The purple viper's bugloss (Echium plantagineum), a new adventive species for Hungary
199-206Views:1249Following global trends, the number of newly established alien plant species is increasing in Hungary. Not only professional scientists but also citizens could contribute to the discovery and documentation of new occurrences. One of the first records of the purple viper’s bugloss (Echium plantagineum L.) in Hungary originate from an online group dealing with wild plant species identification. This species is native in Western Mediterranean countries, and is introduced to other continents. In Australia, it is a well-spread, largely problematic invasive species, and it might show similar tendencies in Hungary as well. In order to acquaint the wider public with this species, we present its morphology, phenology and other characteristics and provide a possible inlay in the Hungarian identification key.

The historical occurrence of Digitaria ciliaris in Hungary – results of a herbarium survey
53–62Views:416Revision of genus Digitaria in BP Herbarium Carpato-Pannonicum collection helped to discover the historical occurrence of Digitaria ciliaris (Retz.) Koeler from Győr, in the area of an old cotton and wool processing and textile factory. However, it has been proved that the previously published Hungarian records of the species are all wrong, as the Digitaria-keys of Hungarian herbals misinterpreted the taxon, mainly as a synonym of D. sanguinalis subsp. pectiniformis. The herbarium survey confirmed that D. sanguinalis is the most common taxon in Hungary. D. sanguinalis subsp. pectiniformis is also widespread, but probably somewhat under-mapped. Probably not native to Hungary, most probably an archeophyte taxon. Specimens have been collected from disturbed habitats associated to railways and from xerothermic vineyard areas for over a hundred years. D. ischaemum is certainly native to the region, with a recognisable natural distribution pattern, and is found mainly in the sandy and gravelly soils of the lowland and hilly areas of the country. This species has recently become more common in urban areas across the country with the recent spread of sand-lined pavements. D. ciliaris of tropical/subtropical origin is a casual alien species that was formerly present in the Hungarian flora.

Occurrences of sea lyme grass (Leymus arenarius) in the Kiskunság, Hungary
106-108Views:385We present six new occurrences of a rare non-native species, the sea lyme grass (Leymus arenarius (L.) Hochst.) in the Kiskunság region, Hungary. The populations grow in disturbed, secondary habitats (e.g., abandoned fields, recultivated landfills, surroundings of farms), but one of them begins to expand on the adjacent natural open sandy grassland. Most of the occurrences occupy several hundred square meters and in some cases it forms almost monodominant stands. We suppose that the species has the potential to become an invasive species in this inland sand region.

Data on the flora of the burial mounds of the Great Hungarian Plain
31–44Views:206In this paper, we present plant occurrence data from ancient burial mounds, located in the Danube–Tisza Interfluve (Praematricum and Colocense) and in the Trans-Tisza region (Crisicum), Hungary. We report data on 45 vascular plant species and one fungus (Morchella steppicola) from a total of 109 mounds. Of the species presented, 13 taxa are protected in Hungary, some of which are not rare in the study region (e.g. Aster sedifolius, Astragalus asper, Linaria biebersteinii, and Ornithogalum brevistylum). We present new occurrence records of some spreading annual species (e.g. Aegilops cylindrica, Crepis pulchra, and Trifolium diffusum), as well as data on some species that have not been previously reported from mounds (e.g. Agrostemma githago, Chaerophyllum bulbosum, and Dryopteris filix-mas), and we also publish the occurrences of an alien species (Lolium multiflorum) on burial mounds. In terms of plant biogeography, the occurrence of Orobanche reticulata in Kengyel and Oxytropis pilosa in Tömörkény is considered an especially important data.

Data on alien vascular plant species in Hungary I. (1–6)
65–80Views:917This 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.

Three new grass species to the alien flora of Hungary: Paspalum dilatatum, Phalaris aquatica and Panicum schinzii
63–76Views:574In this paper, we present the new occurrence of two grass species previously unknown in the flora of Hungary and one grass species for which we have only one historical record. Panicum schinzii Hack. is an annual species from South Africa, Paspalum dilatatum Poir. is a perennial species originating from South America, and Phalaris aquatica L. is also a perennial taxon native to the Mediterranean. The only well-developed individual of Panicum schinzii was found on a gravel reef of the Rába river in Western Hungary, while the two newly observed perennial grass species appeared in the Great Hungarian Plain: a single individual of Paspalum dilatatum was observed in a suburban environment on the southern edge of the town of Soltvadkert, while a small population of Phalaris aquatica occurs along a highway near Szeged. In this paper, we describe the European distribution and habitat preference of these three species, we assess their invasion potential and we fit them into the Hungarian dichotomous key of vascular plants. Although we cannot state with certainty that the specimens of Panicum schinzii, Paspalum dilatatum and Phalaris aquatica we report here are the first ones that have ever appeared in Hungary, but their localities and the numbers of individuals suggest that they have entered the country very recently. The annual Panicum schinzii certainly arrived to Hungary naturally by the river Rába, while the perennial Paspalum dilatatum and Phalaris aquatica are more likely to have been introduced by human activities, but both inadvertently. Paspalum dilatatum arrived to its site near Soltvadkert by accident, in the form of propagules in some intentionally sown seed mixture. The fact that all three species are considered in some countries to be invasive or at least problematic species is a cause for concern.

