A first record of Barbarea stricta in northern Croatia, as well as single records of Lindernia procumbens in Transcarpathian Ukraine and Limonium hungaricum in Poland was found. In Hungary, 4 adventive species, Diospyros lotus, Sal...

The cherry plum (Prunus cerasifera Ehrh) is an allochthonous species in Slovakia, characterized by abundant flowering and very good fruit set. It primarily grows along roads and in agricultural biocorridors, where it often replaces autochthonous species of the genus Prunus. It is also used as a rootstock and pollen donor for some species of the gen...

In Slovakia, seven species of flax specialists has been identified: Agrostemma linicola, Camelina alyssum, Cuscuta epilinum, Lolium remotum, Silene cretica, S. linicola, and Spergula maxima. Six of them were reliably documented while occurrence of S. linicola is only hypothetical taking into account the occurrence in some surrounding countries in t...

Distribution of Lolium remotum in Slovakia, a typical linicolous weed, is presented in this paper. The species was recorded in 30 quadrants of the Central European mapping grid; the most of localities were found in the Carpathians which is related to the areas of flax cultivation for the linen industry. While in the 19th century it was relatively c...

A new site of the rare species Polygonum graminifolium (Polygonaceae) was found on the gravel bank of the Dunaj River south of the village of Chľaba (the Burda Hills) in July 2023. The species was growing in species-poor vegetation close to stands of the Bidentetea tripartiti class. The locality represents only fourth record of P. graminifolium in...

On a daily basis, a wide range of materials including inorganic nanoparticles (NPs) inadvertently find their way into the environment. Meanwhile, intentionally used NPs, such as the new generation of nanofertilizers (NFs) are designed to enhance agronomic production. However, their physicochemical properties and not-so-well understood effects raise...

In Slovakia, new localities of Lathyrus hirsutus and seven alien Euphorbia maculata...

The archaeobotanical identification of Vitis pips, which is often based only on visual assessment of the finds or on morphometric methods, is problematic. The problem of distinguishing wild from domesticated strains arises especially in the differentiation of early cultivars. Correct identification often fails even when mathematical methods based o...

Monitoring the occurrence of new alien species among native flora is the first prerequisite for preventing their later invasive spread. During the last decade, we recorded data regarding 25 alien taxa new to Slovakia including 21 casual and 4 locally naturalised species, with ornamental plants predominating significantly. The locally naturalised sp...

The presented 10 th part of the series includes fifteen new chorological records, one from Czechia, two from Hungary, three from Poland, five from Slovakia and four from the Ukrainian Carpathians.

Analyses were performed on the basis of 20 own, unpublished as well as published phytosociological relevés and Borhidi’s ecological indication values. The r...

Ranunculus pedatus is a Eurasian species with a northern distribution edge in southern Slovakia. In the nineties of the 20 th century, it was assumed that the species probably occurs only near Štúrovo. Occurrence in the Hron and Ipeľ basins and several localities in the Podunajská nížina lowland between Komárno and Štúrovo was considered historical...

Here, we present a brief introduction to sixteen full-text research articles of the Special Issue “Progress in Slovak Botany: a successful path to modern research on flora and vegetation” which are more-less a reflection of the current state of the study of botany in Slovakia. The papers bring results of classification and syntaxonomical revision o...

The aim of the work was to collect all floristic data of this weed species, to present its current and historical distribution, and to characterize its typical habitats in Slovakia. As shown in analysis, X...

Various taxonomic concepts of the classification of Cotoneaster species from the area of the Western Carpathians were proposed throughout the years, based on several methodological approaches. In this paper we try to find out, whether it is possible to distinguish these species based on the absolute genome size data. The absolute genome size of 143...

Little is known about the suite of ecological conditions under which characteristic species may continue to develop under the pressure of recent habitat deterioration.

Several methods of tillage are among the practices most destructive to inland saline grasslands, and can result in their complete deterioration. Despite the high frequency of habitat destruction by these means, the recovery of the saline vegetation and regeneration abilities of halophytes are still not sufficiently known. The reaction of inland sal...

Revising herbarium specimens we have confirmed 7 localities of the species, five in Pannonian region (districts of Devínska Kobyla hills and Podunajská nížina lowland) and two of them the adjacent area of the Malé Karpaty Mts. Since the vast majority of sites...

After the Pannonian Sea has dried up, the Pannonian Basin has become a major depression in Central Europe. The continental climate and intensive groundwater evaporation from the upper layers of the soil caused the accumulation of salts and the formation of Solonchak and Solonetz soil. A mosaic of very specific halophytic vegetation has developed on...

2C DNA content and ploidy level variation of Prunus spinosa and closely related taxa together with Prunus domestica L. and Prunus insititia L. was studied in Slovakia. The aim of the study was to define genome sizes and find differences between closely related taxa within Prunus spinosa sensu lato mentioned in previous works. According to our resul...

Anthropogenic habitats and their surroundings are less attractive for botanists. Therefore we often do not have enough knowledge about their flora. The submitted contribution is aimed at processing the diversity of flora of flowering plants on the mosaic of anthropogenic habitats in the western part of the Komárno cadastre, both in terms of the occ...

Historical and current occurrence of perennial grass Melica altissima was studied in Slovakia during 2011–2017.
