Description
A description of Asplenium platyneuron is provided in The Flora of North America.
It can be easily confused with Christmas fern (Polystichum acrostichoides); however, the stem of Christmas fern is green and scaly and the spores cover a back of a leaflet.[2]
Distribution
It is one of the most common and widespread of the eastern North American spleenwort.[3] Listed as critically imperiled in Arizona and Colorado.[4]
Ecology
Habitat
Habitats include rocks, rotting logs, swamps, marshes, crotches of hardwood trees, and savannas.[5][6] It also grows in disturbed areas such as fallow fields and near field edges. It does well in moist, loamy sand in fully shaded environments to areas with full sun.[6]
Associated species include cypress, moss, magnolia, oak, and beech.[6]
Phenology
Reproduces with proliferating buds that form near the base of the stipe and when covered with soil, can grow into new individuals as the frond that bore them dies. Also propagates by spores and can hybridize with other spleenworts.[7] It has been observed flowering in February.[8]
Fire ecology
It does well in fire dependent environments.[6] However, one study found that A. platyneuron had little to no change in frequency in response to prescribed fire.[9]
Pollination and use by animals
Asplenium platyneuron is fed on by two aphids: Amphorophora ampullata and Idiopterus nephrelepidis.[10]
Conservation, cultivation, and restoration
It is listed as a species of special concern by the Maine Department of Conservation, and listed as exploitably vulnerable by the Division of Land and Forests in New York.[11]
