Rhizome short, ascending; stipites tufted. Stipes stout, up to 15 cm. long. Rhachis stout, smooth, nude, with about 20 alt. to subopp. pinnae. Lamina about ovate-oblong, 20-90 × 5-20 cm., coriac., yellowish green, subacuminate, 3-(4)-pinnate. Primary pinnae up to 10 × 3·5 cm., stalked, ovate-lanceolate, subacute (barren pinnae with broader, less dissected pinnules). Secondary pinnae stalked, c. 3 × 1 cm., about ovate-oblong to lanceolate. Tertiary pinnae c. 1 cm. long, pinnatifid to pinnatisect; segs linear to narrow-oblong, subacute, slightly expanded in region of sori. Sori near tips of segs, solitary, submarginal, oblong, c. 2 mm. long, us. plentiful.

Rhizome short, erect, bearing redbrown, linear attenuate scales. Stipes up to 15 cm long, green above, brown below, sparingly covered in small linear scales with long filiform apices (Fig. 24 O-P). Laminae oblong to elliptic, 15-90 × 10-25 cm, yellow-green, coriaceous, 3- to 4-pinnate. Raches green, almost lacking scales, prominently grooved. Pinnae ovate to narrowly ovate, acuminate, stalked, up to 12 × 5 cm. Secondary pinnae linear to lanceolate, up to 15 × 2 mm, often pinnatifid. Ultimate segments linear, subacute, slightly expanded in the region of the sori. Sori near tips of ultimate segments, solitary, broad, submarginal, c.2mm long. Spores (46)51-63(71) mcm long, (32)34-44(50) mcm wide (3 populations), perispore prominently winged, granular, but not conspicuously ridged (Fig. 30C-D).
