Walking Fern
Walking fern, Asplenium rhizophyllum, is found in many places in the Eastern and Central United States, and around the Great Lakes, but it is not that common.
iNaturalist map of A. rhizophyllum
A. rhizophyllum is a singular fern. Its frond is not cut.
The distinguishing trait of A. rhizophyllum is the frond is very pointed. Where the point touches ground, a new plant grows. This repeats, and the group of plants 'walk' across the land.
Found mostly on rocks.
