Dryopteris carthusiana
Also called Narrow buckler-fern, Spinulose Wood Fern, Toothed Wood Fern, Narrow Spinulose Shield Fern, Spinulose Shield Fern, Toothed Woodfern
Spinulose woodfern is a hardy, mostly deciduous perennial fern from damp forests across the Northern Hemisphere, with upright, dark green fronds. It grows best in acidic, moist woodland conditions and tolerates more sun than many other ferns.
Dryopteris carthusiana is a perennial species of fern native to damp forests throughout the Holarctic Kingdom. It is known as the narrow buckler-fern in the United Kingdom, and as the spinulose woodfern in North America.
It is a tetraploid of hybrid origin, one parent being Dryopteris intermedia, known in North America as the intermediate wood fern, and an unknown, apparently extinct species dubbed Dryopteris semicristata, which is also the presumed parent of the hybrid-origin Dryopteris cristata.
The plant favors acidic ground and even avoids lime rich soil and spring areas favored by many other pteridophyta. It can tolerate direct sunlight slightly better than its relatives and can therefore survive even in some logging sites and benefit from them. It grows often in the following habitats: moist depressions in forests, nemoral forests, coastal scrubs, fresh cliff faces, sides of ditches, coniferous swamps and herb-rich hardwood-spruce swamps (ruohokorpi in Finnish).
