The Dryopteridaceae is a family of ferns with a cosmopolitan distribution.
All of the fronds of Dryopteridaceae ferns contain round sori (reproductive clusters) on the underside of the pinnae (leaflets) unlike some other ferns which have separate specialized reproductive fronds. Many of the sori have peltate indusia. Most have prominent scales on the stipes of the fronds. Many have stout, creeping rhizomes.
The Dryopteridaceae is a large and diverse fern family with a near cosmopolitan distribution. Arachniodes (East Indian holly fern), Cyrtomium (net-veined holly fern), Didymochlaena (tree maidenhair fern), Dryopteris spp. (shield, buckler, wood or oak ferns), Nothoperanema (bristle fern), Polystichum (holly fern) and Rumohra (seven weeks fern) are some of the genera belonging to the family and which have representatives in the South African flora. Although only a few species occur in South Africa, these genera have approximately 570 species worldwide.
Many are cultivated as ornamental plants.
