  This paper reports the second Hungarian synanthropic occurrence of the rare Myricaria germanica. One flowering individual was found in a gravel pit near Hejőpapi (NE Hungary). The closest known population of the species is 60 km far from newly found locality. This occurrence indicates effectivness of anemochory. It seems, that abandoned gravel pits may be potential habitats of this threataned shub species.

  Several studies found that waterfowl are important endozoochorous dispersal vectors for plant species. Germination of the seed content of their droppings provides valuable information on their diet and also on their role in seed dispersal. Our aim was to analyse the seed dispersal potential of the critically endangered habitat-specialist Lesser White-fronted Goose (Anser erythropus) in their autumn and spring staging areas in Hortobágy National Park. The study was supported by the LIFE10-NAT/GR/000638 project. We also studied the seed dispersal potential of larger generalist goose species foraging in the same areas, such as Greater White-Fronted Goose (Anser albifrons Scopoli) and Greylag Goose (Anser anser L.). We asked the following questions: (i) Which habitat types are the most frequently used by Lesser White-fronted Goose and larger goose species? (ii) Is the different habitat preference of Lesser White-fronted Goose and larger goose species reflected in the seed content of their droppings? (iii) Are there seasonal differences between the seed content of spring and autumn droppings? We identified the most frequently used feeding habitats. We collected 40 droppings of Lesser White-fronted Goose and larger goose species per site in April and October 2012, in total we collected 720 droppings per species. Droppings were concentrated and spread on trays filled with sterilised potting soil. Samples were germinated in a greenhouse from April to November 2013. In total we germinated 21 plant species from the goose droppings, which suggests that goose species play an important role in seed dispersal. We found that Lesser White-fronted Goose dispersed more species typical to alkali habitats, and fewer weeds compared to larger goose species. Lesser White-fronted Goose and larger goose species used a wide range of feeding habitats, thus, they play an important role in dispersing seeds between habitats along a moisture gradient. Total species number and species number of plant functional groups were higher in autumn droppings. Seed content of the droppings suggests that Lesser White-fronted Goose is confined to natural habitats, thus for the effective protection of this critically endangered species it is crucial to preserve its natural feeding habitats.

  In 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.

• The Sea milkwort (Glaux maritima) in the Carpathian Basin

  Sea milkwort (Glaux maritima L.) is a broadly distributed species in the northern hemi­sphere, inhabiting primarily maritime habitats from the arctic to the temperate zones. It is also found inland in semi-arid and arid regions with saline soils. Its status in the Carpathian Basin has become very uncertain owing to the lack of known extant populations. To evaluate its current status, I review all known occurrences within the Carpathian Basin where this species has been recorded or collected, and report five new localities of the species in Hungary, all in the western part of the Great Hungarian Plain. I also analyze habitat relationships of the species using traditional phytosociological relevés. Review of species distribution data in the Carpathian Basin revealed that sea milkwort has undergone severe reduction in population number and disappeared from many localities. Currently, only a few populations can be found in this region: the Northern Carpathians in Slovakia and the western part of the Great Plain in Hungary. In Transylvania (Romania), only a single population has been reported recently suggesting the critical status of the species there. Features of the habitats confirm the halophytic nature of the species and its fidelity to wet saline meadows. Its common accompanying species are mostly broadly distributed, salt-tolerant plants. Heterogeneity of the samples in species composition suggests that sea milkwort is not a habitat-specialist species. Several of its common associates in Hungary are also found in sea milkwort habitats in Mongolia, Asia and Utah, North America. Based on the available evidence, sea milkwort shall be considered a severely threatened plant in the Carpathian Basin. Characteristics of the vegetation in its habitats do not explain its occurrence in mountainous environments.

