Rhizome: creeping, branching, slender, to 2 mm diam., scales lanceolate, base and margins light brown, with dark central stripe, clathrate toward center.
Frond: 25 cm high by 5 cm wide, evergreen, monomorphic, blade/stipe ratio: 3:2.
Stipe: jointed at base, straw-colored, grooved, densely scaly when young, falling soon; scales often overlapping, margins mostly entire, vascular bundles: 3.

Pinnae: 8 to 14 pair, linear, entire, blunt at the tip, about 3 mm wide by 25 mm; margins entire; veins mostly free with occasional netting.
Sori: round, discrete, sunken, protruding on the upper surface, midway between margin and midrib to nearly marginal; on all but the lowest pinnae of fertile fronds, indusium: absent, sporangia: yellow to brown at maturity.
Habitat: epiphitic in the southern part of the range, epipetric in the northern area.
Distribution: southeastern United States.
Hardy to -20°C, USDA Zone 6.
