  • Data on the pioneer vegetation of the Lake Velence
    203–208
    Views:
    144

    Lake Velence is one of Hungary's largest saline lakes. Part of its natural dynamics is that certain parts of the lake bed regularly dry out, providing pioneer surfaces suitable for the emergence of plants of the mudflats and drying (saline) ponds. During the particularly dry year of 2022, the water level was per­manently and significantly low, allowing to study the vegetation of the dry lake bed. In the first half of the last century, the natural vegetation of the lakeshore (including salt steppes) was studied, but there are very few records of the pioneer species of the lake bed. The salt steppes around the lake have now largely declined, but due to low water levels, some of their characteristic species are still present in the lake bed (though, usually in low number of individuals). Examples include Crypsis aculeata, Cyperus pannonicus, Suaeda pannonica, the once abundant Suaeda prostrata, and the previously rare Crypsis schoenoides and Spergularia salina. Spergularia maritima was once widespread but currently not found in the lake bed. Although, Schoenoplectus litoralis is not a member of the ephemeral vegetation, but is a characteristic plant of the littoral zone of Lake Velence. This species probably appeared therein the middle of the last century and is currently spreading.

  • Contributions to knowledge on the distribution of nine adventive or invasive algae species in Hungary

    Hungarian records of nine adventive or invasive algae [Didymosphenia geminata, Nitzschia closterium, Reimeria sinuata, Navicula schroeteri, Pleurosira laevis (Bacillariophyceae); Pediastrum simplex (Chlorophyceae), Cylindrospermopsis raciborskii, Cuspidothrix issatschenkoi, Sphaerospermopsis aphanizomenoides (Cyanobacteria)] are presented. Navicula schroeteri Meister is a new species for the Hungarian flora. Although the observed distribution patterns of these species were very different, the increasing frequency of their appearance indicates significant effect of climate change on abiotic environment of inland waters, such as the increase in water temperature, increase in salt concentration, and eutrophication. The significance of continuous biomonitoring is emphasized, which, through the recognition of natural and human-induced changes in species composition of algae, or the appearance and rapid expansion of non-indigenous species, can detect environmental changes of inland waters.

  • Vaccinium microcarpum (Turcz. ex Rupr.) Schmalh. in Hungary

    The plant that was reported as Vaccinium oxycoccos L. from the Nyírjes-tó (Sirok village, NE Hungary) in 1994 was subsequently (1999) identified as Vaccinium microcarpum (Turcz. ex Rupr.) Schmalh. by the first author of this article. To substantiate this identification morphometric data were collected and analysed from Vaccinium specimens occurring in the Sphagnum dominated mires of Nyírjes-tó (Sirok vilage) and Nyíres-tó as well as Báb-tava (Bereg-plain) in September 2016. Field photographs taken previously at the localities of Bereg-plain were also used for identification. The leaves of the Sirok plants are smaller, ovate-triangular, i.e. widest near base. The ovate-elliptic bracteoles are inserted on the basal third of the glabrous pedicels. The flowers are solitary, and have dark pink corollas and hairy filaments on the whole abaxial surface. The fruit is pyriform. In contrast to the Sirok plants, those of the Bereg-mires have clearly larger and ovate-elliptic leaves. The filiform bracteoles are inserted on the middle third of the minutely hairy pedicels. The whitish flowers are grouped in clusters of (2)–3–4–(5), i.e. they form an inflorescence. The filaments are hairy only on the margins of the abaxial surface. The fruit is globular. The statistical analysis confirmed that the Sirok plants belong to Vmicrocarpumwhereas the Bereg-plain plants represent V. oxycoccos.

  • Distribution of Calamagrostis stricta (Timm) Koeler in the Southern Nyírség (E Hungary)

    This study presents the current distribution of narrow small-reed (Calamagrostis stricta (Timm) Koeler) in the southern part of Nyírség (E Hungary). Beyond the efforts to confirm previously known occurrences, a high number of potential habitats were surveyed. Field work was carried out from late autumn to early spring taking advantage of the better perceptibility of dry foliage. The species was detected in 43 localities inside the boundary of 15 settlements, which considerably exceeded our expectations. Although most of the populations were quite small, in some cases their extent reached over 1000 m².  Populations around the settlements of Penészlek, Fülöp and Nyírábrány were the most frequent and the largest in size. The endangered status of the species is caused by the insufficient water supply of suitable habitats in the region. Besides habitat change, desiccation can also amplify the effect of anthropogenic disturbances (e.g. ploughing, fishpond development), which poses a further threat to populations.

