Data on the native vascular plant species of the Pannonian Region II. (6–22)
233–252Views:1107In the second part of this article series, which provides data contributing to the knowledge of native plant species of the Pannonian Ecoregion, we address rare species – mostly legally protected in Hungary – belonging to the families Cephaloziaceae, Athyriaceae, Dryopteridaceae, Cystopteridaceae, Thelypteridaceae, Brassicaceae, Rosaceae, Elatinaceae, Apiaceae, Orobanchaceae, Liliaceae, and Orchidaceae. We report the current occurrence of Nowellia curvifolia in the Sub-Pannonian region of Slovenia. We present an exceptionally species-rich habitat for ferns (Athyrium filix-femina, Dryopteris carthusiana, D. dilatata, D. filix-mas, Gymnocarpium dryopteris, Polystichum aculeatum) from the ‘Borsodi ártér’ microregion. We provide data on the stands of Thelypteris palustris observed along the main irrigation canals of ‘Tiszántúl’ region. We publish new occurrence records contributing to the Hungarian distribution of Aethionema saxatile, Crataegus nigra, Elatine hungarica, Sium sisarum, Orobanche hederae, Himantoglossum adriaticum, Epipactis placentina, E. exilis, E. pseudopurpurata, and E. microphylla, as well as to the appearance of Helosciadium repens in urbanized environment. Gagea spathacea and G. bohemica are newly recorded for the Zemplén Mts; Epipactis nordeniorum and Epipogium aphyllum are new for the flora of the Mátra Mts; and Himantoglossum calcaratum is newly recorded for Hungary. We also present spontaneous establishment of several orchid species in the courtyard of a secondary school in Veszprém. Additionally, we report on the pollinating insects observed on the flowers of Sternbergia colchiciflora. Two previously misreported records are also corrected.

Contributions to the flora of Budapest and its surroundings III.
227–237Views:553New or recently confirmed localities of 40 rare taxa (including 7 ferns) are presented from the vicinity of Budapest. Some records are new for the flora of particular regions, specifically: Geranium sibiricum (Buda Mts and Budapest), Polystichum setiferum (Pilis Mts), Onosma pseudarenaria, Sorbus aria s. str. (Visegrad Mts). Of the remaining records, the most significant ones are those of Agrimonia procera, Botrychium lunaria, Epipactis tallosii, Gymnadenia odoratissima and Sorbus ujhelyii.

Fern (Pteridopsida) flora of South Nyírség (East Hungary)
162–182Views:620The study presents a number of new data on the fern flora of South Nyírség, and reviews all available literature and herbarium fern records from the area. A total of 19 Pteridopsida species were detected in the region. The hart's tongue fern (Asplenium scolopendrium) and the soft shield fern (Polystichum setiferum) were hitherto unknown in the whole Nyírség region (flora district “Nyírségense”). The broad buckler-fern (Dryopteris dilatata), scaly male fern (Dryopteris affinis) and floating fern (Salvinia natans) are new records to the area of South Nyírség. Dryopteris dilatata has been found in a surprisingly great number of localities. Some morphological characters facilitating identification of this species are also discussed. The local pine plantations, fens, carrs and humid deciduous forests are important habitats for ferns. In some localities the co-occurrence of 5-6 fern species were observed. The increasing aridity in the last decade is posing a serious threat to ferns in the area.

Data on the distribution of some protected plant species and on their presence in secondary habitats
183-199Views:2247In this paper, I publish my floristic data on some protected and strictly protected plant species collected in Hungary between 2016 and 2021. The data published in this paper cover 31 micro regions of Hungary, but most of them come from the Great Hungarian Plain, especially from Pest and Bács-Kiskun counties. I describe the occurrences of 41 protected and three strictly protected vascular plant species (two ferns and 42 flowering plants), some of which represent new data for the particular micro region or even larger geographical areas (e.g. Botrychium matricariifolium, Thlaspi alliaceum and Nasturtium officinale). For some species, the published data either come from floristically understudied areas (e.g. Ranunculus illyricus, Vinca herbacea and Cardamine amara) or are considered rare in the certain region and/or in the whole country (e.g. Apium repens, Cnidium dubium and Vicia narbonensis). For other species, the newly reported occurrences are presented as complement to the already known distribution data (e.g. Cephalanthera damasonium, C. rubra, Linaria biebersteinii, Sonchus palustris and Agrostemma githago). In support of the nature conservation actions, I provide data from the flora of some floristically understudied micro regions (e.g. Dorozsma-Majsai Sand Ridge, Bácskai Loess Plain) and try to highlight the role of canals in Hungary in species and biodiversity conservation, by the example of the Danube-Tisza canal. In this manuscript, I publish data on twelve protected plant species from the Danube-Tisza canal and its canal bank (eg. Peucedanum palustre, Carex paniculata, Clematis integrifolia).

Occurrence of ferns in secondary habitats of the Great Hungarian Plain
3–14Views:799In 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.

Contributions to the flora of Budapest and its surroundings IV.
27–40Views:841New or recently confirmed localities of more than 50 rare or poorly known taxa (including 10 ferns) are presented from the territory of Budapest and adjacent territories. Some of those records are new for the spontaneous flora of particular territories, specifically: Anthericum liliago (Szentendre Island), Artemisia alba (Tétény Highland), Cerastium lucorum (Buda Mts, Börzsöny), Epipactis albensis (Budapest, Pilis), E. futakii (Börzsöny), E. moravica (Börzsöny, Visegrád Mts), Hippophae rhamnoides (Szentendre Island), Myosotis discolor (Börzsöny). The new localities of Cnidium dubium, Platanthera chlorantha, Spiranthes spiralis, Sternbergia colchiciflora, Veronica jacquinii and Viola stagnina are also noteworthy. Some species are discussed in more detail in relation to their former Hungarian literature records.
