of this article series, which provides data contributing to the knowledge of native plant species of the Pannonian Ecoregion, we address rare species – mostly legally protected in Hungary – belonging to the families Cephaloziaceae, Athyriaceae, Dryopteridaceae, Cystopteridaceae, Thelypteridaceae, Brassicaceae, Rosaceae, Elatinaceae, Apiaceae, Orobanchaceae, Liliaceae, and Orchidaceae. We report the current occurrence of Nowellia curvifolia in the Sub-Pannonian region of Slovenia. We present an exceptionally species-rich habitat for ferns (Athyrium filix-femina, Dryopteris carthusiana, D. dilatata, D. filix-mas, Gymnocarpium dryopteris, Polystichum aculeatum) from the ‘Borsodi ártér’ microregion. We provide data on the stands of Thelypteris palustris observed along the main irrigation canals of ‘Tiszántúl’ region. We publish new occurrence records contributing to the Hungarian distribution of Aethionema saxatile, Crataegus nigra, Elatine hungarica, Sium sisarum, Orobanche hederae, Himantoglossum adriaticum, Epipactis placentina, E. exilis, E. pseudopurpurata, and E. microphylla, as well as to the appearance of Helosciadium repens in urbanized environment. Gagea spathacea and G. bohemica are newly recorded for the Zemplén Mts; Epipactis nordeniorum and Epipogium aphyllum are new for the flora of the Mátra Mts; and Himantoglossum calcaratum is newly recorded for Hungary. We also present spontaneous establishment of several orchid species in the courtyard of a secondary school in Veszprém. Additionally, we report on the pollinating insects observed on the flowers of Sternbergia colchiciflora. Two previously misreported records are also corrected.

Contributions to the flora of railway-side pioneer habitats on Tiszántúl region
86–101Views:537Verges 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.

Contributions to the Atlas Florae Hungariae X.
101–106Views:605This paper is the 10th in the series aiming to contribute with new distribution data to the maps published recently in Atlas Florae Hungariae. Distribution data of 686 plant species from 194 flora mapping units are published in this study, but all of them are listed in an electronic appendix. As a result of local surveys, more than 100 new species were found in a single flora mapping unit. Other “linear surveys” along the National Blue Trail revealed 142 new species in 10 flora mapping units in total. Among these, Carex strigosa is one of the most interesting taxa in the Bakony Mts. Previously published and new distribution data of this legally protected sedge species suggests that it is spreading from SW to NE within the Transdanubian Mts. Results from our survey shows that studying synanthropic habitats like frequently used hiking trails might provide a significant amount of new data points at the scale of Hungarian Flora mapping units. Moreover, similar studies might shed some light on the origins and migration routes (e.g. Illyrian and Dacian routes) of “native” species.

New data on the Hungarian adventive flora: Acer opalus Mill. subsp. obtusatum (Waldst. et Kit. ex Willd.) Gams 1925 in Hungary
229-238Views:139Acer opalus Miller 1768 because of its complex taxonomic status can be interpreted as a collective species which contains several species and subspecies depending on different interpretations. An important adventive occurrence from this collective species was found in a forest that belongs to the Tétényi plateau (Budapest, 11th district) in July of 2009. It is proved to be Acer opalus Mill. subsp. obtusatum (Waldst. et Kit. ex Wild.) Gams. The natural range of the subspecies covers the eastern side of the central Mediterranean Sea region and western Balkan Peninsula. It is a submediterranean-mediterranean, thermophile, shade-tolerant taxon but often appears together lightdemanding species too. In its native range it occurs in beech, pine, sessile oak forests and in different types of dry oak forests as admixed tree species. The subspecies was found in a turkey oak – sessile oak community in Hungary. Several old, seed growing individuals live on the spot which have had continuous seed production. Therefore from the old trees to the young seedlings different age categories are represented.

The historical occurrence of Digitaria ciliaris in Hungary – results of a herbarium survey
53–62Views:347Revision of genus Digitaria in BP Herbarium Carpato-Pannonicum collection helped to discover the historical occurrence of Digitaria ciliaris (Retz.) Koeler from Győr, in the area of an old cotton and wool processing and textile factory. However, it has been proved that the previously published Hungarian records of the species are all wrong, as the Digitaria-keys of Hungarian herbals misinterpreted the taxon, mainly as a synonym of D. sanguinalis subsp. pectiniformis. The herbarium survey confirmed that D. sanguinalis is the most common taxon in Hungary. D. sanguinalis subsp. pectiniformis is also widespread, but probably somewhat under-mapped. Probably not native to Hungary, most probably an archeophyte taxon. Specimens have been collected from disturbed habitats associated to railways and from xerothermic vineyard areas for over a hundred years. D. ischaemum is certainly native to the region, with a recognisable natural distribution pattern, and is found mainly in the sandy and gravelly soils of the lowland and hilly areas of the country. This species has recently become more common in urban areas across the country with the recent spread of sand-lined pavements. D. ciliaris of tropical/subtropical origin is a casual alien species that was formerly present in the Hungarian flora.

Occurrence and habitat conditions of Gagea minima along the Sorok stream (W Hungary)
189–194Views:338Gagea minima (L.) Ker Gawl. is a Eurasian bulbous species. It occurs sporadically in Hungary, but so far only one current occurrence is known from the Western Transdanubia. In recent years, a large metapopulation has been found in a 15 km long section of the Sorok stream. Its habitat is the high sandy bank above the stream, where it lives mostly in nitrophilous vegetation under non-native tree species. Its long-term persistence in this secondary habitat may have been facilitated by its bulbs, which may have been regularly dispersed by periodic disturbance. Myrmecochory may also have played a role in the local establishment of subpopulations. A number of recently found populations indicate that data on the distribution of the species is still incomplete. The lack of data is probably due to its short flowering period and relative inconspicuousness. Gagea minima is considered a valuable relict species in the altered environment of the Sorok stream and its surroundings.