  • Data to the distribution and nature conservation of Sorbus bakonyensis
    229-233
    Views:
    1277

    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.

    New localities of 4 rare taxa are presented from Eastern Hungary. The species are new for the flora of particular floristical regions, specifically: „Eupannonicum”: Polystichum braunii; „Crisicum”: Aphanes arvensis; „Samicum” and „Nyírségense”: Agrimonia procera. Three new localities of the alien species Montia linearis in Hungary are presented. This species is still very rare in Europe, reported only from Poland, Denmark and Hungary.

    In 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.

    In 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.

  • Data to the flora and geobotany of Kisalföld (Lesser Plain) region, NW Hungary

    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 ramosusHypericum dubiumLathyrus 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 rivulareDryopteris dilatataEquisetum telmateia), loess-connected species mainly on the Moson Plateau (Agropyron cristatumAllium atroviolaceumEuphorbia salicifoliaViola ambigua); and occurrences of species on sandy soils near the Lake Fertő (Draba nemorosaStipa pennata).
    • We explained the known localities of several salt tolerant species (e.g. Carex divisaCrypsis alopecuroidesJuncus maritimusLimonium gmeliniiSuaeda 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 tataricumBetula pubescensFraxinus ornusQuercus petraea, Salix pentandra).
    • We discussed the regional nature conservational status of several protected and/or threatened species (e.g. Allium carinatumAllium suaveolensCarex strigosaHottonia 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).

  • Contributions to the escaped, naturalised and potentially invasive species of the Hungarian adventive flora

    In this paper we compiled data on 157 Hungarian adventive plant species – of which 65 had not been reported from the country previously – from 47 settlements of Transdanubia and the Great Hungarian Plain. These taxa are rare, interesting or not included in the most recent list of the Hungarian neophyte species. The list includes data about many rare, occasionally escaping species (e.g. Lagurus ovatus, Salvia coccinea), taxa considered incapable of reproduction under the recent climatic conditions of the Pannonian Basin (e.g. Cupressus sempervirens, Punica granatum) or naturalised plants that may become invasive in the future (e.g. Celtis sinensis, Lonicera japonica). In the outlook we highlighted some special urban habitats (e.g. private and botanical gardens) and practices (e.g. public green space management) that endanger the native flora. We also describe their role in promoting the appearance and the expansion of alien plant species, and processes (e.g. laurophyllisation, spread of thermophile species) that will become increasingly common in the future as a result of climate change.

  • On the former occurrence of Calla palustris in Hungary
    200-210
    Views:
    1674

    The 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.

  • Flowering phenology and distribution pattern of Lizard Orchids (Himantoglossum)

    Hybridization is very rare between the species of Himatoglossum genus, despite the fact that it is common in other orchid genera. The reasons for this can be the lack of overlapping distribution areas or the different flowering period of the species. In the paper distribution and flowering data of Himantoglossum species are presented from herbarium sheets or references (sources paper-based or internet). We collected 1001 precisely dated flowering records of 12 species. In case of 6 species (H. adriaticum, H. caprinum, H. comperianum, H. hircinum, H. jankae, H. robertianum) we had sufficient records to calculate the average flowering day and blooming length. According to the collected data the distribution of the species are overlapping except for H. formosum, H. galilaeum and H. metlesicsianum. Studying 55 species pairs, insignificant differences in blooming time were only at 21 species pairs, among them only 5 (H. comperianum - H. caprinumH. montis-tauri - H. comperianum, H. hircinum - H. adriaticumH. montis-tauri - H. caprinum és H. jankae - H. calcaratum) have overlapping distribution area. Data on hybridization could be found only at three species pairs among them. From the results we can conclude that in the case of Himantoglossum genus the rarity of hybridization is mostly due to the phenological isolation.

