In this contribution, new data concerning the distribution of vascular flora alien to Italy are presented. It includes new records, confirmations, exclusions, and status changes for Italy or for Italian administrative regions. Furthermore, three new combinations are proposed. Nomenclatural and distribution updates published elsewhere are provided as Suppl. material 1.

BevezetésA magyarországi edényes fl óra kutatása az 1990-es évek eleje óta meglehetősen aktív fázisában van, ezt bizonyítják a sokasodó fl orisztikai dolgozatok és egyes nagyobb (nem feltétlenül csak a fl orisztikára szorítkozó) összegzések. Utóbbiak (a legjelentősebbek Farkas 1999, Király 2009, Molnár 2011 szerepe nem csak a nagy tömegű adat összegyűjtésében és rendszerezésében jelentős, hanem egyben ráirányítják a fi gyelmet a kevéssé ismert fajokra, fajcsoportokra, illetve a hiányosan ismert fl órájú tájakra.

Data to the flora and geobotany of Kisalföld (Lesser Plain) region, NW HungaryAbstract -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 submontanemontane 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).Keywords: floristic studies, geobotany, nature conservation, salt tolerant species, steppe flora Összefoglaló -A Kisalföld flórája számos kistáj és növénycsoport tekintetében kifejezetten jól feltárt, de akadnak nagyon hiányosan ismert területei is, elsősorban a régió nyugati részén. A szerzők 2001-2014 közötti terepkutatásaik legfontosabb kisalföldi eredményeit adják közre a dolgozatban, amely 57 taxon adatait tartalmazza. A Kisalföld magyarországi oldalára új 5 faj (Brachypodium rupestre, Bromus ramosus, Hypericum dubium, Lathyrus sphaericus, Tordylium maximum) felfedezése. Számos faj egyes kistájakra nézve jelent újdonságot, a legtöbb ilyen adat azokról a kistájakról származik, amelyeket korábban alig vizsgáltak (Fertő-medence, Ka...

Vegetation survey of the great bustard conservation area MOSON Project has been carried out in the period 2004-2010. The aim of the survey was to analyse the habitat types and to present the endangered plant communities and segetal species. During the fieldwork 5 types of vegetation were distinguished -cereals, peas, rapeseed, fallow land, and grasslands -and a total of 267 phytosociological relevés were prepared. The average number of species per relevé was explicitly uniform in the cultures examined (14.73-17.12 species). The proportion of weed species was high in the crops, while in the fallows and grassland areas the segetal weed species and the pioneering dry meadow species can also be found. The number of indicator species of the segetal flora and the dry meadows is most significant in the cereal crops, but many species survive in fallows land and even in the grasslands. This indicates that the regular temporary use of agricultural strips can stabilize the pool of species in the wider area for many years. The number of dry grass species in the meadows is not significantly higher than in the cereals or fallows, but they dominate in the overall coverage (5.17%). Carduus acanthoides shows the highest average coverage in the model area (9.66%), followed by Bromus sterilis (6.24%) and Arrhenatherum elatius (5.85%). There are hardly any generally dominant species in regularly disturbed cultures, which are relatively diverse. In contrast, the cover of the top 10 species in fallow and grassland areas are over 60%, as a few competitive species are displacing the others due to natural succession. The soil site and habitat conditions of the Moson plain offer favourable conditions for segetal weed species. Dry climate and flat soils effectively inhibit succession processes. The total coverage of sensitive segetal weed species varied between 3.13 and 22.80% in the different crops during the study period. Only Anthemis austriaca and Vulpia myuros showed a permanent value above 1%, otherwise Consolida regalis, Filago arvensis, Galium spurium and Scleranthus annuus occasionally achieved a significant average coverage.
