Tétel Szabadon hozzáférhető Adatok a Dél-Nyírség és peremterületei flórájához(2022-07-07) Lovas-Kiss, Ádám; Süveges, KristófIn 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.Tétel Szabadon hozzáférhető Adatok a vasútmenti pionír élőhelyek flórájához a Tiszántúlon(2022-03-07) Kis, SzabolcsVerges 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.Tétel Szabadon hozzáférhető Adatok Magyarország flórájához I.(2014-07-01) Kovács, DánielThe paper gives new floristic data from several regions of Hungary. Some of them are recent evidences of old data (e.g. Herniaria incana in Pomáz), others are new occurrences of recently expanding alien species (e.g. Eleusine indica, Geranium purpureum, Typha laxmannii), casual species (e.g. Lobularia maritima, Nepeta racemosa) or legally protected taxa (e.g. Agrostemma githago, Ornithogalum brevistylum, Ranunculus illyricus, Sonchus palustris).Tétel Szabadon hozzáférhető Ceratocephala testiculata (Crantz) Roth és további adatok a Bükkalja flórájához(2015-01-01) Schmotzer, AndrásThis 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 negundo , Elaeagnus angustifolia , Xanthium strumarium ). Out of the newly registered species six native species inhabits natural habitats ( Carex flacca , Ceratocephala testiculata , Glycerrhiza echinata , Gypsophila paniculata , Kochia laniflora , Marrubium vulgare ), whereas five species represents the weed flora ( Anthemis ruthenica , Chenopodium ficifolium , Eragrostis pilosa , Senecio vernalis , Xanthium 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 alopecuroides , Limonium gmelini subsp. hungaricum , Salsola kali , Scirpoides holoschoenus , Trifolium 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 frondosa , Impatiens glandulifera , Phytolacca esculenta , Xanthium 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.Tétel Szabadon hozzáférhető A Cyperus odoratus Magyarországon(2021-09-24) Mesterházy, AttilaEleven species of the genus Cyperus have been reported from Hungary so far, of which 3 are certainly aliens. A small population of C. odoratus , new for the flora of Hungary, was found along the River Danube near Foktő settlement (Bács-Kiskun County, S Hungary) in late autumn of 2019. On this occasion blooming specimens were observed in the floodplain ruderal vegetation on the bank of a fork of the Danube. This species is widespread in the tropical and subtropical regions of the World, and was first introduced to Europe in the early 1950s. More recently it has been spreading along certain rivers of Italy and Spain. It was discovered along the river Danube in Romania in the early 1990s, and later at the upper parts of the river in Bulgaria, Croatia and Serbia. Its introduction into Hungary is connected with the Danube, too. Based on foreign experience, it is probable that C. odoratus will be spreading along the Hungarian Danube system, hopefully, not as an invasive species.Tétel Szabadon hozzáférhető Florisztikai adatok a Tiszántúl északi pereméről(2014-07-01) Takács, Attila; Zákány, Albert; Gulyás, Gergely; Koscsó, János; Sramkó, GáborThis 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).Tétel Szabadon hozzáférhető Kiegészítések a Nyugat-Dunántúl flórájának ismeretéhez(2015-07-01) Mesterházy, Attila; Kulcsár, LászlóIn 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.Tétel Szabadon hozzáférhető Magyarországon előforduló idegenhonos tóalma (Ludwigia) fajok taxonómiai revíziója(2019-07-01) Mesterházy, Attila; Riezing, Norbert; Vidéki, RóbertSome 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.
