Mondró-halom kurgan (Hencida, East Hungary), a refugium of loess grassland vegetation
143-149Views:469Fragments 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 germanica, Ranunculus 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).

Contributions to the flora of kurgans in the Middle Tisza region
94–105Views:491Kurgans are ancient burial mounds built by nomadic steppic cultures. Embedded in the heavily transformed landscapes of the Carpathian Basin they often serve as last refuges for rare and endangered plant species. In our paper we publish floristic data collected on 82 kurgans located in the area of the Hortobágy National Park Directorate. Our dataset covers 64 CEU quarter quadrates, and the territory of 45 settlements. We provide data on 39 taxa that are either protected (e.g. Anchusa barrelieri, Centaurea solstitialis, Ranunculus illyricus and Phlomis tuberosa) or regionally rare (e.g. Aegilops cylindrica, Astragalus austriacus, Glaucium corniculatum and Trifolium diffusum). Our records demonstrate that kurgans have a vital role in maintaining the populations of rare and endangered grassland species even in transformed landscapes.

Contributions to the Atlas Florae Hungariae XIII.
85-88Views:57885The present paper is the 13th in a series of papers contributing new floristic data to complement the distribution maps of Atlas Florae Hungariae. We present altogether 1307 new occurrence data to advance our knowledge of the distribution of vascular plants in Hungary. New data are presented for 634 vascular plant species from 256 flora mapping quarter quadrates (CEU). Due to the unevenness of data collection, the data are highly dispersed over the area of Hungary. Most of the presented occurrence data are from the Great Hungarian Plain, the North Hungarian Mountains, and the Little Hungarian Plain regions. The enumeration includes rare native species (e.g., Androsace maxima, Erysimum crepidifolium, Orobanche gracilis, Peucedanum palustre, Pulsatilla zimmermannii, Scopolia carniolica, Vicia biennis), rare or data deficient adventive species (e.g., Euphorbia prostrata, Euphorbia serpens, Lindernia dubia), subspontaneous occurrences of native species (Asplenium scolopendrium, Daphne laureola, Chenopodium opulifolium), species spreading along linear infrastructure (Eleusine indica, Plantago coronopus, Sorghum halepense, Spergularia salina, Tragus racemosus), and also common native species with data deficient distribution maps (Agrostis stolonifera, Bromus benekenii, Bromus japonicus, Carex caryophyllea, Carex divulsa subsp. divulsa, Equisetum ramosissimum, Vulpia myuros).
