Dryopteris cristata
''Dryopteris cristata'' (L.) A. Gray is a species of fern native to wetlands throughout the Northern Hemisphere. It is known as crested wood fern〔U.S. Department of Agriculture. 2009〕 or crested buckler-fern. This plant is a tetraploid species of hybrid origin, one parent being ''Dryopteris ludoviciana'' and the other being the unknown, apparently extinct species, dubbed ''Dryopteris semicristata'', which is also one of the presumed parents of ''Dryopteris carthusiana''. ''D. cristata'' in turn is one of the parents of ''Dryopteris clintoniana'', another fern of hybrid origin.
The crested wood fern is a wetlands plant, needing year-round moisture. The fronds often grow quite tall, up to a meter or more in height, but are extremely narrow under most conditions.
==Anti-microbial properties==
It is known that this plant has been used as an anti-microbial agent; for example, root extracts from ''D. cristata'' (as well as the kindred species ''D. arguta'') has been shown efficacious in expelling intestinal parasites from certain mammals.〔C. Michael Hogan. 2008〕
