Data on the occurrence of Ducellieria chodatii in West-Hungary
3-10Views:406During an algal survey of the peat moss transition bog near Kőszeg, in the Alsó-erdő, which started nearly three years ago, a new, previously unregistered species, Ducellieria chodatii (Ducellier) Teiling, was found in spring 2022. As a pine pollen parasite, its appearance can be linked to the recent increased pollen production in the surrounding pine and pine-mixed stands. Both morphologically and in terms of the environmental conditions of the biotope, the results of the studies were largely consistent with previous relevant data in the literature. Differences from previous literature are the lower spatial depth of the habitat and the high conductivity of one of the sample sites. All this knowledge, together with the accompanying photographs, is intended to serve as a contribution not only to research on the native occurrence of D. chodatii, but also to research on the morphological, taxonomic characteristics and ecological requirements of the species.

The herbarium of Debrecen University (DE) I. The “Rezső Soó Herbarium”
142-155Views:166The paper introduces the herbarium of Debrecen University (DE). All specimens of the herbarium were documented by digital photographs, and all data from the labels were entered into an Excel spreadsheet. The largest collection of Herbarium DE, the “Soó Rezső Herbarium” (abbreviation: SRH) consists of ca. 38.000 specimens from almost all European countries, but mainly from Hungary and the neighbouring countries. Most of the specimens originate from Hajdú-Bihar, Pest, Győr-Moson-Sopron, Borsod-Abaúj-Zemplén, Veszprém and Szabolcs-Szatmár-Bereg counties. The SRH stores a considerable amount of original/authentic specimens collected by Hungarian botanists, primarily by Rezső Soó and his followers, as well as Sándor Polgár. The most rapid growth of the SRH took place in the first half of the last century (1930–1950). By contrast, the collection was practically not developed between 1955 and 2000. After the millennium it started to grow again. Data on the most substantial part of the SRH covering native plants collected in the present-day Hungary are summarized in Electronic Appendix 1. (incl. taxon name, settlement, collecting date, collector, file name of documentary photograph).

Data to the distribution and nature conservation of Sorbus bakonyensis
229-233Views:1296Sorbus 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.

Distribution of Pseudoleskea saviana (De Not.) Latzel in Hungary
272–285Views:136Three new localities of the moss species Pseudoleskea saviana (De Not.) Latzel were discovered in the Börzsöny Mts in the administrative district of Perőcsény village, North Hungarian Mountains (Nagy-Hideg-hegy, near Hangyás-bérc, in the col between Csóványos and Magosfa). Small populations were found on shaded andesitic boulders in mixed deciduous forests. Up to the present, only old collections of the species were known from a single locality in the Mátra Mts; therefore, the red list status was data deficient. The morphological distinction of P. saviana from P. incurvata, its closely related congener also reported from Hungary is not always exempt from difficulties. However, the presence (P. saviana) or absence (P. incurvata) of a central strand in the stems, the shape of mid-leaf cells (P. saviana: more elongated, 3–4 times as long as wide; P. incurvata: at most twice as long as wide), as well as the shape of the outer basal cells (P. saviana: quadrate or shortly rectangular; P. incurvata: transversely elongated) seem to be reliable distinctive features.

Data on the occurrence of alien plants in Western Transdanubia (Hungary)
185–188Views:760In his publication the author provides data on the occurrence of 11 alien species in Western Transdanubia. Three of these species (Euphorbia maculata, Euphorbia peplus, Muscari armeniacum) were observed to have spread rapidly in the past decade. It can be concluded that 4 species (Artemisia annua, Crocus banaticus, Polycarpon tetraphyllum, Veronica filiformis) have reached a state which is close to naturalization, while the other reported species (Euphorbia lathyris, Senecio inaequidens, Silybum marianum, Veronica peregrina) are casual in this region at present.

The flora of Bolondvár (Central Hungary, Colocense)
133-141Views:87A 0.26 km2 sized Natura 2000 area called Bolondvár, located in Central Hungary, near the village Mezőfalva was studied. It is used regularly as a meadow or sometimes as a pasture. Floristic data were collected between 2010 and 2013. The total number of taxa recorded was 362. The species diversity was high compared to other places of Hungary. There were 11 protected (e.g. Ajuga laxmannii, Astragalus asper, Cirsium boujartii, Inula germanica) and numerous locally rare species (e.g. Hieracium densiflorum, Lavatera thuringiaca, Orobanche lutea, Veronica austriaca).

Contributions to the flora of railway-side pioneer habitats on Tiszántúl region
86–101Views:400Verges have considerable importance to preserve diversity in arable landscape. The modernized railway embankments are a great surface to the spread of native pioneer or adventive (invasive) plant species. The new data are about the flora of railway embankments mainly from Tiszántúl region. I present some species found on railway verges (e.g. Equisetum ×moorei, Equisetum ramosissimum, Lycopsis arvensis, Euphorbia maculata, Lepidium densiflorum Tragus racemosus, Vulpia myuros). An especially important new data is the refinding of Galium humifusum in Hungary. Locally non-native and adventive species can use the blanketing materials (sand or gravel) of railway embankments as dispersal corridor and colonize them. The railwayside habitats could contribute to the conservation of rare native pioneer species.