• Data to the distribution and nature conservation of Sorbus bakonyensis

  Sorbus bakonyensis (Jáv.) Jáv. (syn. S. majeri Barabits) is an apomictic species with a very narrow distribution range in the Bakony Mts (Hungary). Its previous occurrence data were published only from Kopasz Mt. (~Kápolna Hill, Csordás valley) above the village Márkó. It was possible to slightly expand the known area of the species to the East and to the West (Kis-Bükk Mt) of Kopasz Mt. with a detailed mapping. Due to the number of known individuals (six mature trees and a variable number of seedlings) and its small distribution range (~2 km²) the species is critically endangered. Regarding its small population, the high number of big game (wild boar, red deer) and the more and more frequent drought periods are significant risk factors. In situ preservation of the species is still a realistic goal, but ex situ propagation in tree nurseries and reintroduction to the suitable habitats of the mapped area (clearings, forest edges) are also justified.

  On 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).

  Three new localities of the protected and endangered moss species, Grimmia plagiopodia Hedw., were discovered in 2017 in the southern part of Börzsöny Mts (North Hungarian Mountains) at Nagymaros and Kismaros villages. The authors have re-evaluated the threat-status of the species applying the most recent IUCN Red List categories and criteria. According to this, G. plagiopodia can still get the endangered (EN) status in Hungary.

  Three new localities of the moss species Pseudoleskea saviana (De Not.) Latzel were discovered in the Börzsöny Mts in the administrative district of Perőcsény village, North Hungarian Mountains (Nagy-Hideg-hegy, near Hangyás-bérc, in the col between Csóványos and Magosfa). Small populations were found on shaded andesitic boulders in mixed deciduous forests. Up to the present, only old collections of the species were known from a single locality in the Mátra Mts; therefore, the red list status was data deficient. The morphological distinction of P. saviana from P. incurvata, its closely related congener also reported from Hungary is not always exempt from difficulties. However, the presence (P. saviana) or absence (P. incurvata) of a central strand in the stems, the shape of mid-leaf cells (P. saviana: more elongated, 3–4 times as long as wide; P. incurvata: at most twice as long as wide), as well as the shape of the outer basal cells (P. saviana: quadrate or shortly rectangular; P. incurvata: transversely elongated) seem to be reliable distinctive features.

  This is the first bryofloristic study in the Martonvásár manor park. In our survey in 2015, 56 species (6 liverworts and 50 mosses) were found in the park. Most of them are considered to be common in Hungary, but an endangered (Eurhynchium speciosum), a vulnerable (Orthotrichum patens) and five near-threatened species (Aphanorrhegma patens, Orthotrichum obtusifolium, Orthotrichum pumilum, Pseudocrossidium revolutum, Riccia cavernosa) were also found. These results point out the nature conservation value of the manor park.

  The 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.

  The distribution of fen pondweed (Potamogeton coloratus) restricted to Europe where it is one of the rarest and most threatened pondweed species. In Hungary, former data of fen pondweed originated mostly from thermal and karstic springs. Due to intensive bauxite mining activity in the edge of the Transdanubian Mountain Range (NW Hungary) these springs dried up by the end of the 20^th century, and it caused the temporal extinction of the species. After the ceasing of mining activity many of the former karstic springs have regenerated and several fen pondweed populations have re-established. In this paper we summarized 18 population data of fen pondweed collected between 1999 and 2016. Many of them were formerly registered in the 19^th century too. Most of the new and re-discovered populations were found in karstic springs or in artificial and natural lakes in the vicinity of these springs.

  Lesser 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).

  This study presents the current distribution of narrow small-reed (Calamagrostis stricta (Timm) Koeler) in the southern part of Nyírség (E Hungary). Beyond the efforts to confirm previously known occurrences, a high number of potential habitats were surveyed. Field work was carried out from late autumn to early spring taking advantage of the better perceptibility of dry foliage. The species was detected in 43 localities inside the boundary of 15 settlements, which considerably exceeded our expectations. Although most of the populations were quite small, in some cases their extent reached over 1000 m².  Populations around the settlements of Penészlek, Fülöp and Nyírábrány were the most frequent and the largest in size. The endangered status of the species is caused by the insufficient water supply of suitable habitats in the region. Besides habitat change, desiccation can also amplify the effect of anthropogenic disturbances (e.g. ploughing, fishpond development), which poses a further threat to populations.

