Contributions to the Atlas Florae Hungariae XII.
77-84Views:445In 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.

In memoriam Zoltán Siroki (1906–1987)
3-14Views:103Zoltán Siroki (1906–1987) was a Hungarian agronomist and lecturer. His professional activity was connected mainly to Debrecen. Beside his widely known ornithological studies his floristic and fitocoenological data to Matricum, Crisicum and Nyírségense Hungarian regions are also important. Herbarium of Zoltán Siroki, consisting of ca. 20 000 specimens is a remarkable part of the Herbarium of Debrecen University (DE).

Oak-ash-elm forests in the Nyírség
179-220Views:125This paper presents phytosociological analyses of oak-ash-elm forests of Nyírség, NE Hungary. These climatically azonal forests grow in habitats where the soil is under the continual influence of the groundwater table, which maintains rather mesic conditions. They are particularly rich in Fagetalia elements (Actaea spicata, Allium ursinum, Anemone ranunculoides, Asarum europaeum, Athyrium filix-femina, Cardamine bulbifera, Carex pilosa, Cerastium sylvaticum, Chaerophyllum aromaticum, Corydalis cava, Dryopteris filix-mas, Epipactis helleborine agg., Euphorbia amygdaloides, Galeobdolon luteum, Galium odoratum, Hedera helix, Isopyrum thalictroides, Lathraea squamaria, Lathyrus vernus, Lilium martagon, Majanthemum bifolium, Mercurialis perennis, Milium effusum, Polygonatum multiflorum, Pulmonaria officinalis, Ranunculus cassubicus, Salvia glutinosa, Sanicula europaea, Scilla vindobonensis, Stachys sylvatica, Stellaria holostea etc.) typical in the submontane regions of this part of Europe. It is possible that they are remnants of the vegetation dominating the region under the less continental and more moist climate during the Beech phase (2500–800 BC) of the Holocene.
