Phegopteris connectilis, commonly known as long beech fern, northern beech fern, and narrow beech fern, is a species of fern native to forests of the Northern Hemisphere. This species is often epipetric as well as terrestrial.
Phegopteris connectilis, commonly known as narrow beech fern, is a deciduous fern that typically grows to 8-18” tall with a slow outward spread over time by creeping rhizomes to 36” wide. It is a circumboreal species which is native to moist woodland areas and stream banks in northern parts of North America, Europe and Asia. In the U.S., it is native from Alaska to Newfoundland and Greenland south to Oregon, Iowa, western Illinois, Michigan and in the Appalachians to North Carolina. Narrow triangular blade is pinnate-pinnatifid to bipinnatifid extending to 14” long and 9” wide. Each leaflet is narrow triangular with a tapering tip. The bottom pair of leaflets is disjunct from the pair above it and is usually significantly downturned. Sori are located near the margins. No indusium (flap which usually covers the fern sori).