  • Escaping of Euphorbia myrsinites from cultivation in Eger (E Hungary)

    Euphorbia myrsinites L. (Euphorbiaceae) is a well-known ornamental plant with native dis­tribu­tion around the Mediterranean Basin, the Black Sea, the Caucasus region and Minor Asia. Its es­cape from cultivation and its naturalization in Western and Central Europe as well as in North America was reported in many cases. In Hungary, the casual escape of E. myrsinites has been documented more than fifty years ago and new observations were recently reported from different regions of the country. Here, I discuss a new record of the species from the town of Eger (E Hungary). The obtained data allow considering E. myrsinites as a locally naturalized species in the flora of Hungary. According to standard­ized criteria, the species may be able for local invasions too, but further observations are needed to accurately determine its present status in Hungary.

    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.

    In this paper, we presented the results of our floristic survey in West-Hungarian region. The data were collected between 2005 and 2015 and supportted with herbaria or photo-documentation. This paper reports new floristic data of 98 taxa from West-Hungary with altogether 172 field-collected data records. In the survey we focused on little-known taxa with a phyto-geographic importance. For some taxa we checked the herbarium specimens of Savaria Museum and Natural History Museum of Budapest. During our fieldwork we recorded 8 species new to W-Hungary, including 3 species considered to be native to the region [Oenanthe banatica Heuff., Koeleria pyramidata (Lam.) P. Beauv., Polycnemum majus A. Braun.]. Almost all of the recorded species are regarded as indigenous plants, many of them has nature conservation importance, thus, their monitoring are highly advised. We found new localities of many species which of high importance for plant geography describing their current distribution. Most of the recorded species occur in natural or semi-natural habitats, but some taxa were found in synanthropic habitats and extensive arable lands.

    This paper reports new floristic data of 207 taxa. Data collected between 2005 and 2015; originated from the central part of the floristic region ‘Crisicum’ (i.e. the E part of the Great Hungarian Plain), which is a currently poorly studied area of Hungary from a floristic point of view. The paper reports occurrence localities for some rarities such as Asplenium trichomanes, Marsilea quadrifolia, Sisymbrium polymorphum, Viola stagnina, Gentiana pneumonanthe, Elymus elongatus, Montia fontana subsp. chondrosperma, Ranunculus rionii, Ranunculus illyricus, Myagrum perfoliatum, Sedum caespitosum, Vicia biennis, Dorycnium herbaceum, Oenanthe banatica, Peucedanum cervaria, Echium italicum, Digitalis lanata, Valerianella rimosa, Craex buekii, Cephalaria transsylvanica, Cyperus pannonicus.

    Kurgans 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 barrelieriCentaurea solstitialisRanunculus illyricus and Phlomis tuberosa) or regionally rare (e.g. Aegilops cylindricaAstragalus austriacusGlaucium 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.

  • Contributions to the algal flora of a recently-formed peat moss bog near Kőszeg (W Hungary)

    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.

    The botanical and ethnobotanical studies of PÉNTEK & SZABÓ (1985) were repeated after 30 years, during an ethnobiological summer school held in Kalotaszeg region (Romania), in Apuseni Mountains. However, our intensive floristical researches focused only on two villages (Sztána and Zsobok). A list of the observed taxa and their frequency values are presented. Of the 747 taxa 52 are new to the narrow region. 74 species reported formerly from here were not found by us. The disappearance of some taxa (e.g. Crepis praemorsa, Conringia orientalis, Lolium temulentum) are probably due to changes in agricultural land use methods. The spread of a few new invasive species (e.g. Ambrosia artemisiifolia, Galinsoga ciliata, Senecio vernalis) as well as the presence of some floristically interesting species (e.g. Centaurium pulchellum, Carex otrubae, C. serotina, Lathyrus pannonicus subsp. collinus, Leucanthemum irrcutianum, Minuartia viscosa, Peucedanum rochelianum, Quercus pubescens, Trifolium diffusum, T. micranthum) and a notomorpha (Cirsium × tataricum) were also noticed.
