Dryopteris

have prominent scales.

Hybridization and polyploidy are well-known phenomena in this group, with many species formed via these processes. The North American Dryopteris hybrid complex is a well-known example of speciation via allopolyploid hybridization.[7]

Selected species

The genus has a large number of species. The PPG I classification suggested there were about 400 species;[3] as of February 2020, the Checklist of Ferns and Lycophytes of the World listed 328 species and 83 hybrids.[1] Some genera sunk into Dryopteris, such as Dryopsis, Stenolepia and Nothoperanema, are distinguished by other sources.[1]

Ecology

Dryopteris species are used as food plants by the larvae of some Lepidoptera species including Batrachedra sophroniella (which feeds exclusively on D. cyatheoides) and Sthenopiseauratus.

Cultivation and uses

Many Dryopteris species are widely used as garden ornamental plants, especially D. affinis, D. erythrosora, and D. filix-mas, with numerous cultivars.

Dryopteris filix-mas was throughout much of recent human history widely used as a

vermifuge, and was the only fern listed in the U.S. Pharmacopoeia
. Traditional use in Scandinavia against red mite (Dermanyssus gallinae) infestation is to place fronds in nesting boxes under nesting material and under floor covering material.
