A Vértesalja homoki cseres-tölgyesei (Fraxino orno-Quercetum cerridis Kevey 2008)
(2024-07-15) Kevey, Balázs; Riezing, Norbert
Here we evaluate the phytosociological characteristics of the turkey oak forests on sand ( Fraxino orno-Quercetum cerridis ) found at the northern foothills of the Vértes Hills, Hungary. Using the traditional Braun-Blanquet method, 20 vegetation samples were collected and compared with turkey oak forests growing in similar ecological situations in other parts of the country. The traditional and multivariate analyses showed that our samples were quite different from the compared forests, and only the forests in the Bakonyalja and the Pilis Mts showed some similarity with the compared forests. Our samples had the lowest proportion of Quercetea pubescentis-petraeae species among the compared forests, and the highest proportion of specialists ( Corydalis pumila , Daphne laureola , Doronicum hungaricum , Lychnis coronaria , Physocaulis nodosus , Primula veris , Scutellaria columnae , Sorbus domestica and Veratrum nigrum ). The samples were well separated from the compared forests and formed a distinct group.

Botanikai adatok Tolnából és Baranyából IV.
(2024-06-26) Tóth, István Zsolt; Teleki, Balázs
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.

Taxiphyllum densifolium (Taxiphyllaceae) és a mecseki völgyek moharitkaságai
(2024-06-14) Csiky, János; Sipos, Attila
In this paper, we deal with threatened and/or legally protected bryophytes found in the shady, forested valleys of the Mecsek Mountains, which are rare in national and/or local terms. Taxiphyllum densifolium , a rare moss in Europe has stable colonies with sporophytes in two valleys. This study is the first to describe the spore characteristics of this species. The previously considered unique and legally protected Rhynchostegiella teneriffae is nowadays so widespread in the Mecsek that it can no longer be considered a vulnerable species (VU) in Hungary. We present the first population of the legally protected Neckera pennata in Tolna county, and we also report on the recent, unusual occurrence of the data-deficient (DD) Fossombronia wondraczekii . We also list new populations of three other endangered (EN) species, Blindiadelphus recurvatus , Palustriella commutata and Porella arboris-vitae . Several vulnerable (VU) taxa such as Blepharostoma trichophyllum , Porella cordaeana , Sciuro-hypnum flotowianum , Seligeria pusilla , as well as new occurrences of near threatened (NT) mosses such as Microeurhynchium pumilum (with sporophytes), Phaeoceros carolinianus are documented. In addition, the data on Rhynchostegium rotundifolium in Jakab Mountain, which has not been recorded for more than 50 years, is confirmed. The difficulties of differentiating Hygroamblystegium species are briefly discussed.

Multiclavula mucida (Basidiomycota) a Pannon régióban és más adatok a magyarországi lopvanősző flórához
(2023-12-21) Csiky, János; Deme, Judit; Erzberger, Peter; Kovács, Dániel; Németh, Csaba; Sipos, Attila
The 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.

Adatok a Velencei-tó medrének pionír növényzetéhez
(2023-12-21) Riezing, Norbert
Lake Velence is one of Hungary's largest saline lakes. Part of its natural dynamics is that certain parts of the lake bed regularly dry out, providing pioneer surfaces suitable for the emergence of plants of the mudflats and drying (saline) ponds. During the particularly dry year of 2022, the water level was permanently and significantly low, allowing to study the vegetation of the dry lake bed. In the first half of the last century, the natural vegetation of the lakeshore (including salt steppes) was studied, but there are very few records of the pioneer species of the lake bed. The salt steppes around the lake have now largely declined, but due to low water levels, some of their characteristic species are still present in the lake bed (though, usually in low number of individuals). Examples include Crypsis aculeata, Cyperus pannonicus, Suaeda pannonica , the once abundant Suaeda prostrata , and the previously rare Crypsis schoenoides and Spergularia salina. Spergularia maritima was once widespread but currently not found in the lake bed. Although, Schoenoplectus litoralis is not a member of the ephemeral vegetation, but is a characteristic plant of the littoral zone of Lake Velence. This species probably appeared therein the middle of the last century and is currently spreading.

