New data to spreading of Plantago coronopus in Hungary
99-101Views:273In this study, new data of the naturalized roadside alien Plantago coronopus L. found in 2020 are listed. Numerous stands have been detected at sites far from previously known localities. These data show that P. coronopus is still in an intense phase of its spread. The species currently known from 90 flora mapping units in Hungary. Its new observations come from the narrow vegetation strip along roadsides, with the exception of the new data from Szombathely, which comes from the parking lot of a shopping center.

The Herbarium of Debrecen University (DE) II.: The „Zoltán Siroki Herbarium”
15-22Views:435The 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).

Data on the occurrence of sedge species (Carex, Cyperaceae) in and around South Nyírség (East Hungary)
165-198Views:412We provide floristic data on a total of 38 sedge species in the area of South Nyírség and its immediate surroundings. We also detected some populations of previously undescribed or rare species in the Hungarian Great Plain, such as Carex buxbaumii, Carex hartmanii, Carex umbrosa, and Carex paniculata. We report several new occurrences of species with little literature data from the area, such as Carex brizoides, Carex michelii, Carex pallescens, Carex elongata. However, during the last 13 years, we were not able to detect seven species previously mentioned in the literature. Herbarium data confirmed that some of the older Carex nigra occurrences for the area actually refer to Carex cespitosa. Based on herbarium data and the literature, we think that local data on Carex pairaei may largely refer to Carex divulsa subsp. leersii and/or Carex spicata. Contrary to many pieces of literature, Carex vulpina was not observed inside the sandy area.

Floristic data from the Great Plain of Hungary (Alföld)
304–316Views:196In this study we report relevant occurrence data of 49 species and hybrids and their habitats from the Great Plain registered in the period between 2011 and 2017. Due to importance for nature conservation, we present additional data of further 13 species. Most of the data are originated from riverine oak-elm-ash forests of South East Hungary (from the region of Gyula, Békéscsaba, Doboz settlements). The most important result of our study is the rediscovery of Gagea minima and Dictamnus albus. Besides, we report new occurrence data for the Great Plain (Alföld), as well as for the flora of the microregions in questions (e.g. Draba muralis, Nicandra physalodes, Cystopteris fragilis) and also present the data of the regionally endangered species (e.g. Inula helenium, Ophioglossum vulgatum). Some rare weed taxa (e.g. Calepina irregularis, Cardamine impatiens), spreading adventive taxa (e.g. Chorispora tenella, Euphorbia maculata, Phytolacca americana, Ph. esculenta, Sicyos angulata) and in surveys rather underrepresented species (e.g. Loranthus europaeus, Arabis hirsuta, Rumex confertus) are reported too.

Contributions to the knowledge of biology and Hungarian distribution range of Orobanche reticulata
95-98Views:415Some new Hungarian occurrences of Orobanche reticulata Wallr. are discussed in this paper. On the Bér-hegy hill (Eastern Bakony Mts) the species was observed on a so far unknown host plant (Carduus hamulosus). Although the species usually flowers from May to July in Hungary, the observed individual was in full bloom in October, probably due to the extremely rainy year (2010). Another population of the species, found at Magyaralmás settlement in the foreground of the Vértes Hills, deserves attention because of its size. In early summer of 2020, individuals of O. reticulata appeared in a great quantity (several hundred ones) on a fallow land that was developed from a natural dry grassland having been ploughed in the previous year. In this case the local host plants were Carduus nutans subsp. leiophyllus and Carduus acanthoides. Some further records of the species from the Transdanubian Mts and the regions of Külső-Somogy and Mezőföld present new data in the Hungarian flora mapping program.

The Wildflower of the Year 2016 in Hungary: snake's head fritillary (Fritillaria meleagris)
79–100Views:915In this paper a short review of the nomenclature and etymology, taxonomy, morphology, histology, life cycle, phenology, reproduction, habitat preference, biotic interactions, biologically active compounds, micropropagation, applications possibilities and conservation status of snake's head fritillary (Fritillaria meleagris L.) can be found. Refining of the European distribution area and contributions to the distribution in Hungary are also presented. Primer seed-set, thousand-seed weight, soil charac¬teristic and demographic data are published.

