  In the company of a single individual of Asplenium trichomanes L., several individuals of Asplenium ruta-muraria (L.) Hoffm. and a single individual of Dryopteris filix-mas (L.) Schott, 15 individuals of Asplenium ceterach L. (s.str.), and a single individual of Polystichum aculeatum (L.) Roth were found on a NW facing mortared sandstone wall of the copy of Eger Castle in the Pilis Mts. Asplenium ceterach s.str. is new to the flora of the Pilis Mts. The source population of this stand is probably located in the Buda Mts (Remete gorge) and this fern may have appeared on this wall 5–10 years ago at the latest.

  A conservation survey on the condition of steppe and forest-steppe habitats in the Vértes Mts revealed several plant species from the flora of the area that have not been reported before. From a phytogeographical point of view, the most important is Astragalus vesicarius, whose small population in the Vértes fits very well into the native distribution pattern of the species in Hungary. Another important steppe plant is Stipa dasyphylla, which is found in two locations in the Vértes Mts. Besides other taxa of conservation interest (Orobanche teucrii, Phelipanche purpurea, Rosa hungarica), some under-recorded species (Cerastium tenoreanum, Stellaria pallida), and some spreading weeds (Elymus elongatus, Euphorbia lathyris) enrich our knowledge of the flora of the area.

• Data to the distribution and nature conservation of Sorbus bakonyensis

  Sorbus bakonyensis (Jáv.) Jáv. (syn. S. majeri Barabits) is an apomictic species with a very narrow distribution range in the Bakony Mts (Hungary). Its previous occurrence data were published only from Kopasz Mt. (~Kápolna Hill, Csordás valley) above the village Márkó. It was possible to slightly expand the known area of the species to the East and to the West (Kis-Bükk Mt) of Kopasz Mt. with a detailed mapping. Due to the number of known individuals (six mature trees and a variable number of seedlings) and its small distribution range (~2 km²) the species is critically endangered. Regarding its small population, the high number of big game (wild boar, red deer) and the more and more frequent drought periods are significant risk factors. In situ preservation of the species is still a realistic goal, but ex situ propagation in tree nurseries and reintroduction to the suitable habitats of the mapped area (clearings, forest edges) are also justified.

  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.

  Here, I report Epipactis occurrences new to the flora of the Vértes Mts (Transdanubian Mts, north-western Hungary).  In 2020, new populations of Epipactis pontica Taubenheim, E. moravica Batoušek and E. pseudopurpurata Mered’a were found in old mesic beech and mixed beech forests.

• Contributions to the knowledge of biology and Hungarian distribution range of Orobanche reticulata

  Some new Hungarian occurrences of Orobanche reticulata Wallr. are discussed in this paper. On the Bér-hegy hill (Eastern Bakony Mts) the species was observed on a so far unknown host plant (Carduus hamulosus). Although the species usually flowers from May to July in Hungary, the observed individual was in full bloom in October, probably due to the extremely rainy year (2010). Another population of the species, found at Magyaralmás settlement in the foreground of the Vértes Hills, deserves attention because of its size. In early summer of 2020, individuals of O. reticulata appeared in a great quantity (several hundred ones) on a fallow land that was developed from a natural dry grassland having been ploughed in the previous year. In this case the local host plants were Carduus nutans subsp. leiophyllus and Carduus acanthoides. Some further records of the species from the Transdanubian Mts and the regions of Külső-Somogy and Mezőföld present new data in the Hungarian flora mapping program.

  This paper is the 10th in the series aiming to contribute with new distribution data to the maps published recently in Atlas Florae Hungariae. Distribution data of 686 plant species from 194 flora mapping units are published in this study, but all of them are listed in an electronic appendix. As a result of local surveys, more than 100 new species were found in a single flora mapping unit. Other “linear surveys” along the National Blue Trail revealed 142 new species in 10 flora mapping units in total. Among these, Carex strigosa is one of the most interesting taxa in the Bakony Mts. Previously published and new distribution data of this legally protected sedge species suggests that it is spreading from SW to NE within the Transdanubian Mts. Results from our survey shows that studying synanthropic habitats like frequently used hiking trails might provide a significant amount of new data points at the scale of Hungarian Flora mapping units. Moreover, similar studies might shed some light on the origins and migration routes (e.g. Illyrian and Dacian routes) of “native” species.
