Rhizome stout, far-creeping, 4-10 mm. diam., densely clad in dark brown narrow subulate-acuminate paleae; stipites distributed. Stipes stout, 15-50-(90) cm. × 3-10 mm., subsucculent, densely paleate at base, glab. above, dark to olive green or blackish in lower portion, lighter above. Rhachis stout, glab., light brown, with distant opp. to subopp. sessile pinnae. Lamina 25-100 × 10-50 cm., deltoid to ovate-lanceolate, membr. to subcoriac., ± glaucous, 2-(3)-pinnate; veins cop., anastomosing to nearly all free. Largest primary pinnae 8-40 × 5-20 cm., ovate-lanceolate, rather distant, opp. or subopp., sessile. Secondary pinnae rather distant, opp., (confluent in distal region of pinna, distantly pinnate .in proximal region) 2-7 cm. × 10-15 mm. Sterile pinnules ovate to oblong, broadly crenately lobed to subentire; fertile pinnules narrower, triangular, entire or obscurely lobed, attached by widened base, often subfalcate. Sori us. cop., extended along margins but not reaching tips of segs, without true indusium. Occ. fronds of much larger dimensions are met with.
Rhizome subterranean, c. 5 mm in diameter, set with a dense felt of brown multicellular hairs. Fronds erect to arching with pinnae held horizontally, 1-2 (3) m tall; stipe castaneous, labrous, up to 0.6 m long; lamina pinnatifid to-pinnatifid, broadly lanceolate to ovate-deltate in outline, acute, up to 0.4 x 0.19 m, basal pinna segments auriculate and developed very close to rhachis; ultimate lobes oblong, acute to obtuse, adnate, entire to sinuate, glaucous when fresh; rhachis reddish brown to pale brown nearer apex, terete, glabrous. Sori linear or rarely lunulate, up to 1 mm broad at maturity, borne along margins of ultimate lobes (lobes frequently with sterile apices); indusium membranous, entire.
Stipe and rachis chestnut-brown at base, but mostly yellow-brown, glabrous except for basal scales, glossy; stipe 15–120 cm long, 5–10 mm diam. Lamina 30–c. 200 cm long, 15–c. 100 cm wide, ovate, 3-or 4-pinnate at base. Primary pinnae in opposite pairs; longest 13–60 cm long, 7–35 cm wide, arising at narrow angles, sessile. Secondary pinnae opposite, arising at wide angles; longest 4–20 cm long, 2–9 cm wide, with basal pair sometimes reduced to stipules. Tertiary pinnae opposite; longest 10–45 mm long, 6–15 mm wide, sometimes divided into quaternary pinnae. Ultimate pinnules adnate to midribs; margins entire or crenate; apices obtuse. Spores pale, tuberculate. [See also Green (1994: 586).]
Rhizome widely creeping, up to 5 mm in diam., sparsely scaled. Fronds spaced, arching, up to 2 m long. Stipe glabrous, up to 600 mm long, up to 5 mm in diam. Lamina broadly lanceolate, pinnatifid to 2-pinnatifid, up to 1.3 x 0.8 m. Pinnae near opposite, sessile; proximal pinnae segments auriculate and developed close to rachis; ultimate lobes oblong, entire to sinuate. Sori linear, along margins of ultimate lobes. Indusium entire.
Rhizomatous perennial, rhizome widely creeping. Fronds arching, to 3 m long, stipe glabrous, lamina pinnatifid to 2-pinnatifid, broadly lanceolate, proximal pinnae segments auriculate and developed close to the rachis, ultimate lobes oblong, entire to sinuate. Sori linear along margins of ultimate lobes, indusium entire.
Rhizome creeping, set with brown hairs. Veins anastomosing freely. Fronds glabrous and glaucous. Indusium formed from reflexed margin of lamina. Lamina 2-or 3-pinnatifid, up to 0.4 x 0.19 m. Sori marginal, continuous, with paraphyses.
