(Muhl. ex Willd.) A.Gray. - fancy wood fern, evergreen wood fern Common in wide range of mesic forests, upland woods, hummocks in swamps, rocky woodlands, on slopes, in ravines, and in moist pockets on cliffs. Flattened green fronds broken by snow in winter often surround emerging fiddleheads of this fern in spring. The tiny glandular hairs on the indusia and scattered on costae are diagnostic features of this species. These glands appear on its hybrids with D. carthusiana, with D. clintoniana, with D. marginalis, with D. expansa, and with D. goldiana.
- innermost downward pointing pinnules on the lowermost pinnae the same length or shorter than the adjacent pinnules