Data to the distribution and nature conservation of Sorbus bakonyensis
229-233Views:1313Sorbus bakonyensis (Jáv.) Jáv. (syn. S. majeri Barabits) is an apomictic species with a very narrow distribution range in the Bakony Mts (Hungary). Its previous occurrence data were published only from Kopasz Mt. (~Kápolna Hill, Csordás valley) above the village Márkó. It was possible to slightly expand the known area of the species to the East and to the West (Kis-Bükk Mt) of Kopasz Mt. with a detailed mapping. Due to the number of known individuals (six mature trees and a variable number of seedlings) and its small distribution range (~2 km2) the species is critically endangered. Regarding its small population, the high number of big game (wild boar, red deer) and the more and more frequent drought periods are significant risk factors. In situ preservation of the species is still a realistic goal, but ex situ propagation in tree nurseries and reintroduction to the suitable habitats of the mapped area (clearings, forest edges) are also justified.

Notes to the vascular flora of Sopron Mountains and its foreground
187–194Views:310Records of 26 vascular plant species from the territory of Sopron Mountains (16 species) and Sopron Basin (11 species) are presented. Our field works (between 2014 and 2020) focused on some localities at the eastern and southern parts of the region. Tetragonolobus maritimus is new for the Sopron Mts, whereas Ajuga chamaepithys and Lycopsis arvensis are new for the Hungarian part of the hills. Some protected plants like Agrostemma githago, Gentianopsis ciliata and Sesleria uliginosa were rediscovered in the region. Comments about all species and their local chorology are added. A remarkable degradation process of bogs around Harka village, caused mainly by insufficient water supply of meadows, was observed. The spread of occurrences of several naturalized weed such as Aegilops cylindrica, Galium parisiense, Geranium rotundifolium, Kochia scoparia, Lepidium virginicum, Oenothera salicifolia, Sagina apetala subsp. apetala and Verbascum lychnitis was noticed. The most surprising observations refer to Galium parisiense; the spread of the species by transport had no precedent in Hungary before.

The Wildflower of the Year 2014 in Hungary: Siberian flag (Iris sibirica L.)
268-285Views:173In this paper a review of the nomenclature, etymology, taxonomy, morphology, histology, life cycle, phenology, reproduction, habitat preference, biotic interactions, biologically active compounds, micropropagation, application possibilities and conservation status of Siberian flag (Iris sibirica L.) can be found. Leaf traits, phenological data, seed-set, thousand-seed weight, germination, growth rate and soil characteristic data are published based on original observations:
- Leaf area is between 25,3 and 52,9 cm2, its dry mass is 232 and 272 mg/g, specific leaf area is 14,5 and 15,0 m2/kg; based on measurement of 5–5 leaves of sibirica, collected from Tapolca and Létavértes (Hungary) in May of 2014.
- Based on herbarium dataset, blooming of sibirica begins at the end of April and lasts to early-July, contrary to the literature data (May–June).
- Capsules contain (0–)58–76(–121) fertile seeds. (20–)60–80(–90)% of ovules develops to (seemingly) viable seeds, meanwhile the other ovules remain as aborted ones or develop to infertile seeds (probably because of absence of resources); based on fruits collected from Regéc (Hungary) in 2014 and 2015.
- Thousand-seed weight of sibirica is 8,8298–11,2914 g (based on 3×100–100 seeds collected from Regéc and Tapolca in 2014 and 2015), which is lower value than the literature data.
- In our germination test (50–50 seeds sowed to wet soil, after different treatments) 14% of scarified seeds, 6% of scalded seeds, 4–4% of imbibed and control seeds, 0–0% of cooled and refrigerated seeds are germinated. Scarified seeds germinated in the 8–26th days, imbibed seeds 15–19th days, control seeds 16–20th days, scalded seeds 20–23th days after sowing. It seems that scarification stimulates, meanwhile temperature-treatments inhibit the germination. Until 18 weeks the seedlings grow to 30 cm (in mean) and develop 5–7 leaves (in mean). After the 14th week, the first and littlemost lateral leaves are necrosed.
- Analyses of soil samples collected from 17 locations of sibirica in Hungary, suggest that the species prefers highly acidic to slightly alcalic, lime-free to highly calcareous soils with generally high amount of humus and clay, different amount of phosphorus, potassium and nitrogen and low concentration of salt.

