    Dr. Antal Waisbecker (1835–1916) was a Hungarian physician and the most prominent botanist of Vas county (West Hungary) at the turn of the 19–20th century. He contributed with important floristic data for the botanical monography of Vas county, authored by Vince Borbás. He processed the pteridophytes of Vas county and cormophytes in the surroundings of Kőszeg. Antal Waisbecker was an expert in the knowledge of sedges too. He discovered and described the Carex fritschii. Remarkable amount of herbarium specimens collected by Waisbecker are deposited at the Savaria Museum (Szombathely, SAMU) and Hungarian Natural History Museum (Budapest, BP).

  • About the occurrence of Spiraea media Fr. Schm. on the Balaton Uplands

    The presence of Spiraea media on the Balaton Uplands has high plant geographical importance, but the found location has not been known before its recent rediscovery. The Spiraea media was discovered on the Kopasz Hill (Felsőörs) growing in a closed Quercus cerris oak forest (~Fraxino orni-Quercetum cerridis); which is a rather atypical habitat of the species. The appearance of blooming specimens and the rediscovery of the species is probably due to the cut of the neighbouring forest, which has resulted extra irradiation in the area. The 19th century military maps of the landscape show that the former vegetation of the area was characterised by the mosaics of rocky grassland–scrub–forest or rocky scrub rich patches being suitable for the species.

    Lajos Felföldy (1920–2016) was one of the most versatile and open-minded Hungarian biologists. He began his scientific career as a student of Prof. Rezső Soó. Between 1938 and 1946 he participated in geobotanical studies in University of Debrecen and Kolozsvár (Cluj-Napoca, Romania). He contributed with important achievements to the development of several biological disciplines. His pioneering study on the effects of air pollution on epiphytic lichens (1942) was among the firsts in the world. He described Hemitherophyte life-form as a discrete unit within Raunkiaer's plant life-form system (1942). He was a pioneer in the cytological (caryological) study of wild vascular plant species in Hungary (1947–1949). His results regarding to primary production of freshwater algae and algal culture (1958–1960) were in leading edge. In 1972 he founded and until 1990 edited the Hungarian series entitled ‘Vízűgyi Hidrobiológia’. Books of this series aimed to publish identification keys of freshwater taxa. These books were proved to be decisive and useful tools for Hungarian hydrobiologists in biological classification of brooks, streams, rivers and different types of stagnant waters. Between 1934 and 2009 he collected more than ten thousand herbarium sheets. After his retirement, he dealt with the revision of the herbarium material of Department of Botany in Hungarian Natural History Museum and Botanical Garden of Eötvös University (Budapest). He participated in the preparation of the New Hungarian Herbal. His scientific work was characterised by deep humility for nature, which was founded on strong theoretical and practical background.

  • Rediscovery of Crepis mollis (Jacq.) Asch. subsp. hieracioides (Waldst. & Kit.) Domin in Hungary

    Crepis hieracioides (= C. mollis subsp. hieracioides) was described from the Bakony Mts. (Western Hungary) by Pál Kitaibel more than 200 years ago. His record has been the single one of this taxon from the territory of present-day Hungary thus far. In the second half of the 20th century this taxon was either reported as ‘extinct’ or was plainly ignored in the Hungarian literature. This paper reports about the recent rediscovery of C. mollis subsp. hieracioides in the Bakony Mts., specifically in the ‘Bakonyalja’ region (Devecser: Széki-erdő). The habitat is characterised, and the regional phytogeographical significance of this taxon is emphasised.

