Monitoring of the Apium repens population near Császártöltés (2006–2015)
1–8Views:186Detailed botanical surveys were carried out to monitor the population size of Apium repens in the Vörös-mocsár nature protection area (located in S Hungary, Császártöltés). We found a clear correlation between the water status and the land use type and management of the habitats and the size of the Apium repens population. Apium repens is a Nanocyperion-species, which simultaneously requires wet and open surfaces. Its population shrinks, becomes latent or disappears if its habitat dries out or any other radical transformation happens, like too much leaf litter, closure of the vegetation, or succession on the open peat surfaces. Proper management (water retention, extensive grazing, mowing, open peat surface) has a very positive effect on the populations in a short time, even within a growing season. The research was implemented within the framework of the National Biodiversity Monitoring System, in cooperation with the Kiskunság National Park Directorate.

The microscopic fungi of protected plant species in the Őrség National Park and the surrounding area (W Hungary)
187-211Views:67The paper deals with the study of microscopic fungi occurring on protected plant species of the National Park of Őrség and the surroundings. The survey includes both field observations and laboratory tests. The aim of the study was to identify the microscopic pathogen fungi living on protected plant species. Also spatial and temporal distribution, infection and damage rate of pathogenic fungi infections were determined for some protected plant species. Between 2002 and 2009 mycological research was conducted including 78 protected plant species and near to one hundred fungus species were identified on them. We provided data at the first time of microscopic fungi found on protected plants of Őrség.

Occurrence and habitat conditions of Gagea minima along the Sorok stream (W Hungary)
189–194Views:207Gagea minima (L.) Ker Gawl. is a Eurasian bulbous species. It occurs sporadically in Hungary, but so far only one current occurrence is known from the Western Transdanubia. In recent years, a large metapopulation has been found in a 15 km long section of the Sorok stream. Its habitat is the high sandy bank above the stream, where it lives mostly in nitrophilous vegetation under non-native tree species. Its long-term persistence in this secondary habitat may have been facilitated by its bulbs, which may have been regularly dispersed by periodic disturbance. Myrmecochory may also have played a role in the local establishment of subpopulations. A number of recently found populations indicate that data on the distribution of the species is still incomplete. The lack of data is probably due to its short flowering period and relative inconspicuousness. Gagea minima is considered a valuable relict species in the altered environment of the Sorok stream and its surroundings.

Contributions to the Atlas Florae Hungariae I.
101–115Views:262The main aim of the present work is to contribute with new data to the distribution maps published recently in Atlas Florae Hungariae. Occurrence data of 297 vascular plant taxa from 247 flora mapping quarter quadrates (CEU) are presented. This floristic paper is somehow unusual because besides the occurrence data of rare or sporadic taxa (e.g. Armoracia macrocarpa (Waldst. et Kit.) Kit. ex Baumg., Samolus valerandi L., Epipactis voethii Robatsch), frequent, but more or less underrepresented taxa (e.g. Ranunculus ficaria L., Viola kitaibeliana Roem. et Schult., Gagea villosa (M. Bieb.) Duby), as well as alien taxa (e.g. Cymbalaria muralis G. Gaertn., B. Mey. et Scherb., Potentilla indica (Andrews) Focke, Tragus racemosus (L.) All.) are also enumerated, since our intention was to fill the – sometimes evident – gaps in the Atlas. The name initials of the author(s) who actually found the given occurrence are presented in brackets at each record.

Sorbus udvardyana Somlyay & Sennikov in the eastern part of the Balaton Uplands
55-58Views:293Related 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.

Data on spreading cultivated species in Hungarian botanical gardens
62–78Views:378Our article provides data of 186 spreading cultivated taxa in Hungary. Among these, the spreading of 40 species in botanical gardens was not known until now. During our work, we examined the arboretums of Tiszakürt, Szarvas and Erdőtelek, the agrobotanical garden of Tápiószele (located in the National Centre for Biodiversity and Gene Conservation), the botanical garden of the Eszterházy Károly Catholic University in Eger and the De la Motte Castle Park in Noszvaj. We collected further data on the lately identified Cardamine occulta and the spreading Veronica peregrina taxa, which spread mainly through plants sold in pots. Besides the already known two Juglans species, we found four new potentially spreading ones from the family of Juglandaceae (Carya cordiformis, C. ovata, Juglans cinerea and J. microcarpa). We also found seedlings and saplings in the case of all the investigated Abies species. We found the seventh Hungarian occurrence of Ludwigia grandiflora in the artificial lake of the Arboretum of Szarvas. The quantity of new occurrences reported in this paper highlights the need for further research in living collections in Hungarian botanical gardens.

