Floristic data from the northern edge of the floristic region ‘Crisicum’ (NE Hungary) II.: Borsodi-ártér és Sajó–Hernád-sík
169–186Views:343In this paper we provide new floristic data for 126 species and one hybrid from the Borsod Plain and the Sajó–Hernád Interfluve (Borsod-Abaúj-Zemplén county, Northeast Hungary) observed between 2006 and 2019. A significant proportion of the data is related to gravel mining activities in the area. We present new localities for rare or sporadic native taxa in Hungary (e.g. Chenopodium murale, Ch. rubrum, Lycopsis arvensis, Chamaenerion dodonaei, Reseda luteola, Senecio viscosus, Gnaphalium luteoalbum, Cyperus glomeratus) as well as rare or sporadic adventive weeds (e.g. Lepidium densiflorum, L. virginicum). We publish additions to the distribution of several legally protected species (e.g. Pseudolysimachion longifolium, Nymphoides peltata, Epipactis tallosii, Leucanthemella serotina). Presence of some taxa is remarkable regarding to the flora of the whole area of Crisicum (Sherardia arvensis, Thymelaea passerina, Silene conica) or the Great Hungarian Plain (Monotropa hypopitys).

Floristic data from the Tokaj–Zemplén Mts and the surroundings (NE Hungary)
33–56Views:375In 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).

New occurrences of Ranunculus strigulosus in East Hungary
3–8Views:310The exact distribution of Ranunculus strigulosus Schur is poorly known in Hungary. Current occurrence data of the species mainly from Békés county and only one archive data from the Nyírség region, from the 1920s were known. This study presents eleven newly discovered occurrences in East Hungary. Populations were found in wet meadows, forest glades and poplar plantations. Nine of these populations are located at the southeastern edge of the Nyírség region and most of them are quite small. Three larger population were found in Nyírábrány, Álmosd and the Tócó Valley between Debrecen and Hajdúböszörmény. One of the newly discovered populations provides a new contribution to the flora of Bátorliget Marsh and Fen-wood NCA. Some morphological characters (hairs on the stem and the leaves, shape of the leaves developed before and after the mowing) are also discussed.

Distribution of Campylopus introflexus (Hedw.) Brid. in Hungary
212-219Views:62Based on field work data collected in 2013–2014, the authors generated a map of the current distribution of Campylopus introflexus for Hungary. Besides the coordinates and geographic name of the localities, an estimated size of the population, the type of habitat and substrate, the co-occurring moss species and affected vegetation types were also recorded. Altogether, 18 stands were found in 8 geographical regions of Hungary, in some cases Campylopus introflexus was found to be a new species record for the moss flora of the respective region (e.g. Dunántúli-dombság, Nyugatmagyarországi peremvidék). In addition to the pine plantations from where it was detected formerly, the mixed deciduous-coniferous forests, the acidophilous oak woodlands and man-made habitats were found to be also proper habitats for this moss taxon. Earlier data mainly originated from pine deadwood, the recently discovered stands were found on acidic soil surfaces. The most important cooccurring moss species were the followings: Hypnum cupressiforme, Polytrichum piliferum, P. formosum, Pohlia nutans and Ceratodon purpureus. Campylopus introflexus had prominently high coverage in the acidophilous oak forests of the Mecsek Mts, where it occurs on acidic sandstone covered with a thin debris of the bedrock. This neophyte moss is widely distributed in Hungary, and has stable populations. Further expansion is expected in the subatlantic and submountain regions of the country, and in regions characterised by acidic soils and pine plantations.

Contributions to the Atlas Florae Hungariae VIII.
238-261Views:196The 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.

Recent Hungarian distribution of Potamogeton coloratus
77–83Views:135The 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 20th 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 19th 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.

Distribution of Pseudoleskea saviana (De Not.) Latzel in Hungary
272–285Views:122Three 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.

Occurrence and habitat conditions of Gagea minima along the Sorok stream (W Hungary)
189–194Views:108Gagea 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.

Rare vascular plants and fungi of Zalaegerszeg-Botfa (W Hungary)
95-103Views:182The present study reports the occurrence data of 3 macrofungi and 47 vascular plant taxa, collected in Zalaegerszeg-Botfa between 2006 and 2017. These new data provide valuable additional information to the distribution map of the studied species. The spatial and abundance information of both protected and non-protected species can contribute to the future biodiversity monitoring activities in order to asses and mitigate the human impact upon natural plant communities and semi-natural habitats.

