  In 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).

  The paper gives new floristic data from several regions of Hungary. Some of them are recent evidences of old data (e.g. Herniaria incana in Pomáz), others are new occurrences of recently expanding alien species (e.g. Eleusine indica, Geranium purpureum, Typha laxmannii), casual species (e.g. Lobularia maritima, Nepeta racemosa) or legally protected taxa (e.g. Agrostemma githago, Ornithogalum brevistylum, Ranunculus illyricus, Sonchus palustris).

  This paper reports new floristic data of 161 taxa. Most of these data were collected between 2011–2013, and are coming from the northern edge of the floristic region 'Crisicum', the NE part of the Great Hungarian Plain, which is a little-known area from a floristic point of view. 43 CEU quarterquadrates and territory of 35 settlements are represented by the dataset. The paper reports occurrence localities for legally protected (e.g. Ophioglossum vulgatum, Stellaria palustris, Ranunculus polyphyllus, Thlaspi jankae, Lathyrus palustris, Elatine spp., Lycopsis arvensis, Lindernia procumbens, Cirsium brachycephalum, Cyperus pannonicus), strictly protected (Armoracia macrocarpa, Vicia biennis) and some little-known (e.g. Cardamine parviflora, Reseda luteola, Melilorus dentatus, Veronica catenata) taxa. Numerous data of alien species (e.g. Lepidium densiflorum, Euphorbia maculata, Sicyos angulatus, Erechtites hieracifolia, Elodea nuttallii, Elymus elongatus, Eleusine indica, Sorghum halepense, Eriochloa villosa) are also published. The most important data are documented by voucher specimens deposited in herbarium of Debrecen University (DE).

  During 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.

  The 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.

  The 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.

  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.

  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 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.

  In 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).

  We report the occurrence data of 44 vascular plant taxa collected at various localities in Hungary (mainly the Danube–Tisza Interfluve and South Transdanubia) during floristic, vegetation and ecological field surveys between 2016 and 2018. Of the species in the present article, 27 are protected or strictly protected. In the paper we focused on plants that are rare regionally (e.g. Botrychium lunaria, Polystichum aculeatum) or in the whole country (e.g. Ophrys oestrifera, Ranunculus psilostachys), as well as on plants that occurred in unusual habitats (e.g. Corydalis solida). We also included new localities of weedy species, some of which (e.g. Opuntia humifusa, Sporobolus cryptandrus) may present nature conservation threats.

  In this paper a review of the nomenclature, etymology, taxonomy, morphology, histology, life cycle, phenology, reproduction, habitat preference, biotic interactions, biologically active compounds, micropropagation, application possibilities and conservation status of Siberian flag (Iris sibirica L.) can be found. Leaf traits, phenological data, seed-set, thousand-seed weight, germination, growth rate and soil characteristic data are published based on original observations:

  • Leaf area is between 25,3 and 52,9 cm², its dry mass is 232 and 272 mg/g, specific leaf area is 14,5 and 15,0 m²/kg; based on measurement of 5–5 leaves of sibirica, collected from Tapolca and Létavértes (Hungary) in May of 2014.
  • Based on herbarium dataset, blooming of sibirica begins at the end of April and lasts to early-July, contrary to the literature data (May–June).
  • Capsules contain (0–)58–76(–121) fertile seeds. (20–)60–80(–90)% of ovules develops to (seemingly) viable seeds, meanwhile the other ovules remain as aborted ones or develop to infertile seeds (probably because of absence of resources); based on fruits collected from Regéc (Hungary) in 2014 and 2015.
  • Thousand-seed weight of sibirica is 8,8298–11,2914 g (based on 3×100–100 seeds collected from Regéc and Tapolca in 2014 and 2015), which is lower value than the literature data.
  • In our germination test (50–50 seeds sowed to wet soil, after different treatments) 14% of scarified seeds, 6% of scalded seeds, 4–4% of imbibed and control seeds, 0–0% of cooled and refrigerated seeds are germinated. Scarified seeds germinated in the 8–26^th days, imbibed seeds 15–19^th days, control seeds 16–20^th days, scalded seeds 20–23^th days after sowing. It seems that scarification stimulates, meanwhile temperature-treatments inhibit the germination. Until 18 weeks the seedlings grow to 30 cm (in mean) and develop 5–7 leaves (in mean). After the 14^th week, the first and littlemost lateral leaves are necrosed.
  • Analyses of soil samples collected from 17 locations of sibirica in Hungary, suggest that the species prefers highly acidic to slightly alcalic, lime-free to highly calcareous soils with generally high amount of humus and clay, different amount of phosphorus, potassium and nitrogen and low concentration of salt.

  In 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).

  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.

  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).

  The hybrid of leopard’s bane (Doronicum orientale Hoffm.) and the Hungarian leopard’s bane (Doronicum hugaricum (Sadler) Rchb.f.) was discovered by Tamás Nendtvich in the Mecsek Mts over Pécs in the 1820’s. During the past two centuries several researchers confirmed the occurrence of this plant in the region. The occurrences of the hybrid ever known are concentrated in a relatively limited range, and the single currently known occurrence is on “Zsuppon-parlag”.  In this paper, I report a new occurrence, found on 16th April 2020, close to the village of Kővágószőlős, which is 8 km away from the single currently known locality. I found only one flowering specimen, as well as five vegetative individ­uals with leaf rosettes. The parental species grew only 50 cm away from each other. Here, I provide a detailed morphological description about the flowering individual, and a vegetation relevé of the ac­companying species in a 10×10 m quadrat around the hybrid plant.

  In 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.