Some floristic data from surroundings of Kötcse (South Transdanubia, West Outer Somogy)
74-80Views:113There are very few published and documented floristic data from the hills of the SW region of Hungary called 'Outer Somogy'. This paper present the occurrence data of 31 vascular plant species from the western part of this region. Among them 14 taxa are legally protected and further 17 taxa are sporadically occurring. The records were collected within the administrative area of villages Karád, Kereki, Kötcse, Nagycsepely, Szólád (Nezde) and Teleki. Most data were recorded in 2014. This is the first report on the occurrence of 1) Neotinea ustulata subsp. aestivalis in South Transdanubia, and 2) Epipactis microphylla and E. tallosii in Outer Somogy. Data provided on the occurrence of Cirsium boujartii on the northwestern border of the distribution area of this insufficiently known species.

An identification key for Hungarian botanists portrayed in Album Kleinianum
117-132Views:118In 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.

Asplenium ceterach s.str. and Polystichum aculeatum on the ruins of the copy of Eger Castle, in the Pilis Mts
93-94Views:229In the company of a single individual of Asplenium trichomanes L., several individuals of Asplenium ruta-muraria (L.) Hoffm. and a single individual of Dryopteris filix-mas (L.) Schott, 15 individuals of Asplenium ceterach L. (s.str.), and a single individual of Polystichum aculeatum (L.) Roth were found on a NW facing mortared sandstone wall of the copy of Eger Castle in the Pilis Mts. Asplenium ceterach s.str. is new to the flora of the Pilis Mts. The source population of this stand is probably located in the Buda Mts (Remete gorge) and this fern may have appeared on this wall 5–10 years ago at the latest.

Rubus armeniacus Focke, an unnoticed invader in the Hungarian flora
220-228Views:104The 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.

Rare vascular plants and fungi of Zalaegerszeg-Botfa (W Hungary)
95-103Views:194The present study reports the occurrence data of 3 macrofungi and 47 vascular plant taxa, collected in Zalaegerszeg-Botfa between 2006 and 2017. These new data provide valuable additional information to the distribution map of the studied species. The spatial and abundance information of both protected and non-protected species can contribute to the future biodiversity monitoring activities in order to asses and mitigate the human impact upon natural plant communities and semi-natural habitats.

On the former occurrence of Calla palustris in Hungary
200-210Views:1712The origin of a more than 150 years old herbarium specimen of Calla palustris L. stored in JPU is reconsidered in this study. According to the information on its label, the specimen was collected in 1856 at Lake Velence, close to Székesfehérvár city (central Hungary). Some Hungarian botanists are skeptical about the authenticity of this record. Based on the current occurrences of some remarkable swamp species (e.g. Carex pseudocyperus, Liparis loeselii, Sphagnum spp.) and habitat types (e.g. willow carrs and swamp forests) at the lake, as well as the habitat preference of bog arum, there is no reason to question the former occurrence of the species here or even in other Hungarian localities. The content and accuracy of the examined voucher meet the expectations of floristic data. However, in the absence of recent data the species can be considered extinct from Hungary.

The clammy goosefoot (Chenopodium pumilio R.BR.) in Zugló (Budapest) and new data on the distribution of invasive species in NE Hungary
221-226Views:126The paper summarise occurrences of some rare invasive weeds of Hungary. We found currently second population at the Australian origin Chenopodium pumilio in Budapest (Zugló) in September 2016. Further, 27 occurrence data of 8 other species (Amaranthus deflexus, Echium maculatum, Lepidium densiflorum, Oxybaphus nyctagineus, Panicum dichotomiflorum, Portulaca grandiflora, Sarothamnus scoparius, Tragus racemosus) is also reported in the persent paper from the ‘Északi-középhegyég’ area (Northeast-Hungary), and some data from beside the Hungarian–Slovakian border, especially settlements, strongly disturbed places (especially road curbs, pavement cracks, train stations), indicating the Central European flora mapping system quadrate number. Voucher specimens were deposited in herbarium of Hungarian Natural History Museum, Budapest (BP).

New occurrence of Caldesia parnassifolia (L.) Parl. in Hungary
50-55Views:87Caldesia parnassifolia is a critically endangered and strictly protected species in Hungary. It was known only from one locality of occurrence so far, where it was last reported in 2003. Its new occurrence was discovered in Somogy county, in 2010. It appeared in an artificial pond created in the place of an originally swampy depression. Based on this newly discovered occurrence we can assume that other potential populations might still exist in South-Transdanubium, which could be rediscovered if similar conservation measures occur.

Contributions to the flora of kurgans in the Middle Tisza region
94–105Views:533Kurgans 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 barrelieri, Centaurea solstitialis, Ranunculus illyricus and Phlomis tuberosa) or regionally rare (e.g. Aegilops cylindrica, Astragalus austriacus, Glaucium 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.
