  Orchis mascula subsp. signifera is a rare, legally protected and endangered species of the Hungarian flora. Currently it is recorded from 25 flora mapping grid cell in Hungary. The westernmost Hungarian occurrence of the species was documented by a voucher collected by Dénes Gotthárd in 1976. After four decades the occurrence of O. mascula in the Keszthely Mts was confirmed in 2015. The local habitat preference and major threats to the taxon are briefly discussed.

  Records of 26 vascular plant species from the territory of Sopron Mountains (16 species) and Sopron Basin (11 species) are presented. Our field works (between 2014 and 2020) focused on some localities at the eastern and southern parts of the region. Tetragonolobus maritimus is new for the Sopron Mts, whereas Ajuga chamaepithys and Lycopsis arvensis are new for the Hungarian part of the hills. Some protected plants like Agrostemma githago, Gentianopsis ciliata and Sesleria uliginosa were rediscovered in the region. Comments about all species and their local chorology are added. A remarkable degradation process of bogs around Harka village, caused mainly by insufficient water supply of meadows, was observed. The spread of occurrences of several naturalized weed such as Aegilops cylindrica, Galium parisiense, Geranium rotundifolium, Kochia scoparia, Lepidium virginicum, Oenothera salicifolia, Sagina apetala subsp. apetala and Verbascum lychnitis was noticed. The most surprising observations refer to Galium parisiense; the spread of the species by transport had no precedent in Hungary before.

  A new occurrence was found of the rare non-native species, Cycloloma atriplicifolia (Spreng.) J. M. Coult. in the Northern part of Kiskunság, Hungary on 02.07.2019 on a sandy road [N 47.297476°, E 19.382936°, KEF: 8782.1]. This is 80 km apart from the first and until now single occurrence of this species in Hungary. The authors removed the individuals, however, some seeds could remain in the soil. It is assumable, that the species was spread by wheels of the car used by the authors, as they visited the original occurrence of the species and the new one during the autumn in 2018 with the same car. This new occurrence draws attention to an important, but overlooked invasion pathway: to the invasion with cars of ecologists.

  On 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).

  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 a review of the nomenclature, etymology, taxonomy, morphology, histology, life cycle, phenology, reproduction, habitat preference, biotic interactions, biologically active compounds, micropropagation, application possibilities and conservation status of Siberian flag (Iris sibirica L.) can be found. Leaf traits, phenological data, seed-set, thousand-seed weight, germination, growth rate and soil characteristic data are published based on original observations:

  • Leaf area is between 25,3 and 52,9 cm², its dry mass is 232 and 272 mg/g, specific leaf area is 14,5 and 15,0 m²/kg; based on measurement of 5–5 leaves of sibirica, collected from Tapolca and Létavértes (Hungary) in May of 2014.
  • Based on herbarium dataset, blooming of sibirica begins at the end of April and lasts to early-July, contrary to the literature data (May–June).
  • Capsules contain (0–)58–76(–121) fertile seeds. (20–)60–80(–90)% of ovules develops to (seemingly) viable seeds, meanwhile the other ovules remain as aborted ones or develop to infertile seeds (probably because of absence of resources); based on fruits collected from Regéc (Hungary) in 2014 and 2015.
  • Thousand-seed weight of sibirica is 8,8298–11,2914 g (based on 3×100–100 seeds collected from Regéc and Tapolca in 2014 and 2015), which is lower value than the literature data.
  • In our germination test (50–50 seeds sowed to wet soil, after different treatments) 14% of scarified seeds, 6% of scalded seeds, 4–4% of imbibed and control seeds, 0–0% of cooled and refrigerated seeds are germinated. Scarified seeds germinated in the 8–26^th days, imbibed seeds 15–19^th days, control seeds 16–20^th days, scalded seeds 20–23^th days after sowing. It seems that scarification stimulates, meanwhile temperature-treatments inhibit the germination. Until 18 weeks the seedlings grow to 30 cm (in mean) and develop 5–7 leaves (in mean). After the 14^th week, the first and littlemost lateral leaves are necrosed.
  • Analyses of soil samples collected from 17 locations of sibirica in Hungary, suggest that the species prefers highly acidic to slightly alcalic, lime-free to highly calcareous soils with generally high amount of humus and clay, different amount of phosphorus, potassium and nitrogen and low concentration of salt.