Occurrence of ferns in secondary habitats of the Great Hungarian Plain
3–14Views:690In this study we report the occurrence data of 14 fern species from the area of the Danube–Tisza Interfluve and the Tiszántúl (Great Hungarian Plain). All data have been collected from secondary habitats, such as buildings and man-made structures, pine plantations and canals. We present new data on seven protected and one alien fern species (Azolla filiculoides). Seven and six species were found together on the brick walls of old buildings near the railway stations in Bácsalmás and Baja, respectively. The new occurrences of Gymnocarpium robertianum, Pteridium aquilinum, Asplenium adiantum-nigrum and Polypodium vulgare have great importance from a floristic point of view. The latter two species were recorded both in pine plantations and on brick walls.

Floristic records from northern Pest and western Nógrád counties
193–202Views:281This paper presents significant floristic records from recent years in the northern part of Pest County and the western part of Nógrád County. The 100 occurrences represent 54 species, of which three are pteridophytes and 51 are flowering plants. The occurrences are new at least at the microregional level or, in some cases, confirm old or uncertain records. Fifteen species are newly recorded or have significant new data for the North Hungarian Mountains. Most of the species are aliens or native plants showing secondary spread along roads. For several of them, a northward expansion of their distribution in Hungary has been identified.

A new alien species in Hungary: the occurrence of Sabulina tenuifolia in Budapest
15–26Views:484Railways are important introduction and dispersal corridors for plant species. The first establishment and spread of many alien plant species in Hungary can be linked to railways nowadays. Sabulina tenuifolia (L.) Rchb. is a sub-Atlantic–sub-Mediterranean–Western-Asian plant, which was not previously known from the flora of Hungary, but a small population of the species was found in Budapest, at the Rákospalota-Újpest railway station. The plant was probably introduced as a stowaway of rail transport and its further spread along railways is expected. The inclusion of the species in the Hungarian plant identification key has been published in the article.

Taxonomic revision of alien Ludwigia species in Hungary
153–164Views:616Some tropical Ludwigia species have been planted as ornamentals in Hungarian thermal springs since the 1920s. Although they have become naturalised or even invasive in a few places, their specific identity remained generally uncertain. Our herbarium and field studies revealed that three species of alien water-primroses occur in Hungary. The most frequently planted one is Ludwigia repens, which is, however, a sporadic species in its native distribution area. We have found this species in several parts of the country. Although a few escaped and self-sustaining populations were also observed, this species has appeared to be non-invasive so far. Ludwigia grandiflora appeared in Hungary at the beginning of the 2000s. At the moment it is known from three localities, though spreading rapidly, becoming already invasive in its locality at Tata city. A similar species, L. peploides has recently been reported from two localities, where it forms small stands; the success of its naturalisation can be assessed in the future. We found no evidence for the Hungarian occurrence of L. alterniflora that had been published from Eger city. Therefore we suggest deleting this species from the current Hungarian checklist.

The clammy goosefoot (Chenopodium pumilio R.BR.) in Zugló (Budapest) and new data on the distribution of invasive species in NE Hungary
221-226Views:392The paper summarise occurrences of some rare invasive weeds of Hungary. We found currently second population at the Australian origin Chenopodium pumilio in Budapest (Zugló) in September 2016. Further, 27 occurrence data of 8 other species (Amaranthus deflexus, Echium maculatum, Lepidium densiflorum, Oxybaphus nyctagineus, Panicum dichotomiflorum, Portulaca grandiflora, Sarothamnus scoparius, Tragus racemosus) is also reported in the persent paper from the ‘Északi-középhegyég’ area (Northeast-Hungary), and some data from beside the Hungarian–Slovakian border, especially settlements, strongly disturbed places (especially road curbs, pavement cracks, train stations), indicating the Central European flora mapping system quadrate number. Voucher specimens were deposited in herbarium of Hungarian Natural History Museum, Budapest (BP).

Data to the flora of Southern-Nyírség and its surroundings
68–85Views:2013In this paper we provide data on the flora of Monostorpályi, a floristically underrepresented settlement in South-Nyírség and Berettyó–Kálló interfluve, and publish some interesting floristic observations from the Debrecen city area. In our compilation we provide data on 58 plant species. Among the species listed in the enumeration we find taxa from the region not previously reported at all (Lathyrus nissolia, Gagea villosa, Catabrosa aquatica, Potamogeton lucens, P. pusillus). In total, we publish new occurrence data for 16 protected plant species, which are generally typical of the natural habitats of the Nyírség, but are on the decline overall (e.g. Hottonia palustris, Dianthus superbus, Cirsium rivulare, Lychnis coronaria). We also provide data on the distribution of some rare or declining weed species (Anthemis cotula, Myagrum perfoliatum, Agrostemma githago) and confirm the previously known occurrence of some poorly known plant species (Luzula pallidula, Carex hordeistichos). Furthermore, the spread of some alien species (Broussonetia papyrifera, Phyllostachys sp.) is also highlighted.

Multiclavula mucida (Basidiomycota) and other cryptogamic taxa in the Hungarian flora
173–184Views:783The 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.

Contributions to the escaped, naturalised and potentially invasive species of the Hungarian adventive flora
111-156Views:1015In 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.
