  In this study we present the current moss and liverwort flora of the Arboretum of Szarvas. The observations were made in 2017, 2019, 2020 and 2021. Altogether 95 bryophyte taxa (7 liverworts and 88 mosses) were identified. Most of them are considered to be common in Hungary, however some species are rare in the Great Hungarian Plain: Lophocolea coadunata, Climacium dendroides, Hylocomiadelphus triquetrus, Pleurozium schreberi, Polytrichum formosum, Rhytidiadelphus squarrosus, Ulota crispula, Zygodon rupestris. These results also confirm the conservational and scientific value of the arboretum.

  The botanical and ethnobotanical studies of PÉNTEK & SZABÓ (1985) were repeated after 30 years, during an ethnobiological summer school held in Kalotaszeg region (Romania), in Apuseni Mountains. However, our intensive floristical researches focused only on two villages (Sztána and Zsobok). A list of the observed taxa and their frequency values are presented. Of the 747 taxa 52 are new to the narrow region. 74 species reported formerly from here were not found by us. The disappearance of some taxa (e.g. Crepis praemorsa, Conringia orientalis, Lolium temulentum) are probably due to changes in agricultural land use methods. The spread of a few new invasive species (e.g. Ambrosia artemisiifolia, Galinsoga ciliata, Senecio vernalis) as well as the presence of some floristically interesting species (e.g. Centaurium pulchellum, Carex otrubae, C. serotina, Lathyrus pannonicus subsp. collinus, Leucanthemum irrcutianum, Minuartia viscosa, Peucedanum rochelianum, Quercus pubescens, Trifolium diffusum, T. micranthum) and a notomorpha (Cirsium × tataricum) were also noticed.

  So far, only one herbarium data and one flora mapping data on Kievan nettle (Urtica kioviensis Rogow.) has been known from the Southern Nyírség. Since 2004, the species has been detected in 14 flora mapping quadrats. Its data were also collected in winter because its habitats are more easily accessible on ice, its overwintering shoots are more noticeable, and they are strikingly morphologically different from the great nettle (Urtica dioica L.). Typical habitats were willow carrs (Calamagrosti-Salicetum cinereae), reeds (Phragmitetum communis), rush-beds (Typhetum latifoliae, Typhetum angustifoliae), tufted sedge communities (Caricetum elatae) and tall sedge meadows (mainly Caricetum acutiformis). The largest stocks live in reservoirs in secondary habitats. A significant part of the stocks is located in the wide valleys of the main watercourses in the area.

• The role of soil seed bank in restoration and dynamics of Hungarian plant communities

  Soil seed bank has an important role in maintaining plant populations and communities, in regeneration processes, and also provides information about the history of the studied site, the past land use practices, the biotic and abiotic changes and about the current degradation degree. In Hungary there are many researchers related to the seed bank, but from the last few years we do not have a comprehensive work about the results of these works. My goal is to report on the results of former seed bank researches in Hungary and also to highlight the missing topics and further research opportunities. The review is based on 49 articles, the oldest one dates back to 1922, the newest one was published in 2015. Most of the studies use greenhouse or laboratory germination tests to determine the viability of seeds. The earliest studies, which examined the weed seed bank of farmland soils found, that the seed bank was much higher than the total seed bank found on natural and semi-natural habitats studied later. Researchers found the lowest seed bank density in forests. Disturbed sites and former agricultural sites had higher seed bank densities than sites without agricultural use. Most part of seed bank was located in the upper soil layer in all studied communities. In most studies usually a small similarity was detected between the composition of soil seed bank and aboveground vegetation, which suggests that the seed bank has a subordinate role in regeneration processes. Seed bank type classification is lacking from the three-quarter of Hungarian flora species, despite that it is essential for protecting species and communities and for developing proper protection against invasive and alien species.

