On the former occurrence of Calla palustris in Hungary
200-210Views:1674The 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.

Flowering phenology and distribution pattern of Lizard Orchids (Himantoglossum)
157-167Views:82Hybridization 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.

Escaping of Euphorbia myrsinites from cultivation in Eger (E Hungary)
253–256Views:133Euphorbia myrsinites L. (Euphorbiaceae) is a well-known ornamental plant with native distribution around the Mediterranean Basin, the Black Sea, the Caucasus region and Minor Asia. Its escape from cultivation and its naturalization in Western and Central Europe as well as in North America was reported in many cases. In Hungary, the casual escape of E. myrsinites has been documented more than fifty years ago and new observations were recently reported from different regions of the country. Here, I discuss a new record of the species from the town of Eger (E Hungary). The obtained data allow considering E. myrsinites as a locally naturalized species in the flora of Hungary. According to standardized criteria, the species may be able for local invasions too, but further observations are needed to accurately determine its present status in Hungary.

Contributions to the flora of Western-Transdanubia (W Hungary)
213-234Views:105In this paper, we presented the results of our floristic survey in West-Hungarian region. The data were collected between 2005 and 2015 and supportted with herbaria or photo-documentation. This paper reports new floristic data of 98 taxa from West-Hungary with altogether 172 field-collected data records. In the survey we focused on little-known taxa with a phyto-geographic importance. For some taxa we checked the herbarium specimens of Savaria Museum and Natural History Museum of Budapest. During our fieldwork we recorded 8 species new to W-Hungary, including 3 species considered to be native to the region [Oenanthe banatica Heuff., Koeleria pyramidata (Lam.) P. Beauv., Polycnemum majus A. Braun.]. Almost all of the recorded species are regarded as indigenous plants, many of them has nature conservation importance, thus, their monitoring are highly advised. We found new localities of many species which of high importance for plant geography describing their current distribution. Most of the recorded species occur in natural or semi-natural habitats, but some taxa were found in synanthropic habitats and extensive arable lands.

Contributions to the Atlas Florae Hungariae X.
101–106Views:287This paper is the 10th in the series aiming to contribute with new distribution data to the maps published recently in Atlas Florae Hungariae. Distribution data of 686 plant species from 194 flora mapping units are published in this study, but all of them are listed in an electronic appendix. As a result of local surveys, more than 100 new species were found in a single flora mapping unit. Other “linear surveys” along the National Blue Trail revealed 142 new species in 10 flora mapping units in total. Among these, Carex strigosa is one of the most interesting taxa in the Bakony Mts. Previously published and new distribution data of this legally protected sedge species suggests that it is spreading from SW to NE within the Transdanubian Mts. Results from our survey shows that studying synanthropic habitats like frequently used hiking trails might provide a significant amount of new data points at the scale of Hungarian Flora mapping units. Moreover, similar studies might shed some light on the origins and migration routes (e.g. Illyrian and Dacian routes) of “native” species.

Floristic data from the central part of the floristic region ‘Crisicum’ (E Hungary)
317–357Views:227This paper reports new floristic data of 207 taxa. Data collected between 2005 and 2015; originated from the central part of the floristic region ‘Crisicum’ (i.e. the E part of the Great Hungarian Plain), which is a currently poorly studied area of Hungary from a floristic point of view. The paper reports occurrence localities for some rarities such as Asplenium trichomanes, Marsilea quadrifolia, Sisymbrium polymorphum, Viola stagnina, Gentiana pneumonanthe, Elymus elongatus, Montia fontana subsp. chondrosperma, Ranunculus rionii, Ranunculus illyricus, Myagrum perfoliatum, Sedum caespitosum, Vicia biennis, Dorycnium herbaceum, Oenanthe banatica, Peucedanum cervaria, Echium italicum, Digitalis lanata, Valerianella rimosa, Craex buekii, Cephalaria transsylvanica, Cyperus pannonicus.

Contributions to the flora of kurgans in the Middle Tisza region
94–105Views:491Kurgans 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.

The clammy goosefoot (Chenopodium pumilio R.BR.) in Zugló (Budapest) and new data on the distribution of invasive species in NE Hungary
221-226Views:95The 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).
