    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).

    Based on a substantial field-work and herbarium revision carried out between 2007 and 2014, the authors present the taxonomical evaluation of recently known representatives of Rubus L. ser. Micantes Sudre in Hungary, providing the first grid-based distribution maps and an identification key of four species of the section (Rubus balatonicus Borbás, R. clusii Borbás, R. styriacus Halácsy, R. tabanimontanus Figert) for Hungary.

    The authors report on the occurrence, distribution and invasion potential of Rubus armeniacus, a bramble species of Caucasian origin, in Hungary. The first verified records of the species are from the 1990s. It has established strong populations in ruderal habitats mainly around Budapest and some other cities, whereas its competiveness is rather weak in closed non-lowland forests rich in native bramble species. In terms of conservation, it constitutes a real threat to the vegetation of Pannonian sandy habitats. The results of this study also emphasize the importance of recognising "nonnative cryptic species" for ecology and conservation biology.
