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.[1]

Distribution

It is one of the most common and widespread of the eastern North American spleenwort.[2] Listed as critically imperiled in Arizona and Colorado.[3]

Ecology

Habitat

Habitats include rocks, rotting logs, swamps, marshes, crotches of hardwood trees, and savannas.[4][5] 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.[5]

Associated species include cypress, moss, magnolia, oak, and beech.[5]

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.[6]

Fire ecology

It does well in fire dependent environments.[5]

Use by animals

Is fed on by two aphids: Amphorophora ampullata and Idiopterus nephrelepidis.[7]
