    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 ramosusHypericum dubiumLathyrus 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 rivulareDryopteris dilatataEquisetum telmateia), loess-connected species mainly on the Moson Plateau (Agropyron cristatumAllium atroviolaceumEuphorbia salicifoliaViola ambigua); and occurrences of species on sandy soils near the Lake Fertő (Draba nemorosaStipa pennata).
    • We explained the known localities of several salt tolerant species (e.g. Carex divisaCrypsis alopecuroidesJuncus maritimusLimonium gmeliniiSuaeda 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 tataricumBetula pubescensFraxinus ornusQuercus petraea, Salix pentandra).
    • We discussed the regional nature conservational status of several protected and/or threatened species (e.g. Allium carinatumAllium suaveolensCarex strigosaHottonia 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 paper presents 1593 current chorological data of 584 taxa (species, subspe­cies, varietas, hybrids) from Hungary, collected during the last few years. All of these connec­ted also to a total of 184 CEU quadrats. Among the species characteristic to the natural habi­tats, we high­lighted the records of several species protected in Hungary (Adoxa moschatelina, Althaea canna­bina, Cardamine parviflora, Centaurium pulchellum, Gagea pusilla, Orobanche reticulata, Potentilla patula, Rosa zagrabiensis, Spergula pentandra, Trifolium diffusum, Vale­rianella dentata, V. rimosa, Veronica officinalis, Viola collina and V. pumila). In the Northern part of Hungary, we observed the establishment of Cerastium dubium and Ranunculus peda­tus at several places along road­sides, which species have been known from the surrounding saline areas for a long time, but their appearance at roadsides is relatively new phenomenon. In addition, Aegilops cylindrica, Crypsis schoenoides, and Fumaria vaillantii subsp. vaillantii were found in one location – each species on roadsides. Along the railway tracks, we found disturbance-tolerant pioneers of rocky grasslands, open sandy and loess grasslands, e.g. many population of the native Androsace elon­gata, Anthemis ruthenica, Centaurea arenaria, Draba nemorosa, Erodium ciconium, Medicago monspeliaca, Microrrhinum minus, Saxifraga tridactylites and Vulpia myuros were found, as well as numerous ruderalia and the archae­ophyt such as Aegilops cylindrica. In addition to the more common species from the urban flora, we present some new data on the occurrence of the rarer Amaranthus blitum subsp. emarginatus, Chenopodium glaucum, Ch. murale, Ch. opulifolium, Ch. vulvaria and Euphorbia peplus. We have also listed some of the rarer field weeds and species that can establish in younger and older old-fields. Bromus secalinus has been found in several places in the north­eastern part of Hungary. We also observed Calepina irregularis, Centaurea solstitialis, Centau­rium pulchellum, Erysimum cheiranthoides, Filago lutescens, Fumaria officinalis subsp. of­ficinalis, Geranium dissectum, Misopates orontium, Myagrum perfoliatum, Reseda phyteuma, Sper­gularia salina and Veronica anagalloides populations. Erodium hoefftianum is a member of the natural flora, but is now found only in old-fields. We found some pasture weeds in re­gions where they are not common (e.g. Bupleurum tenuissimum, Cerastium dubium and Tri­folium striatum). The study also presents some species that are data deficient for taxonomic reasons, but not very rare ones (or we don’t know that). This group includes Arabis sagittata, Bolboschoenus glaucus, Bromus commutatus, B. racemosus, B. ramosus, Fumaria vaillantii subsp. schrammii, Ononis spi­nosiformis subsp. semihircina, Potentilla collina and Viola suavis “white morfotype”. We have drawn attention to the effect of ecological-botanical works on flora-influencing. We found An­themis ruthenica (species of sandy grasslands) in a moun­tain meadow, which is probably the result of seeds accidentally introduced by researchers. Finally, the paper provides data on the current distribution of hybrid taxa. A new individual of Betula ×rhombifolia was established in the Mátra Mts. We found some Euphorbia individuals that appeared to be a transitional form between E. esila and E. virgata (E. ×intercedens; Eu. esula subsp. saratoi). We also present some Verbascum and Viola hybrids. Hybrids were determined on a macromorphological basis.
