The herbarium of the Botanical Garden of Eötvös Loránd University (BPU)
55–59Views:172The paper introduces the herbarium of Eötvös Loránd University (BPU), currently stored at the Botanical Garden of the University, according to its state in the year 2013. The BPU herbarium consists of ca. 16 000 specimens the relevant data of which have been organised into an OpenOffice Calc spreadsheet database. The specimens were collected in 16 European countries, mainly in the current territory of Hungary (80%), Romania (12%) and Slovakia (5%). Other countries are represented with very few specimens. The vast majority (ca. 70%) of the Hungarian specimens were collected in Pest, Veszprém, Borsod-Abaúj-Zemplén, Hajdú-Bihar and Szabolcs-Szatmár-Bereg counties. Although the gatherings cover a century and a half period of time, the most rapid growth of the collection took place from the 1930s to the 1960s. The most prolific collectors were Rezső Soó and his followers: Lajos Felföldy, Tibor Simon and Szaniszló Priszter. Felföldy and Simon enriched the collection through more than 60 years. Data on the 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).

Some floristic data from surroundings of Kötcse (South Transdanubia, West Outer Somogy)
74-80Views:75There 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.

The Wildflower of the Year 2014 in Hungary: Siberian flag (Iris sibirica L.)
268-285Views:118In 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.

Floristic data from the northern edge of the floristic region ‘Crisicum’ (NE Hungary) II.: Borsodi-ártér és Sajó–Hernád-sík
169–186Views:344In this paper we provide new floristic data for 126 species and one hybrid from the Borsod Plain and the Sajó–Hernád Interfluve (Borsod-Abaúj-Zemplén county, Northeast Hungary) observed between 2006 and 2019. A significant proportion of the data is related to gravel mining activities in the area. We present new localities for rare or sporadic native taxa in Hungary (e.g. Chenopodium murale, Ch. rubrum, Lycopsis arvensis, Chamaenerion dodonaei, Reseda luteola, Senecio viscosus, Gnaphalium luteoalbum, Cyperus glomeratus) as well as rare or sporadic adventive weeds (e.g. Lepidium densiflorum, L. virginicum). We publish additions to the distribution of several legally protected species (e.g. Pseudolysimachion longifolium, Nymphoides peltata, Epipactis tallosii, Leucanthemella serotina). Presence of some taxa is remarkable regarding to the flora of the whole area of Crisicum (Sherardia arvensis, Thymelaea passerina, Silene conica) or the Great Hungarian Plain (Monotropa hypopitys).

Contributions to the Atlas Florae Hungariae VI.
87-102Views:202The current paper is the sixth one in the series aiming to contribute with new distribution data to the distribution maps published recently in Atlas Florae Hungariae. Current occurrence data of 389 vascular plant taxa from 117 flora mapping quadrates (CEU) are provided. New records are indicated from different regions of Hungary; however, most occurrences are located in the North Hungarian Mts and from the city of Szolnok and Western Hungary. Occurrence data of rare native taxa (including data of Equisetum fluviatile, Galium rivale, Gladiolus imbricatus, Hypericum maculatum, Persicaria bistorta, Potentilla inclinata, Ranunculus lingua, Rhinanthus rumelicus, Trifolium fragiferum subsp. bonannii, Viola pumila), rare or data-deficient alien taxa (e.g. Amaranthus blitum subsp. blitum, Cymbalaria muralis, Elymus elongatus, Euphorbia peplus, Heracleum sosnowskyi, Impatiens balfourii, Lepidium densiflorum, Rhus typhina, Telekia speciosa), as well as frequent but more or less underrepresented taxa (e.g. Carex otrubae, Chenopodium polyspermum, Crepis tectorum, Filipendula vulgaris, Petrorhagia prolifera, Poa palustris) are also enumerated. In case of the most common species we provided the CEU codes only.

