Occurrence of ferns in secondary habitats of the Great Hungarian Plain
3–14Views:657In this study we report the occurrence data of 14 fern species from the area of the Danube–Tisza Interfluve and the Tiszántúl (Great Hungarian Plain). All data have been collected from secondary habitats, such as buildings and man-made structures, pine plantations and canals. We present new data on seven protected and one alien fern species (Azolla filiculoides). Seven and six species were found together on the brick walls of old buildings near the railway stations in Bácsalmás and Baja, respectively. The new occurrences of Gymnocarpium robertianum, Pteridium aquilinum, Asplenium adiantum-nigrum and Polypodium vulgare have great importance from a floristic point of view. The latter two species were recorded both in pine plantations and on brick walls.

Data on the flora of the burial mounds of the Great Hungarian Plain
31–44Views:176In this paper, we present plant occurrence data from ancient burial mounds, located in the Danube–Tisza Interfluve (Praematricum and Colocense) and in the Trans-Tisza region (Crisicum), Hungary. We report data on 45 vascular plant species and one fungus (Morchella steppicola) from a total of 109 mounds. Of the species presented, 13 taxa are protected in Hungary, some of which are not rare in the study region (e.g. Aster sedifolius, Astragalus asper, Linaria biebersteinii, and Ornithogalum brevistylum). We present new occurrence records of some spreading annual species (e.g. Aegilops cylindrica, Crepis pulchra, and Trifolium diffusum), as well as data on some species that have not been previously reported from mounds (e.g. Agrostemma githago, Chaerophyllum bulbosum, and Dryopteris filix-mas), and we also publish the occurrences of an alien species (Lolium multiflorum) on burial mounds. In terms of plant biogeography, the occurrence of Orobanche reticulata in Kengyel and Oxytropis pilosa in Tömörkény is considered an especially important data.