The herbarium of the Botanical Garden of Eötvös Loránd University (BPU)
55–59Views:207The paper introduces the herbarium of Eötvös Loránd University (BPU), currently stored at the Botanical Garden of the University, according to its state in the year 2013. The BPU herbarium consists of ca. 16 000 specimens the relevant data of which have been organised into an OpenOffice Calc spreadsheet database. The specimens were collected in 16 European countries, mainly in the current territory of Hungary (80%), Romania (12%) and Slovakia (5%). Other countries are represented with very few specimens. The vast majority (ca. 70%) of the Hungarian specimens were collected in Pest, Veszprém, Borsod-Abaúj-Zemplén, Hajdú-Bihar and Szabolcs-Szatmár-Bereg counties. Although the gatherings cover a century and a half period of time, the most rapid growth of the collection took place from the 1930s to the 1960s. The most prolific collectors were Rezső Soó and his followers: Lajos Felföldy, Tibor Simon and Szaniszló Priszter. Felföldy and Simon enriched the collection through more than 60 years. Data on the native plants collected in the present-day Hungary are summarized in Electronic Appendix 1. (incl. taxon name, settlement, collecting year, collector, file name of documentary photograph).

Data to the flora and vegetation of Hungary III.
197-206Views:149We report the occurrence data of 44 vascular plant taxa collected at various localities in Hungary (mainly the Danube–Tisza Interfluve and South Transdanubia) during floristic, vegetation and ecological field surveys between 2016 and 2018. Of the species in the present article, 27 are protected or strictly protected. In the paper we focused on plants that are rare regionally (e.g. Botrychium lunaria, Polystichum aculeatum) or in the whole country (e.g. Ophrys oestrifera, Ranunculus psilostachys), as well as on plants that occurred in unusual habitats (e.g. Corydalis solida). We also included new localities of weedy species, some of which (e.g. Opuntia humifusa, Sporobolus cryptandrus) may present nature conservation threats.

On the former occurrence of Calla palustris in Hungary
200-210Views:1700The origin of a more than 150 years old herbarium specimen of Calla palustris L. stored in JPU is reconsidered in this study. According to the information on its label, the specimen was collected in 1856 at Lake Velence, close to Székesfehérvár city (central Hungary). Some Hungarian botanists are skeptical about the authenticity of this record. Based on the current occurrences of some remarkable swamp species (e.g. Carex pseudocyperus, Liparis loeselii, Sphagnum spp.) and habitat types (e.g. willow carrs and swamp forests) at the lake, as well as the habitat preference of bog arum, there is no reason to question the former occurrence of the species here or even in other Hungarian localities. The content and accuracy of the examined voucher meet the expectations of floristic data. However, in the absence of recent data the species can be considered extinct from Hungary.

Taxiphyllum densifolium (Taxiphyllaceae) and other rare bryophytes of the Mecsek valleys (SW Hungary)
3-16Views:88In this paper, we deal with threatened and/or legally protected bryophytes found in the shady, forested valleys of the Mecsek Mountains, which are rare in national and/or local terms. Taxiphyllum densifolium, a rare moss in Europe has stable colonies with sporophytes in two valleys. This study is the first to describe the spore characteristics of this species. The previously considered unique and legally protected Rhynchostegiella teneriffae is nowadays so widespread in the Mecsek that it can no longer be considered a vulnerable species (VU) in Hungary. We present the first population of the legally protected Neckera pennata in Tolna county, and we also report on the recent, unusual occurrence of the data-deficient (DD) Fossombronia wondraczekii. We also list new populations of three other endangered (EN) species, Blindiadelphus recurvatus, Palustriella commutata and Porella arboris-vitae. Several vulnerable (VU) taxa such as Blepharostoma trichophyllum, Porella cordaeana, Sciuro-hypnum flotowianum, Seligeria pusilla, as well as new occurrences of near threatened (NT) mosses such as Microeurhynchium pumilum (with sporophytes), Phaeoceros carolinianus are documented. In addition, the data on Rhynchostegium rotundifolium in Jakab Mountain, which has not been recorded for more than 50 years, is confirmed. The difficulties of differentiating Hygroamblystegium species are briefly discussed.

Contributions to the flora of Baranya and Tolna counties III.
39-50Views:128During the last four years (2014–2017) that have passed since my last publication, I have been collecting 25 000 new floristic data for the territory of the Danube–Drava National Park. The most valuable and interesting records of 116 taxa are presented here, e.g. those of the strictly protected Digitalis ferruginea and Paeonia banatica, and the protected species Polystichum lonchitis, Dryopteris affinis, Doronicum orientale, Helleborus dumetorum, Corydalis intermedia, Spiraea media, Veratrum nigrum. New records of not protected but rare species, such as Lycopsis arvensis, Silene dichotoma, Teucrium botrys, Thladiantha dubia, Vicia lutea, Hypochoeris radicata are also enumerated. Some curiosities are mentioned as well, including the sizes of the biggest (and probably the oldest) Crataegus monogyna, Hedera helix, Ruscus hypoglossum and Ruscus aculeatus individuals that were found during my field work.

