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.

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.

Habitats and protected plants of Cuha-valley (Bakony Mts, W-Hungary)
80-88Views:66Floristic data were collected and habitat mapping was performed between 2009 and 2011 in the valley of Cuha-creek. During the field work occurrences of 423 vascular plant species (including 31 protected taxa) were recorded. Potentilla indica represents a previously unknown alien taxa of the study area. The dominant vegetation type of the Cuha-valley is beech forest. Further characteristic, important habitats are scree, ravine and hilltop forests. On the southern part of the valley – in close proximity of the Cuha-creek – expansion of several alien plants (Impatiens glandulifera, Fallopia spp., Heracleum mantegazzianum) were observed.

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 Atlas Florae Hungariae VIII.
238-261Views:223The current paper is the 8th in the series aiming to contribute with new distribution data to the maps published quite recently in Atlas Florae Hungariae. Distribution data of 539 plant taxa from 157 flora mapping units is presented in this study, most of them are located in the western half of the country. As a result of systematic surveys, more than 190 new species were found in a single flora mapping quadrat. In another survey along some asphalted roadsides Puccinellia distans was found as a new species for 68 flora mapping grid units. All these indicate the necessity of further systematic research and publication of floristic results in papers like the “Contributions…” series. Most of the enumerated taxa are frequent, treated usually as weeds, but some of them are sparse and scattered or rare in Hungary (e.g. Nigella arvensis, Vaccaria hispanica, Rumex pulcher, Urtica urens), and in some cases they are legally protected plants in Hungary (e.g. Asplenium adiantum-nigrum, Dryopteris affinis, Gymnocarpium dryopteris and Huperzia selago). We also listed some casual alien plants and naturalized species that were not mentioned in the last neophyte list of Hungary (e.g. Acer cissifolium, Cyperus alternifolius, Gaillardia aristata, Galanthus elwesii). In the Outlook we pointed out the insufficient survey of some synanthropic (urban) habitat types in Hungary, like verges, gardens and flowerbeds that can be the hotbed of established species or can serve as stepping stones for potential invaders.

Natural values of Mt Somsich near Villány, threatening factors and necessary conservation actions
55–62Views:80Although Mt Somsich is very rich in natural values, it is still a poorly-known part of the Villány Mts. Apart from a few scattered floristic data and a short habitat description, its vegetation is virtually unexplored. The aim of this paper is to characterize the natural and semi-natural habitats of Mt Somsich, give the current population sizes of the protected plant species, survey their threats, and offer suggestions for further conservation activities. Disregarding the totally artificial habitats, five habitat types were distinguished on Mt Somsich, of which the pubescent oak scrub is the most valuable. A total of 15 protected plant species have been reported so far, of which 11 are currently recorded on Mt Somsich. The local wildlife is affected by loss and fragmentation of habitats as well as illegal activities. The negative influences cannot be fully eliminated, but could be minimized.

New occurrence of Myricaria germanica in a secondary habitat (NE Hungary)
118–122Views:22542In this paper, we report a new occurrence of Myricaria germanica (L.) Desf in a secondary habitat from the north-eastern part of Hungary, from the edge of the Bükk Mountains, in a slag dump in Miskolc. The plant is established on a steep wall formed during the extraction of slag. Due to the erosion of the wall, occasionally a few plants fall off. The age of the dead specimens is between 5 and 13 years, based on their growth rings. The population of about 50 individuals is the largest (but perhaps the only) living population of the species in Hungary. Other rare and protected species (Epilobium dodonaei Vill., Dysphania botrys (L.) Mosyakin & Clemants, Dryopteris carthusiana (Vill.) H.P. Fuchs, Polystichum aculeatum (L.) Roth ex Mert.) have also been found in the slag heap area.

Cardamine occulta Hornem. in Hungary, and other stowaways of the ornamental plant trade
195–214Views:441During the study of the weed flora of garden centers in Hungary (among 2017–2020), remarkable populations of Cardamine occulta Hornem., a new alien for the Hungarian flora were found. C. occulta was present altogether in 51 of the 53 visited sites. Dominantly the regularly irrigated and continuously moist microhabitats (pots, containers, muddy surfaces of geotextile-covered beds etc.) were colonized. During the revision of our recently collected specimens, deposited in JPU and DE herbaria as Cardamine hirsuta L., further individuals proved to identical with this till overlooked species. One of them (27.08.2004., Heves county: Eger [8088.3; 8188.1], coll. by A. Schmotzer, deposited in DE collection) proved to the third documented occurrence in Europe, comparing to the accessed literature data. Eclipta prostrata (L.) L. and Urtica membranacea Poir. are also new aliens for the Hungarian flora. Several introduced individuals of these taxa were found in containers of imported thermophilous woody ornamentals at 4 and 2 sites, respectively. Tens of individuals of Eclipta prostrata were also found in a sapling-bed at another site. New populations of scarce or rare Euphorbia prostrata Aiton, E. serpens Kunth and Veronica peregrina L. were also documented.