Contributions to the Atlas Florae Hungariae IX.
253–256Views:332The current paper is the 9th in the series aiming to provide new data to the distribution maps of Atlas Florae Hungariae. Data of 734 vascular plant taxa (from 222 flora mapping quadrats) are presented in this study. The new localities are spread across nearly the entire country; however, most of the data are from the North Hungarian Mts, the northern part of the Danube-Tisza Interfluve, the southern edge of Hanság, alongside River Maros and the Hortobágy. Altogether, 1632 new data records are presented in this paper. The list mainly contains rare and locally important native species, as well as species with uncertain native/alien status (e.g. Allium ursinum, Chamaecytisus triflorus, Cotoneaster niger, Cyperus pannonicus, Elatine triandra, Eleocharis acicularis, Eleocharis ovata, Erodium hoefftianum, Geranium lucidum, Globularia punctata, Hippuris vulgaris, Hottonia palustris, Lindernia procumbens, Marrubium vulgare, Ononis pusilla, Orobanche bartlingii, Orobanche cernua, Pisum elatius, Polycnemum majus, Polygonum graminifolium, Ribes nigrum, Schoenoplectus triqueter, Verbascum ×denudatum, Verbascum ×vidavense, Viola canina subsp. schultzii). We report new localities of expanding alien species (e.g. Amaranthus deflexus, Artemisia annua, Euphorbia maculata, Helminthia echioides, Hordeum jubatum, Impatiens glandulifera, Ipomoea purpurea, Mahonia aquifolium, Panicum riparium, Robinia viscosa, Rudbeckia hirta, Veronica peregrina, Yucca filamentosa) and mention a few rare, successfully “surviving” alien plants with nature conservation value (e.g. Acorus calamus, Monochoria korsakowii). Moreover, occurrences of common plants are presented when new to the Atlas Floraea Hungariae (e.g. Bromus hordeaceus, Symphytum officinale, Vicia tetrasperma).

Occurrences of Kievan nettle (Urtica kioviensis) in the South Nyírség (East Hungary)
126–131Views:266So far, only one herbarium data and one flora mapping data on Kievan nettle (Urtica kioviensis Rogow.) has been known from the Southern Nyírség. Since 2004, the species has been detected in 14 flora mapping quadrats. Its data were also collected in winter because its habitats are more easily accessible on ice, its overwintering shoots are more noticeable, and they are strikingly morphologically different from the great nettle (Urtica dioica L.). Typical habitats were willow carrs (Calamagrosti-Salicetum cinereae), reeds (Phragmitetum communis), rush-beds (Typhetum latifoliae, Typhetum angustifoliae), tufted sedge communities (Caricetum elatae) and tall sedge meadows (mainly Caricetum acutiformis). The largest stocks live in reservoirs in secondary habitats. A significant part of the stocks is located in the wide valleys of the main watercourses in the area.

Botanical comparison of man-made landforms in the Nagykunság and Nagy-Sárrét regions (E Hungary)
65-76Views:213Loess 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.

Results of the Vincetoxicum pannonicum population survey (2001–2019)
9–18Views:1016The Pannonian swallow-wort (Vincetoxicum pannonicum (Borhidi) Holub) is endemic to the Pannonian biogeographical region, occurring only in the Buda and Villány Mts in Hungary. Current distribution and population size of this rare plant species is surveyed. The species is recorded from the following localities: Budajenő: Községi erdő, Budaörs: Szekrényes, Kő-hegy, Odvas-hegy, Szállás-hegy, Út-hegy, Páty: Fekete-hegyek; Nagyharsány: Szársomlyó. According to our research, the total number of individuals is around 3550. The largest populations were found at Községi erdő (Budajenő), Szállás-hegy (Budaörs) and Fekete-hegyek (Páty). In the Villány Hills (Mt Szársomlyó) ca 50 specimens were counted. The peak flowering period of Vincetoxicum pannonicum was observed between 20th and 29th of May.

