Dryopteris intermedia, the intermediate wood fern or evergreen wood fern,[4][3] is a perennial, evergreen wood fern native to eastern North America. It is a diploid species, and is the parent of several species of hybrid origin, including Dryopteris carthusiana. Other common names for this species include intermediate shield fern, fancy wood fern, fancy fern, glandular wood fern, American shield fern and common wood fern.[2][3][5][6]
This fern is often confused with several other wood fern species, including D. carthusiana, D. campyloptera, and D. expansa. It especially extensively shares the range of D. carthusiana, but the two may be distinguished by the innermost pinnule on the bottom side of the bottom pinna: this pinnule is longer than the adjacent pinnules in D. carthusiana, but shorter or even in D. intermedia.
