  • Astragalus vesicarius and other new taxa to the flora of the Vértes Mountains (Hungary, Transdanubian Mts)
    195–199

    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.

    Munkakapcsolatunk látszólag igen rövid ideig tartott. Az ő 15 éves, vízügynél befutott pályája és az én vele egy munkahelyen töltött három évem (csak 1977 októbere és 1980 szeptembere között dolgoztunk együtt) nevetségesen csekély idő-átfedés. Ennek ellenére – pláne mai szemmel nézve – ez igen-igen speciális időszak volt, amikor még kézzel írtuk a jelentéseinket, valamint írógéppel, megfelelő határozókönyvek híján, számítógép nélkül dolgoztunk, nekem tereptapasztalataim még egyáltalán nem voltak, vizeink élővilágát csekély módon ismertem csak, s a környezetszennyezés durvábbnál durvább eseteivel sem igen találkoztam. Egy mérnöki szemlélet által uralt kutatóintézeti közegben kezdtem a munkát, a hazai vizek átfogó feltárásáról  még nem esett sok szó, és meg lehet említeni – az akkori KGST-kapcsolatok ellenére – a bizonyos fokú nemzetközi elszigeteltségünket is. Felföldy Lajossal ekkor találkozhattam és dolgozhattam együtt. Ő volt az a kutató, akitől kollegáimmal elsajátíthattuk a hidrobiológiai szemléletmódot, a környezet- és természetvédelem szeretetét és ápolását, a magas fokú szakmaiságot...

  • Multiclavula mucida (Basidiomycota) and other cryptogamic taxa in the Hungarian flora

    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.

    László Almádi, the 80 years old professor at the Georgikon Faculty of Keszthely University, has a several decades long history in teaching. During this period, he taught a large number of students in agriculture with an up-to-date agrobotanical knowledge, and launched the career of or had a great impact on many field botanists working in nature conservation. His ability to identify plants is excellent, and he did pass this knowledge on. Besides his huge fascination for plants, his precision, broad and well-founded knowledge serve exemplary for us. Professor Almádi’s rich life is presented in this tribute paper based on his personal stories and written publications, and is supplemented with our own memories, experiences. We cordially greet our Professor on the occasion of his birthday!

  • Data on the distribution of some protected plant species and on their presence in secondary habitats

    In this paper, I publish my floristic data on some protected and strictly protected plant species collected in Hungary between 2016 and 2021. The data published in this paper cover 31 micro regions of Hungary, but most of them come from the Great Hungarian Plain, especially from Pest and Bács-Kiskun counties. I describe the occurrences of 41 protected and three strictly protected vascular plant species (two ferns and 42 flowering plants), some of which represent new data for the particular micro region or even larger geographical areas (e.g. Botrychium matricariifolium, Thlaspi alliaceum and Nasturtium officinale). For some species, the published data either come from floristically understudied areas (e.g. Ranunculus illyricus, Vinca herbacea and Cardamine amara) or are considered rare in the certain region and/or in the whole country (e.g. Apium repens, Cnidium dubium and Vicia narbonensis). For other species, the newly reported occurrences are presented as complement to the already known distribution data (e.g. Cephalanthera damasonium, C. rubra, Linaria biebersteinii, Sonchus palustris and Agrostemma githago). In support of the nature conservation actions, I provide data from the flora of some floristically understudied micro regions (e.g. Dorozsma-Majsai Sand Ridge, Bácskai Loess Plain) and try to highlight the role of canals in Hungary in species and biodiversity conservation, by the example of the Danube-Tisza canal. In this manuscript, I publish data on twelve protected plant species from the Danube-Tisza canal and its canal bank (eg. Peucedanum palustre, Carex paniculata, Clematis integrifolia).

  • Rediscovery of Gymnadenia frivaldii Hampe ex Griseb. at its northern distribution limit (Eastern Carpathians, Romania)

    Frivald’s Gymnadenia is a very rare Balkan species in the South-Eastern Carpathians. The specific epithet “frivaldii” honours Imre Frivaldszky (1799–1870), a Hungarian naturalist. The species occurs in the drawdown zone of mountain fens of the Balkan Peninsula (Bulgaria, Romania, Greece, Macedonia, Montenegro, Albania), at elevations between 1000 and 2300 m. In the Carpathians the species was first reported from the Ţarcu Mts (Southern Carpathians) by János Heuffel. In 1874 Simonkai collected a specimen (BP 33967) in the Retezat Mts, but he was uncertain about its identity, thus this record eventually appeared as G. albida (Pseudorchis albida) in his monograph. Since then the species has been found at several localities in both the Retezat Mts (Mt Peleaga, Zănoaga, Zănoguţa, Ana and Bucura glacial lakes, Judele Valley) and the Ţarcu Mts. This paper reports on the discovery of Frivald’s Gymnadenia in the area of “Szökő-láp” (Harghita Mts, Eastern Carpathians), which can be considered a confirmation of the old literature record. This is the northernmost locality of this Balkan species known so far. The chorology and conservation status of G. frivaldii in the South-Eastern Carpathians are discussed.

