Dry oak woods on the Szentendre Island
147-178Views:413The phytosociological characteristics of the oak woods on the Szentendre Island were first studied 70 years ago. We conducted a follow-up study to determine the phytosociological relationships of theses woods and assess their possible changes over time. We found that these woods are most similar in their phytosociological characteristics to the closed pedunculate oak forests occurring in the high floodplain in the Szigetköz area (Melico nutantis-Quercetum roboris) along the Danube. Our results also showed a marked increase in the proportion of natural weeds, introduced species and invasive aliens in the studied woods.

Black poplar riparian forests (Carduo crispi-Populetum nigrae) along the river Drava
215–238Views:362The objective of this study is to analyse the phytosociological characteristics of riverside black poplar forests on the flood plain of the Drava River (southwestern Hungary) by means of 25 relevés. Based on the results of traditional analyses (vegetation structure and attributes of constituent species), their ecological niche and place in plant succession, those streamside forests can be identified with the plant association Carduo crispi-Populetum nigrae described from the Szigetköz region (northwestern Hungary). Stands of this association develop from purple willow scrubs (Rumici crispi-Salicetum purpureae), and are located at an elevation about one and a half meters lower than those of its successor vegetation unit, the white poplar association (Senecioni sarracenici-Populetum albae).

Data on the native vascular plant species of the Pannonian Region I. (1–5)
160–172Views:981This is the first part of a series presenting previously unpublished data of importance for the knowledge of native vascular plants in the Pannonian Region. This paper deals with the families Lycopodiaceae, Brassicaceae, Crassulaceae, Rosaceae and Orchidaceae. We document the occurrence of Lycopodiella inundata from a ski slope on the outskirts of Nagyhuta (Northern-Hungary) as a new species in Hungarian flora. New occurrence data are reported for the roadside spreading Sedum caespitosum and Thlaspi alliaceum. We report on the specimens of Spiraea crenata found in the interior of settlements (gardens, cemeteries) between 2019 and 2024. New occurrences of several orchid species rare in Hungary are reported: Himantoglossum adriaticum from the Mecsek Mts, the Balaton highlands, the Bakony Mts and the Szigetköz regions (Western-Hungary); Ophrys fuciflora from Zala and Veszprém counties (Western-Hungary); Dactylorhiza fuchsii from Mezőföld region; Orchis mascula subsp. signifera from the northern part of the Great Plain (Northeastern-Hungary).
