  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.

  We 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.

  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).

  Dr. Sándor Polgár was the most outstanding botanist of Győr county (NW Hungary). He provided important results in floristic studies, phytogeography, taxonomy and in the research of alien plants. „Győr megye flórája” („Flora of Győr county”), published in 1941, was one of the most important monography in his period. He is the author of the rare, hybridogenous species Ornithogalum ×degenianum, known only from Hungary. His private herbarium was one of the biggest in Hungary with more than 20,000 specimens. As a teacher he taught geography and nature studies in his home town Győr between 1900 and 1935. Because of his Jewish origin, he was a victim of the holocaust in 1944.

  The subgenus Ceratochloa is a taxonomically difficult small group of the genus Bromus. The species of this subgenus are mostly native to America, and are often introduced to other continents. Two species of them, namely B. catharticus and B. carinatus have been reported from Hungary so far. Bromus catharticus was first found in Győr city in the 1910s, much later (in the 2000s) in Környe and Kálmánháza villages. The Hungarian records of B. carinatus come from Keszthely and Sopron cities. We have recently found two new occurrences of B. catharticus in the city of Pécs, South Hungary.

  Crepis hieracioides (= C. mollis subsp. hieracioides) was described from the Bakony Mts. (Western Hungary) by Pál Kitaibel more than 200 years ago. His record has been the single one of this taxon from the territory of present-day Hungary thus far. In the second half of the 20^th century this taxon was either reported as ‘extinct’ or was plainly ignored in the Hungarian literature. This paper reports about the recent rediscovery of C. mollis subsp. hieracioides in the Bakony Mts., specifically in the ‘Bakonyalja’ region (Devecser: Széki-erdő). The habitat is characterised, and the regional phytogeographical significance of this taxon is emphasised.

  The first occurrence of blue lettuce (Lactuca tatarica (L.) C.A. Mey.) is reported from Hun­ga­ry. Information on its taxonomy, morphology, distribution, habitat preference and nature conservation aspects is presented. The European local spread of this Eurasian and North American species started at the end of the 1800s. The first localities were reported from the shores of the Baltic and North Sea. Its alien occurrences in inland European regions have been noticed since the 1920s. As L. tatarica have pre­viously been known from the neighbouring territories of Slovakia and Austria, its appearance in Hun­gary is not at all unexpected. However, the species was found (August 2018) in the southern part of Csongrád county, i.e. far away from the above-mentioned countries. Due to the species’ habitat preference (ruderal ground), ecological requirements and successful vegetative propagation, which correspond to foreign observations, its future spread is highly probable.

  In the course of our research of Hungarian transport routes, we observed an intensive spread of the Atlantic-Mediterranean Plantago coronopus L., a recently established species in Hungary. Between 2017 and 2019, it was detected in 47 flora mapping quadrats, which increased the total number of occurrences to 81 since 2013. Besides motorways, the main Hungarian transport routes were involved as well. 26 occurrences have been recorded along the roads 4/E60, E573, 8/E66, 86/E65 and 87, which are severely affected by international traffic. However, on routes avoiding international transit traffic, the species’ occurrences are still rare. In some cases, the predominant direction of traffic appeared to influence the formation of new stands. It is very likely that the first individuals that appeared along the section of the M86/E65 motorway between Szombathely and Hegyfalu in 2019, arrived primarily by northbound traffic, rather than along the road 86, which runs parallel to it only a few hundred meters away. Likewise, it seems certain that the spread of the species along the roads M1/E60, E75 (Mocsa, Tata, Páty) and M7/E71 (Fonyód, Balatonlelle, Kajászó) as well as the road 8/E66 (Bakonygyepes, Veszprém) is due to reproduction of older extensive local populations. At several localities along the outer bend of roundabouts or near the exits of motorways, a dispersal role of intense winter road salting was also observed. The largest populations were located mostly along ditches, next to the (often bare) lane of roadbeds that are heavily affected by mechanical and osmotic stress. The majority of stands were found within a 3 meters wide belt along the asphalt strip (5 meters was measured in the lawn of a cemetery once). Since the species is present continuously at several localities since 2013, it is considered as naturalised in Hungary, and its further spread can be confidently predicted. The current status of the species in Hungary is naturalised (non-trans¬former) neophyte.

  Torilis nodosa (L.) Gaertn. is an Atlantic-Mediterranean weed species. Its old data are known from Budapest, but these may have been occasional occurrences, the species has not been confirmed in Hungary for more than a hundred years. In the last few years, we have found six new occurrences of the species in Hungary, one population in Budapest, and another five in some settlements on the northern shore of Lake Balaton. The species was observed in ruderal or intensely mowed urban habitats, in all cases. Intensive tourism has a role in its introduction for sure, but for the survival of self-sustaining stands and in its already perceptible regional spreading, the climate change trends, the increasingly mild winters, and the decreasing number of frost days could also be important. New data from Hungary are well connected to its other Central European observations.

  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.

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.

  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.

  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.

  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.

• 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 the legacy of Sándor Jávorka deposited in the Hungarian Natural History Museum there is a 12-page typescript entitled “An identification key for Hungarian botanists portrayed in Album Kleinianum (Budapest, 25 September 1912)”. It provides accurate descriptions of 50 botanists in the form of an identification key, which was compiled by Zoltán Szabó, a well-known botanist at that time. The most important features of each person are presented in a humorous, basically ironic, funny and witty way. The Identification key was prepared for the session no. 178 of the Botanical Section of the Royal Hungarian Natural Science Society, where another botanist, Gyula Klein was congratulated on the 40^th anniversary of his teaching profession as well as the 20^th anniversary of his membership in the society. Almost all prominent botanists attended the meeting. This paper presents the Identification key, supplied with annotations and photographs.
