Asplenium ceterach s.str. and Polystichum aculeatum on the ruins of the copy of Eger Castle, in the Pilis Mts
93-94Views:246In 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.

The biases of floristic surveys I. Naive planters: “cuckoo” of the Medves (N Hungary)
207-217Views:145The aim of the planned thematic studies is to point out the main biases and/or errors of floristic surveys in Hungary. In this first article of the series we focus on those examples when native species were planted out of their original habitats and/or range by a non-professional naturalist. The sources of information are those letters that were posted by Ferenc Varga to the first author of this article in 2005. The circumstances of the transplantation of 10 phytogeographycally significant species of the investigated area and/or the Pannonicum (Adonis vernalis, Arum orientale, Asarum europaeum, Genista germanica, Phragmites australis, Pulsatilla grandis, P. nigricans, Salvia aethiopis, Viola alba, Xeranthemum annuum) are detailed in the text and summarised in a table. The correspondence between the first author and Ferenc Varga provides insight how the ambition of a non-professional naturalist can influence the flora of an area. Most of the species were removed from South and transplanted to North, almost 10 km away from their original stands. With the exception of Adonis vernalis and Genista germanica at least one transplantation of the species was successful. In the case of Salvia aethiopis, the naturalized populations came 1.25 km close to Slovakia, where this species is a very rare and endangered (EN) taxon.

Distribution of Campylopus introflexus (Hedw.) Brid. in Hungary
212-219Views:117Based on field work data collected in 2013–2014, the authors generated a map of the current distribution of Campylopus introflexus for Hungary. Besides the coordinates and geographic name of the localities, an estimated size of the population, the type of habitat and substrate, the co-occurring moss species and affected vegetation types were also recorded. Altogether, 18 stands were found in 8 geographical regions of Hungary, in some cases Campylopus introflexus was found to be a new species record for the moss flora of the respective region (e.g. Dunántúli-dombság, Nyugatmagyarországi peremvidék). In addition to the pine plantations from where it was detected formerly, the mixed deciduous-coniferous forests, the acidophilous oak woodlands and man-made habitats were found to be also proper habitats for this moss taxon. Earlier data mainly originated from pine deadwood, the recently discovered stands were found on acidic soil surfaces. The most important cooccurring moss species were the followings: Hypnum cupressiforme, Polytrichum piliferum, P. formosum, Pohlia nutans and Ceratodon purpureus. Campylopus introflexus had prominently high coverage in the acidophilous oak forests of the Mecsek Mts, where it occurs on acidic sandstone covered with a thin debris of the bedrock. This neophyte moss is widely distributed in Hungary, and has stable populations. Further expansion is expected in the subatlantic and submountain regions of the country, and in regions characterised by acidic soils and pine plantations.