  The present study reports the occurrence data of 54 vascular plant taxa, collected at various localities in Hungary during floristic, vegetation and ecological field surveys between 2000 and 2013. In some cases, phytosociological relevés were prepared to characterize the local coenological properties of the species. Many of these species are included in the „Red list of the vascular flora of Hungary” (e.g. Carthamus lanatus, Sedum caespitosum, Spiranthes spiralis and Trifolium micranthum). Some of them (e.g. Apium repens, Dianthus diutinus, Epipactis bugacensis and Ranunculus psilostachys) are rarities in the whole country. Our findings suggest that conservationists should focus not only on the maintenance of semi-natural habitats but also on the investigation of secondary habitats (e.g. river embankments, temporary pools on arable fields) in order to maintain the total species diversity of the landscape.

  Due to the geomorphological situation and climatic conditions of Hungary, true montane climate is restricted to very few and small areas of higher elevation, with the highest peak (Mt Kékes, 1014 m) in the Mátra Mountains (North Central Hungary). During a bryofloristical survey in this re­gion, a few cushions of a Boreo-arctic montane bryophyte species, Hymenoloma crispulum (Hedw.) Ochyra (syn.: Dicranoweisia crispula (Hedw.) Milde), was discovered at the steep northern slope of Mt. Kékes in an andesite boulder scree with cool and humid microclimate. H. crispulum is new to the Hun­garian bryoflora and fits in well with other co-occurring vascular and cryptogamic taxa of northern-montane affinities. The population is very small and vulnerable, therefore it should be rated 'critically endangered' (CR) in an updated national red list.

  This paper presents five new localities of the rare and threatened orchid Himantoglossum adriaticum in Zala county. The new localities falls within the known distribution area of the species. The population size on newly found locations are extremely small, in most cases only 1 generative individual were observed in the mesophilic secondary grasslands of abandoned vineyards. Highly possible, that this species shows a slow, but detectable expansion in Hungary, maybe due to recent climate change process.

  Dactylorhiza Necker ex Nevski is a complex genus. The taxonomy of these dactylorchids is widely considered to be complicated due to relatively high morphological variability within species and high frequency of hybridization between species. During a floristic survey of the Valea Morii (Morii Valley, Malomvölgy) Nature Reserve in June 2017, a population of Dactylorhiza traunsteineri (Saut. ex. Rchb.) Soó, a species with uncertain presence in the Romanian flora was found. In the Morii Valley, this narrow-leaved marsh-orchid was encountered in fen-patches, in phytocoenoses of the plant association Orchido-Schoenetum nigricantis Oberd. 1957. Due to the cool and wet microclimate of the Morii Valley, many glacial relicts and other plant rarities (e.g. Tofieldia calyculata (L.) Wahlenb., Swertia perennis (L.), Liparis loeselii (L.) Rich., Ophioglossum vulgatum L. Schoenus nigricans L.) had been able to survive on strongly humid places on calcareous soils. This study reports the first occurrence of D. traunsteineri in Romania confirming the presence of a highly debated taxon. We also discuss the morphological features, habitat preference and conservation status of this new species in the Romanian Flora.

  In this paper, we report a new occurrence of Myricaria germanica (L.) Desf in a secondary habitat from the north-eastern part of Hungary, from the edge of the Bükk Mountains, in a slag dump in Miskolc. The plant is established on a steep wall formed during the extraction of slag. Due to the erosion of the wall, occasionally a few plants fall off. The age of the dead specimens is between 5 and 13 years, based on their growth rings. The population of about 50 individuals is the largest (but perhaps the only) living population of the species in Hungary. Other rare and protected species (Epilobium dodonaei Vill., Dysphania botrys (L.) Mosyakin & Clemants, Dryopteris carthusiana (Vill.) H.P. Fuchs, Polystichum aculeatum (L.) Roth ex Mert.) have also been found in the slag heap area.

  The 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.
