Contributions to the flora of Western-Transdanubia (W Hungary)
213-234Views:146In 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:392This 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:295This 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:552Kurgans 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:143The 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).

Contributions to the algal flora of a recently-formed peat moss bog near Kőszeg (W Hungary)
113–130Views:388The 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.

Bruchia flexuosa (Schwägr.) Müll. Hal. a true peculiarity in the Hungarian bryoflora
193-201Views:141The fifth European occurrence of the moss species Bruchia flexuosa possessing a holarctic distribution range with a North American centre was encountered in Hungary. Outside of the North American continent only two Asian (both from Japan) and four European occurrences from four different countries (Italy, Austria, Slovenia, Croatia) have hitherto been reported. Apart from the recent Japan findings and the Croatian record observed in 1987, all other European records date back to the 19th century. Our paper reports the circumstances of the Hungarian occurrence along with a short descriptions and photographic illustrations of both the species and its habitat.

Flora of Sztána and Zsobok villages (Transsylvania, Apuseni Mountains, Kalotaszeg)
114-132Views:136The 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.

Contributions to the Atlas Florae Hungariae IV.
358-382Views:147The paper lists supplementary data to the recently published Atlas Florae Hungariae, mostly from various parts of Transdanubia and the Great Plain. The list includes 72 plant species with at least one new station not shown on their grid-based range map. Certain data confirm old records, whereas some others correct erroneous distribution data. The actual habitats where the plants occur are characterized by their corresponding ÁNÉR codes.
