  • Contributions to the flora of railway-side pioneer habitats on Tiszántúl region
    86–101

    Verges have considerable importance to preserve diversity in arable landscape. The modernized railway embankments are a great surface to the spread of native pioneer or adventive (invasive) plant species. The new data are about the flora of railway embankments mainly from Tiszántúl region. I present some species found on railway verges (e.g. Equisetum ×moorei, Equisetum ramosissimum, Lycopsis arvensis, Euphorbia maculata, Lepidium densiflorum Tragus racemosus, Vulpia myuros). An especially important new data is the refinding of Galium humifusum in Hungary. Locally non-native and adventive species can use the blanketing materials (sand or gravel) of railway embankments as dispersal corridor and colonize them. The railwayside habitats could contribute to the conservation of rare native pioneer species.

  • Notes to the vascular flora of Sopron Mountains and its foreground

    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.

    During the last four years (2014–2017) that have passed since my last publication, I have been collecting 25 000 new floristic data for the territory of the Danube–Drava National Park. The most valuable and interesting records of 116 taxa are presented here, e.g. those of the strictly protected Digitalis ferruginea and Paeonia banatica, and the protected species Polystichum lonchitis, Dryopteris affinis, Doronicum orientale, Helleborus dumetorum, Corydalis intermedia, Spiraea media, Veratrum nigrum. New records of not protected but rare species, such as Lycopsis arvensis, Silene dichotomaTeucrium botrys, Thladiantha dubia, Vicia lutea, Hypochoeris radicata are also enumerated. Some curiosities are mentioned as well, including the sizes of the biggest (and probably the oldest) Crataegus monogyna, Hedera helix, Ruscus hypoglossum and Ruscus aculeatus individuals that were found during my field work.

  • Hybrid leopard’s bane (Doronicum ×sopianae) in the West-Mecsek Mts (SW Hungary)

    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.

    The authors present the most important floristic data of Tolna and Baranya coun­ties, col­lected together or separately in the last 15 years, or observed by other data providers. In total, occur­rence data of 140 taxa are reported. Most of them are protected species in Hungary, but the list also includes rarer weeds (Ado­nis flammea, Althaea cannabina, Aphanes arvensis, Bunias orientalis, Legousia speculum-veneris, Vicia lutea) and adventive species (Helminthia echioides, Oxybaphus nyctagineus, Rubia tinctorum). Several species of phytogeographical importance were also found in the forest-steppe vegetation of the loess areas studied. Occurrence of Linaria biebersteinii should be highlighted. L. biebersteinii is a very rare species in the Transda­nubian region, and is no longer found in Europe west of this region. The occurrence of Himantoglossum adriaticum is a new contribution to the flora of the southern Transdanubian region.

  • Data on the occurrence of sedge species (Carex, Cyperaceae) in and around South Nyírség (East Hungary)

    We provide floristic data on a total of 38 sedge species in the area of South Nyírség and its immediate surroundings. We also detected some populations of previously undescribed or rare species in the Hungarian Great Plain, such as Carex buxbaumii, Carex hartmanii, Carex umbrosa, and Carex paniculata. We report several new occurrences of species with little literature data from the area, such as Carex brizoides, Carex michelii, Carex pallescens, Carex elongata. However, during the last 13 years, we were not able to detect seven species previously mentioned in the literature. Herbarium data confirmed that some of the older Carex nigra occurrences for the area actually refer to Carex cespitosa. Based on herbarium data and the literature, we think that local data on Carex pairaei may largely refer to Carex divulsa subsp. leersii and/or Carex spicata. Contrary to many pieces of literature, Carex vulpina was not observed inside the sandy area.

    This 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 spicataAllium 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.

  • A new alien species to the Hungarian flora: Polypogon viridis (Gouan) Breistr.

    Polypogon viridis (Gouan) Bresitr., a new alien species to the Hungarian flora, was detected between the years 2016–2019. Water bent (P. viridis), originating from the Mediterranean basin, was recorded from several plant nurseries and outdoor flowerpots in Transdanubia, Hungary. The new Hungarian records fit into the observed phenomenon that ornamental plant trade is an important factor in the spread of this species. Morphological characterization and insertion of P. viridis into the Hungarian identification key are also provided in this paper. Since P. viridis was represented in large numbers at some of the Hungarian localities, future monitoring of its spread may be important to evaluate the invasiveness of the species in the country.

  • Ceratocephala testiculata (Crantz) Roth and further data to the flora of the foothills of Bükk Mts.('Bükkalja', NE Hungary)

    This paper reports new floristic data of 367 taxa (365 species and two hybrids) from the foothill region of Bükk Mts. ('Bükkalja', NE-Hungary) based on 5470 field collected data records. The data was collected between 1997–2014 and supplemented with herbaria (altogether 344 herbaria sheets). Data evaluation was based on the comprehensive Bükk Flora of András Vojtkó and further papers. Altogether 45 species were registered as previously unreported from the area, whereas three species had old data (Acer negundoElaeagnus angustifoliaXanthium strumarium). Out of the newly registered species six native species inhabits natural habitats (Carex flaccaCeratocephala testiculataGlycerrhiza echinata, Gypsophila paniculataKochia lanifloraMarrubium vulgare), whereas five species represents the weed flora (Anthemis ruthenicaChenopodium ficifoliumEragrostis pilosaSenecio vernalisXanthium strumarium). The majority of the newly observed species are adventives. Five species were also regarded as recent introduction regionally, although they are native in the country (mostly lowland species: Crypsis alopecuroidesLimonium gmelini subsp. hungaricumSalsola kaliScirpoides holoschoenusTrifolium angulatum). Typical threats observed are landscape and habitat degradation by invasive alien species out of which 11 are newly added. Mass occurrences were detected for the following invasive alien species: Bidens frondosaImpatiens glanduliferaPhytolacca esculentaXanthium italicum. 43 species are also registered, which did not have recently published data from the area. These species include more native elements representing different habitat preferences (dry grasslands, wet meadows, forest and weeds). In case of 65 species the unravelled new occurrences increased significantly, thus contributed to the clarification of their distribution pattern. It was found that the floristic data accumulated on a decade-scale are not sufficient for the analysis of floristic trends, but could serve as a good basis for surveying floristic gradients between the mountainous and lowland areas.

  • The ‘rediscovery’ of the Birdsfoot Fenugreek (Trifolium ornithopodioides (L.) SM.) in the Hortobágy, Hungary

    In 2009, the first author discovered an unknown population of Trifolium ornithopodioides in the Ágota-puszta of Hortobágy plain. In 2016, the second author found an another population in the vicinity of Karcag (Ecse-zug puszta). Up to now there was only one published occurrence of this species from the region. The specimen collected by Szujkó-Lacza Júlia, Kováts Dezső and Fekete Gábor in 1974 was deposited in the herbarium of the Hungarian Natural History Museum (BP), but this incomplete specimen was misidentified, and not Trifolium ornithopodioides. Therefore, this newly discovered site at Ágota-puszta should be regarded as the first trustworthy occurrence of this species at the Hortobágy plain.
