Rhizome only known from very short pieces, c. 3.5 mm ø; scales reddish brown, to c. 1 mm (or more?) long, to ± 4-seriate at base, with long, acicular, uni-or pauciseriate apex. Petioles stout, rather lustrous, medium brown, crushed but apparently abaxially upward obtusely bi-angular, c. 60 cm long. Lamina probably 30 cm or more long (no complete leaf seen), pinnate + quadripinnatifid or subbipinnate + tripinnatifid at the base, probably deltoid; primary pinnae at least 4 to a side, the lower ones remote. Primary rachis stramineous to medium brown, abaxially apparently bi-angular. Largest primary pinnae oblong, with a petiolule of a few mm, c. 18 by 5 cm, with c. 12-15 major secondary pinnae to a side, these somewhat ascending; axes of higher than the first order abaxially stramineous, rounded, narrowly green-margined to base, only the basal ones unmargined at the extreme base. Larger secondary pinnae c. 8-12 by 3-6 cm, elongate-triangular, with c. 10-15 segments to a side, these chartaceous, obliquely ascending, not close, lanceolate to linear, the largest 1.5-3 cm by 4-5 mm, deeply pinnatifid at base, at the acute apex like the smaller segments dentato-lobate. Ultimate lobes lanceolate-ligulate, the larger ones up to 4 by 1.75 mm, subacute, often somewhat falcately ascending, asymmetric, with a bulge on the anterior margin where the sorus is situated, smaller lobes triangular, with subterminal sorus. Apical lobes of segments not soriferous. Veins abaxially evident at base but higher up evanescing, simple, forked in larger lobes. Sori uninerval; indusium brownish, pouch-shaped, narrowed at base, often with irregular free edge, 0.3-0.5 mm long and broad. Spores brownish, subellipsoidal, smooth, c. 35 by 26 μ.
