Amauropelta noveboracensis, the New York fern, [3] is a perennial species of fern found throughout the eastern United States and Canada, from Louisiana to Newfoundland, but most concentrated within Appalachia and the Atlantic Northeast. New York ferns often forms spreading colonies within the forests they inhabit.
The fern has spores on the bottom of the fronds, contained in sori. Sori can be found aligned in rows on the underside of fertile fronds. They start as yellow, but as they mature, they turn brown and split. [13] The fern sporulates in summer and early fall. Rhizome sections are also viable offspring and can root themselves in new medium.

Asplenium rhizophyllum plantlet sprouting from the leaf apex of its parent plant. The stipe (the stalk of the leaf, below the blade) is 0.5 to 12 centimetres (0.20 to 4.7 in) long [2] (occasionally up to 15 centimetres (5.9 in) long), and ranges from one-tenth to one and one-half times the length of the blade.
Matteuccia is a genus of ferns with one species: Matteuccia struthiopteris (common names ostrich fern, fiddlehead fern, or shuttlecock fern). [4] The species epithet struthiopteris comes from Ancient Greek words στρουθίων ( strouthíōn ) "ostrich" and πτερίς ( pterís ) "fern".
[18] [19] An introduced population descended from New York plants is found in New Jersey; it is a remnant of a 1936 effort to practice ex-situ conservation of populations in New York. [20] In 2020, a new population of hart's-tongue ferns was discovered inside a cave with basaltic lava flows in El Malpais National Monument, Cibola County, New ...
Coryphopteris simulata, synonym Thelypteris simulata, [2] is a species of fern native to the Northeastern United States. It is known by two common names: bog-fern and Massachusetts fern. It is often confused with the silvery spleenwort, New York fern, and the marsh fern due to similarities in shape and size. [3] [4]
But other clump-forming tree fern species, such as D. squarrosa and D. youngiae, can regenerate from basal offsets or from "pups" emerging along the surviving trunk length. Tree ferns often fall over in the wild, yet manage to re-root from this new prostrate position and begin new vertical growth.
