Berol. 2 : 69. 1833. Rootstock short, usually creeping, somewhat chaffy. Stipes light green, i'-6' long, tufted, spreading; blades evergreen, 4'-g' long, rather thin or somewhat chartaceous, simple, lanceolate, the bases usually cordate or auriculate, sometimes hastate, the basal auricles occasionally much elon- gate, the apex of the blade long-attenuate and usually filiform, rooting at the tip and giving rise to a new plant by the ultimate withering of the tissue, but 2-4 plants sometimes thus connected; sori usually numerous, irregularly placed. In shaded situations, usually upon moist mossy rocks, preferring limestone, Quebec to Minnesota, Georgia, Alabama and Kansas. Ascends to 2500 ft. in Virginia. Called also Walking-leaf. 12.
