Gymnocarpium

See text Gymnocarpium is a small genus of ferns, called oak ferns.

Cladistic analysis has demonstrated that Gymnocarpium and Cystopteris form a natural but relatively primitive clade that is basal to the asplenioid, thelypterioid, and athyrioid ferns comprehensively.

Gymnocarpium sori are small, round and naked.

These ferns generally have a slender, creeping rhizome under the surface of the ground, and fairly thin-textured fronds.
