Amauropelta noveboracensis
Amauropelta noveboracensis, the New York fern, 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. Description This fern grows in clumps of three or more fronds along a dark brown, slightly scaly rhizome. The frond is held on a stipe which is 20% of the length of the leaf and brown at the base but becoming green as it approaches the leaflets. The stipe is typically covered in brown scales at the base and finely hairy farther up. The leaf is overall long, yellow-green, rather soft and thin in texture, and tapers at either end with the lowest 4-10 leaflets being generally smaller than those above. The leaf is divided into approximately 20 pinnae or leaflets, these leaflets are deeply cut into smaller, oblong and rounded subleaflets. It produces both fertile and sterile fronds—the fertile fronds are larger and more upright, and produce a few small, round sori near the margins, but not touching the margins, of the pinnae. These sori are covered by a tan, hairy, kidney-shaped indusium. It
