Polystichum acrostichoides
''Polystichum acrostichoides'' (Christmas fern) is an evergreen fern native to eastern North America from Nova Scotia west to Minnesota and south to Florida and eastern Texas. 〔(USDA ) . accessed 11.1.2011〕 It is one of the most common ferns in eastern North America, being found in a wide variety of habitats and locations.
==Description==
The common name of ''Polystichum acrostichoides'', Christmas fern, derives from its evergreen fronds, with fronds growing to 30-80 cm long and 5-12 cm broad, divided into 20-35 pairs of pinnae. The spores are produced on small pinnae toward the apex of the frond.
Christmas fern resembles the Pacific Coast sword fern, ''Polystichum munitum'', but does not make the huge clumps of that fern, and differs from it in the constriction of the fertile pinnae. Like other ferns of the genus ''Polystichum'', it is allied to the wood ferns, genus ''Dryopteris'', to which it is often found growing in close proximity.
