Cardamine occulta Hornem. in Hungary, and other stowaways of the ornamental plant trade
195–214Views:1337During 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.

Data on spreading cultivated species in Hungarian botanical gardens
62–78Views:878Our article provides data of 186 spreading cultivated taxa in Hungary. Among these, the spreading of 40 species in botanical gardens was not known until now. During our work, we examined the arboretums of Tiszakürt, Szarvas and Erdőtelek, the agrobotanical garden of Tápiószele (located in the National Centre for Biodiversity and Gene Conservation), the botanical garden of the Eszterházy Károly Catholic University in Eger and the De la Motte Castle Park in Noszvaj. We collected further data on the lately identified Cardamine occulta and the spreading Veronica peregrina taxa, which spread mainly through plants sold in pots. Besides the already known two Juglans species, we found four new potentially spreading ones from the family of Juglandaceae (Carya cordiformis, C. ovata, Juglans cinerea and J. microcarpa). We also found seedlings and saplings in the case of all the investigated Abies species. We found the seventh Hungarian occurrence of Ludwigia grandiflora in the artificial lake of the Arboretum of Szarvas. The quantity of new occurrences reported in this paper highlights the need for further research in living collections in Hungarian botanical gardens.

White willow riparian forests along the upper Tisza River, Hungary
78–100Views:383Forests of the Tisza floodplain in the northwestern part of Hungary include white willow riparian forests (Leucojo aestivi-Salicetum albae) that are phytosociologically little studied. This study summarizes the characteristics of this community based on 25 phytosociological relevés. These forests grow mostly on mud and raw alluvial soil in the low-lying parts of the lower terraces of the floodplain. They are easily separated by their species composition and underdeveloped shrub layer from white poplar gallery forests (Senecioni sarracenici-Populetum albae)., which grow on higher lying ground with rather light sandy soil and typically possess a pronounced shrub layer. The understory of their stands may often host plants that are rare or completely absent in other parts of the country, such as Cardamine amara, Cardamine flexuosa, Cardaminopsis arenosa, Carex pseudocyperus, Carex remota, Chrysosplenium alternifolium, Leucanthemella serotina, Leucojum aestivum, Oenanthe banatica, Scrophularia scopolii, Telekia speciosa, Vitis sylvestris. This community is classified in the „Salicenion albae-fragilis Kevey 2008” suballiance.

Data on alien vascular plant species in Hungary I. (1–6)
65–80Views:1186This is the first in a series of papers by various authors presenting previously unpublished data relevant to the knowledge of alien vascular plants in Hungary. This paper deals with the families Pteridaceae, Brassicaceae, Plantaginaceae, Rosaceae, Ranunculaceae, Fabaceae and Poaceae. It includes new area records and distributional considerations for Cochlearia danica and Plantago coronopus spreading along Hungarian road-network as well as records of Panicum riparium from the Northern Hungarian Mountain range based on field work and herbarium revision. We note the importance of checking the data previously collected as P. capillare. Floristic data of two species not previously recorded in Hungary (Cardamine corymbosa, Ranunculus marginatus) and 3 sporadically occurring alien species (Aphanes australis, Lepidium didymum, Medicago arabica), from garden centres in the Debrecen area were published. A 7-year long survival of a population of Adiantum capillus-veneris in a traditional, abandoned well is also documented between 2017 and 2024. The paper reports that traffic infrastructure can facilitate the spread of Elymus elongatus along roads.

Floristic data from the Great Plain of Hungary (Alföld)
304–316Views:674In this study we report relevant occurrence data of 49 species and hybrids and their habitats from the Great Plain registered in the period between 2011 and 2017. Due to importance for nature conservation, we present additional data of further 13 species. Most of the data are originated from riverine oak-elm-ash forests of South East Hungary (from the region of Gyula, Békéscsaba, Doboz settlements). The most important result of our study is the rediscovery of Gagea minima and Dictamnus albus. Besides, we report new occurrence data for the Great Plain (Alföld), as well as for the flora of the microregions in questions (e.g. Draba muralis, Nicandra physalodes, Cystopteris fragilis) and also present the data of the regionally endangered species (e.g. Inula helenium, Ophioglossum vulgatum). Some rare weed taxa (e.g. Calepina irregularis, Cardamine impatiens), spreading adventive taxa (e.g. Chorispora tenella, Euphorbia maculata, Phytolacca americana, Ph. esculenta, Sicyos angulata) and in surveys rather underrepresented species (e.g. Loranthus europaeus, Arabis hirsuta, Rumex confertus) are reported too.

