Walking Fern
Asplenium rhizophyllum
biota:
Walking Fern
Walking Fern has a tapering leaf, maybe as much as three or four inches long. The pointed end can root and form a new plant. Usually the original plant remains alive, so that the result can be a colony of individuals that forms as they slowly "walk" across the face of the rocks that they root on. Found on limestone or sandstone rocks, often in wet ravines.
