  Najas gracillima, an introduced species to Europe, naturally occurs in East-Asia and NorthAmerica. It was firstly discovered in Hungary in 2012 in our weed survey of rice fields in the vicinity of Szarvas, Gyomaendrőd and Mezőtúr. Although, it occurred in relatively high abundances in the rice fields along the Körös river its invasion is not expected into new habitats in the near future due to its special habitat preference and gregariousness.

  Himantoglossum adriaticum H. Baumann is a Natura 2000, CITES species and strictly protected plant in Hungary. During my field work (1992–2016) I realized some similarities in the characteristics of the habitats where the plant grows, so I wanted to know the land use history of the areas in question. The H. adriaticum population of Keszthely Hills was studied the longest time. There were annually 7–78 inflorescences between 1992–2016. Recently two further localities were found in Keszthely Hills. They grow in the edges of grasses used earlier as pasture, minor roadside verges and nearby abandoned vineyards. The largest population can be found in Sümeg region, majority of the individuals are along a paved road. Among the estimated 1000–2000 individuals 10 (2012) to 214 (2014) flowered. In Kőszeg, the lizard orchid grows in abandoned vineyards and in old traditional orchards. The maximum number of inflorescences was 165 (2016). In Bakony Hills its habitats are vineyards and orchards abandoned approximately 50 years ago. The size of H. adriaticum population here is nearly the same as in the Keszthely Hills. Four out of the five populations are growing on sites used as vineyard or orchard already in the years of the First Military Survey. The only exception is the population of Sümeg region. Every habitat is threatened by spontaneous forestation, but the species is able to find new habitats, so we do not worry about the drastic decline of the individuals in Hungary.

  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).

• The degradation of hygrophilous plant associations of the Nyárjas Lake (E Hungary)

  The Nyárjas Lake (located near Kállósemjén, East Hungary) was one of the most typical bogs in the Nyírség until the early 1980’s. Most of its area was covered by the association of Carici-Menyanthetum. The number of species characteristic to the mentioned association was generally high. As the climate became drier, hotter and were characterised by higher magnitude of extremities, the water coverage became no longer as permanent. This resulted that the Menyanthes trifoliata and Listera ovata became extinct by 2000. Lemno-Potamea species were not found after 2010. Bidentetalia, Calystegietalia, Chenopodietea and Secalietea species became more prevalent, particularly in drier periods, and locations where Carici-Menyanthetum used to be characteristic. Cirsium arvense in the mid-1990’s and that of Urtica dioica in the mid-2010’s became dramatically abundant. Both the number and coverage of species indicating habitat degradation have increased. The composition of wet meadow plant associations shifted towards the drier Arrhenatheretea. A moderate revitalisation of wetland associations was, however, observed coinciding years with higher precipitation.

  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.

  Dr. Antal Waisbecker (1835–1916) was a Hungarian physician and the most prominent botanist of Vas county (West Hungary) at the turn of the 19–20^th century. He contributed with important floristic data for the botanical monography of Vas county, authored by Vince Borbás. He processed the pteridophytes of Vas county and cormophytes in the surroundings of Kőszeg. Antal Waisbecker was an expert in the knowledge of sedges too. He discovered and described the Carex fritschii. Remarkable amount of herbarium specimens collected by Waisbecker are deposited at the Savaria Museum (Szombathely, SAMU) and Hungarian Natural History Museum (Budapest, BP).

  Fragments of the natural grassland vegetation are often preserved only in those areas which are inadequate for arable farming. In many cases kurgans hold the last remnants of dry grasslands in lowland areas, like the Great Hungarian Plain. They also have an essential role in preserving cultural and landscape values. Moreover, they harbour several rare plant and animal species. Our aim was to explore the vegetation of the Mondró-halom kurgan (Hencida, East Hungary). Altogether we found 74 vascular plant species in the loess grassland of the kurgan. Several rare species of the Bihari-sík region, such as Inula germanica, Ranunculus illyricus and Rosa gallica were also detected. The steep slopes of the kurgan with various micro-sites and exposures supported a species-rich vegetation. Instead of its small area it harboured several forest steppic species and several steppic flora elements (Continental, Pontic-Mediterranean, Pontic, Pontic-Pannonic and Turanian).

