Annotation
Na území ČR bylo studováno rozšíření zástupců skupiny Dryopteris affinis. Byly zjištěni dva zástupci (Dryopteris borreri, D. cambrensis) a jeden kříženec (D. × critica - D. borreri × D. filix-mas). D. cambrensis je vzácným druhem, byl v ČR zaznamenán jen na 29 lokalitách a je poprvé uváděn pro Čechy.
Description in English
The distribution of taxa of the Dryopteris affinis group in the Czech Republic was studied. Collections of 25 Czech public herbaria were revised and a total of 373 specimens were examined. Two species, D. borreri and D. cambrensis, and one hybrid, D. × critica (D. borreri × D. filix-mas), were recorded in the Czech Republic. D. cambrensis was recently rediscovered for the flora of the Czech Republic after more than 30 years and was recorded as a new species to Bohemia. Twenty-eight localities of the rare D. cambrensis are known from the Czech Republic. An overview of the morphological characters and habitat preferences, distribution maps, the total distribution of the taxa and an identification key are presented.
