Phegopteris hexagonoptera, commonly called the broad beech fern, is a common forest fern in the eastern United States and adjacent Ontario. It grows from a creeping rootstock, sending up individual fronds that more or less clump. The fronds are broadly triangular. The specific name hexagonoptera refers to the winging of leaf tissue along the rachis between the basal pinnae. Rare hybrids with Phegopteris connectilis are known. This fern makes an excellent garden plant, gradually filling in a bed.