  12 individuals of Botrychium matricariifolium (Retz.) A. Braun was found in the Matra Mts on 12. 06. 2020, on the edges of a mountain meadow. There are no historical or current records for this species from this area. The species formerly was listed as extinct species in Hungary. Recently, there are only two observations in the country; a single individual was found in the Mecsek Mts in 2008 (disappeared in the next year), and a seemingly stable population was found in the Kőszeg Mts in 2016.

  In 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.

  A 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).

  The paper deals with the species found during cryptogamic flora mapping in 2023 that are remarkable from a floristic, taxonomic or conservational point of view. We present data from the Bükk Mts of two Trapeliopsis species which appear to be rare in Hungary. Multiclavula mucida, which is ap­parently a rare basidiomycete lichen species in Europe that prefers humid, montane habitats was dis­covered in the Mecsek Mts as a new species for the Hungarian flora. Of the knothole moss, Anacampto­don splachnoides, which is now thought to be entomophilic, we communicate the only extant popula­tion from Southern Transdanubia. We report the first occurrence of the atlantic-mediterranean Lepto­don smithii from the Hungarian side of the Great Hungarian Plain. Numerous data of the corticole Neck­era pennata indicate that in Hungary the distributional centre of this species is situated in the county of Baranya in the lowlands. New data from the Bükk Mts underline that in the Pannonian region Buxbaumia viridis is primarily a terricole species of acidophilous beech forests. We communicate the first occurrence from the lowlands of the alien lignicolous Sematophyllum adnatum which is danger­ous­ly spreading in Europe, at the same time one of the most vigorous populations in the Pannonian region. The third Hungarian occurrence of Callicladium haldanianum, a species that seems to spread in bogs, as well as the second occurrence of Racomitrium lanuginosum, growing abundantly on an ande­site boulder scree in Mátra Mts, are also reported here. Of Phegopteris connectilis we present in photo­graphic docu­mentation the first extant population from Southern Transdanubia, and we discuss whether the first publication from Mecsek Mts is correct or exact. In addition to listing the floristic data, we also briefly discuss the (mis)use of distribution data in the context of climate change, the difficulties of distinguish­ing the microtaxa of some pteridophytes, e.g. Asplenium adiantum-nigrum agg. and Dryop­teris affinis agg., and we correct one of our previously published, erroneous Hedwigia stellata data. Some interest­ing data of other taxa (such as Leucobryum glaucum, Palustriella commutata, Tetraphis pellucida, Gym­nocarpium robertianum, Ophioglossum vulgatum) are also mentioned in the paper.

  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 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).

  The hybrid of leopard’s bane (Doronicum orientale Hoffm.) and the Hungarian leopard’s bane (Doronicum hugaricum (Sadler) Rchb.f.) was discovered by Tamás Nendtvich in the Mecsek Mts over Pécs in the 1820’s. During the past two centuries several researchers confirmed the occurrence of this plant in the region. The occurrences of the hybrid ever known are concentrated in a relatively limited range, and the single currently known occurrence is on “Zsuppon-parlag”.  In this paper, I report a new occurrence, found on 16th April 2020, close to the village of Kővágószőlős, which is 8 km away from the single currently known locality. I found only one flowering specimen, as well as five vegetative individ­uals with leaf rosettes. The parental species grew only 50 cm away from each other. Here, I provide a detailed morphological description about the flowering individual, and a vegetation relevé of the ac­companying species in a 10×10 m quadrat around the hybrid plant.