Az apró tyúktaréj (Gagea minima) előfordulása és élőhelyi viszonyai a Sorok-patak mentén (Vas megye)
(2023-12-21) Schmidt, Dávid
Gagea minima (L.) Ker Gawl. is a Eurasian bulbous species. It occurs sporadically in Hungary, but so far only one current occurrence is known from the Western Transdanubia. In recent years, a large metapopulation has been found in a 15 km long section of the Sorok stream. Its habitat is the high sandy bank above the stream, where it lives mostly in nitrophilous vegetation under non-native tree species. Its long-term persistence in this secondary habitat may have been facilitated by its bulbs, which may have been regularly dispersed by periodic disturbance. Myrmecochory may also have played a role in the local establishment of subpopulations. A number of recently found populations indicate that data on the distribution of the species is still incomplete. The lack of data is probably due to its short flowering period and relative inconspicuousness. Gagea minima is considered a valuable relict species in the altered environment of the Sorok stream and its surroundings.

Astragalus vesicarius és más új elemek a Vértes flórájához
(2023-12-21) Bauer, Norbert
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.

Florisztikai adatok Észak-Magyarországról IV. Helleborus dumetorum a Cserhátban és egyéb növény előfordulások
(2023-12-21) Vojtkó, András
In this publication, the author provides occurrences of geobotanical importance from the North Hungarian Mountains collected in the spring of 2023. First occurrence for the following species was recorded: Helleborus dumetorum from the Cserhát Hills, Lunaria annua from the Mátra Mts. and Dryopteris affinis from the Bükk Mts. Ranunculus aquatilis was found again in the Bükk Mts., where it had been collected more than 100 years ago, and Rubus saxatilis was found for the fourth time in the Zemplén Mts.

Adatok néhány adventív növény előfordulásához a Nyugat-Dunántúlon
(2023-12-21) Kulcsár, László
In his publication the author provides data on the occurrence of 11 alien species in Western Transdanubia. Three of these species ( Euphorbia maculata, Euphorbia peplus, Muscari armeniacum ) were observed to have spread rapidly in the past decade. It can be concluded that 4 species ( Artemisia annua, Crocus banaticus, Polycarpon tetraphyllum, Veronica filiformis ) have reached a state which is close to naturalization, while the other reported species ( Euphorbia lathyris, Senecio inaequidens, Silybum marianum, Veronica peregrina ) are casual in this region at present.

Adatok a Malva moschata (Malvaceae) magyarországi szubspontán előfordulásaihoz
(2023-12-21) Somlyay, Lajos
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.

Florisztikai adatok Észak-Magyarországról III. Zempléni-hegység
(2023-12-21) Vojtkó, András; Farkas, Tünde
We 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.

Homoki gyertyános-tölgyesek (Corydali pumilae-Carpinetum) és cseres-tölgyesek (Fraxino orno-Quercetum cerridis) a Pilis lábánál
(2023-04-25) Kevey, Balázs; Bőhm, Éva Irén
We studied the phytosociological characteristics of hornbeam and turkey oak dominated forests growing on sand at the southwestern foot of the Pilis Mountains. Here we present the results of analyses of 10 relevés of each community. The species composition of the hornbeam forest samples is characterized by a relatively high proportion of Fagetalia species. Notable species in the community are Aconitun vulparia , Berberis vulgaris , Epipactis helleborine agg., Galanthus nivalis , Geranium lucidum , Lilium martagon , Omphalodes scorpioides , Piptatherum virescens , Primula veris , Scilla vindobonensis , Sorbus aria agg . , S. domestica , Veratrum nigrum , and Waldsteinia geoides. In the turkey oak forests, species characteristic of the class Quercetea pubescentis-petraeae have the highest proportion. Notable and locally typical species occurring in the community are Anthericum ramosum , Digitalis grandiflora , Iris variegata , Piptatherum virescens , Primula veris , Achillea distans , Dictamnus albus , Galanthus nivalis , Lonicera xylosteum , Scilla vindobonensis , Sorbus domestica , Veratrum nigrum , as well as Lunaria annua and Tilia tomentosa that are possibly introduced here. Based on the results of statistical analyses, the two forest communities are best identified with the associations named Corydali pumilae-Carpinetum and Fraxino orno-Quercetum cerridis , both occurring in the Transdanubian Mountain Range.

Our 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.

