In memoriam Frigyes Ágost Hazslinszky [In Hungarian]
3-7Views:134Mondhatunk-e bármi újdonságot két évszázad távlatában olyasvalakiről, akit kortársai, követői számos alkalommal megemlékezéseikben méltattak? Elfeledett életrajzi dokumentumok vagy a hagyaték feldolgozása nélkül aligha. Hazslinszky Frigyes esetében jelenleg nem állnak rendelkezésünkre az életét és munkásságát új megvilágításba helyező tények, talán mégsem haszontalan feleleveníteni vele kapcsolatos ismereteinket...

Contribution to the distribution of Epipactis species in the Keszthely Mts
8-14Views:115In this paper I present occurrence data of Epipactis species in the Keszthely Mts which were collected during the last four years. Ten species had literary or herbarium data from the area previously, all of them has been confirmed (Epipactis atrorubens, E. helleborine, E. leptochila, E. microphylla, E. moravica, E. muelleri, E. palustris, E. purpurata, E. nordeniorum, E. voethii) and another five species (Epipactis albensis, E. neglecta, E. peitzii, E. pontica, E. tallosii) furthermore a hybrid (Epipactis ×reinekei) were found newly on the area.

Dactylorhiza traunsteineri (Saut. ex Rchb.) Soó: an unexpected record in the Romanian flora
15-24Views:103Dactylorhiza Necker ex Nevski is a complex genus. The taxonomy of these dactylorchids is widely considered to be complicated due to relatively high morphological variability within species and high frequency of hybridization between species. During a floristic survey of the Valea Morii (Morii Valley, Malomvölgy) Nature Reserve in June 2017, a population of Dactylorhiza traunsteineri (Saut. ex. Rchb.) Soó, a species with uncertain presence in the Romanian flora was found. In the Morii Valley, this narrow-leaved marsh-orchid was encountered in fen-patches, in phytocoenoses of the plant association Orchido-Schoenetum nigricantis Oberd. 1957. Due to the cool and wet microclimate of the Morii Valley, many glacial relicts and other plant rarities (e.g. Tofieldia calyculata (L.) Wahlenb., Swertia perennis (L.), Liparis loeselii (L.) Rich., Ophioglossum vulgatum L. Schoenus nigricans L.) had been able to survive on strongly humid places on calcareous soils. This study reports the first occurrence of D. traunsteineri in Romania confirming the presence of a highly debated taxon. We also discuss the morphological features, habitat preference and conservation status of this new species in the Romanian Flora.

Land-use history of a habitat of fritillaries (Fritillaria meleagris L.) in W Hungary
25–30Views:124In Hungary, Fritillaria meleagris is known as a species of riparian woodlands however it forms large populations on meadows appeared after woodland clearance too. We monitored one such population on the floodplain of the small river Zala in Western Hungary near Tüskeszentpéter. To explore the history of land use on this site we used the maps of Military Surveys of Hungary, aerial photographs and archive documents (1720–2016). The first written records of the settlement (Tüskeszentpéter) built in a meander of the river Zala are dated to 1301. By 1784, the studied area was covered by wet meadows and only small fragments of forests, as it could be seen on old maps. That time the main livelihood was animal husbandry which required a lot of hay to be stored for winter. These floodplain hay meadows were very productive. Between 1895 and 1930, after the regulation of river Zala flow most of meadows were transferred into arable fields. Small-scale farming almost disappeared by 1960s because of ‘collectivization’. Big hay-cut machinery started to be used and this way of land farming can be seen on the meadows nowadays too. Fritillary populations occur only in areas which have been continuously managed as hay meadows for 300 years. Over six years of observations (2012–2017) the number of annually flowering Fritillaria individuals varied from 630 to 5314. As traditional animal husbandry is no longer economical in Hungary, the maintenance of these historic floodplain meadows depends on different nature conservation supports.

Floristic data from Lengyel–Hőgyész Natura 2000 site (SW Hungary)
31–38Views:168This paper presents occurrence data of 169 taxa from the Lengyel–Hőgyész Natura 2000 site (HUDD20026) which is on the southern part of Tolna Hills, SW Hungary. Data were collected during three years (2015, 2016, 2017), on different sites annually. The presented data contribute to the distribution dataset of Atlas florae Hungariae. Regionally rare or sporadic species (e.g. Asplenium scolopendrium, Asplenium trichomanes, Polystichum setiferum, Doronicum hungaricum, Paris quadrifolia, Scilla vindobonensis) are enumerated. Presence of Epipactis leptochila subsp. neglecta and Platanthera chlorantha were not registered from this site before. Subspecies of Carex divulsa are also studied on this site – distribution of these infraspecific taxa have not been mapped recently in Hungary.

Contributions to the flora of Baranya and Tolna counties III.
39-50Views:149During 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.

