  This paper lists supplementary data to the recently published Atlas Florae Hungariae, mostly from various parts of Transdanubia and the Great Plain. The list includes 73 plant species with at least one new occurrence previously not shown on their grid-based range map, as well as data confirming old records or correcting erroneous distribution data. The actual habitats where the plants occur are characterized by their corresponding ÁNÉR codes.

  The Alsó-erdő peat bog near Kőszeg has undergone a significant transformation since its first mention in the literature. In addition to the original single patch, a smaller one appeared a few decades later. The process did not stop and a third unit, discussed here, was formed. The succession of its macrovegetation towards the typical peat moss association started slowly but surely, due to balanced water regime and other optimal environmental conditions. The process is more advanced for the algal vegetation, which shows the characteristics of peat bogs already. The high species diversity found makes the habitat highly valuable itself. Although a special, unique algal species has not been found in previous studies, 27 Desmidiales taxa listed as endangered occur sometimes with high density and make the habitat even more valuable. Based on our results, the area deserves special attention both from the habitat conservation and research point of view. At the same time, its further monitoring can provide crucial information for exploring and understanding the succession of similar habitats, and thereby for their more efficient protection.

  Related to distribution of S. aria s.l. × S. torminalis hybrid taxa in the eastern part of the Balaton Uplands just data of „S. balatonica” is in the literature based on collection of Ádám Boros (Kárpáti 1960). In the summer of 2014 the author found and mapped a few (sub)populations of S. aria s.l. × S. torminalis at Lovas (Királykúti-völgy, Atya-hegy, CEU: 8973.4) and Felsőörs (Malom-völgy, Kopasz-tető, CEU: 8973.4) villages. Based on leaf-morphological traits the specimens were identified as S. udvardyana.

  Loess grasslands are among the most important vegetation types of the Great Hungarian Plain. This paper compares the composition of vegetation situated on three types of man-made landforms (burial mounds, Devil’s dykes and river dikes) which were built in different historical times. I studied the similarities and differences in their vegetation, focusing on the rare species and plant associations. I studied six burial mounds, two Devil’s dykes and four river dikes. All of the studied landforms were covered by loess steppes, loess cliffs or Artemisia salt steppes. Devil’s dykes had the most valuable vegetation and they preserve a very diverse flora in the landscape.

  A recent floristic mapping of the Velence Hills has clarified the local distribution of many plant species. This study presents records of 219 phytogeographically significant or sporadic/rare taxa (216 species/subspecies and 3 natural hybrids). The local distribution of some species representing typical regional distribution patterns (Alyssum turkestanicum, Artemisia austriaca, Bupleurum pachnospermum, Doronicum hungaricum, Hypericum elegans, Lathyrus sphaericus, Minuartia viscosa, Ornithogalum comosum, Scabiosa canescens, Sedum caespitosum, Sternbergia colchiciflora, Vinca herbacea) are shown on maps. More than fifty taxa previously unknown from the area were recorded during the floristic mapping, including phytogeographically significant ones, such as Bassia laniflora, Brassica elongata, Bupleurum praealtum, Centunculus minimus, Hypericum elegans, Orlaya grandiflora, Phleum bertolonii, Silene dichotoma, Stipa tirsa, Tordylium maximum, Trifolium diffusum, T. ochroleucon and Valeriana dioica. In terms of phytogeography, the Velence Hills can primarily be characterised by the co-existence of continental and sub-Mediterranean elements as well as species of acidophil and strongly basic habitats.
