    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.

    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.

    In the legacy of Sándor Jávorka deposited in the Hungarian Natural History Museum there is a 12-page typescript entitled “An identification key for Hungarian botanists portrayed in Album Kleinianum (Budapest, 25 September 1912)”. It provides accurate descriptions of 50 botanists in the form of an identification key, which was compiled by Zoltán Szabó, a well-known botanist at that time. The most important features of each person are presented in a humorous, basically ironic, funny and witty way. The Identification key was prepared for the session no. 178 of the Botanical Section of the Royal Hungarian Natural Science Society, where another botanist, Gyula Klein was congratulated on the 40th anniversary of his teaching profession as well as the 20th anniversary of his membership in the society. Almost all prominent botanists attended the meeting. This paper presents the Identification key, supplied with annotations and photographs.

  • New data on the Hungarian adventive flora: Acer opalus Mill. subsp. obtusatum (Waldst. et Kit. ex Willd.) Gams 1925 in Hungary
    229-238
    Views:

    Acer opalus Miller 1768 because of its complex taxonomic status can be interpreted as a collective species which contains several species and subspecies depending on different interpretations. An important adventive occurrence from this collective species was found in a forest that belongs to the Tétényi plateau (Budapest, 11th district) in July of 2009. It is proved to be Acer opalus Mill. subsp. obtusatum (Waldst. et Kit. ex Wild.) Gams. The natural range of the subspecies covers the eastern side of the central Mediterranean Sea region and western Balkan Peninsula. It is a submediterranean-mediterranean, thermophile, shade-tolerant taxon but often appears together lightdemanding species too. In its native range it occurs in beech, pine, sessile oak forests and in different types of dry oak forests as admixed tree species. The subspecies was found in a turkey oak – sessile oak community in Hungary. Several old, seed growing individuals live on the spot which have had continuous seed production. Therefore from the old trees to the young seedlings different age categories are represented.

  • Rubus armeniacus Focke, an unnoticed invader in the Hungarian flora

    The authors report on the occurrence, distribution and invasion potential of Rubus armeniacus, a bramble species of Caucasian origin, in Hungary. The first verified records of the species are from the 1990s. It has established strong populations in ruderal habitats mainly around Budapest and some other cities, whereas its competiveness is rather weak in closed non-lowland forests rich in native bramble species. In terms of conservation, it constitutes a real threat to the vegetation of Pannonian sandy habitats. The results of this study also emphasize the importance of recognising "nonnative cryptic species" for ecology and conservation biology.

    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.

  • Spreading along the railways: morphology and invasion success of Vulpia ciliata in Hungary
    145–156
    Views:
    524

    Vulpia ciliata Dumort, a widespread species in the Mediterranean region, has been introduced in several European countries in recent decades, mainly along railways. The species was first discovered in Hungary at Szolnok railway station in May 2016, then a few days later at Keleti railway station in Budapest. In 2020 the species was found in several Transdanubian railway stations. Apparently, V. ciliata has recently been established in numerous parts of the country, probably spreading by railway transport. Until now, the species has only been found in the vicinity of regularly used tracks (in a distance of 20 m at the most). Being an invasive alien species, V. ciliata can displace the native Vulpia myuros in ruderal vegetation along railway lines. The species can easily be distinguished from V. myuros by its hairy lemma. Moreover, it flowers earlier than the other two indigenous species in Hungary, often already in late April. Based on the characteristics examined (number of nodes in the upper 2 cm zone of the rachis, number of fruits per spikelet, rate of fertile and sterile florets within the spikelet, lower and upper glume length, lemma and awn length separately, rachis width in the upper 2 cm zone) we have concluded that V. bromoides and V. myuros are less different from each other than V. ciliata from these two species. In the case of V. ciliata subsp. ciliata, we observed that spikelets (detached from the inflorescens) function as dispersal units. Therefore we assume that the observed low fertility rate within the spikelets, as well as the presence of marginal cilia on lemmas promote the spreading success of V. ciliata (spreading in clusters, anemochory, zoochory, anthropochory). Its early maturation (in May) can also facilitate its spread along railways, because the populations survive the chemical weed control usually carried out in late spring. The other two Hungarian species usually ripen later (in June). For the time being, the spread of V. ciliata outside the Hungarian railway network may be hindered by climatic conditions, or by the lack of seasonal weed control outside that network, which otherwise offers a relative survival advantage for V. ciliata along railway tracks.

  • Monitoring of the Apium repens population near Császártöltés (2006–2015)

    Detailed botanical surveys were carried out to monitor the population size of Apium repens in the Vörös-mocsár nature protection area (located in S Hungary, Császártöltés). We found a clear correlation between the water status and the land use type and management of the habitats and the size of the Apium repens population. Apium repens is a Nanocyperion-species, which simultaneously requires wet and open surfaces. Its population shrinks, becomes latent or disappears if its habitat dries out or any other radical transformation happens, like too much leaf litter, closure of the vegetation, or succession on the open peat surfaces. Proper management (water retention, extensive grazing, mowing, open peat surface) has a very positive effect on the populations in a short time, even within a growing season. The research was implemented within the framework of the National Biodiversity Monitoring System, in cooperation with the Kiskunság National Park Directorate.

    The paper introduces the “Zoltán Siroki Herbarium” (on the basis of the MS Excel spreadsheet database of the collection) which is a separate section within the Herbarium of Debrecen University (DE). The Zoltán Siroki Herbarium consists of ca. 20 000 specimens from almost all European countries, but mainly from the historical territory of Hungary. Although ca. 400 botanists contributed to this collection, most of the specimens were collected by Zoltán Siroki in Hajdú-Bihar, Pest and Borsod-Abaúj-Zemplén counties. The most rapid growth of the Herbarium took place in the middle of the last century (from the 1940s to 1960s), but Siroki remained an active collector until the 1980s. Some specimens from the Herbarium of former Royal Seed Testing Station (Budapest) was also incorporated in this collection; they represent gatherings from the last decades of  the 19th century and first decades of the 20th century. Data on the most significant part of the collection, representing native plants collected in the present-day Hungary, are summarized in Electronic Appendix 1. (incl. taxon name, settlement, collecting year, collector, file name of documentary photograph).

    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!
