    The other and older generic name for this plant is Thelypteris. The present generic name comes from Greek meaning "phegos" = beech & "pteris" = fern. Its native range is from southeast Canada, Maine into Florida to east Texas through eastern Kansas through Minnesota in shady, moist to wet locations. It spreads by hairy, branching rhizomes with yellow or light brown scales, and it can spread aggressively in a favorable situation. It has triangular, medium-green fronds that tilt back usually and are twice compound. Its fertile fronds bear the sori, the rounded or kidney-shaped spore producing structures, are under the leaflets and the sterile fronds look the same, except without sori. The frond stalks have scales and the veins in the leaflets go to the edge of the blade. I've only seen this species once at Jenkins Arboretum in southeast Pennsylvania in their fern collection in their native forest. Some native plant nurseries may sell this species. I've never seen it sold in conventional nurseries.
