Gymnocarpium is a small genus of ferns once placed with various other groups including the dryopteroid ferns and the athyrioid ferns. Cladistic analysis has demonstrated that Gymnocarpium and Cystopteris form a natural but relatively primitive clade that is basal to the asplenoid thelypterioid and athyrioid ferns comprehensively.Gymnocarpium sori are small round and naked.