    The present paper is the 13th in a series of papers contributing new floristic data to complement the distribution maps of Atlas Florae Hungariae. We present altogether 1307 new occurrence data to advance our knowledge of the distribution of vascular plants in Hungary. New data are presented for 634 vascular plant species from 256 flora mapping quarter quadrates (CEU). Due to the unevenness of data collection, the data are highly dispersed over the area of Hungary. Most of the presented occurrence data are from the Great Hungarian Plain, the North Hungarian Mountains, and the Little Hungarian Plain regions. The enumeration includes rare native species (e.g., Androsace maxima, Erysimum crepidifolium, Orobanche gracilis, Peucedanum palustre, Pulsatilla zimmermannii, Scopolia carniolica, Vicia biennis), rare or data deficient adventive species (e.g., Euphorbia prostrata, Euphorbia serpens, Lindernia dubia), subspontaneous occurrences of native species (Asplenium scolopendrium, Daphne laureola, Chenopodium opulifolium), species spreading along linear infrastructure (Eleusine indica, Plantago coronopus, Sorghum halepense, Spergularia salina, Tragus racemosus), and also common native species with data deficient distribution maps (Agrostis stolonifera, Bromus benekenii, Bromus japonicus, Carex caryophyllea, Carex divulsa subsp. divulsa, Equisetum ramosissimum, Vulpia myuros).

    Malva moschata is an alien species in Hungary, seldom cultivated as garden ornamental plant. Although considered as occasional escapee from cultivation, Hungarian literature has only cited Budapest as an example of such cases thus far. During a revision of the Malva collection in BP herbarium, several specimens were traced (mostly erroneously labelled as Malva alcea) which demonstrate subspontaneous occurrences of the species, primarily from the Transdanubian region (Hungary). The vouchers are hereby listed, arranged in alphabetical order of localities (settlements). Literary connections, if relevant, are briefly discussed.

    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. platycarposErodium ciconiumLappula squarrosaMelica transsilvanicaPapaver 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).

    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.

    A conservation survey on the condition of steppe and forest-steppe habitats in the Vértes Mts revealed several plant species from the flora of the area that have not been reported before. From a phytogeographical point of view, the most important is Astragalus vesicarius, whose small population in the Vértes fits very well into the native distribution pattern of the species in Hungary. Another important steppe plant is Stipa dasyphylla, which is found in two locations in the Vértes Mts. Besides other taxa of conservation interest (Orobanche teucrii, Phelipanche purpurea, Rosa hungarica), some under-recorded species (Cerastium tenoreanum, Stellaria pallida), and some spreading weeds (Elymus elongatus, Euphorbia lathyris) enrich our knowledge of the flora of the area.

    A recent floristic mapping of the Velence Hills has clarified the local distribution of many plant species. This study presents records of 219 phytogeographically significant or sporadic/rare taxa (216 species/subspecies and 3 natural hybrids). The local distribution of some species representing typical regional distribution patterns (Alyssum turkestanicum, Artemisia austriaca, Bupleurum pachnospermum, Doronicum hungaricum, Hypericum elegans, Lathyrus sphaericus, Minuartia viscosa, Ornithogalum comosum, Scabiosa canescens, Sedum caespitosum, Sternbergia colchiciflora, Vinca herbacea) are shown on maps. More than fifty taxa previously unknown from the area were recorded during the floristic mapping, including phytogeographically significant ones, such as Bassia laniflora, Brassica elongata, Bupleurum praealtum, Centunculus minimus, Hypericum elegans, Orlaya grandiflora, Phleum bertolonii, Silene dichotoma, Stipa tirsa, Tordylium maximum, Trifolium diffusum, T. ochroleucon and Valeriana dioica. In terms of phytogeography, the Velence Hills can primarily be characterised by the co-existence of continental and sub-Mediterranean elements as well as species of acidophil and strongly basic habitats.

  • Contributions to the distribution of Arabis nemorensis (Cruciferae) in Hungary
    155-169
    Views:
    102

