Gymnocarpium (family Aspleniaceae) A genus of ferns that have no indusium to the rounded, superficial sori; creeping rhizomes; and fronds that often appear 3-lobed because the lowest pair of pinnae are each nearly as large as the rest of the frond. There are 6 species in the northern temperate zone (e.g. oak fern), which are sometimes cultivated.