Orchids of poplar plantations – a review
102–117Views:726099There are literature data on the occurrence of 26 orchid species and 2 hybrids in economic poplar plantations from 13 European countries. The occurrence of 4 additional species in poplar plantations in 3 countries is proved by sources on the World Wide Web. The most widespread orchids in the poplar plantations are the rhizomatous, partial myco-heterotroph Cephalanthera and Epipactis species. Their importance is enhanced by the fact that most of the known populations of some species with a relatively narrow distribution range (Epipactis bugacensis, E. campeadorii, E. fibri, E. tallosii, E. zaupolensis) are known in poplar plantations. Cultivated poplar monocultures are likely to provide habitat for further orchids in other countries too. Most of the published papers are limited to floristic data from a single or a few plantations. Longer-term observations are only available from Poland, thanks to the work of W. Adamowski, and these suggest that populations may persist for decades and even increase dynamically. The size of orchid populations in some cases can reach thousands or even hundreds of thousands of individuals. Orchids can appear earliest in (4–)7–8 years old plantations. Very little is known about how the cultivation, structure, soil conditions and the poplar cultivars influence the presence of orchids. Mycorrhizal interactions of poplars and orchids may play a key role in this process, but the available knowledge is very limited. Furthermore, little is known about how the economic use of plantations can be reconciled with the long-term maintenance of orchid populations.

The Sea milkwort (Glaux maritima) in the Carpathian Basin
10-20Views:289Sea 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.

Floristic records from Northern Hungary III. Zemplén Mts
109–172Views:374We 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.

Data to the flora and geobotany of Kisalföld (Lesser Plain) region, NW Hungary
235-253Views:112Lesser 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).

Contributions to the knowledge of biology and Hungarian distribution range of Orobanche reticulata
95-98Views:380Some new Hungarian occurrences of Orobanche reticulata Wallr. are discussed in this paper. On the Bér-hegy hill (Eastern Bakony Mts) the species was observed on a so far unknown host plant (Carduus hamulosus). Although the species usually flowers from May to July in Hungary, the observed individual was in full bloom in October, probably due to the extremely rainy year (2010). Another population of the species, found at Magyaralmás settlement in the foreground of the Vértes Hills, deserves attention because of its size. In early summer of 2020, individuals of O. reticulata appeared in a great quantity (several hundred ones) on a fallow land that was developed from a natural dry grassland having been ploughed in the previous year. In this case the local host plants were Carduus nutans subsp. leiophyllus and Carduus acanthoides. Some further records of the species from the Transdanubian Mts and the regions of Külső-Somogy and Mezőföld present new data in the Hungarian flora mapping program.

The microscopic fungi of protected plant species in the Őrség National Park and the surrounding area (W Hungary)
187-211Views:45The paper deals with the study of microscopic fungi occurring on protected plant species of the National Park of Őrség and the surroundings. The survey includes both field observations and laboratory tests. The aim of the study was to identify the microscopic pathogen fungi living on protected plant species. Also spatial and temporal distribution, infection and damage rate of pathogenic fungi infections were determined for some protected plant species. Between 2002 and 2009 mycological research was conducted including 78 protected plant species and near to one hundred fungus species were identified on them. We provided data at the first time of microscopic fungi found on protected plants of Őrség.

Fern (Pteridopsida) flora of South Nyírség (East Hungary)
162–182Views:342The study presents a number of new data on the fern flora of South Nyírség, and reviews all available literature and herbarium fern records from the area. A total of 19 Pteridopsida species were detected in the region. The hart's tongue fern (Asplenium scolopendrium) and the soft shield fern (Polystichum setiferum) were hitherto unknown in the whole Nyírség region (flora district “Nyírségense”). The broad buckler-fern (Dryopteris dilatata), scaly male fern (Dryopteris affinis) and floating fern (Salvinia natans) are new records to the area of South Nyírség. Dryopteris dilatata has been found in a surprisingly great number of localities. Some morphological characters facilitating identification of this species are also discussed. The local pine plantations, fens, carrs and humid deciduous forests are important habitats for ferns. In some localities the co-occurrence of 5-6 fern species were observed. The increasing aridity in the last decade is posing a serious threat to ferns in the area.
