1. Key to identification and descriptions of species of Buckler-ferns (Dryopteris Adans.) occuring in Poland

Ewa Szczęśniak, Dariusz Tlałka, Adam Rostański


Abstract: According to the newest research, the genus of Buckler-ferns (Dryopteris Adans.) is represented in Poland by 9 species, including 1 extinct in the wild. Presented paper includes the key to all of the Dryopteris species native in Poland, their detailed descriptions and photographs of features of taxonomic importance. A list of known hybrids and descriptions of the most common ones are also included.

Key words: Buckler-ferns, Dryopteris Adans., key to identification 

2. Occurrence of the species of Dryopteris Adans. in Beskid Mały in the Western Carpathians

Dariusz Tlałka


Abstract: Beskid Mały is a relatively small and low range in the Beskid massif, the Outer Western Carpathians, South Poland. The paper presents current distribution of the Dryopteris taxa in Beskid Mały, based on the cartogram method using 2×2 km ATPOL squares. Up to now, 110 squares with stands of all the taxa have been presented in the ATPOL data base. As a result of current research, distribution of  Dryopteris taxa is shown in 548 squares. The genus is represented within the investigated area by six species: D. borreri (Newm.) Oberh. et Tavel of the D. affinis (Löwe) Fraser-Jenk. agg. . in 113 squares, D. carthusiana (Vill.) H. P. Fuchs . 117, D. dilatata (Hoffm.) A. Gray . 117, D. expansa (C. Presl) Fraser-Jenk. et Jermy . 70, D. filixmas (L.) Schott . 117 and the rarest one, D. remota (A. Braun in Döll) Druce, in 14 squares.

3. Morphological diversity of ferns in the Dryopteris affinis group in Central Poland

Beata Woziwoda


Abstract: The article presents the morphological diversity of individuals from Dryopteris affinis group, which grow in 8 isolated localities in the Łaska Upland (Central Poland). It contains descriptions and comparison of 17 morphological features that are often used as diagnostic in manuals. The studied ferns represent two species: D. borreri (Newm.) Oberh. & Tavel and Dryopteris cambriensis (Fraser-Jenk.) Beitel & W.R. Buck, which means that D. affinis (Löwe) Fraser-Jenk. s. s. has not been found in this area so far.

4. New localities of Dryopteris affinis agg. (Dryopteridaceae) in the Kielecka Upland (south-eastern Poland)

Marek J. Podsiedlik


Abstract: The paper presents the distribution, phytosociological preferences and size of populations of scaly male fern Dryopteris affinis agg. in the Kielecka Upland. Seven new localities of this species are described near Bobrza, Kielce, Miedziana Góra, Niestachów and Zelejowa. This fern grows here in the following associations: submontane mesotrophic fir forest Abietetum polonicum (Dziub. 1928) Br.-Bl. et Vlieg. 1939 and alder-ash forest Fraxino-Alnetum W. Mat. 1952, in the communities from the classes Rhamno-Prunetea Rivas-Goday et Grab. 1961 and Vaccinio-Piceetea Br.-Bl. 1939, moreover it occurs in plantations of Abies alba, Pinus sylvestris and Populus tremula. Stands consist of one or two individuals.

5. The Dryopteris Adans. species in Wrocław (SW Poland) - occurrence and distribution in urban habitats

Ewa Szczęśniak


Abstract: The species composition, distribution and dynamics of the spontaneous Dryopteris flora were examined in Wrocław, a typical large city in Central Europe. In the course of current and previous surveys, four taxa were identified. Dryopteris cristata (L.) A. Gray was not found in the present research, and thus its previous stands were not confirmed; this species is presumed to have become extinct in the city. Dryopteris dilatata (Hoffm.) A. Gray occurs in four localities, all in woodlands: forests and sporadically in abandoned parks; it does not enter typical urban habitats. Dryopteris carthusiana (VIll.) H. P. Fuchs is more common; it was observed in forests, parks and occasionally on scattered sites in the industrial part or in the city centre. These two taxa seem to be urbanophob or moderately urbanophob species. Dryopteris filix-mas (L.) Schott is the most popular species, which occurs in woodlands and typical urban habitats on old walls in all urban zones. It seems to be a neutral taxon in respect of urban habitats.

6. Ornamental ferns of the genus Dryopteris Adans.

Elżbieta Zenkteler


Abstract: This review is concerned with .cultivars. (i.e. cultivated varieties) of ferns which arose through selection and differ morphologically from the typical plants of the species by some growth and phenotype characteristics. The variants occur more or less frequently within natural populations and if they become well established in culture, they can be considered as cultivars, and may be very interesting to fern growers. Variability of ferns includes modifications of growth habit and frond features such as the presence of divided lobes or crests. Many fern cultivars are vegetatively propagated, some are apogamous and other can be propagated from spores. Tissue culture is also a possible means for their multiplication.

7. Collection of the genus Dryopteris Adans. in the Herbarium of the University of Silesia (KTU)

Adam Rostański, Izabela Śmietańska-Gerold


Abstract: It has been 35 years since the foundation of the KTU Herbarium. Today, the herbarium contains more than 120 000 specimens. This fact makes the herbarium and its collection one of the medium-sized herbaria in Poland. An important proportion of the collection includes specimens of different pteridophytes (Pteridophyta). In 2009, the collection contained 2645 herbarium specimens of ferns and club mosses. The genus Dryopteris is represented by 8 species (551 specimens). Since 2008, a part of the herbarium database (including ferns) has been accessible through the website of the Global Biodiversity Information Facility (GBIF).

8. Pteridological field-trip to the Beskidy Zachodnie range (Southern Poland), a refuge of natural habitats of ferns and fern al

Zbigniew Wilczek, Dariusz Tlałka, Adam Rostański


Abstract: More than a half of Polish native pteridophyte species occur in the Beskidy Zachodnie range, where habitat conditions are suitable for their development. Among them, the genus Dryopteris Adans. is represented by 7 species, i.e. by almost all extant taxa occurring in Poland. The paper presents the route of the fieldtrip organised during the First Polish Pteridological Workshop “Genus Dryopteris in Poland” by the Polish Botanical Society, and description of chosen stands.