The flora of the Sárvíz plain (Mezőföld, Hungary)
207–226Views:311In this paper, I present chorological data on the plants growing on the alluvial plain of the Sárvíz river in eastern Transdanubia, Hungary. Species characteristic of reed and sedge marshes, salt lakes and alkali flats, as well as remnants of hardwood forests and mesoxeric grasslands are listed in the enumeration. Since 2004, I have confirmed the occurrence of 50 species previously not recorded in the study area. Here, I report the species names, followed by data on the locality: the name of the township, the geographical name of the locality, and the code(s) of both grid systems, the Central European Flora Mapping System (CEU) and the UTM. Sites where I observed or collected the species after 2004 are in bold. Names of species new to the study area are underlined.

Distribution of Campylopus introflexus (Hedw.) Brid. in Hungary
212-219Views:85Based on field work data collected in 2013–2014, the authors generated a map of the current distribution of Campylopus introflexus for Hungary. Besides the coordinates and geographic name of the localities, an estimated size of the population, the type of habitat and substrate, the co-occurring moss species and affected vegetation types were also recorded. Altogether, 18 stands were found in 8 geographical regions of Hungary, in some cases Campylopus introflexus was found to be a new species record for the moss flora of the respective region (e.g. Dunántúli-dombság, Nyugatmagyarországi peremvidék). In addition to the pine plantations from where it was detected formerly, the mixed deciduous-coniferous forests, the acidophilous oak woodlands and man-made habitats were found to be also proper habitats for this moss taxon. Earlier data mainly originated from pine deadwood, the recently discovered stands were found on acidic soil surfaces. The most important cooccurring moss species were the followings: Hypnum cupressiforme, Polytrichum piliferum, P. formosum, Pohlia nutans and Ceratodon purpureus. Campylopus introflexus had prominently high coverage in the acidophilous oak forests of the Mecsek Mts, where it occurs on acidic sandstone covered with a thin debris of the bedrock. This neophyte moss is widely distributed in Hungary, and has stable populations. Further expansion is expected in the subatlantic and submountain regions of the country, and in regions characterised by acidic soils and pine plantations.

Contributions to the flora of kurgans in the Middle Tisza region
94–105Views:513Kurgans are ancient burial mounds built by nomadic steppic cultures. Embedded in the heavily transformed landscapes of the Carpathian Basin they often serve as last refuges for rare and endangered plant species. In our paper we publish floristic data collected on 82 kurgans located in the area of the Hortobágy National Park Directorate. Our dataset covers 64 CEU quarter quadrates, and the territory of 45 settlements. We provide data on 39 taxa that are either protected (e.g. Anchusa barrelieri, Centaurea solstitialis, Ranunculus illyricus and Phlomis tuberosa) or regionally rare (e.g. Aegilops cylindrica, Astragalus austriacus, Glaucium corniculatum and Trifolium diffusum). Our records demonstrate that kurgans have a vital role in maintaining the populations of rare and endangered grassland species even in transformed landscapes.

Data to the flora and vegetation of Hungary II.
104–113Views:167We report the occurrence data of 45 vascular plant taxa collected at various localities in Hungary (Duna–Tisza Interfluve, Tiszántúl and South Transdanubia) during floristic, vegetation and ecological field surveys mostly between 2013 and 2016. Many of these plants are included in the ’Red list of the vascular flora of Hungary’ (e.g. Astragalus dasyanthus, Erodium ciconium and Lotus angustissimus). We primarily focused on the occurrence of rare plants (e.g. Apium repens, Epipactis bugacensis and Trifolium strictum), plants that appeared in unexpected places (e.g. Medicago arabica, Polypodium vulgare and Polystichum setiferum) or have a phyto-geographic importance (e.g. Piptatherum virescens, Ranunculus psilostachys and Tamus communis).

Distribution and flora of areas with alkaline and saline soils in the Mezőföld, Hungary
39-61Views:215Areas 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.

New occurrences of Ranunculus strigulosus in East Hungary
3–8Views:330The exact distribution of Ranunculus strigulosus Schur is poorly known in Hungary. Current occurrence data of the species mainly from Békés county and only one archive data from the Nyírség region, from the 1920s were known. This study presents eleven newly discovered occurrences in East Hungary. Populations were found in wet meadows, forest glades and poplar plantations. Nine of these populations are located at the southeastern edge of the Nyírség region and most of them are quite small. Three larger population were found in Nyírábrány, Álmosd and the Tócó Valley between Debrecen and Hajdúböszörmény. One of the newly discovered populations provides a new contribution to the flora of Bátorliget Marsh and Fen-wood NCA. Some morphological characters (hairs on the stem and the leaves, shape of the leaves developed before and after the mowing) are also discussed.

Occurrence and habitat conditions of Gagea minima along the Sorok stream (W Hungary)
189–194Views:136Gagea 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.

Rare vascular plants and fungi of Zalaegerszeg-Botfa (W Hungary)
95-103Views:188The 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.
