About the occurrence of Spiraea media Fr. Schm. on the Balaton Uplands
151-154Views:285The presence of Spiraea media on the Balaton Uplands has high plant geographical importance, but the found location has not been known before its recent rediscovery. The Spiraea media was discovered on the Kopasz Hill (Felsőörs) growing in a closed Quercus cerris oak forest (~Fraxino orni-Quercetum cerridis); which is a rather atypical habitat of the species. The appearance of blooming specimens and the rediscovery of the species is probably due to the cut of the neighbouring forest, which has resulted extra irradiation in the area. The 19th century military maps of the landscape show that the former vegetation of the area was characterised by the mosaics of rocky grassland–scrub–forest or rocky scrub rich patches being suitable for the species.

Contributions to the flora of the Heves–Borsod and Uppony Hills and adjacent territories
173–226Views:147Results 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.

Contributions to the flora of Baranya and Tolna counties III.
39-50Views:128During the last four years (2014–2017) that have passed since my last publication, I have been collecting 25 000 new floristic data for the territory of the Danube–Drava National Park. The most valuable and interesting records of 116 taxa are presented here, e.g. those of the strictly protected Digitalis ferruginea and Paeonia banatica, and the protected species Polystichum lonchitis, Dryopteris affinis, Doronicum orientale, Helleborus dumetorum, Corydalis intermedia, Spiraea media, Veratrum nigrum. New records of not protected but rare species, such as Lycopsis arvensis, Silene dichotoma, Teucrium botrys, Thladiantha dubia, Vicia lutea, Hypochoeris radicata are also enumerated. Some curiosities are mentioned as well, including the sizes of the biggest (and probably the oldest) Crataegus monogyna, Hedera helix, Ruscus hypoglossum and Ruscus aculeatus individuals that were found during my field work.
