Inside a fenced-in area of woodland, so not subject to the browsing of deer. [Regrettably, in the unenclosed areas, even the steep bank of the stream is browsed to perdition.]
This Athyrium species has one extra level of frond division than seen in described species of Athyrium of Eastern North America. That is to say, the leaflet is essentially the usual, but small, frond of an Athyrium.
This species has been observed at
Pike County, Ohio