  A conservation survey on the condition of steppe and forest-steppe habitats in the Vértes Mts revealed several plant species from the flora of the area that have not been reported before. From a phytogeographical point of view, the most important is Astragalus vesicarius, whose small population in the Vértes fits very well into the native distribution pattern of the species in Hungary. Another important steppe plant is Stipa dasyphylla, which is found in two locations in the Vértes Mts. Besides other taxa of conservation interest (Orobanche teucrii, Phelipanche purpurea, Rosa hungarica), some under-recorded species (Cerastium tenoreanum, Stellaria pallida), and some spreading weeds (Elymus elongatus, Euphorbia lathyris) enrich our knowledge of the flora of the area.

  The 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 20^th 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 19^th 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.

  Acer opalus Miller 1768 because of its complex taxonomic status can be interpreted as a collective species which contains several species and subspecies depending on different interpretations. An important adventive occurrence from this collective species was found in a forest that belongs to the Tétényi plateau (Budapest, 11th district) in July of 2009. It is proved to be Acer opalus Mill. subsp. obtusatum (Waldst. et Kit. ex Wild.) Gams. The natural range of the subspecies covers the eastern side of the central Mediterranean Sea region and western Balkan Peninsula. It is a submediterranean-mediterranean, thermophile, shade-tolerant taxon but often appears together lightdemanding species too. In its native range it occurs in beech, pine, sessile oak forests and in different types of dry oak forests as admixed tree species. The subspecies was found in a turkey oak – sessile oak community in Hungary. Several old, seed growing individuals live on the spot which have had continuous seed production. Therefore from the old trees to the young seedlings different age categories are represented.

  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.

  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.

  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 phytosociological characterization of closed oak forests occurring in the loess-covered part of Central Hungary (Mezőföld) is presented. Such forest fragments are found very sporadically in that predominantly treeless region, mostly in semi-dry habitats of north-facing hillsides. This plant community represents an intermediate stage between open steppe woodland (Aceri tatarici-Quercetum pubescentis-roboris) and closed mesic oak-hornbeam forests (Corydali cavae-Carpinetum). Analyses of 20 phyto­sociological samples using multivariate grouping methods (cluster analysis, principal coordinates analysis) showed a clear difference between these samples and samples of similar communities occurring in the area. In the species composition the characteristic elements of dry and mesic oak forests (Quercetea pubescentis-petraeae, Quercetalia cerridis, Aceri tatarici-Quercion and Fagetalia, respectively) played a major role. On the other hand, dry grassland species (Festuco-Brometea, Festucetalia valesiacae, Festucion rupicolae, etc.) were much less significant than in steppe woodlands. In terms of chorology, European and sub-Mediterranean floristic elements were dominant in the samples, while the proportion of continental elements was substantially smaller than that in steppe woodlands. As a result, our samples were identified with the plant association Pulmonario mollis-Quercetum roboris Kevey 2008, which is classified into the suballiance Polygonato latifolio-Quercenion roboris Kevey 2008 in the phytosociological system.

  Floristic data were collected and habitat mapping was performed between 2009 and 2011 in the valley of Cuha-creek. During the field work occurrences of 423 vascular plant species (including 31 protected taxa) were recorded. Potentilla indica represents a previously unknown alien taxa of the study area. The dominant vegetation type of the Cuha-valley is beech forest. Further characteristic, important habitats are scree, ravine and hilltop forests. On the southern part of the valley – in close proximity of the Cuha-creek – expansion of several alien plants (Impatiens glandulifera, Fallopia spp., Heracleum mantegazzianum) were observed.
