    Dr. Sándor Polgár was the most outstanding botanist of Győr county (NW Hungary). He provided important results in floristic studies, phytogeography, taxonomy and in the research of alien plants. „Győr megye flórája” („Flora of Győr county”), published in 1941, was one of the most important monography in his period. He is the author of the rare, hybridogenous species Ornithogalum ×degenianum, known only from HungaryHis private herbarium was one of the biggest in Hungary with more than 20,000 specimens. As a teacher he taught geography and nature studies in his home town Győr between 1900 and 1935. Because of his Jewish origin, he was a victim of the holocaust in 1944.

    Zoltán 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 MatricumCrisicum 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).

  • Data to the flora of Southern-Nyírség and its surroundings

    In this paper we provide data on the flora of Monostorpályi, a floristically underrepresented settlement in South-Nyírség and Berettyó–Kálló interfluve, and publish some interesting floristic observations from the Debrecen city area. In our compilation we provide data on 58 plant species. Among the species listed in the enumeration we find taxa from the region not previously reported at all (Lathyrus nissolia, Gagea villosa, Catabrosa aquatica, Potamogeton lucens, P. pusillus). In total, we publish new occurrence data for 16 protected plant species, which are generally typical of the natural habitats of the Nyírség, but are on the decline overall (e.g. Hottonia palustris, Dianthus superbus, Cirsium rivulare, Lychnis coronaria). We also provide data on the distribution of some rare or declining weed species (Anthemis cotula, Myagrum perfoliatum, Agrostemma githago) and confirm the previously known occurrence of some poorly known plant species (Luzula pallidula, Carex hordeistichos). Furthermore, the spread of some alien species (Broussonetia papyrifera, Phyllostachys sp.) is also highlighted.

    János 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.

  • Data to the flora and geobotany of Kisalföld (Lesser Plain) region, NW Hungary

    Lesser Plain (Kisalföld) – divided among three countries (Austria, Hungary and Slovakia) – is the westernmost part of the lowland areas of the Pannonian Basin. Present paper provides a résumé of the authors’ floristic work from the Hungarian part of the area, describing localities, habitats and regional phytogeography of 57 taxa altogether. The localities were listed according to the classification of small geographic regions. The most important results of the study are as follows:

    • We recorded 5 species new to the region (Brachypodium rupestre, Bromus ramosusHypericum dubiumLathyrus sphaericus, Tordylium maximum); all of them can be considered as submontane-montane elements.
    • We reported several species new to a microregion within the Lesser Plain: montane species in the W-SW part of the Plain (Cirsium rivulareDryopteris dilatataEquisetum telmateia), loess-connected species mainly on the Moson Plateau (Agropyron cristatumAllium atroviolaceumEuphorbia salicifoliaViola ambigua); and occurrences of species on sandy soils near the Lake Fertő (Draba nemorosaStipa pennata).
    • We explained the known localities of several salt tolerant species (e.g. Carex divisaCrypsis alopecuroidesJuncus maritimusLimonium gmeliniiSuaeda pannonica) from the Lake Fertő and its surroundings.
    • We assessed the role of the forest management and nature conservational actions in the distribution of some important tree species (Acer tataricumBetula pubescensFraxinus ornusQuercus petraea, Salix pentandra).
    • We discussed the regional nature conservational status of several protected and/or threatened species (e.g. Allium carinatumAllium suaveolensCarex strigosaHottonia palustris, Potamogeton coloratus, Stellaria palustris) in the Lesser Plain.

    The activities of the authors in the surroundings of Győr were supported by monitoring results gained during the Hungarian Little Plain project (LIFE08 NAT/H/000289).

  • The biases of floristic surveys I. Naive planters: “cuckoo” of the Medves (N Hungary)

    The aim of the planned thematic studies is to point out the main biases and/or errors of floristic surveys in Hungary. In this first article of the series we focus on those examples when native species were planted out of their original habitats and/or range by a non-professional naturalist. The sources of information are those letters that were posted by Ferenc Varga to the first author of this article in 2005. The circumstances of the transplantation of 10 phytogeographycally significant species of the investigated area and/or the Pannonicum (Adonis vernalisArum orientaleAsarum europaeumGenista germanicaPhragmites australisPulsatilla grandisP. nigricansSalvia aethiopisViola albaXeranthemum annuum) are detailed in the text and summarised in a table. The correspondence between the first author and Ferenc Varga provides insight how the ambition of a non-professional naturalist can influence the flora of an area. Most of the species were removed from South and transplanted to North, almost 10 km away from their original stands. With the exception of Adonis vernalis and Genista germanica at least one transplantation of the species was successful. In the case of Salvia aethiopis, the naturalized populations came 1.25 km close to Slovakia, where this species is a very rare and endangered (EN) taxon.