Cyperus odoratus in Hungary
157–164Views:278Eleven species of the genus Cyperus have been reported from Hungary so far, of which 3 are certainly aliens. A small population of C. odoratus, new for the flora of Hungary, was found along the River Danube near Foktő settlement (Bács-Kiskun County, S Hungary) in late autumn of 2019. On this occasion blooming specimens were observed in the floodplain ruderal vegetation on the bank of a fork of the Danube. This species is widespread in the tropical and subtropical regions of the World, and was first introduced to Europe in the early 1950s. More recently it has been spreading along certain rivers of Italy and Spain. It was discovered along the river Danube in Romania in the early 1990s, and later at the upper parts of the river in Bulgaria, Croatia and Serbia. Its introduction into Hungary is connected with the Danube, too. Based on foreign experience, it is probable that C. odoratus will be spreading along the Hungarian Danube system, hopefully, not as an invasive species.

Bryofloristical study in the Brunszvik manor park in Martonvásár, Hungary
198–206Views:153This is the first bryofloristic study in the Martonvásár manor park. In our survey in 2015, 56 species (6 liverworts and 50 mosses) were found in the park. Most of them are considered to be common in Hungary, but an endangered (Eurhynchium speciosum), a vulnerable (Orthotrichum patens) and five near-threatened species (Aphanorrhegma patens, Orthotrichum obtusifolium, Orthotrichum pumilum, Pseudocrossidium revolutum, Riccia cavernosa) were also found. These results point out the nature conservation value of the manor park.

Contributions to the algal flora of a recently-formed peat moss bog near Kőszeg (W Hungary)
113–130Views:367The 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.

Seed dispersal and habitat preference of the endangered Lesser White-fronted Goose (Anser erythropus L.) and larger goose species in the Hortobágy National Park
136-147Views:149Several studies found that waterfowl are important endozoochorous dispersal vectors for plant species. Germination of the seed content of their droppings provides valuable information on their diet and also on their role in seed dispersal. Our aim was to analyse the seed dispersal potential of the critically endangered habitat-specialist Lesser White-fronted Goose (Anser erythropus) in their autumn and spring staging areas in Hortobágy National Park. The study was supported by the LIFE10-NAT/GR/000638 project. We also studied the seed dispersal potential of larger generalist goose species foraging in the same areas, such as Greater White-Fronted Goose (Anser albifrons Scopoli) and Greylag Goose (Anser anser L.). We asked the following questions: (i) Which habitat types are the most frequently used by Lesser White-fronted Goose and larger goose species? (ii) Is the different habitat preference of Lesser White-fronted Goose and larger goose species reflected in the seed content of their droppings? (iii) Are there seasonal differences between the seed content of spring and autumn droppings? We identified the most frequently used feeding habitats. We collected 40 droppings of Lesser White-fronted Goose and larger goose species per site in April and October 2012, in total we collected 720 droppings per species. Droppings were concentrated and spread on trays filled with sterilised potting soil. Samples were germinated in a greenhouse from April to November 2013. In total we germinated 21 plant species from the goose droppings, which suggests that goose species play an important role in seed dispersal. We found that Lesser White-fronted Goose dispersed more species typical to alkali habitats, and fewer weeds compared to larger goose species. Lesser White-fronted Goose and larger goose species used a wide range of feeding habitats, thus, they play an important role in dispersing seeds between habitats along a moisture gradient. Total species number and species number of plant functional groups were higher in autumn droppings. Seed content of the droppings suggests that Lesser White-fronted Goose is confined to natural habitats, thus for the effective protection of this critically endangered species it is crucial to preserve its natural feeding habitats.

Contributions to the knowledge of biology and Hungarian distribution range of Orobanche reticulata
95-98Views:398Some 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.

The occurrence of Pterygoneurum squamosum Segarra et Kürschner on a reclaimed waste storage near town Győr (NW Hungary)
23-27Views:107In the article a new locality, range map and habitat description of Pterygoneurum squamosum is provided from Hungary. Differently from up to the present known localities, the moss was found on anthropogenic habitat, eroded and clayey soil surface. Considering the climatic and soil conditions there, probably this rare Mediterranean species has wider ecological tolerance, so we come across it on further man-made habitats, as well as on loess walls.
