Contributions to the Atlas Florae Hungariae XII.
77-84Views:422In this work, we report data supplementing the Distribution atlas of vascular plants of Hungary. Altogether 1325 data of 460 vascular plant taxa are reported as contributions to 149 quadrants in the Central European Flora Mapping grid system. The new stands of Phegopteris connectilis (NW foothills of the Vértes Hills), Sternbergia colchiciflora and Corydalis solida (Danube–Tisza Interfluve), Euphorbia angulata and Potentilla alba (Nyírség) are particularly noteworthy. In addition, new stands of numerous rare or scattered species are also listed: Allium paniculatum, A. sphaerocephalon, Asplenium adiantum-nigrum, Botrychium lunaria, Bulbocodium vernum, Clematis recta, Colchicum arenarium, Cyclamen purpurascens, Dianthus barbatus, Dictamnus albus, Doronicum hungaricum, Epipactis atrorubens, E. microphylla, E. tallosii, Equisetum hyemale, Hepatica nobilis, Hesperis sylvestris, Hordelymus europaeus, Iris aphylla subsp. hungarica, I. arenaria, I. sibirica, I. spuria, I. variegata, Jurinea mollis, Lilium martagon, Linaria biebersteinii, Linum flavum, Listera ovata, Lunaria rediviva, Lychnis coronaria, Melica altissima, Menyanthes trifoliata, Monotropa hypopithis, Muscari botryoides, Ophioglossum vulgatum, Orchis militaris, O. morio, O. purpurea, Ornithogalum brevistylum, Ornithogalum sphaerocarpum, Phlomis tuberosa, Primula veris, P. vulgaris, Pseudolysimachion incanum, Pulsatilla flavescens, Pyrola rotundifolia, Scilla vindobonensis, Scrophularia vernalis, Sedum urvillei subsp. hillebrandtii, Spiranthes spiralis, Stipa borysthenica, Stratiotes aloides, Thalictrum aquilegiifolium, Trollius europaeus, Veratrum album, Vinca herbacea, Vitis sylvestris, Wolffia arrhiza etc.

White willow riparian forests along the upper Tisza River, Hungary
78–100Views:93Forests of the Tisza floodplain in the northwestern part of Hungary include white willow riparian forests (Leucojo aestivi-Salicetum albae) that are phytosociologically little studied. This study summarizes the characteristics of this community based on 25 phytosociological relevés. These forests grow mostly on mud and raw alluvial soil in the low-lying parts of the lower terraces of the floodplain. They are easily separated by their species composition and underdeveloped shrub layer from white poplar gallery forests (Senecioni sarracenici-Populetum albae)., which grow on higher lying ground with rather light sandy soil and typically possess a pronounced shrub layer. The understory of their stands may often host plants that are rare or completely absent in other parts of the country, such as Cardamine amara, Cardamine flexuosa, Cardaminopsis arenosa, Carex pseudocyperus, Carex remota, Chrysosplenium alternifolium, Leucanthemella serotina, Leucojum aestivum, Oenanthe banatica, Scrophularia scopolii, Telekia speciosa, Vitis sylvestris. This community is classified in the „Salicenion albae-fragilis Kevey 2008” suballiance.

White poplar riparian forests on the Csepel-sziget, Middle-Hungary (Senecioni sarracenici-Populetum albae Kevey in Borhidi & Kevey 1996)
57–78Views:171In this paper the white poplar riparian forests (Senecioni sarracenici-Populetum albae) growing on the Csepel-sziget and its vicinity are described and characterized based on 25 phytosociological relevés. These communities grow on loose fluvial sand and raw alluvial soils on the elevated parts of the lower river floodplain. They can readily be distinguished from willow gallery forests (Leucojo aestivi-Salicetum albae) which have no shrub layers and grow in habitats 1–1.5 m below the level of poplar forests on rather heavy and muddy soils. They differ also from the oak-ash-elm forests (Scillo vindobonensis-Ulmetum) growing in the upper floodplain. Certain – partly submontane – plants that are rare or completely absent in other parts of the Great Hungarian Plains may also occur in them, such as Anemone ranunculoides, Carex remota, Clematis recta, Crataegus × degenii, Crataegus nigra, Epipactis helleborine, Equisetum hyemale, Galanthus nivalis, Lathraea squamaria, Leucojum aestivum, Paris quadrifolia, Scilla vindobonensis, Vitis sylvestris. This association is classified in the sub-alliance Populenion nigro-albae Kevey 2008 in the syntaxonomical system.
