Rhizome short, erect, clad in dark brown linear-attenuate paleae; stipites tufted. Stipes (5)-30-60 cm. × c. 1-2 mm., dark brown and paleate near base, stiff, erect, smooth, shining and light brown above. Rhachis glabrate, with rather distant subopp. to alt. pinnae. Lamina (8)-30-90 cm. or more × (4)-30-60 cm. or more, ovate-deltoid, bright green, membr., 2-4-pinnate. Veins all free, mostly forked. Primary pinnae (5)-20-40 × 2-15 cm., subopp. to alt., shortly stalked, ovate-deltoid to ovate to lanceolate, acute to acuminate. Secondary pinnae up to 15 × 5 cm., subsessile, ovate to oblong, shallowly crenate-serrate on upper margin. Tertiary pinnae or segs 15-40 × 3-6 mm., crenately toothed, sessile, decurrent, oblong, obtuse. Fertile pinnae with segs up to 25 × 4 mm., lobed to entire. Sori cop., continuous along margins, often to tip and base.
Large terrestrial fern. Rhizome short, erect; apex covered with long narrow pale brown scales. Fronds dimorphic, tufted, 30–130 (–200) cm tall. Stipe (15–) 30–60 (–95) cm long, pale brown to chestnut-brown, with a few pale narrow basal scales, or scales absent. Lamina 2–4-pinnate-pinnatifid, ovate-deltoid, 25–60 cm long, 15–40 cm wide, pale green, usually ± herbaceous; rachis red-brown; ultimate segments linear, 10–15 (–30) mm long, decurrent, ± glabrous, but costules on undersurface somewhat hairy. Ultimate sterile segments c. 3 mm wide; margins toothed. Ultimate fertile segments (1–) 1.5 mm wide. Veins free, simple or once-or twice-forked. Sori ± continuous, but absent from bases and apices of ultimate segments; paraphyses absent. See also Green (1994: 568–569).