Oak-ash-elm forests in the Nyírség
179-220Views:527This paper presents phytosociological analyses of oak-ash-elm forests of Nyírség, NE Hungary. These climatically azonal forests grow in habitats where the soil is under the continual influence of the groundwater table, which maintains rather mesic conditions. They are particularly rich in Fagetalia elements (Actaea spicata, Allium ursinum, Anemone ranunculoides, Asarum europaeum, Athyrium filix-femina, Cardamine bulbifera, Carex pilosa, Cerastium sylvaticum, Chaerophyllum aromaticum, Corydalis cava, Dryopteris filix-mas, Epipactis helleborine agg., Euphorbia amygdaloides, Galeobdolon luteum, Galium odoratum, Hedera helix, Isopyrum thalictroides, Lathraea squamaria, Lathyrus vernus, Lilium martagon, Majanthemum bifolium, Mercurialis perennis, Milium effusum, Polygonatum multiflorum, Pulmonaria officinalis, Ranunculus cassubicus, Salvia glutinosa, Sanicula europaea, Scilla vindobonensis, Stachys sylvatica, Stellaria holostea etc.) typical in the submontane regions of this part of Europe. It is possible that they are remnants of the vegetation dominating the region under the less continental and more moist climate during the Beech phase (2500–800 BC) of the Holocene.

Floristic records from Northern Hungary III. Zemplén Mts
109–172Views:783We report new floristic data collected from the Zemplén Mountains between 2004–2022. Altogether, 1215 occurrences of 133 species were recorded from 33 Central European Flora Mapping quadrats. We present occurrences of so far not reported or rare species, e.g., Carex appropinquata, C. cespitosa, C. disticha, Centaurea stenolepis, Scabiosa columbaria, Tephroseris aurantiaca. We put special emphasis on occurrence data of geobotanical importance, such as Anthriscus nitidus, Echium maculatum, Lunaria rediviva, Nepeta pannonica, Oreopteris limbosperma, Petasites albus, Primula elatior, Thlaspi jankae, Veronica montana, as well as newly rediscovered species based on archive data: Cirsium rivulare, Parnassia palustris. We mention common species, which are lacking data from the area, e.g., Adoxa moschatellina, Allium flavum, Cardamine amara, Dipsacus fullonum, Galanthus nivalis. Moreover, we report numerous new occurrences of taxa typical to the Zemplén Mts.: Aruncus dioicus, Huperzia selago, Lycopodium annotinum, Securigera elegans etc. We complete the enumeration with additional data from the literature and herbaria.

Floristic data from the northern edge of the floristic region ‘Crisicum’ (NE Hungary)
275-294Views:541This paper reports new floristic data of 161 taxa. Most of these data were collected between 2011–2013, and are coming from the northern edge of the floristic region 'Crisicum', the NE part of the Great Hungarian Plain, which is a little-known area from a floristic point of view. 43 CEU quarterquadrates and territory of 35 settlements are represented by the dataset. The paper reports occurrence localities for legally protected (e.g. Ophioglossum vulgatum, Stellaria palustris, Ranunculus polyphyllus, Thlaspi jankae, Lathyrus palustris, Elatine spp., Lycopsis arvensis, Lindernia procumbens, Cirsium brachycephalum, Cyperus pannonicus), strictly protected (Armoracia macrocarpa, Vicia biennis) and some little-known (e.g. Cardamine parviflora, Reseda luteola, Melilorus dentatus, Veronica catenata) taxa. Numerous data of alien species (e.g. Lepidium densiflorum, Euphorbia maculata, Sicyos angulatus, Erechtites hieracifolia, Elodea nuttallii, Elymus elongatus, Eleusine indica, Sorghum halepense, Eriochloa villosa) are also published. The most important data are documented by voucher specimens deposited in herbarium of Debrecen University (DE).