  The presence of Spiraea media on the Balaton Uplands has high plant geographical importance, but the found location has not been known before its recent rediscovery. The Spiraea media was discovered on the Kopasz Hill (Felsőörs) growing in a closed Quercus cerris oak forest (~Fraxino orni-Quercetum cerridis); which is a rather atypical habitat of the species. The appearance of blooming specimens and the rediscovery of the species is probably due to the cut of the neighbouring forest, which has resulted extra irradiation in the area. The 19^th century military maps of the landscape show that the former vegetation of the area was characterised by the mosaics of rocky grassland–scrub–forest or rocky scrub rich patches being suitable for the species.

  The paper summarizes the previous history and recent purposes of the ‘Wildflower of the Year’ initiation, established in 2011. The main aim of this initiation is the promotion and familiarization of Hungarian flora, applying a public awareness campaign about the beauty, importance and ecological value of our spectacular wild plants. The ’Wildflower of the Year’ is selected by voting on internet (www.evvadviraga.hu). Starting from this volume the journal Kitaibelia publishes a monograph about the wildflower of the previous year.

  Results of nearly two decades of floristic research in the territory of Heves–Borsod Hills (Tar­na-vidék) and the northern foreground of the Bükk Mts are presented in this paper (altogether 4421 re­cords; BÁ: 1665, SJ: 2752). Several old literature records – partly supported by vouchers – are confirmed, e.g. Hypericum elegans and Lappula heteracantha from the Uppony Gorge, as well as Cephalaria tran­s­syl­va­ni­ca, Cypripedium calceolus, Diplotaxis erucoides and Plantago indica from the Heves–Borsod Hills and the nort­hern foreground of the Bükk Mts. Other former literature records (partly from the authors) are re­vi­sed. These revisions are mainly due to changes in taxonomic concepts of some genera in new keys (Carex, Cha­maecytisus, Epipactis, Molinia, Sorbus). Old literature and herbarium records of other significant taxa (Onos­ma visanii, Scutellaria columnae, Sorbus sp., Utricularia bremii/minor) are revised too. The new occurrence of Ferula sadleriana in the Uppony Gorge is probably the result of intentional seed dispersal. Of the many rare plants listed in our paper some are new for the flora of the region under study: Ag­ri­mo­nia procera, Alchemilla micans, Asplenium adiantum-nigrum, Astragalus austriacus, A. exscapus, Blysmus compressus, Carex appropinquata, C. cespitosa, Catabrosa aquatica, Centarea indurata, Dactylorhiza × as­cher­soniana, Epipactis voethii, Epipogium aphyllum, Equisetum hyemale, Festuca drymeja, Gagea bohemica, Gly­ceria nemoralis, Hesperis sylvestris, Myosotis caespitosa, Phegopteris connectilis, Platanthera chlorantha, P. × hybrida, Rosa gizellae, Scilla kladnii, Senecio doria, Solanum villosum, Taraxacum palustre, Triglochin pa­lustre. Two phytocoenological relevés representing the habitats of Myosotis caespitosa and Spiraea me­dia are presented. Currently known local distribution of some montane and forest-steppe elements are shown on maps.

• Historical occurrence of Spergularia echinosperma, a rare Nanocyperion species in Hungary

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

  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).

  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).

  Vulpia 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.

  Some 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.

  Euphorbia 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.

  Four ephemeral Lythrum species have been recorded from Hungary so far. Lythrum hyssopifolia is widely distributed in the whole country. Most occurrences of L. tribracteatum are located in southeastern Hungary and alongside the Danube. The Central Asian L. linifolium was reported from a single locality (Tiszaug village, E Hungary) in 1954, which is the only European record of this species. However, we have ascertained that the voucher specimen of this record differs from L. linifolium in some morphological traits, but strongly resembles L. borysthenicum that is distributed in the Mediterranean and steppe regions of eastern Europe. Based on our revision we suggest deleting L. linifolium from both Hungarian and European checklists. The former Hungarian occurrence of L. thesioides is confirmed by vouchers.

  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).