Disappearing botanical and cultural heritage of wooden headboard-graveyards in Eastern-Hungary and Transylvania (Romania)
51-64Views:180Degradation or disappearance of natural habitats are global phenomena nowadays, hence the role of small and secondary (seminatural) habitats like cemeteries in preserving natural values are more and more appreciated. The botanical values and burial customs were examined in a total of 51 graveyards in three different regions of Hungary and Romania (10, 19 and 22 graveyards in the North Hungarian Mountains, the Great Hungarian Plain and Transylvania, respectively). Altogether 25 in Hungary legally protected plant species were found, 1.5 protected species per graveyard on average. As we observed, traditional burials with wooden headboards are rapidly superseded by modern burial customs. Based on our non-representative poll (n=102), 90% of citizens on average are satisfied with current conditions in Hungarian graveyards. A two-thirds majority of respondents would prefer more frequent lawn-mowing in graveyards. 75% of respondents prefer modern tombs to traditional graves. Disappearance of old burial customs characterised by the use of wooden headboards (and the simultaneous change in traditional, habitat-friendly practices in graveyards) means not only a loss of cultural values, but threatens the natural biodiversity of graveyards as well.

Botanical comparison of man-made landforms in the Nagykunság and Nagy-Sárrét regions (E Hungary)
65-76Views:213Loess grasslands are among the most important vegetation types of the Great Hungarian Plain. This paper compares the composition of vegetation situated on three types of man-made landforms (burial mounds, Devil’s dykes and river dikes) which were built in different historical times. I studied the similarities and differences in their vegetation, focusing on the rare species and plant associations. I studied six burial mounds, two Devil’s dykes and four river dikes. All of the studied landforms were covered by loess steppes, loess cliffs or Artemisia salt steppes. Devil’s dykes had the most valuable vegetation and they preserve a very diverse flora in the landscape.

The role of clothing in antropochorous seed dispersal
77-86Views:161Humans play an increasing role in seed dispersal. Through human help, seeds can bridge distances which otherwise would not be possible. The most important human-mediated dispersal types are: the spread on clothing, shoes and vehicles. The effect of these dispersal types can be combined in many cases. During dispersal with clothing, the seeds attach to cloths, but its probability depends on whether the seeds or other parts of the plant have morphological characteristics which make the attachment possible (e.g. hooks, hairs, spikes) and on the adhesion characteristics of the clothing (cotton/nylon, drill/cotton). This way, cloth-dispersal can be considered analogous to epizoochory. In our review, we evaluated the publications about human-mediated seed dispersal on cloths. In total we have found twelve experimental and field studies on the topic. So far, seeds of 449 species have been documented to be able to spread on clothing worldwide, out of the 449 species, 262 occur in Hungary. With future studies, these numbers will be increasing considerably. The average dispersal distance of the seeds was estimated between 150 and 5000 m, but the distance could be significantly increased, if means of transport are used during the dispersion. According to the results, the seeds of weed and invasive plants are dispersed most frequently on clothing (87% of all species, 26% of species occurring in Hungary). These cause serious damage worldwide. We emphasise that people should pay attention to the type of clothing, when they are visiting remote and unique nature reserves. For instance, waterrepellent foot wears could significantly reduce the adhesion of the seeds therefore it can prevent unintended seed dispersal. Further investigations are needed to find solutions to these problems, especially in regions with lack of these studies, such as in Europe, South America, Asia and Africa.

Contributions to the Atlas Florae Hungariae VI.
87-102Views:264The current paper is the sixth one in the series aiming to contribute with new distribution data to the distribution maps published recently in Atlas Florae Hungariae. Current occurrence data of 389 vascular plant taxa from 117 flora mapping quadrates (CEU) are provided. New records are indicated from different regions of Hungary; however, most occurrences are located in the North Hungarian Mts and from the city of Szolnok and Western Hungary. Occurrence data of rare native taxa (including data of Equisetum fluviatile, Galium rivale, Gladiolus imbricatus, Hypericum maculatum, Persicaria bistorta, Potentilla inclinata, Ranunculus lingua, Rhinanthus rumelicus, Trifolium fragiferum subsp. bonannii, Viola pumila), rare or data-deficient alien taxa (e.g. Amaranthus blitum subsp. blitum, Cymbalaria muralis, Elymus elongatus, Euphorbia peplus, Heracleum sosnowskyi, Impatiens balfourii, Lepidium densiflorum, Rhus typhina, Telekia speciosa), as well as frequent but more or less underrepresented taxa (e.g. Carex otrubae, Chenopodium polyspermum, Crepis tectorum, Filipendula vulgaris, Petrorhagia prolifera, Poa palustris) are also enumerated. In case of the most common species we provided the CEU codes only.
