The Wildflower of the Year 2016 in Hungary: snake's head fritillary (Fritillaria meleagris)
79–100Views:841In this paper a short review of the nomenclature and etymology, taxonomy, morphology, histology, life cycle, phenology, reproduction, habitat preference, biotic interactions, biologically active compounds, micropropagation, applications possibilities and conservation status of snake's head fritillary (Fritillaria meleagris L.) can be found. Refining of the European distribution area and contributions to the distribution in Hungary are also presented. Primer seed-set, thousand-seed weight, soil charac¬teristic and demographic data are published.

New data on the Hungarian adventive flora: Acer opalus Mill. subsp. obtusatum (Waldst. et Kit. ex Willd.) Gams 1925 in Hungary
229-238Views:58Acer opalus Miller 1768 because of its complex taxonomic status can be interpreted as a collective species which contains several species and subspecies depending on different interpretations. An important adventive occurrence from this collective species was found in a forest that belongs to the Tétényi plateau (Budapest, 11th district) in July of 2009. It is proved to be Acer opalus Mill. subsp. obtusatum (Waldst. et Kit. ex Wild.) Gams. The natural range of the subspecies covers the eastern side of the central Mediterranean Sea region and western Balkan Peninsula. It is a submediterranean-mediterranean, thermophile, shade-tolerant taxon but often appears together lightdemanding species too. In its native range it occurs in beech, pine, sessile oak forests and in different types of dry oak forests as admixed tree species. The subspecies was found in a turkey oak – sessile oak community in Hungary. Several old, seed growing individuals live on the spot which have had continuous seed production. Therefore from the old trees to the young seedlings different age categories are represented.

Notes to the vascular flora of Sopron Mountains and its foreground
187–194Views:298Records of 26 vascular plant species from the territory of Sopron Mountains (16 species) and Sopron Basin (11 species) are presented. Our field works (between 2014 and 2020) focused on some localities at the eastern and southern parts of the region. Tetragonolobus maritimus is new for the Sopron Mts, whereas Ajuga chamaepithys and Lycopsis arvensis are new for the Hungarian part of the hills. Some protected plants like Agrostemma githago, Gentianopsis ciliata and Sesleria uliginosa were rediscovered in the region. Comments about all species and their local chorology are added. A remarkable degradation process of bogs around Harka village, caused mainly by insufficient water supply of meadows, was observed. The spread of occurrences of several naturalized weed such as Aegilops cylindrica, Galium parisiense, Geranium rotundifolium, Kochia scoparia, Lepidium virginicum, Oenothera salicifolia, Sagina apetala subsp. apetala and Verbascum lychnitis was noticed. The most surprising observations refer to Galium parisiense; the spread of the species by transport had no precedent in Hungary before.

In memoriam Zoltán Siroki (1906–1987)
3-14Views:104Zoltán 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).

Forests of the sand-hill region of the Danube–Tisza Interfluve (Convallario-Carpinetum Kevey 2008)
49–76Views:196The heavily fragmented and isolated pedunculate oak-hornbeam forests are remnants of the natural vegetation of the sand dune area of the Danube–Tisza Interfluve, where they are found mostly in interdunal depressions. To determine their main phytosociological characteristics, we collected and analyzed data from 25 stands. The results show that these forests are the most similar in species composition to the oak-hornbeam forests (Convallario-Carpinetum Kevey 2008) described from the Nyírség.
