  During the systematic floristic research along Transdanubian roads (NW Hungary) since 2013, two native halophyte Spergularia species has been found. Due to the well known spreading near motorways in Eastern-Central Europe, the appearance of Spergularia marina along roads in north-western Hungary is not a surprise. Occurrences of the species were registered along fourteen main roads. Some of the stands are very rich where S. marina forms single-species lines along the asphalt edge. The spreading of Spergularia media along roads is yet much less intensive. Four stands were found near the motorways M1 and M7, main road 74, and the common section of the main road 86-87. Both species are native in the Hungarian plains, being specific elements of Pannonic alkali grassland associations, however, their secondary migration along road edges is promoted by road salting, intensive management of roads and increased vehicle traffic. In this paper, we specify secondary occurrences of the two Spergularia species, discuss their ecological and abiotic circumstances and publish corresponding distribution maps. Due to recognition problems in Spergularia, a corrected determination key was provided.

  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).