Szikes területek elterjedése és flórája a Mezőföldön
(2023-04-21) Lendvai, Gábor
Areas with alkaline and saline (solonetz and solonchak) soils occupy substantial areas in the westernmost, Transdanubian part of the Great Hungarian Plain (Mezőföld). To this date, the flora and vegetation of only two localities have been studied in some detail, while the rest has remained largely unknown in this respect. In this paper, I provide brief descriptions of these little-known areas and present a list of halophytes with distribution data from the last 17 years. The names of the plants are followed by the name of the township and the geographical location where the plant was found, the code of the grid cell of the Central European Flora Survey grid that includes the location, and in selected species, the year when the species was first recorded. The list is arranged in alphabetical order irrespective of taxonomy. The occurrence data indicate that the floras of these saline-alkaline areas represent only subsets of, but in combination are almost identical to the overall flora of similar habitats in the Sárvíz plain.

Nyárfaültetvények orchideái – irodalmi áttekintés
(2022-07-12) Molnár V., Attila; Süveges, Kristóf; Fekete, Réka; Archaux, Fréderic; Chevalier, Richard; Takács, Attila
There are literature data on the occurrence of 26 orchid species and 2 hybrids in economic poplar plantations from 13 European countries. The occurrence of 4 additional species in poplar plantations in 3 countries is proved by sources on the World Wide Web. The most widespread orchids in the poplar plantations are the rhizomatous, partial myco-heterotroph Cephalanthera and Epipactis species. Their importance is enhanced by the fact that most of the known populations of some species with a relatively narrow distribution range ( Epipactis bugacensis, E. campeadorii, E. fibri, E. tallosii, E. zaupolensis ) are known in poplar plantations. Cultivated poplar monocultures are likely to provide habitat for further orchids in other countries too. Most of the published papers are limited to floristic data from a single or a few plantations. Longer-term observations are only available from Poland, thanks to the work of W. Adamowski, and these suggest that populations may persist for decades and even increase dynamically. The size of orchid populations in some cases can reach thousands or even hundreds of thousands of individuals. Orchids can appear earliest in (4–)7–8 years old plantations. Very little is known about how the cultivation, structure, soil conditions and the poplar cultivars influence the presence of orchids. Mycorrhizal interactions of poplars and orchids may play a key role in this process, but the available knowledge is very limited. Furthermore, little is known about how the economic use of plantations can be reconciled with the long-term maintenance of orchid populations.

Adatok a Dél-Nyírség és peremterületei flórájához
(2022-07-07) Lovas-Kiss, Ádám; Süveges, Kristóf
In 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.

Szombathely város kámoni és herényi vízbázis-védőterülete, mint növényzeti értékek menedéke
(2022-03-07) Balogh, Lajos; Szinetár, Csaba
The hay meadows and protective forest strips of the Kámon and Herény source water protection areas in the northwestern part of Szombathely have been in good natural condition for decades. By harbouring populations of protected plant species ( Orchis morio , Pyrola rotundifolia , Cephalanthera longifolia , Epipactis helleborine and Ophioglossum vulgatum ), these areas resemble natural habitats found nearby in the Kőszeg Mountains and the Őrség National Park. The good semi-natural condition can be attributed to the lack of regular mowing in the case of meadows and the lack of disturbance in the case of forest strips. In recent years, however, the area have been exposed to increasing human disturbance (car and motorcycle off-roading), so it may be timely to initiate legal protection. This short case study indicates that properly managed source water protection areas can play an important role in the conservation of semi-natural habitats, rare and protected plant species and the associated fauna.

A kúszó csalán (Urtica kioviensis) előfordulásai a Dél-Nyírségben
(2022-08-04) Demeter, László; Szél, László
So far, only one herbarium data and one flora mapping data on Kievan nettle ( Urtica kioviensis Rogow.) has been known from the Southern Nyírség. Since 2004, the species has been detected in 14 flora mapping quadrats. Its data were also collected in winter because its habitats are more easily accessible on ice, its overwintering shoots are more noticeable, and they are strikingly morphologically different from the great nettle ( Urtica dioica L.). Typical habitats were willow carrs ( Calamagrosti-Salicetum cinereae ), reeds ( Phragmitetum communis ), rush-beds ( Typhetum latifoliae , Typhetum angustifoliae ), tufted sedge communities ( Caricetum elatae ) and tall sedge meadows (mainly Caricetum acutiformis ). The largest stocks live in reservoirs in secondary habitats. A significant part of the stocks is located in the wide valleys of the main watercourses in the area.
