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.
Many are cultivated as ornamental plants.
