''Gymnocarpium robertianum'' (limestone oak fern or scented oak fern) is a fern of the family Woodsiaceae. ==Description== ''Gymnocarpium robertianum'' has small (10-50cm), deltate, two to three pinnate fronds. Fronds arise from creeping rhizomes and have long, delicate rachis. The sori are borne in round clumps on the underside of the blade and lack an indusium. This species differs from the closely related ''G. dryopteris'' in having a densely glandular rachis as well as a more sparsely glandular underside to the blade.〔Stace C. (1997). New Flora of The British Isles, second edition. Cambridge: Cambridge University Press〕 ''G . robertianum'' is thought to hybridise with ''G . appalachianum'' giving rise to ''Gymnocarpium'' × ''heterosporum'' W. H. Wagner. This hybrid was only known from Pennsylvania where it has now been eradicated. The hybrid between ''G. robertianum'' and ''G. dryopteris'' is ''Gymnocarpium'' × ''achriosporum'' Sarvela this taxon is known from Sweden and Quebec.〔(''Gymnocarpium robertianum'' ) at Flora of North America〕
