Common name: Ebony spleenwort
Synonyms: Asplenium platyneuron var. platyneuron; A. platyneuron var. bacculum-rubrum (Featherman) Fernald; A. platyneuron var. incisum (Howe ex Peck) B.L.
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.
Habitats include rocks, rotting logs, swamps, marshes, crotches of hardwood trees, and savannas. 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.
Associated species include cypress, moss, magnolia, oak, and beech.
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.
It does well in fire dependent environments.
Use by animals
Is fed on by two aphids: Amphorophora ampullata and Idiopterus nephrelepidis.
