Taxonomy Comments: This species is one of the diploid "parent species" of the e. North American reticulately-evolved Dryopteris complex. Its genome (symbolized LL) forms half of the genome of the tetraploids D. cristata and D. celsa, as well as contributing one third of the genome of D. clintoniana indirectly (via its daughter species D. cristata).
