Contributions to the Atlas Florae Hungariae VI.
87-102Views:620The 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.

Chorological notes on the vascular flora of Hungary
85-119Views:594The paper presents 1593 current chorological data of 584 taxa (species, subspecies, varietas, hybrids) from Hungary, collected during the last few years. All of these connected also to a total of 184 CEU quadrats. Among the species characteristic to the natural habitats, we highlighted the records of several species protected in Hungary (Adoxa moschatelina, Althaea cannabina, Cardamine parviflora, Centaurium pulchellum, Gagea pusilla, Orobanche reticulata, Potentilla patula, Rosa zagrabiensis, Spergula pentandra, Trifolium diffusum, Valerianella dentata, V. rimosa, Veronica officinalis, Viola collina and V. pumila). In the Northern part of Hungary, we observed the establishment of Cerastium dubium and Ranunculus pedatus at several places along roadsides, which species have been known from the surrounding saline areas for a long time, but their appearance at roadsides is relatively new phenomenon. In addition, Aegilops cylindrica, Crypsis schoenoides, and Fumaria vaillantii subsp. vaillantii were found in one location – each species on roadsides. Along the railway tracks, we found disturbance-tolerant pioneers of rocky grasslands, open sandy and loess grasslands, e.g. many population of the native Androsace elongata, Anthemis ruthenica, Centaurea arenaria, Draba nemorosa, Erodium ciconium, Medicago monspeliaca, Microrrhinum minus, Saxifraga tridactylites and Vulpia myuros were found, as well as numerous ruderalia and the archaeophyt such as Aegilops cylindrica. In addition to the more common species from the urban flora, we present some new data on the occurrence of the rarer Amaranthus blitum subsp. emarginatus, Chenopodium glaucum, Ch. murale, Ch. opulifolium, Ch. vulvaria and Euphorbia peplus. We have also listed some of the rarer field weeds and species that can establish in younger and older old-fields. Bromus secalinus has been found in several places in the northeastern part of Hungary. We also observed Calepina irregularis, Centaurea solstitialis, Centaurium pulchellum, Erysimum cheiranthoides, Filago lutescens, Fumaria officinalis subsp. officinalis, Geranium dissectum, Misopates orontium, Myagrum perfoliatum, Reseda phyteuma, Spergularia salina and Veronica anagalloides populations. Erodium hoefftianum is a member of the natural flora, but is now found only in old-fields. We found some pasture weeds in regions where they are not common (e.g. Bupleurum tenuissimum, Cerastium dubium and Trifolium striatum). The study also presents some species that are data deficient for taxonomic reasons, but not very rare ones (or we don’t know that). This group includes Arabis sagittata, Bolboschoenus glaucus, Bromus commutatus, B. racemosus, B. ramosus, Fumaria vaillantii subsp. schrammii, Ononis spinosiformis subsp. semihircina, Potentilla collina and Viola suavis “white morfotype”. We have drawn attention to the effect of ecological-botanical works on flora-influencing. We found Anthemis ruthenica (species of sandy grasslands) in a mountain meadow, which is probably the result of seeds accidentally introduced by researchers. Finally, the paper provides data on the current distribution of hybrid taxa. A new individual of Betula ×rhombifolia was established in the Mátra Mts. We found some Euphorbia individuals that appeared to be a transitional form between E. esila and E. virgata (E. ×intercedens; Eu. esula subsp. saratoi). We also present some Verbascum and Viola hybrids. Hybrids were determined on a macromorphological basis.

Contributions to the Atlas Florae Hungariae II.
227-252Views:811The 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.

Contributions to the Atlas Florae Hungariae III.
122-146Views:1853The 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.

Taxiphyllum densifolium (Taxiphyllaceae) and other rare bryophytes of the Mecsek valleys (SW Hungary)
3-16Views:416In this paper, we deal with threatened and/or legally protected bryophytes found in the shady, forested valleys of the Mecsek Mountains, which are rare in national and/or local terms. Taxiphyllum densifolium, a rare moss in Europe has stable colonies with sporophytes in two valleys. This study is the first to describe the spore characteristics of this species. The previously considered unique and legally protected Rhynchostegiella teneriffae is nowadays so widespread in the Mecsek that it can no longer be considered a vulnerable species (VU) in Hungary. We present the first population of the legally protected Neckera pennata in Tolna county, and we also report on the recent, unusual occurrence of the data-deficient (DD) Fossombronia wondraczekii. We also list new populations of three other endangered (EN) species, Blindiadelphus recurvatus, Palustriella commutata and Porella arboris-vitae. Several vulnerable (VU) taxa such as Blepharostoma trichophyllum, Porella cordaeana, Sciuro-hypnum flotowianum, Seligeria pusilla, as well as new occurrences of near threatened (NT) mosses such as Microeurhynchium pumilum (with sporophytes), Phaeoceros carolinianus are documented. In addition, the data on Rhynchostegium rotundifolium in Jakab Mountain, which has not been recorded for more than 50 years, is confirmed. The difficulties of differentiating Hygroamblystegium species are briefly discussed.