Contributions to the algal flora of a recently-formed peat moss bog near Kőszeg (W Hungary)
113–130Views:388The 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.

Rare vascular plants and fungi of Zalaegerszeg-Botfa (W Hungary)
95-103Views:205The present study reports the occurrence data of 3 macrofungi and 47 vascular plant taxa, collected in Zalaegerszeg-Botfa between 2006 and 2017. These new data provide valuable additional information to the distribution map of the studied species. The spatial and abundance information of both protected and non-protected species can contribute to the future biodiversity monitoring activities in order to asses and mitigate the human impact upon natural plant communities and semi-natural habitats.

Data to the distribution and nature conservation of Sorbus bakonyensis
229-233Views:1330Sorbus 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.

Floristical data from abandoned vineyards of Cserhát Hills
260-266Views:62The results of floristic researches in abandoned vineyards of Cserhát Hills (Northeastern Hungary) between 2007 and 2014 are presented along with an account of relevant floristic literature and specimens of the Herbarium Carpato–Pannonicum Collection of the Hungarian Natural History Museum. Data of protected species and locally or generally rare ones are presented. Occurrences of Equisetum × moorei, Hesperis sylvestris, Gentiana cruciata, Scabiosa canescens, Campanula macrostachya, Carlina acaulis, Centaurea indurata, C. stenolepis, Epipactis atrorubens and Orchis ustulata subsp. aestivalis are especially significant. Some new localities of the following species are also emphasized: Pulsatilla grandis, Sorbus domestica, Centaurea scabiosa subsp. sadleriana, Orchis militaris, O. × hybrida, Ranunculus arvensis, Rapistrum perenne, Chamaecytisus virescens, Ch. austriacus, Hippocrepis comosa, Euphorbia salicifolia, Thymelaea passerina, Senecio erucifolius.

Reseda inodora Rchb. in the Tiszántúl region (East Hungary)
48-54Views:160On 14 August 2012 a small population of Reseda inodora was found in Hegyes-halom kurgan within the administrative boundaries of the town of Mindszent (Csongrád County, CEU: 9487.3). The approximately 50–100-stem-large population of the species lived on the edge of the kurgan, on the sparsely vegetated, weedy fieldmargin. On 19 July 2014 this species has turned up again in this area. In this case it was the biggest amount with some hundred stems and was located on the edge of the mound, which is in the verge of the neighbouring corn field. The Reseda inodora is a new recent protected vascular plant species within the operation area of the Körös–Maros National Park. We propose this species to be included in the regional red list in the category of „CR” (Critically endangered). Other rare weed or pioneer species (Caucalis platycarpos subsp. muricata and subsp. platycarpos, Erodium ciconium, Lappula squarrosa, Melica transsilvanica, Papaver hybridum) have already been found in Hegyes-halom kurgan in the last few years. The results show the importance of kurgans not only in the conservation of natural steppe, loess wall vegetation and steppe shrub species, but in the survival of some endangered weed species as well (e.g. some rare archaeophytes).

Distribution and flora of areas with alkaline and saline soils in the Mezőföld, Hungary
39-61Views:237Areas with alkaline and saline (solonetz and solonchak) soils occupy substantial areas in the westernmost, Transdanubian part of the Great Hungarian Plain (Mezőföld). To this date, the flora and vegetation of only two localities have been studied in some detail, while the rest has remained largely unknown in this respect. In this paper, I provide brief descriptions of these little-known areas and present a list of halophytes with distribution data from the last 17 years. The names of the plants are followed by the name of the township and the geographical location where the plant was found, the code of the grid cell of the Central European Flora Survey grid that includes the location, and in selected species, the year when the species was first recorded. The list is arranged in alphabetical order irrespective of taxonomy. The occurrence data indicate that the floras of these saline-alkaline areas represent only subsets of, but in combination are almost identical to the overall flora of similar habitats in the Sárvíz plain.