Contributions to the Atlas Florae Hungariae I.
101–115Views:189The main aim of the present work is to contribute with new data to the distribution maps published recently in Atlas Florae Hungariae. Occurrence data of 297 vascular plant taxa from 247 flora mapping quarter quadrates (CEU) are presented. This floristic paper is somehow unusual because besides the occurrence data of rare or sporadic taxa (e.g. Armoracia macrocarpa (Waldst. et Kit.) Kit. ex Baumg., Samolus valerandi L., Epipactis voethii Robatsch), frequent, but more or less underrepresented taxa (e.g. Ranunculus ficaria L., Viola kitaibeliana Roem. et Schult., Gagea villosa (M. Bieb.) Duby), as well as alien taxa (e.g. Cymbalaria muralis G. Gaertn., B. Mey. et Scherb., Potentilla indica (Andrews) Focke, Tragus racemosus (L.) All.) are also enumerated, since our intention was to fill the – sometimes evident – gaps in the Atlas. The name initials of the author(s) who actually found the given occurrence are presented in brackets at each record.

Contributions to the Atlas Florae Hungariae II.
227-252Views:257The present article is the second part of the series aiming to contribute with new data to the distribution maps published recently in Atlas Florae Hungariae. Current occurrence data of 612 vascular plant taxa from 283 flora mapping quadrates (CEU) are presented. New records are distributed over the entire Hungary, however, most are localised in the North Hungarian Mts. Occurrence data of rare native taxa (e.g. Antennaria dioica, Bupleurum pachnospermum, Carex rostrata, Ceratocephala testiculata, Cicuta virosa, Cirsium boujartii, Epipactis moravica, Lycopsis arvensis, Parnassia palustris, Pyrus nivalis, Rumex kerneri, Rumex pulcher, Silene nemoralis, Stellaria alsine, Teucrium botrys, Vicia lutea), rare or data-deficient alien taxa (e.g. Nonea lutea, Panicum dichotomiflorum, Silybum marianum) as well as frequent but more or less underrepresented taxa (e.g. Eragrostis minor, Heliotropium europaeum, Saxifraga tridactylites) are also enumerated, since our intention was to fill the gaps in the Atlas. Remarcable contribution on the occupied territory of Ranunculus illyricus and Spergula pentandra in the Nyírség region (E Hungary), and on the Hungarian distribution of expanding alien weed Senecio vernalis are also presented.

The herbarium of Debrecen University (DE) I. The “Rezső Soó Herbarium”
142-155Views:130The 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).

Contributions to the Atlas Florae Hungariae III.
122-146Views:195The current paper is the third one in the series aiming to contribute with new distribution data to the distribution maps published recently in Atlas Florae Hungariae. Current occurrence data of 558 vascular plant taxa from 186 flora mapping quadrates (CEU) are presented. New records are indicated from different regions of Hungary; however, most occurrences are located in the North Hungarian Mts. Occurrence data of rare native taxa (e.g. Marsilea quadrifolia, Salicornia prostrata, Stellaria palustris, Potentilla patula, Althaea cannabina, Lythrum tribracteatum, Ajuga laxmannii, Plantago schwarzenbergiana, Alisma gramineum, Gagea bohemica, G. szovitsii), rare or data-deficient alien taxa (e.g. Chorispora tenella, Thladiantha dubia, Senecio vernalis) as well as frequent but more or less underrepresented taxa (e.g. Scleranthus annuus, Vicia hirsuta, V. lathyroides) are also enumerated. In case of the most common species we provided the CEU codes only.

Flora of Sztána and Zsobok villages (Transsylvania, Apuseni Mountains, Kalotaszeg)
114-132Views:61The botanical and ethnobotanical studies of PÉNTEK & SZABÓ (1985) were repeated after 30 years, during an ethnobiological summer school held in Kalotaszeg region (Romania), in Apuseni Mountains. However, our intensive floristical researches focused only on two villages (Sztána and Zsobok). A list of the observed taxa and their frequency values are presented. Of the 747 taxa 52 are new to the narrow region. 74 species reported formerly from here were not found by us. The disappearance of some taxa (e.g. Crepis praemorsa, Conringia orientalis, Lolium temulentum) are probably due to changes in agricultural land use methods. The spread of a few new invasive species (e.g. Ambrosia artemisiifolia, Galinsoga ciliata, Senecio vernalis) as well as the presence of some floristically interesting species (e.g. Centaurium pulchellum, Carex otrubae, C. serotina, Lathyrus pannonicus subsp. collinus, Leucanthemum irrcutianum, Minuartia viscosa, Peucedanum rochelianum, Quercus pubescens, Trifolium diffusum, T. micranthum) and a notomorpha (Cirsium × tataricum) were also noticed.