  Kurgans are ancient burial mounds built by nomadic steppic cultures across Eurasia.
  These monuments are important cultural landmarks, and often also preserve the remnants of dry grasslands even in intensively used agricultural landscapes. In the past centuries, many kurgans have been ploughed and their vegetation has been destroyed. Due to their recent inclusion in the agrienvironmental schemes in Hungary, crop production has been ceased on many kurgans in the past years. Here we present an interesting botanical discovery which we made during our country-scale survey of spontaneously recovering grasslands on kurgans. We discovered a large population of approximately 15,000 shoots of the protected loess grassland plant Prunus tenella Batsch (syn.: Amygdalus nana L.) on the Fekete-halom kurgan near Tiszainoka, in the centre of the Great Hungarian Plain. The mound had been used as an intensive cropland until 2014. Most probably, the plants could re-establish from some hidden shoots that could persist in the refuge provided by the concrete elements of a geodesic mark, and after the cessation of ploughing it could expand onto the north and west-facing slopes of the mound by sprouting and by germination from the persistent soil seed bank. Besides the conservation importance of this floristic discovery, it also suggests that spontaneous regeneration can be an effective restoration measure and that kurgans abandoned from agricultural cultivation can serve as suitable habitats for rare and endangered 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.

  The current paper is the 8^th 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.

While he was nation-wide recognized ornithologist, he extended our knowledge with many floristic data too, but we remember him mostly for his imaginative activity in nature conservation. He sent on his experience dozens of young conservationists and stood them on their own ways. His dedication carried with him all those who had predisposition. The Research and Ringing Camp of Fenékpuszta established by him has become one of the most important camps of the country for avian migration research and nature conservation practices.

  Himantoglossum adriaticum H. Baumann is a Natura 2000, CITES species and strictly protected plant in Hungary. During my field work (1992–2016) I realized some similarities in the characteristics of the habitats where the plant grows, so I wanted to know the land use history of the areas in question. The H. adriaticum population of Keszthely Hills was studied the longest time. There were annually 7–78 inflorescences between 1992–2016. Recently two further localities were found in Keszthely Hills. They grow in the edges of grasses used earlier as pasture, minor roadside verges and nearby abandoned vineyards. The largest population can be found in Sümeg region, majority of the individuals are along a paved road. Among the estimated 1000–2000 individuals 10 (2012) to 214 (2014) flowered. In Kőszeg, the lizard orchid grows in abandoned vineyards and in old traditional orchards. The maximum number of inflorescences was 165 (2016). In Bakony Hills its habitats are vineyards and orchards abandoned approximately 50 years ago. The size of H. adriaticum population here is nearly the same as in the Keszthely Hills. Four out of the five populations are growing on sites used as vineyard or orchard already in the years of the First Military Survey. The only exception is the population of Sümeg region. Every habitat is threatened by spontaneous forestation, but the species is able to find new habitats, so we do not worry about the drastic decline of the individuals in Hungary.

  Caldesia parnassifolia is a critically endangered and strictly protected species in Hungary. It was known only from one locality of occurrence so far, where it was last reported in 2003. Its new occurrence was discovered in Somogy county, in 2010. It appeared in an artificial pond created in the place of an originally swampy depression. Based on this newly discovered occurrence we can assume that other potential populations might still exist in South-Transdanubium, which could be rediscovered if similar conservation measures occur.

  Several 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.

  In Hungary Leucojum vernum is considered a plant species of montane character, distribu­ted predominantly in Transdanubia. Apart from some isolated localities (Zalaszántó Basin Mts, Tapolca Basin), the occurrences of the species are mainly confined to the region “Magas Bakony” and its pe­riphery within the Hungarian Middle Mts. In the spring of 2020 a large population was discovered by the author in the region “Súri-Bakonyalja”, which significantly expands the known local distribution range of the species. The new population, together with other phytogeographically significant species (e.g. Anemone nemorosa, Corydalis intermedia, Veratrum album), was found in a poorly explored val­ley system (Kisbér village: Báró-erdő). Based on all literature and herbarium records, the local distribu­tion range of L. vernum is surveyed.
