    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).

    The paper introduces the “Zoltán Siroki Herbarium” (on the basis of the MS Excel spreadsheet database of the collection) which is a separate section within the Herbarium of Debrecen University (DE). The Zoltán Siroki Herbarium consists of ca. 20 000 specimens from almost all European countries, but mainly from the historical territory of Hungary. Although ca. 400 botanists contributed to this collection, most of the specimens were collected by Zoltán Siroki in Hajdú-Bihar, Pest and Borsod-Abaúj-Zemplén counties. The most rapid growth of the Herbarium took place in the middle of the last century (from the 1940s to 1960s), but Siroki remained an active collector until the 1980s. Some specimens from the Herbarium of former Royal Seed Testing Station (Budapest) was also incorporated in this collection; they represent gatherings from the last decades of  the 19th century and first decades of the 20th century. Data on the most significant part of the collection, representing native plants collected in the present-day Hungary, are summarized in Electronic Appendix 1. (incl. taxon name, settlement, collecting year, collector, file name of documentary photograph).

  • The occurrence of Pterygoneurum squamosum Segarra et Kürschner on a reclaimed waste storage near town Győr (NW Hungary)

    In the article a new locality, range map and habitat description of Pterygoneurum squamosum is provided from Hungary. Differently from up to the present known localities, the moss was found on anthropogenic habitat, eroded and clayey soil surface. Considering the climatic and soil conditions there, probably this rare Mediterranean species has wider ecological tolerance, so we come across it on further man-made habitats, as well as on loess walls.

  • Campylopus flexuosus (Hedw.) Brid. in the Western Mecsek Mts. (South Transdanubia, Hungary)

    During a field survey in 2014, new localities of Campylopus flexuosus, were found in humid acidophilous oak and beech forests in the Western part of the Mecsek Mts. As a new element of the Hungarian bryoflora, C. flexuosus was discovered in 2013 in the Bakony Mts by Peter Erzberger and Csaba Németh. The localities of the sometimes extensive stands are enumerated, the size of the populations is estimated and the associated bryophyte and higher plant species are listed. Some morphological differences between C. flexuosus and the similar moss Dicranum flagellare are described and illustrated. Some interesting results of a revision of D. flagellare specimens in BP are compared with the actual distribution of C. flexuosus and lead to the conclusion that this species can be treated as a potentially expansive moss in humid acidophilous forests of the Mecsek Mts.

  • Asparagus verticillatus L. in Hungary

    Climbing asparagus (Asparagus verticillatus L.) a new adventive species to the Hungarian flora was recently discovered in the city of Pécs (South Hungary) in 2011–2012. Taxonomy, morphological description and current localities of the species are presented in this paper. A. verticillatus is a mediterranean-submediterranean species native in Balkan Peninsula, Eastern Europe, Western- and Middle Asia. The species is a popular ornamental plant in Hungary, but no data was available about its escape or naturalisation in the country so far. Herbarium specimens from Hungary were collected so far mostly from botanical and private gardens; only one specimen was collected in a dry grassland along a roadside in the city, respectively. The newly discovered small populations are located mostly in secondary dry grasslands, at the edges of vineyards and private gardens on the southern slopes of the Mecsek Mts and only one specimen was found far from the residential area in natural vegetation. Because climbing asparagus is a frequently planted ornamental plant in several locations of Pécs, further escape, naturalisation and persistence of the species is possible in the future.

    The subgenus Ceratochloa is a taxonomically difficult small group of the genus Bromus. The species of this subgenus are mostly native to America, and are often introduced to other continents. Two species of them, namely B. catharticus and B. carinatus have been reported from Hungary so far. Bromus catharticus was first found in Győr city in the 1910s, much later (in the 2000s) in Környe and Kálmánháza villages. The Hungarian records of B. carinatus come from Keszthely and Sopron cities. We have recently found two new occurrences of B. catharticus in the city of Pécs, South Hungary.

    On 14 August 2012 a small population of Reseda inodora was found in Hegyes-halom kurgan within the administrative boundaries of the town of Mindszent (Csongrád County, CEU: 9487.3). The approximately 50–100-stem-large population of the species lived on the edge of the kurgan, on the sparsely vegetated, weedy fieldmargin. On 19 July 2014 this species has turned up again in this area. In this case it was the biggest amount with some hundred stems and was located on the edge of the mound, which is in the verge of the neighbouring corn field. The Reseda inodora is a new recent protected vascular plant species within the operation area of the Körös–Maros National Park. We propose this species to be included in the regional red list in the category of „CR” (Critically endangered). Other rare weed or pioneer species (Caucalis platycarpos subsp. muricata and subsp. platycarposErodium ciconiumLappula squarrosaMelica transsilvanicaPapaver hybridum) have already been found in Hegyes-halom kurgan in the last few years. The results show the importance of kurgans not only in the conservation of natural steppe, loess wall vegetation and steppe shrub species, but in the survival of some endangered weed species as well (e.g. some rare archaeophytes).

    Related 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.

