Rhizome rather slender, creeping, clad in dark to bright brown subulate-attenuate paleae, c. 3 mm. long; stipites often approximate. Stipes rather stout, black-brown, scabrid, ± clad in slender hairs, paleate in lower portion, 10-30 cm. long. Rhachis similar, flexuose, ± clad in dark to fulvous stiff hairs, as are secondary rhachides and costae. Lamina ovate-deltoid to deltoid, 2-3-pinnate, 15-40 × 7-24 cm., olive to pale green, firm; lower surface ± clad in setulose hairs. Primary pinnae up to 15 × 7 cm., alt. distant, ovate-deltoid, with 2-4 lateral and a terminal pinna. Secondary pinnae rather distant, up to 8 × 2 cm. Pinnules up to 2.5 cm. × 5 mm., very shortly stalked, approximate, dimidiately narrow-oblong, ± subfalcate; lower margin entire, concave-convex; upper margin with alternately shallow and rather deep crenate to serrate lobes. Sporangia in sinuses of shallow lobes, protected by reniform reflexed margins, in about 6 rather distant groups.

Rhizome rather slender to stout, far-creeping; paleae dark brown, not very glossy, hardly denticulate, to 4 mm long; stipites distributed along rhizome. Stipes rather stout, red-brown to purple-brown, 13-36 cm long, clad in long to very long hairs, mainly in groove, but some on stipe generally, paleate in lower portion. Rachis similar, flexuous, clad in long curved to flexuous red-brown hairs, mainly in the groove, as are secondary rachises and costae. Lamina ovate-deltoid to deltoid, 2-3 pinnate, 11-31 × 7-33 cm, olive green, glabrous above and below. Primary pinnae 1-4 pairs, to 16 × 13 cm, alternate, distant, deltoid, with 2-4 lateral pinnae and a terminal pinna. Secondary pinnae rather distant, to 9 × 2.5 cm. Pinnules up to 1.9 × 0.5 cm, shortly stalked, dimidiate, oblong to narrow oblong, lower margin entire, upper margin lobed, incisions usually reaching below the sorus, up to ^ of pinna depth. Sporangia in sinuses of shallow lobes, on upper and outer pinna margins, protected by reniform reflexed marginal indusium; up to 10 groups to each pinna.

Rhizomes far-creeping, scaly. Stipes and rachises stiffly hairy. Laminae ovate or broadly ovate, 15-35 × 10-25 cm, (2)-3-pinnate. Primary pinnae alternate, 2-5 on each side of rachis bearing secondary pinnae, and a terminal portion with 10-18 undivided primary pinnae on each side. Ultimate pinnules ± oblong or parallelogrammoid, often curved acroscopically at the apices, 6-25 × 3-8 mm; stalk attached at proximal corner; upper and outer margins irregularly lobed, lower and inner margins entire; upper surface glabrous, lower stiffly hairy, both surfaces dark green. Indusia ± reniform with prominent sinuses, glabrous, up to 14 per pinnule on upper and outer margins, sometimes extending to apical part of lower margin.
