During field studies in 2019 in the Beskid Śląski mountain range in southern Poland, one individual morphologically resembling <em>Polystichum setiferum </em>was found. Nuclear DNA content analysis confirmed the species identity. The new stand of <em>P. setiferum </em>corresponds to historical literature reports and herbarium specimens from the Czech Republic and Poland, and extends the northeastern limit of the distribution of this species. As the historical stands in both countries have not been confirmed, the newly discovered stand is at present strongly isolated, as the nearest extant locations of <em>P. setiferum </em>in Austria, southern Hungary, and western Romania are nearly 500 km away. Therefore, this unique stand deserves special attention and protection.
Streszczenie
Na terenie Miejskiego Ogrodu Botanicznego w Zabrzu zgromadzono 33 taksony (w tym 27 gatunków) rodzimych paproci, należących do 9 rodzin. Większość tych paproci rośnie na dwóch pagórkach w południowo-centralnej części ogrodu, a pozostałe w stawach w południowo-zachodnim i południowo-wschodnim jego sektorze. Jest to pierwsze opracowanie opisujące kolekcję rodzimych taksonów paproci w polskim ogrodzie botanicznym.
