Origin/Endemic status: Native

Taxonomy Comments: High elevation plants (mainly in spruce-fir and northern hardwoods forests) in the Southern Appalachians need additional taxonomic study. They have much larger leaves than typical lowland forms, and the leaves are more divided. The name Athyrium filix-femina var. subtripinnatum Butters may apply.
