  The plant that was reported as Vaccinium oxycoccos L. from the Nyírjes-tó (Sirok village, NE Hungary) in 1994 was subsequently (1999) identified as Vaccinium microcarpum (Turcz. ex Rupr.) Schmalh. by the first author of this article. To substantiate this identification morphometric data were collected and analysed from Vaccinium specimens occurring in the Sphagnum dominated mires of Nyírjes-tó (Sirok vilage) and Nyíres-tó as well as Báb-tava (Bereg-plain) in September 2016. Field photographs taken previously at the localities of Bereg-plain were also used for identification. The leaves of the Sirok plants are smaller, ovate-triangular, i.e. widest near base. The ovate-elliptic bracteoles are inserted on the basal third of the glabrous pedicels. The flowers are solitary, and have dark pink corollas and hairy filaments on the whole abaxial surface. The fruit is pyriform. In contrast to the Sirok plants, those of the Bereg-mires have clearly larger and ovate-elliptic leaves. The filiform bracteoles are inserted on the middle third of the minutely hairy pedicels. The whitish flowers are grouped in clusters of (2)–3–4–(5), i.e. they form an inflorescence. The filaments are hairy only on the margins of the abaxial surface. The fruit is globular. The statistical analysis confirmed that the Sirok plants belong to V. microcarpum, whereas the Bereg-plain plants represent V. oxycoccos.

  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 present paper focuses on the aquatic and Nanocyperion vegetation of the Danube flood­plain. Most of the data show the results of the surveys in 2019 at low water levels. The Nanocyperion and aquatic vegetation of the Komárom-Esztergom County section is relatively well researched com­pared to the Fejér County section which was previously poorly known. In the last decade, two rare spe­cies – Hippuris vulgaris and Hydrocharis morsus-ranae – have disappeared between Gönyű and Neszmély (Komárom-Esztergom County). In contrast, several new invasive plants have appeared: Salvinia molesta, Myriophyllum aquaticum, Limnobium laevigatum, and Crassula helmsii (first record from Hungary). Vallisneria spiralis and Elodea canadensis were detected again after several decades. Elodea nuttallii and Azolla sp. have become more widespread and abundant than previously. New and uncommon Nanocyperion species were the native and protected Lindernia procumbens and the inva­sive Lindernia dubia. New invasive plants in the studied Danube sections were: Cyperus esculentus, Euphorbia maculata, and Eleusine indica. The native Veronica catenata and Schoenoplectus triqueter have become more wide­spread than before. Polygonum graminifolium was an interesting find of open pebble surfaces in several parts of the examined area, which has no recent records in Hungary from before 2015 (published here).

  The paper introduces the herbarium of Eötvös Loránd University (BPU), currently stored at the Botanical Garden of the University, according to its state in the year 2013. The BPU herbarium consists of ca. 16 000 specimens the relevant data of which have been organised into an OpenOffice Calc spreadsheet database. The specimens were collected in 16 European countries, mainly in the current territory of Hungary (80%), Romania (12%) and Slovakia (5%). Other countries are represented with very few specimens. The vast majority (ca. 70%) of the Hungarian specimens were collected in Pest, Veszprém, Borsod-Abaúj-Zemplén, Hajdú-Bihar and Szabolcs-Szatmár-Bereg counties. Although the gatherings cover a century and a half period of time, the most rapid growth of the collection took place from the 1930s to the 1960s. The most prolific collectors were Rezső Soó and his followers: Lajos Felföldy, Tibor Simon and Szaniszló Priszter. Felföldy and Simon enriched the collection through more than 60 years. Data on the native plants collected in the present-day Hungary are summarized in Electronic Appendix 1. (incl. taxon name, settlement, collecting year, collector, file name of documentary photograph).

  This paper presents the results of the first bryofloristic survey in kurgans from North East Hungary. Altogether 41 taxa (1 liverwort and 40 mosses) were recorded from nine burial mounds. The most frequent mosses were Brachythecium rutabulum, Tortula acaulon var. acaulon and Barbula unguiculata from the localities. I found several infrequent bryophyte species on the surveyed Hungarian kurgans, such as Acaulon muticum, Acaulon triquetrum, Pterygoneurum subsessile, Riccia ciliata, Tortula caucasica, Trichostomum brachydontium and Trichostomum crispulum. There was no correlation between the number of bryophytes and the area of the kurgans. The proportion of the annual shuttle life strategy, i.e. species with a very short life span, is relatively high compared to other recent studies from Hungary (e.g. Buda arboretum and Balaton village), thereby these habitats may be potential refuges for ephemeral bryophytes.

