Herbarium database of the vascular collection of Eszterházy Károly College (EGR)
339-348Views:145The paper describes the vascular herbarium of the Eszterházy Károly College (EGR) in Eger (Hungary), according to its condition in 2013. All specimens of the herbarium were documented by digital photographs (ca. 8 000 specimens), and all data from the labels were entered into MS Excel spreadsheet. 54% of the specimens were collected in present-day Hungary, the other half comes mainly from the neighbouring countries, but more distant European countries are represented as well. Hungarian specimens were collected mostly in Heves, Pest, Zala, Vas, Borsod-Abaúj-Zemplén and Veszprém counties. Most of the herbarium sheets originated from the 1860’s and the 1950–60’s. Apart from these periods the collection has hardly developed. The most prolific collectors were Gábor Vida, Márton Vrabélyi, Árpád Károlyi and Tamás Pócs. More than half of the Hungarian flora (61%) is represented in EGR, although some taxa (e.g. Pterydophyta, Gymnospermatophyta) are much underrepresented. The digital photographs and the database are property of the authors and the Department of Botany and Ecology of Eszterházy Károly College. Data of non-cultivated plants collected in the territory of present-day Hungary are summarized in an electronic appendix (http://kitaibelia.unideb.hu/?download&aid=852&volume_id=94&lang=hun – including: catalogue number, taxon name, collector, settlement, date of gathering and file name of the documentary photograph). Further data can be required from the corresponding author or the curator of the herbarium.

Fern (Pteridopsida) flora of South Nyírség (East Hungary)
162–182Views:360The study presents a number of new data on the fern flora of South Nyírség, and reviews all available literature and herbarium fern records from the area. A total of 19 Pteridopsida species were detected in the region. The hart's tongue fern (Asplenium scolopendrium) and the soft shield fern (Polystichum setiferum) were hitherto unknown in the whole Nyírség region (flora district “Nyírségense”). The broad buckler-fern (Dryopteris dilatata), scaly male fern (Dryopteris affinis) and floating fern (Salvinia natans) are new records to the area of South Nyírség. Dryopteris dilatata has been found in a surprisingly great number of localities. Some morphological characters facilitating identification of this species are also discussed. The local pine plantations, fens, carrs and humid deciduous forests are important habitats for ferns. In some localities the co-occurrence of 5-6 fern species were observed. The increasing aridity in the last decade is posing a serious threat to ferns in the area.

Occurrences of Kievan nettle (Urtica kioviensis) in the South Nyírség (East Hungary)
126–131Views:247So far, only one herbarium data and one flora mapping data on Kievan nettle (Urtica kioviensis Rogow.) has been known from the Southern Nyírség. Since 2004, the species has been detected in 14 flora mapping quadrats. Its data were also collected in winter because its habitats are more easily accessible on ice, its overwintering shoots are more noticeable, and they are strikingly morphologically different from the great nettle (Urtica dioica L.). Typical habitats were willow carrs (Calamagrosti-Salicetum cinereae), reeds (Phragmitetum communis), rush-beds (Typhetum latifoliae, Typhetum angustifoliae), tufted sedge communities (Caricetum elatae) and tall sedge meadows (mainly Caricetum acutiformis). The largest stocks live in reservoirs in secondary habitats. A significant part of the stocks is located in the wide valleys of the main watercourses in the area.

Data on the occurrence of sedge species (Carex, Cyperaceae) in and around South Nyírség (East Hungary)
165-198Views:401We 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.

Contributions to the algal flora of a recently-formed peat moss bog near Kőszeg (W Hungary)
113–130Views:367The Alsó-erdő peat bog near Kőszeg has undergone a significant transformation since its first mention in the literature. In addition to the original single patch, a smaller one appeared a few decades later. The process did not stop and a third unit, discussed here, was formed. The succession of its macrovegetation towards the typical peat moss association started slowly but surely, due to balanced water regime and other optimal environmental conditions. The process is more advanced for the algal vegetation, which shows the characteristics of peat bogs already. The high species diversity found makes the habitat highly valuable itself. Although a special, unique algal species has not been found in previous studies, 27 Desmidiales taxa listed as endangered occur sometimes with high density and make the habitat even more valuable. Based on our results, the area deserves special attention both from the habitat conservation and research point of view. At the same time, its further monitoring can provide crucial information for exploring and understanding the succession of similar habitats, and thereby for their more efficient protection.

The herbarium of the Botanical Garden of Eötvös Loránd University (BPU)
55–59Views:207The 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).

Flowering phenology and distribution pattern of Lizard Orchids (Himantoglossum)
157-167Views:103Hybridization is very rare between the species of Himatoglossum genus, despite the fact that it is common in other orchid genera. The reasons for this can be the lack of overlapping distribution areas or the different flowering period of the species. In the paper distribution and flowering data of Himantoglossum species are presented from herbarium sheets or references (sources paper-based or internet). We collected 1001 precisely dated flowering records of 12 species. In case of 6 species (H. adriaticum, H. caprinum, H. comperianum, H. hircinum, H. jankae, H. robertianum) we had sufficient records to calculate the average flowering day and blooming length. According to the collected data the distribution of the species are overlapping except for H. formosum, H. galilaeum and H. metlesicsianum. Studying 55 species pairs, insignificant differences in blooming time were only at 21 species pairs, among them only 5 (H. comperianum - H. caprinum, H. montis-tauri - H. comperianum, H. hircinum - H. adriaticum, H. montis-tauri - H. caprinum és H. jankae - H. calcaratum) have overlapping distribution area. Data on hybridization could be found only at three species pairs among them. From the results we can conclude that in the case of Himantoglossum genus the rarity of hybridization is mostly due to the phenological isolation.