    Arabis nemorensis is a poorly-known species with sparse and mostly uncertain literature records in Hungary. A complete list of its known occurrences was presented in Soó’s synopsis in 1968. A few new records of this taxon have been reported since then. In the present study all literature records were evaluated by means of revision of Hungarian herbarium materials. Several vouchers were succesfully traced, and their identity as A. nemorensis was confirmed (Baja, Ercsi, Lesenceistvánd, Miskolc, Nagykanizsa, Szigetújfalu). In other cases, the putative vouchers belonged to A. hirsuta or A. sagitatta, thus the corresponding literature records proved to be erroneous (Balatonmáriafürdő-alsó, Gyenesdiás, Kőszeg, Vasboldogasszony, Zalaújlak). On the other hand, hitherto unknown Hungarian localities of A. nemorensis were revealed, specifically in the Bükk Mts. (Eger, Kács), the Bakony Mts. (Márkó), in the western Balaton region (Hahót, Hévíz, Keszthely-Fenékpuszta, Nyirád, Tapolca) and the Hungarian Plains (Csákvár, Debrecen, Egeralja, Fertőd-Eszterháza, Kiskőrös, Lébény, Ócsa, Sárszentmihály, Szigetszentmiklós). The species appeared to be new for the phytogeographical regions Bakonyicum and Nyírségense. Additionally, a few specimens of A. nemorensis collected outside the territory of present-day Hungary were revised in BP. The historical occurrence of the species at Torja (Turia in Romania) is documented by two specimens (Schur, 1853, as A. gerardi; Jávorka & Keller, 1943, as A. hirsuta). Another specimen that was collected in 1879 at Óbecse (Bečej) and labelled as A. glastifolia by Kovács was found to be A. nemorensis too. Since the identity of Schneller’s literature record (1858) from Futak is uncertain, Kovács’s specimen is currently the only, though historical record of this species from Vojvodina province in Serbia. Further specimens of A. nemorensis were discovered in the collections of Lengyel. They were collected and labelled as A. sagittata near Pomogy (Pamhagen) in 1910 (and questionably in 1919), probably representing the first gathering of A. nemorensis from Burgenland state in Austria.

  • Cardamine occulta Hornem. in Hungary, and other stowaways of the ornamental plant trade

    During 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.

    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.

  • New occurences and spread of the adventive species, Torilis nodosa in Hungary

    Views:
    655

    Torilis nodosa (L.) Gaertn. is an Atlantic-Mediterranean weed species. Its old data are known from Budapest, but these may have been occasional occurrences, the species has not been confirmed in Hungary for more than a hundred years. In the last few years, we have found six new occurrences of the species in Hungary, one population in Budapest, and another five in some settlements on the northern shore of Lake Balaton. The species was observed in ruderal or intensely mowed urban habitats, in all cases. Intensive tourism has a role in its introduction for sure, but for the survival of self-sustaining stands and in its already perceptible regional spreading, the climate change trends, the increasingly mild winters, and the decreasing number of frost days could also be important. New data from Hungary are well connected to its other Central European observations.

  • Continuing spread of Plantago coronopus along Hungarian roads
    19–26
    Views:
    520

    In the course of our research of Hungarian transport routes, we observed an intensive spread of the Atlantic-Mediterranean Plantago coronopus L., a recently established species in Hungary. Between 2017 and 2019, it was detected in 47 flora mapping quadrats, which increased the total number of occurrences to 81 since 2013. Besides motorways, the main Hungarian transport routes were involved as well. 26 occurrences have been recorded along the roads 4/E60, E573, 8/E66, 86/E65 and 87, which are severely affected by international traffic. However, on routes avoiding international transit traffic, the species’ occurrences are still rare. In some cases, the predominant direction of traffic appeared to influence the formation of new stands. It is very likely that the first individuals that appeared along the section of the M86/E65 motorway between Szombathely and Hegyfalu in 2019, arrived primarily by northbound traffic, rather than along the road 86, which runs parallel to it only a few hundred meters away. Likewise, it seems certain that the spread of the species along the roads M1/E60, E75 (Mocsa, Tata, Páty) and M7/E71 (Fonyód, Balatonlelle, Kajászó) as well as the road 8/E66 (Bakonygyepes, Veszprém) is due to reproduction of older extensive local populations. At several localities along the outer bend of roundabouts or near the exits of motorways, a dispersal role of intense winter road salting was also observed. The largest populations were located mostly along ditches, next to the (often bare) lane of roadbeds that are heavily affected by mechanical and osmotic stress. The majority of stands were found within a 3 meters wide belt along the asphalt strip (5 meters was measured in the lawn of a cemetery once). Since the species is present continuously at several localities since 2013, it is considered as naturalised in Hungary, and its further spread can be confidently predicted. The current status of the species in Hungary is naturalised (non-trans¬former) neophyte.