Lajos Felföldy: a prominent Hungarian botanist and hydrobiologist
3–25Views:213Lajos Felföldy (1920–2016) was one of the most versatile and open-minded Hungarian biologists. He began his scientific career as a student of Prof. Rezső Soó. Between 1938 and 1946 he participated in geobotanical studies in University of Debrecen and Kolozsvár (Cluj-Napoca, Romania). He contributed with important achievements to the development of several biological disciplines. His pioneering study on the effects of air pollution on epiphytic lichens (1942) was among the firsts in the world. He described Hemitherophyte life-form as a discrete unit within Raunkiaer's plant life-form system (1942). He was a pioneer in the cytological (caryological) study of wild vascular plant species in Hungary (1947–1949). His results regarding to primary production of freshwater algae and algal culture (1958–1960) were in leading edge. In 1972 he founded and until 1990 edited the Hungarian series entitled ‘Vízűgyi Hidrobiológia’. Books of this series aimed to publish identification keys of freshwater taxa. These books were proved to be decisive and useful tools for Hungarian hydrobiologists in biological classification of brooks, streams, rivers and different types of stagnant waters. Between 1934 and 2009 he collected more than ten thousand herbarium sheets. After his retirement, he dealt with the revision of the herbarium material of Department of Botany in Hungarian Natural History Museum and Botanical Garden of Eötvös University (Budapest). He participated in the preparation of the New Hungarian Herbal. His scientific work was characterised by deep humility for nature, which was founded on strong theoretical and practical background.

Online distribution atlas of the Hungarian vascular flora (Atlas Florae Hungariae): Homepage structure and prospects of database building
238–252Views:514In December 2018 the online Distribution atlas of vascular plants of Hungary (Atlas Florae Hungariae) was published. The database was built from more than 1 million data records. It mainly contains data from the Hungarian Flora Mapping Programme, but herbarium and literature data were also processed. Maps of species richness illustrate the taxonomic diversity of biogeographical areas and shows the differences of survey quality. After the Flora Mapping Programme ended, between 2016 and 2019, additional data from scientific articles were processed. 25% of new data originated from the article series “Contributions to the Atlas Florae Hungariae” in the Kitaibelia journal, which significantly broadened the distribution of some species. Records of Mesophile forest species (e.g. Allium ursinum, Dryopteris dilatata) increased, as well as records of weed species (e.g. Euphorbia maculata, Senecio vernalis) which can be attributed to their natural spreading. The most important future tasks are to create a reviewed list of taxa and extend data records with an attribute table containing all additional information. Until now the database website is presented only in Hungarian (http://floraatlasz.uni-sopron.hu). Registration is available for anybody, after sending a request via e-mail (atlas.florae.hungariae@uni-sopron.hu). There are different options (excel file by e-mail or online web form) on how to upload floristic data for registered users. Data is only accepted if required information (name of taxa, date, data publisher, settlement, CEU code) is filled out. Each record of uploaded data is revised by the website administrator and taxa specialists. The English version of the webpage will be available in the near future.

Contributions to the Atlas Florae Hungariae X.
101–106Views:392This 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.

Turkey oak forests on sand (Fraxino orno-Quercetum cerridis) in Vértesalja (Hunga-ry)
34–57Views:167Here we evaluate the phytosociological characteristics of the turkey oak forests on sand (Fraxino orno-Quercetum cerridis) found at the northern foothills of the Vértes Hills, Hungary. Using the traditional Braun-Blanquet method, 20 vegetation samples were collected and compared with turkey oak forests growing in similar ecological situations in other parts of the country. The traditional and multivariate analyses showed that our samples were quite different from the compared forests, and only the forests in the Bakonyalja and the Pilis Mts showed some similarity with the compared forests. Our samples had the lowest proportion of Quercetea pubescentis-petraeae species among the compared forests, and the highest proportion of specialists (Corydalis pumila, Daphne laureola, Doronicum hungaricum, Lychnis coronaria, Physocaulis nodosus, Primula veris, Scutellaria columnae, Sorbus domestica and Veratrum nigrum). The samples were well separated from the compared forests and formed a distinct group.
