    New 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.

    In 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.