Rubus armeniacus Focke, an unnoticed invader in the Hungarian flora
220-228Views:215The authors report on the occurrence, distribution and invasion potential of Rubus armeniacus, a bramble species of Caucasian origin, in Hungary. The first verified records of the species are from the 1990s. It has established strong populations in ruderal habitats mainly around Budapest and some other cities, whereas its competiveness is rather weak in closed non-lowland forests rich in native bramble species. In terms of conservation, it constitutes a real threat to the vegetation of Pannonian sandy habitats. The results of this study also emphasize the importance of recognising "nonnative cryptic species" for ecology and conservation biology.

Escaping of Euphorbia myrsinites from cultivation in Eger (E Hungary)
253–256Views:250Euphorbia myrsinites L. (Euphorbiaceae) is a well-known ornamental plant with native distribution around the Mediterranean Basin, the Black Sea, the Caucasus region and Minor Asia. Its escape from cultivation and its naturalization in Western and Central Europe as well as in North America was reported in many cases. In Hungary, the casual escape of E. myrsinites has been documented more than fifty years ago and new observations were recently reported from different regions of the country. Here, I discuss a new record of the species from the town of Eger (E Hungary). The obtained data allow considering E. myrsinites as a locally naturalized species in the flora of Hungary. According to standardized criteria, the species may be able for local invasions too, but further observations are needed to accurately determine its present status in Hungary.

Astragalus vesicarius and other new taxa to the flora of the Vértes Mountains (Hungary, Transdanubian Mts)
195–199Views:424A 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.

Contributions to the flora of the Szuha watershed and adjacent territories (NE Hungary) II.
41–52Views:347This 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. We also recorded native and archeophyte weeds (Salsola kali, Silene dichotoma, Ranunculus arvensis, Bunias orientalis, Diplotaxis muralis, Vicia pannonica, Euphorbia exigua, E. falcata, Androsace elongata, Ajuga chamaepitys, Sherardia arvensis, Bromus secalinus), spreading aliens (Phytolacca americana, Mahonia aquifolium, Oxalis dilleniid, Abutilon theophrasti, Asclepias syriaca, Juncus tenuis, Elymus elongatus, Panicum dichotomiflorum) and escapees (Aquilegia vulgaris, Trifolium incarnatum, Foeniculum vulgare, Primula vulgaris, Lonicera caprifolium). This article contains data on 144 species, 8 of which are new to the flora of the Tornense region (Phytolacca americana, Mespilus germanica, Rhinanthus ×hungaricus, Orobanche alba subsp. major, Dipsacus ×fallax, Filago vulgaris s. str., Rudbeckia hirta, Bolboschoenus laticarpus) and 8 to the Putnok Hills (Polystichum aculeatum, Ranunculus trichophyllus, Diplotaxis muralis, Lathyrus palustris, Lonicera caprifolium, Crepis pulchra, Allium rotundum, Lolium multiflorum).

Contributions to the Atlas Florae Hungariae IX.
253–256Views:564The current paper is the 9th in the series aiming to provide new data to the distribution maps of Atlas Florae Hungariae. Data of 734 vascular plant taxa (from 222 flora mapping quadrats) are presented in this study. The new localities are spread across nearly the entire country; however, most of the data are from the North Hungarian Mts, the northern part of the Danube-Tisza Interfluve, the southern edge of Hanság, alongside River Maros and the Hortobágy. Altogether, 1632 new data records are presented in this paper. The list mainly contains rare and locally important native species, as well as species with uncertain native/alien status (e.g. Allium ursinum, Chamaecytisus triflorus, Cotoneaster niger, Cyperus pannonicus, Elatine triandra, Eleocharis acicularis, Eleocharis ovata, Erodium hoefftianum, Geranium lucidum, Globularia punctata, Hippuris vulgaris, Hottonia palustris, Lindernia procumbens, Marrubium vulgare, Ononis pusilla, Orobanche bartlingii, Orobanche cernua, Pisum elatius, Polycnemum majus, Polygonum graminifolium, Ribes nigrum, Schoenoplectus triqueter, Verbascum ×denudatum, Verbascum ×vidavense, Viola canina subsp. schultzii). We report new localities of expanding alien species (e.g. Amaranthus deflexus, Artemisia annua, Euphorbia maculata, Helminthia echioides, Hordeum jubatum, Impatiens glandulifera, Ipomoea purpurea, Mahonia aquifolium, Panicum riparium, Robinia viscosa, Rudbeckia hirta, Veronica peregrina, Yucca filamentosa) and mention a few rare, successfully “surviving” alien plants with nature conservation value (e.g. Acorus calamus, Monochoria korsakowii). Moreover, occurrences of common plants are presented when new to the Atlas Floraea Hungariae (e.g. Bromus hordeaceus, Symphytum officinale, Vicia tetrasperma).

Floristic records from northern Pest and western Nógrád counties
193–202Views:165This paper presents significant floristic records from recent years in the northern part of Pest County and the western part of Nógrád County. The 100 occurrences represent 54 species, of which three are pteridophytes and 51 are flowering plants. The occurrences are new at least at the microregional level or, in some cases, confirm old or uncertain records. Fifteen species are newly recorded or have significant new data for the North Hungarian Mountains. Most of the species are aliens or native plants showing secondary spread along roads. For several of them, a northward expansion of their distribution in Hungary has been identified.
