Vaccinium microcarpum (Turcz. ex Rupr.) Schmalh. in Hungary
71–76Views:100The 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 V. microcarpum, whereas the Bereg-plain plants represent V. oxycoccos.

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 Calamagrostis stricta (Timm) Koeler in the Southern Nyírség (E Hungary)
188-196Views:145This 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.

Aphanes arvensis L. in the Crisicum (E Hungary) and further data on the flora of Hungary
253-256Views:94New 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.

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 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.

Data to the flora and geobotany of Kisalföld (Lesser Plain) region, NW Hungary
235-253Views:128Lesser 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 ramosus, Hypericum dubium, Lathyrus 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 rivulare, Dryopteris dilatata, Equisetum telmateia), loess-connected species mainly on the Moson Plateau (Agropyron cristatum, Allium atroviolaceum, Euphorbia salicifolia, Viola ambigua); and occurrences of species on sandy soils near the Lake Fertő (Draba nemorosa, Stipa pennata).
- We explained the known localities of several salt tolerant species (e.g. Carex divisa, Crypsis alopecuroides, Juncus maritimus, Limonium gmelinii, Suaeda 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 tataricum, Betula pubescens, Fraxinus ornus, Quercus petraea, Salix pentandra).
- We discussed the regional nature conservational status of several protected and/or threatened species (e.g. Allium carinatum, Allium suaveolens, Carex strigosa, Hottonia 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
111-156Views:545In 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.
