Oak-hornbeam and turkey oak forests growing on sand on the foothills of the Pilis Range (Corydali pumilae-Carpinetum, Fraxino orno-Quercetum cerridis)
79–105Views:169We studied the phytosociological characteristics of hornbeam and turkey oak dominated forests growing on sand at the southwestern foot of the Pilis Mountains. Here we present the results of analyses of 10 relevés of each community. The species composition of the hornbeam forest samples is characterized by a relatively high proportion of Fagetalia species. Notable species in the community are Aconitun vulparia, Berberis vulgaris, Epipactis helleborine agg., Galanthus nivalis, Geranium lucidum, Lilium martagon, Omphalodes scorpioides, Piptatherum virescens, Primula veris, Scilla vindobonensis, Sorbus aria agg., S. domestica, Veratrum nigrum, and Waldsteinia geoides. In the turkey oak forests, species characteristic of the class Quercetea pubescentis-petraeae have the highest proportion. Notable and locally typical species occurring in the community are Anthericum ramosum, Digitalis grandiflora, Iris variegata, Piptatherum virescens, Primula veris, Achillea distans, Dictamnus albus, Galanthus nivalis, Lonicera xylosteum, Scilla vindobonensis, Sorbus domestica, Veratrum nigrum, as well as Lunaria annua and Tilia tomentosa that are possibly introduced here. Based on the results of statistical analyses, the two forest communities are best identified with the associations named Corydali pumilae-Carpinetum and Fraxino orno-Quercetum cerridis, both occurring in the Transdanubian Mountain Range.

Sorbus udvardyana Somlyay & Sennikov in the eastern part of the Balaton Uplands
55-58Views:278Related to distribution of S. aria s.l. × S. torminalis hybrid taxa in the eastern part of the Balaton Uplands just data of „S. balatonica” is in the literature based on collection of Ádám Boros (Kárpáti 1960). In the summer of 2014 the author found and mapped a few (sub)populations of S. aria s.l. × S. torminalis at Lovas (Királykúti-völgy, Atya-hegy, CEU: 8973.4) and Felsőörs (Malom-völgy, Kopasz-tető, CEU: 8973.4) villages. Based on leaf-morphological traits the specimens were identified as S. udvardyana.

Contributions to the flora of Budapest and its surroundings III.
227–237Views:202New or recently confirmed localities of 40 rare taxa (including 7 ferns) are presented from the vicinity of Budapest. Some records are new for the flora of particular regions, specifically: Geranium sibiricum (Buda Mts and Budapest), Polystichum setiferum (Pilis Mts), Onosma pseudarenaria, Sorbus aria s. str. (Visegrad Mts). Of the remaining records, the most significant ones are those of Agrimonia procera, Botrychium lunaria, Epipactis tallosii, Gymnadenia odoratissima and Sorbus ujhelyii.

Data to the distribution and nature conservation of Sorbus bakonyensis
229-233Views:1313Sorbus bakonyensis (Jáv.) Jáv. (syn. S. majeri Barabits) is an apomictic species with a very narrow distribution range in the Bakony Mts (Hungary). Its previous occurrence data were published only from Kopasz Mt. (~Kápolna Hill, Csordás valley) above the village Márkó. It was possible to slightly expand the known area of the species to the East and to the West (Kis-Bükk Mt) of Kopasz Mt. with a detailed mapping. Due to the number of known individuals (six mature trees and a variable number of seedlings) and its small distribution range (~2 km2) the species is critically endangered. Regarding its small population, the high number of big game (wild boar, red deer) and the more and more frequent drought periods are significant risk factors. In situ preservation of the species is still a realistic goal, but ex situ propagation in tree nurseries and reintroduction to the suitable habitats of the mapped area (clearings, forest edges) are also justified.

Contributions to the flora of the Heves–Borsod and Uppony Hills and adjacent territories
173–226Views:152Results of nearly two decades of floristic research in the territory of Heves–Borsod Hills (Tarna-vidék) and the northern foreground of the Bükk Mts are presented in this paper (altogether 4421 records; BÁ: 1665, SJ: 2752). Several old literature records – partly supported by vouchers – are confirmed, e.g. Hypericum elegans and Lappula heteracantha from the Uppony Gorge, as well as Cephalaria transsylvanica, Cypripedium calceolus, Diplotaxis erucoides and Plantago indica from the Heves–Borsod Hills and the northern foreground of the Bükk Mts. Other former literature records (partly from the authors) are revised. These revisions are mainly due to changes in taxonomic concepts of some genera in new keys (Carex, Chamaecytisus, Epipactis, Molinia, Sorbus). Old literature and herbarium records of other significant taxa (Onosma visanii, Scutellaria columnae, Sorbus sp., Utricularia bremii/minor) are revised too. The new occurrence of Ferula sadleriana in the Uppony Gorge is probably the result of intentional seed dispersal. Of the many rare plants listed in our paper some are new for the flora of the region under study: Agrimonia procera, Alchemilla micans, Asplenium adiantum-nigrum, Astragalus austriacus, A. exscapus, Blysmus compressus, Carex appropinquata, C. cespitosa, Catabrosa aquatica, Centarea indurata, Dactylorhiza × aschersoniana, Epipactis voethii, Epipogium aphyllum, Equisetum hyemale, Festuca drymeja, Gagea bohemica, Glyceria nemoralis, Hesperis sylvestris, Myosotis caespitosa, Phegopteris connectilis, Platanthera chlorantha, P. × hybrida, Rosa gizellae, Scilla kladnii, Senecio doria, Solanum villosum, Taraxacum palustre, Triglochin palustre. Two phytocoenological relevés representing the habitats of Myosotis caespitosa and Spiraea media are presented. Currently known local distribution of some montane and forest-steppe elements are shown on maps.

In memoriam János Hulják (1884–1942)
5-10Views:91János Hulják prominent Hungarian botanist was born 130 years ago. He worked as teacher and director in elementary school at Pereces (today it belong to Miskolc). He played key role in the floristic exploration of Northern Hungarian Mountain Range. His huge herbarium collection was destroyed during World War II., only the exchange material was preserved (about few hundred sheets), mainly in BP and DE. Some vascular plant species [Centaurea huljakii J. Wágner, Sorbus huljakii Kárpáti, Galium × huljakii Jávorka and Pilosella auriculoides subsp. huljakii (Zahn) Soják] were named after him.

Turkey oak forests on sand (Fraxino orno-Quercetum cerridis) in Vértesalja (Hunga-ry)
34–57Views:109Here we evaluate the phytosociological characteristics of the turkey oak forests on sand (Fraxino orno-Quercetum cerridis) found at the northern foothills of the Vértes Hills, Hungary. Using the traditional Braun-Blanquet method, 20 vegetation samples were collected and compared with turkey oak forests growing in similar ecological situations in other parts of the country. The traditional and multivariate analyses showed that our samples were quite different from the compared forests, and only the forests in the Bakonyalja and the Pilis Mts showed some similarity with the compared forests. Our samples had the lowest proportion of Quercetea pubescentis-petraeae species among the compared forests, and the highest proportion of specialists (Corydalis pumila, Daphne laureola, Doronicum hungaricum, Lychnis coronaria, Physocaulis nodosus, Primula veris, Scutellaria columnae, Sorbus domestica and Veratrum nigrum). The samples were well separated from the compared forests and formed a distinct group.
