Phegopteris hexagonoptera (Michx.) Fée
Broad Beech Fern
Habitat: Rich, often rocky, hardwood forests. [Hardwood to mixed forest (forest, upland)]
Range: Quebec and Maine to Ontario and Minnesota, south to northern Florida and Texas.
Aids to Identification: Broad beech fern is a large fern with triangular blades, which grows to about 60 cm in height. It is pubescent with transparent, needle-like hairs and has narrow, light colored scales. Most similar looking ferns are scaley rather than hairy. It is slightly hairy and a dull green color. It is distinguished from its close relative long beech fern (P. connectilis) by the entirely winged axis and subleaflets with distinct lobes.
Ecological characteristics: Generally found in sunny, more open spots in moist woods.
Phenology: Fruits in August.
Synonyms: Dryopteris hexagonoptera (Michx.) C. Christens.; Thelypteris hexagonoptera (Michx.) Weatherby.
Known Distribution in Maine: This rare plant has been documented from a total of 29 town(s) in the following county(ies): Androscoggin, Aroostook, Cumberland, Franklin, Kennebec, Knox, Oxford, Somerset, York.
Reason(s) for rarity: At northern limit of range.
Conservation considerations: Effects of logging are unknown. Partial removal of the canopy might benefit the plant by allowing more light to the forest floor; complete removal of the canopy would be more likely to be detrimental because it would bring more drastic habitat change.
