Rootstocks creeping, filiform, stipes ascending, one to three inches long, thin, very delicate, pellucid, much divided, oblong-lanceolate, bipinnatifid. Rachis narrowly winged. Sporangia clustered around the slender bristle, which is the prolongation of a vein, and surrounded by a vase-like, slightly two-lipped involucre.
On moist, dripping sandstone cliffs, Kentucky to Alabama. Often called the “Killarney fern,” as it grows about the lakes of Killarney in Ireland.
