Dryopteris

See text

Dryopteris is a genus of about 150 species of ferns with distribution in the temperate northern hemisphere. Many ferns of this genus have stout, slowly-creeping rootstocks that form a crown, with a vase-like ring of fronds. The sori are round, with a peltate indusium. The stipes have prominent scales.

Hybridization is a well-known phenomenon within this group, with many species are formed by hybridization.

Many Dryopteris species are highly desired as garden ornamentals, especially the following:

• D. erythrosa - autumn fern, often sold in garden outlets
• D. filix-mas - a very popular garden fern in the British Isles and Europe, with very many 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.
