  In the company of a single individual of Asplenium trichomanes L., several individuals of Asplenium ruta-muraria (L.) Hoffm. and a single individual of Dryopteris filix-mas (L.) Schott, 15 individuals of Asplenium ceterach L. (s.str.), and a single individual of Polystichum aculeatum (L.) Roth were found on a NW facing mortared sandstone wall of the copy of Eger Castle in the Pilis Mts. Asplenium ceterach s.str. is new to the flora of the Pilis Mts. The source population of this stand is probably located in the Buda Mts (Remete gorge) and this fern may have appeared on this wall 5–10 years ago at the latest.

  New 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.

  The 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.
