Description:
Rhizome short-decumbent, up to 18 mm in diameter; rhizome scales up to 35 × 5 mm, brown to rust coloured, linear to narrowly lanceolate in outline, with scattered oblong glands, and irregularly set with long twisted filiform outgrowths. Fronds tufted, firmly herbaceous, 5–7 per plant, erect to arching, up to 1.6 m long. Stipe castaneous at the base, strawcoloured to greenish higher up, up to 87 × 0.8 cm, densely scaly at the base. Lamina ovate to broadly ovate in outline, up to 73 × 45 cm, up to 3-pinnate. Pinnae in up to 14 stalked pairs, basal pair longest and mostly basiscopically developed, glabrous or with few hairs or scales on the upper surface, sparsely to moderately set with scales and hairs on the lower surface; pinna-rhachis narrowly winged distally, abaxially initially with scales up to 6 × 1 mm. Pinnules oblong-acuminate in outline, rounded, lobed, to 1-pinnate. Costa adaxially shallowly grooved, narrowly winged, variously set with scales and hairs. Rhachis straw-coloured, with scales up to 8 × 1.2 mm, becoming glabrous with age.
