Data to the flora of Hungary I.
254-259Views:80The 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).

Natural values of Mt Somsich near Villány, threatening factors and necessary conservation actions
55–62Views:94Although Mt Somsich is very rich in natural values, it is still a poorly-known part of the Villány Mts. Apart from a few scattered floristic data and a short habitat description, its vegetation is virtually unexplored. The aim of this paper is to characterize the natural and semi-natural habitats of Mt Somsich, give the current population sizes of the protected plant species, survey their threats, and offer suggestions for further conservation activities. Disregarding the totally artificial habitats, five habitat types were distinguished on Mt Somsich, of which the pubescent oak scrub is the most valuable. A total of 15 protected plant species have been reported so far, of which 11 are currently recorded on Mt Somsich. The local wildlife is affected by loss and fragmentation of habitats as well as illegal activities. The negative influences cannot be fully eliminated, but could be minimized.

The herbarium of Debrecen University (DE) I. The “Rezső Soó Herbarium”
142-155Views:218The paper introduces the herbarium of Debrecen University (DE). All specimens of the herbarium were documented by digital photographs, and all data from the labels were entered into an Excel spreadsheet. The largest collection of Herbarium DE, the “Soó Rezső Herbarium” (abbreviation: SRH) consists of ca. 38.000 specimens from almost all European countries, but mainly from Hungary and the neighbouring countries. Most of the specimens originate from Hajdú-Bihar, Pest, Győr-Moson-Sopron, Borsod-Abaúj-Zemplén, Veszprém and Szabolcs-Szatmár-Bereg counties. The SRH stores a considerable amount of original/authentic specimens collected by Hungarian botanists, primarily by Rezső Soó and his followers, as well as Sándor Polgár. The most rapid growth of the SRH took place in the first half of the last century (1930–1950). By contrast, the collection was practically not developed between 1955 and 2000. After the millennium it started to grow again. Data on the most substantial part of the SRH covering native plants collected in the present-day Hungary are summarized in Electronic Appendix 1. (incl. taxon name, settlement, collecting date, collector, file name of documentary photograph).

Bryofloristical study in the Brunszvik manor park in Martonvásár, Hungary
198–206Views:171This is the first bryofloristic study in the Martonvásár manor park. In our survey in 2015, 56 species (6 liverworts and 50 mosses) were found in the park. Most of them are considered to be common in Hungary, but an endangered (Eurhynchium speciosum), a vulnerable (Orthotrichum patens) and five near-threatened species (Aphanorrhegma patens, Orthotrichum obtusifolium, Orthotrichum pumilum, Pseudocrossidium revolutum, Riccia cavernosa) were also found. These results point out the nature conservation value of the manor park.

Data on the distribution of some protected plant species and on their presence in secondary habitats
183-199Views:1828In 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).

The ‘rediscovery’ of the Birdsfoot Fenugreek (Trifolium ornithopodioides (L.) SM.) in the Hortobágy, Hungary
207–212Views:338In 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.

Epipactis exilis in the Börzsöny Mts (C Hungary)
102-103Views:228Seven specimens of Epipactis exilis has been found in the Börzsöny Mts, in a beech forest along the creek Szén-patak on the 21st August 2020. This strictly protected species is very rare in Hungary, the present observation is its fifth occurrence in the country. It is new to the Börzsöny Mts flora.

Asparagus verticillatus L. in Hungary
38-43Views:183Climbing asparagus (Asparagus verticillatus L.) a new adventive species to the Hungarian flora was recently discovered in the city of Pécs (South Hungary) in 2011–2012. Taxonomy, morphological description and current localities of the species are presented in this paper. A. verticillatus is a mediterranean-submediterranean species native in Balkan Peninsula, Eastern Europe, Western- and Middle Asia. The species is a popular ornamental plant in Hungary, but no data was available about its escape or naturalisation in the country so far. Herbarium specimens from Hungary were collected so far mostly from botanical and private gardens; only one specimen was collected in a dry grassland along a roadside in the city, respectively. The newly discovered small populations are located mostly in secondary dry grasslands, at the edges of vineyards and private gardens on the southern slopes of the Mecsek Mts and only one specimen was found far from the residential area in natural vegetation. Because climbing asparagus is a frequently planted ornamental plant in several locations of Pécs, further escape, naturalisation and persistence of the species is possible in the future.

In memoriam Frigyes Ágost Hazslinszky [In Hungarian]
3-7Views:135Mondhatunk-e bármi újdonságot két évszázad távlatában olyasvalakiről, akit kortársai, követői számos alkalommal megemlékezéseikben méltattak? Elfeledett életrajzi dokumentumok vagy a hagyaték feldolgozása nélkül aligha. Hazslinszky Frigyes esetében jelenleg nem állnak rendelkezésünkre az életét és munkásságát új megvilágításba helyező tények, talán mégsem haszontalan feleleveníteni vele kapcsolatos ismereteinket...

Contributions to the flora of Tolna and Baranya counties IV.
17-33Views:203The 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.

In memoriam Palkó Sándor (1959–2002)
179-186Views:186Sándor Palkó (1959–2002) was the first nature conservation surveyor in Zala county at the Balaton-uplands National Park. While he was nation-wide recognized ornithologist, he extended our knowledge with many floristic data too, but we remember him mostly for his imaginative activity in nature conservation. He sent on his experience dozens of young conservationists and stood them on their own ways. His dedication carried with him all those who had predisposition. The Research and Ringing Camp of Fenékpuszta established by him has become one of the most important camps of the country for avian migration research and nature conservation practices.
