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.

The Wildflower of the Year 2016 in Hungary: snake's head fritillary (Fritillaria meleagris)
79–100Views:841In 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.

Flora of Sztána and Zsobok villages (Transsylvania, Apuseni Mountains, Kalotaszeg)
114-132Views:95The 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.

Land-use history of a habitat of fritillaries (Fritillaria meleagris L.) in W Hungary
25–30Views:104In Hungary, Fritillaria meleagris is known as a species of riparian woodlands however it forms large populations on meadows appeared after woodland clearance too. We monitored one such population on the floodplain of the small river Zala in Western Hungary near Tüskeszentpéter. To explore the history of land use on this site we used the maps of Military Surveys of Hungary, aerial photographs and archive documents (1720–2016). The first written records of the settlement (Tüskeszentpéter) built in a meander of the river Zala are dated to 1301. By 1784, the studied area was covered by wet meadows and only small fragments of forests, as it could be seen on old maps. That time the main livelihood was animal husbandry which required a lot of hay to be stored for winter. These floodplain hay meadows were very productive. Between 1895 and 1930, after the regulation of river Zala flow most of meadows were transferred into arable fields. Small-scale farming almost disappeared by 1960s because of ‘collectivization’. Big hay-cut machinery started to be used and this way of land farming can be seen on the meadows nowadays too. Fritillary populations occur only in areas which have been continuously managed as hay meadows for 300 years. Over six years of observations (2012–2017) the number of annually flowering Fritillaria individuals varied from 630 to 5314. As traditional animal husbandry is no longer economical in Hungary, the maintenance of these historic floodplain meadows depends on different nature conservation supports.