    Kurgans are ancient burial mounds built by nomadic steppic cultures. Embedded in the heavily transformed landscapes of the Carpathian Basin they often serve as last refuges for rare and endangered plant species. In our paper we publish floristic data collected on 82 kurgans located in the area of the Hortobágy National Park Directorate. Our dataset covers 64 CEU quarter quadrates, and the territory of 45 settlements. We provide data on 39 taxa that are either protected (e.g. Anchusa barrelieriCentaurea solstitialisRanunculus illyricus and Phlomis tuberosa) or regionally rare (e.g. Aegilops cylindricaAstragalus austriacusGlaucium corniculatum and Trifolium diffusum). Our records demonstrate that kurgans have a vital role in maintaining the populations of rare and endangered grassland species even in transformed landscapes.

    Lesser Plain (Kisalföld) – divided among three countries (Austria, Hungary and Slovakia) – is the westernmost part of the lowland areas of the Pannonian Basin. Present paper provides a résumé of the authors’ floristic work from the Hungarian part of the area, describing localities, habitats and regional phytogeography of 57 taxa altogether. The localities were listed according to the classification of small geographic regions. The most important results of the study are as follows:

    • We recorded 5 species new to the region (Brachypodium rupestre, Bromus ramosusHypericum dubiumLathyrus sphaericus, Tordylium maximum); all of them can be considered as submontane-montane elements.
    • We reported several species new to a microregion within the Lesser Plain: montane species in the W-SW part of the Plain (Cirsium rivulareDryopteris dilatataEquisetum telmateia), loess-connected species mainly on the Moson Plateau (Agropyron cristatumAllium atroviolaceumEuphorbia salicifoliaViola ambigua); and occurrences of species on sandy soils near the Lake Fertő (Draba nemorosaStipa pennata).
    • We explained the known localities of several salt tolerant species (e.g. Carex divisaCrypsis alopecuroidesJuncus maritimusLimonium gmeliniiSuaeda pannonica) from the Lake Fertő and its surroundings.
    • We assessed the role of the forest management and nature conservational actions in the distribution of some important tree species (Acer tataricumBetula pubescensFraxinus ornusQuercus petraea, Salix pentandra).
    • We discussed the regional nature conservational status of several protected and/or threatened species (e.g. Allium carinatumAllium suaveolensCarex strigosaHottonia palustris, Potamogeton coloratus, Stellaria palustris) in the Lesser Plain.

    The activities of the authors in the surroundings of Győr were supported by monitoring results gained during the Hungarian Little Plain project (LIFE08 NAT/H/000289).

  • Dactylorhiza traunsteineri (Saut. ex Rchb.) Soó: an unexpected record in the Romanian flora

    Dactylorhiza Necker ex Nevski is a complex genus. The taxonomy of these dactylorchids is widely considered to be complicated due to relatively high morphological variability within species and high frequency of hybridization between species. During a floristic survey of the Valea Morii (Morii Valley, Malomvölgy) Nature Reserve in June 2017, a population of Dactylorhiza traunsteineri (Saut. ex. Rchb.) Soó, a species with uncertain presence in the Romanian flora was found. In the Morii Valley, this narrow-leaved marsh-orchid was encountered in fen-patches, in phytocoenoses of the plant association Orchido-Schoenetum nigricantis Oberd. 1957. Due to the cool and wet microclimate of the Morii Valley, many glacial relicts and other plant rarities (e.g. Tofieldia calyculata (L.) Wahlenb., Swertia perennis (L.), Liparis loeselii (L.) Rich., Ophioglossum vulgatum L. Schoenus nigricans L.) had been able to survive on strongly humid places on calcareous soils. This study reports the first occurrence of D. traunsteineri in Romania confirming the presence of a highly debated taxon. We also discuss the morphological features, habitat preference and conservation status of this new species in the Romanian Flora.

  • Taxiphyllum densifolium (Taxiphyllaceae) and other rare bryophytes of the Mecsek valleys (SW Hungary)

    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.

    This paper presents five new localities of the rare and threatened orchid Himantoglossum adriaticum in Zala county. The new localities falls within the known distribution area of the species. The population size on newly found locations are extremely small, in most cases only 1 generative individual were observed in the mesophilic secondary grasslands of abandoned vineyards. Highly possible, that this species shows a slow, but detectable expansion in Hungary, maybe due to recent climate change process.

    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.