  A 0.26 km2 sized Natura 2000 area called Bolondvár, located in Central Hungary, near the village Mezőfalva was studied. It is used regularly as a meadow or sometimes as a pasture. Floristic data were collected between 2010 and 2013. The total number of taxa recorded was 362. The species diversity was high compared to other places of Hungary. There were 11 protected (e.g. Ajuga laxmannii, Astragalus asper, Cirsium boujartii, Inula germanica) and numerous locally rare species (e.g. Hieracium densiflorum, Lavatera thuringiaca, Orobanche lutea, Veronica austriaca).

  This paper presents occurrence data of 169 taxa from the Lengyel–Hőgyész Natura 2000 site (HUDD20026) which is on the southern part of Tolna Hills, SW Hungary. Data were collected during three years (2015, 2016, 2017), on different sites annually. The presented data contribute to the distribution dataset of Atlas florae Hungariae. Regionally rare or sporadic species (e.g. Asplenium scolopendrium, Asplenium trichomanes, Polystichum setiferum, Doronicum hungaricum, Paris quadrifolia, Scilla vindobonensis) are enumerated. Presence of Epipactis leptochila subsp. neglecta and Platanthera chlorantha were not registered from this site before. Subspecies of Carex divulsa are also studied on this site – distribution of these infraspecific taxa have not been mapped recently in Hungary.

  The paper introduces the “Zoltán Siroki Herbarium” (on the basis of the MS Excel spreadsheet database of the collection) which is a separate section within the Herbarium of Debrecen University (DE). The Zoltán Siroki Herbarium consists of ca. 20 000 specimens from almost all European countries, but mainly from the historical territory of Hungary. Although ca. 400 botanists contributed to this collection, most of the specimens were collected by Zoltán Siroki in Hajdú-Bihar, Pest and Borsod-Abaúj-Zemplén counties. The most rapid growth of the Herbarium took place in the middle of the last century (from the 1940s to 1960s), but Siroki remained an active collector until the 1980s. Some specimens from the Herbarium of former Royal Seed Testing Station (Budapest) was also incorporated in this collection; they represent gatherings from the last decades of  the 19th century and first decades of the 20th century. Data on the most significant part of the collection, representing native plants collected in the present-day Hungary, are summarized in Electronic Appendix 1. (incl. taxon name, settlement, collecting year, collector, file name of documentary photograph).

  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).

Species characteristic of reed and sedge marshes, salt lakes and alkali flats, as well as remnants of hardwood forests and mesoxeric grasslands are listed in the enumeration. Since 2004, I have confirmed the occurrence of 50 species previously not recorded in the study area. Here, I report the species names, followed by data on the locality: the name of the township, the geographical name of the locality, and the code(s) of both grid systems, the Central European Flora Mapping System (CEU) and the UTM. Sites where I observed or collected the species after 2004 are in bold. Names of species new to the study area are underlined.

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 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.

  Verges 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.

  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.

  Caldesia parnassifolia is a critically endangered and strictly protected species in Hungary. It was known only from one locality of occurrence so far, where it was last reported in 2003. Its new occurrence was discovered in Somogy county, in 2010. It appeared in an artificial pond created in the place of an originally swampy depression. Based on this newly discovered occurrence we can assume that other potential populations might still exist in South-Transdanubium, which could be rediscovered if similar conservation measures occur.

  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.

  During an extensive field work in the acidophilous forests and fens of the Western Mecsek Mts. current localities of several species, which haven’t been recognised here for 50 years, were revealed (e.g. Bazzania trilobata, Diphyscium foliosum, Scapania nemorea). The authors also found some new stands of regionally and/or locally rare taxa (e.g. Buxbaumia aphylla, Dicranum tauricum, Jamesoniella autumnalis, Lepidozia reptans, Sphagnum squarrosum) as well as species new to the moss flora of the Mecsek Mts. (e.g. Aulacomnium androgynum, A. palustre, Calliergon cordifolium, Hedwigia stellata). Both investigated habitat types were found to be infected by invasive moss (Campylopus introflexus) and liverwort (Riccia rhenana) species. It is noteworthy that most of the species were found in winter or at the beginning of spring, when most vascular plants are inactive and their coverage is negligible. In this period moss and liverwort taxa are active, and are therefore easily noticeable. The authors raise the possibility that the expansion of Dicranum tauricum in Hungary is a consequence of former coniferous (especially Pinus spp.) plantations, since the old, dead trunks of pine species can serve as stepping stones to colonization for this taxon.