    There are very few published and documented floristic data from the hills of the SW region of Hungary called 'Outer Somogy'. This paper present the occurrence data of 31 vascular plant species from the western part of this region. Among them 14 taxa are legally protected and further 17 taxa are sporadically occurring. The records were collected within the administrative area of villages Karád, Kereki, Kötcse, Nagycsepely, Szólád (Nezde) and Teleki.  Most data were recorded in 2014. This is the first report on the occurrence of 1) Neotinea ustulata subsp. aestivalis in South Transdanubia, and 2) Epipactis microphylla and E. tallosii in Outer Somogy. Data provided on the occurrence of Cirsium boujartii on the northwestern border of the distribution area of this insufficiently known species.

  • Ceratocephala testiculata (Crantz) Roth and further data to the flora of the foothills of Bükk Mts.('Bükkalja', NE Hungary)

    This paper reports new floristic data of 367 taxa (365 species and two hybrids) from the foothill region of Bükk Mts. ('Bükkalja', NE-Hungary) based on 5470 field collected data records. The data was collected between 1997–2014 and supplemented with herbaria (altogether 344 herbaria sheets). Data evaluation was based on the comprehensive Bükk Flora of András Vojtkó and further papers. Altogether 45 species were registered as previously unreported from the area, whereas three species had old data (Acer negundoElaeagnus angustifoliaXanthium strumarium). Out of the newly registered species six native species inhabits natural habitats (Carex flaccaCeratocephala testiculataGlycerrhiza echinata, Gypsophila paniculataKochia lanifloraMarrubium vulgare), whereas five species represents the weed flora (Anthemis ruthenicaChenopodium ficifoliumEragrostis pilosaSenecio vernalisXanthium strumarium). The majority of the newly observed species are adventives. Five species were also regarded as recent introduction regionally, although they are native in the country (mostly lowland species: Crypsis alopecuroidesLimonium gmelini subsp. hungaricumSalsola kaliScirpoides holoschoenusTrifolium angulatum). Typical threats observed are landscape and habitat degradation by invasive alien species out of which 11 are newly added. Mass occurrences were detected for the following invasive alien species: Bidens frondosaImpatiens glanduliferaPhytolacca esculentaXanthium italicum. 43 species are also registered, which did not have recently published data from the area. These species include more native elements representing different habitat preferences (dry grasslands, wet meadows, forest and weeds). In case of 65 species the unravelled new occurrences increased significantly, thus contributed to the clarification of their distribution pattern. It was found that the floristic data accumulated on a decade-scale are not sufficient for the analysis of floristic trends, but could serve as a good basis for surveying floristic gradients between the mountainous and lowland areas.

    Fragments of the natural grassland vegetation are often preserved only in those areas which are inadequate for arable farming. In many cases kurgans hold the last remnants of dry grasslands in lowland areas, like the Great Hungarian Plain. They also have an essential role in preserving cultural and landscape values. Moreover, they harbour several rare plant and animal species. Our aim was to explore the vegetation of the Mondró-halom kurgan (Hencida, East Hungary). Altogether we found 74 vascular plant species in the loess grassland of the kurgan. Several rare species of the Bihari-sík region, such as Inula germanicaRanunculus illyricus and Rosa gallica were also detected. The steep slopes of the kurgan with various micro-sites and exposures supported a species-rich vegetation. Instead of its small area it harboured several forest steppic species and several steppic flora elements (Continental, Pontic-Mediterranean, Pontic, Pontic-Pannonic and Turanian).

  • Rediscovery of Crepis mollis (Jacq.) Asch. subsp. hieracioides (Waldst. & Kit.) Domin in Hungary

    Crepis hieracioides (= C. mollis subsp. hieracioides) was described from the Bakony Mts. (Western Hungary) by Pál Kitaibel more than 200 years ago. His record has been the single one of this taxon from the territory of present-day Hungary thus far. In the second half of the 20th century this taxon was either reported as ‘extinct’ or was plainly ignored in the Hungarian literature. This paper reports about the recent rediscovery of C. mollis subsp. hieracioides in the Bakony Mts., specifically in the ‘Bakonyalja’ region (Devecser: Széki-erdő). The habitat is characterised, and the regional phytogeographical significance of this taxon is emphasised.

    Hybridization is very rare between the species of Himatoglossum genus, despite the fact that it is common in other orchid genera. The reasons for this can be the lack of overlapping distribution areas or the different flowering period of the species. In the paper distribution and flowering data of Himantoglossum species are presented from herbarium sheets or references (sources paper-based or internet). We collected 1001 precisely dated flowering records of 12 species. In case of 6 species (H. adriaticum, H. caprinum, H. comperianum, H. hircinum, H. jankae, H. robertianum) we had sufficient records to calculate the average flowering day and blooming length. According to the collected data the distribution of the species are overlapping except for H. formosum, H. galilaeum and H. metlesicsianum. Studying 55 species pairs, insignificant differences in blooming time were only at 21 species pairs, among them only 5 (H. comperianum - H. caprinumH. montis-tauri - H. comperianum, H. hircinum - H. adriaticumH. montis-tauri - H. caprinum és H. jankae - H. calcaratum) have overlapping distribution area. Data on hybridization could be found only at three species pairs among them. From the results we can conclude that in the case of Himantoglossum genus the rarity of hybridization is mostly due to the phenological isolation.