Data on the distribution of some protected plant species and on their presence in secondary habitats
183-199Views:2259In this paper, I publish my floristic data on some protected and strictly protected plant species collected in Hungary between 2016 and 2021. The data published in this paper cover 31 micro regions of Hungary, but most of them come from the Great Hungarian Plain, especially from Pest and Bács-Kiskun counties. I describe the occurrences of 41 protected and three strictly protected vascular plant species (two ferns and 42 flowering plants), some of which represent new data for the particular micro region or even larger geographical areas (e.g. Botrychium matricariifolium, Thlaspi alliaceum and Nasturtium officinale). For some species, the published data either come from floristically understudied areas (e.g. Ranunculus illyricus, Vinca herbacea and Cardamine amara) or are considered rare in the certain region and/or in the whole country (e.g. Apium repens, Cnidium dubium and Vicia narbonensis). For other species, the newly reported occurrences are presented as complement to the already known distribution data (e.g. Cephalanthera damasonium, C. rubra, Linaria biebersteinii, Sonchus palustris and Agrostemma githago). In support of the nature conservation actions, I provide data from the flora of some floristically understudied micro regions (e.g. Dorozsma-Majsai Sand Ridge, Bácskai Loess Plain) and try to highlight the role of canals in Hungary in species and biodiversity conservation, by the example of the Danube-Tisza canal. In this manuscript, I publish data on twelve protected plant species from the Danube-Tisza canal and its canal bank (eg. Peucedanum palustre, Carex paniculata, Clematis integrifolia).

Chorological notes on the vascular flora of Hungary
85-119Views:764The paper presents 1593 current chorological data of 584 taxa (species, subspecies, varietas, hybrids) from Hungary, collected during the last few years. All of these connected also to a total of 184 CEU quadrats. Among the species characteristic to the natural habitats, we highlighted the records of several species protected in Hungary (Adoxa moschatelina, Althaea cannabina, Cardamine parviflora, Centaurium pulchellum, Gagea pusilla, Orobanche reticulata, Potentilla patula, Rosa zagrabiensis, Spergula pentandra, Trifolium diffusum, Valerianella dentata, V. rimosa, Veronica officinalis, Viola collina and V. pumila). In the Northern part of Hungary, we observed the establishment of Cerastium dubium and Ranunculus pedatus at several places along roadsides, which species have been known from the surrounding saline areas for a long time, but their appearance at roadsides is relatively new phenomenon. In addition, Aegilops cylindrica, Crypsis schoenoides, and Fumaria vaillantii subsp. vaillantii were found in one location – each species on roadsides. Along the railway tracks, we found disturbance-tolerant pioneers of rocky grasslands, open sandy and loess grasslands, e.g. many population of the native Androsace elongata, Anthemis ruthenica, Centaurea arenaria, Draba nemorosa, Erodium ciconium, Medicago monspeliaca, Microrrhinum minus, Saxifraga tridactylites and Vulpia myuros were found, as well as numerous ruderalia and the archaeophyt such as Aegilops cylindrica. In addition to the more common species from the urban flora, we present some new data on the occurrence of the rarer Amaranthus blitum subsp. emarginatus, Chenopodium glaucum, Ch. murale, Ch. opulifolium, Ch. vulvaria and Euphorbia peplus. We have also listed some of the rarer field weeds and species that can establish in younger and older old-fields. Bromus secalinus has been found in several places in the northeastern part of Hungary. We also observed Calepina irregularis, Centaurea solstitialis, Centaurium pulchellum, Erysimum cheiranthoides, Filago lutescens, Fumaria officinalis subsp. officinalis, Geranium dissectum, Misopates orontium, Myagrum perfoliatum, Reseda phyteuma, Spergularia salina and Veronica anagalloides populations. Erodium hoefftianum is a member of the natural flora, but is now found only in old-fields. We found some pasture weeds in regions where they are not common (e.g. Bupleurum tenuissimum, Cerastium dubium and Trifolium striatum). The study also presents some species that are data deficient for taxonomic reasons, but not very rare ones (or we don’t know that). This group includes Arabis sagittata, Bolboschoenus glaucus, Bromus commutatus, B. racemosus, B. ramosus, Fumaria vaillantii subsp. schrammii, Ononis spinosiformis subsp. semihircina, Potentilla collina and Viola suavis “white morfotype”. We have drawn attention to the effect of ecological-botanical works on flora-influencing. We found Anthemis ruthenica (species of sandy grasslands) in a mountain meadow, which is probably the result of seeds accidentally introduced by researchers. Finally, the paper provides data on the current distribution of hybrid taxa. A new individual of Betula ×rhombifolia was established in the Mátra Mts. We found some Euphorbia individuals that appeared to be a transitional form between E. esila and E. virgata (E. ×intercedens; Eu. esula subsp. saratoi). We also present some Verbascum and Viola hybrids. Hybrids were determined on a macromorphological basis.
