Walking fern, fern that is a
member either of the species Asplenium
rhizophyllum, of eastern North America, or of A. sibiricum, of
eastern Asia, in the family Aspleniaceae.
The common name derives from the fact that new plantlets sprout wherever the
tips of parent plant’s arching leaves touch the ground. The plant’s leaves are
evergreen, undivided, and slightly leathery; they are triangular in shape, tapering
to a thin point. Spore-bearing structures are in clusters along the veins.
Walking ferns are hardy plants that inhabit shady areas of limestone ledges and
limey wooded areas.
