Terrestrial; rhizome long-creeping, 3–5 mm in diameter, with dense overlapping gland-tipped broadly triangular scales 1–2≈1 mm. Fronds spaced 0.5–3.5 cm apart, erect; stipe brown, 18–55 cm long, base with lanceolate scales 4–5≈0.4–1 mm, upper part with dense fine ctenitoid / catenate hairs 1–2 mm long, glabrescent; lamina dark green above, yellowish green below, thin to sub-coriaceous, deltoid-pentagonal in outline, with wide basal pinna pair strongly curving upwards, 18–36≈15–32 cm, 3–4-pinnatifid; rachis not winged, grooved almost to apex; pinnae up to ± 12 on each side of the rachis, apex gradually decrescent, pinnae closely aligned, not overlapping; basal pinna to 26≈13 cm, with well-developed basiscopic pinnule; second pair shorter and less pinnatifid, central pinnae to 12≈4 cm, 1-pinnate except for the basal pinnules which are 2-pinnatifid; ultimate segments of central pinnae slightly falcate, 7 mm wide, crenate to entire, apex obtuse; margin of lamina framed by single line of achlorophyllous cells; veins and veinlets forked, not reaching margin; indument on abaxial surface sparse, denser on venation, of ctenitoid hairs 0.4–1.3 mm long, on adaxial surface with only a few trichomes 1–2 mm long near forks of veins. Sori sub-median, near tip of acroscopic lateral veinlet, 1–1.5 mm in diameter; indusium kidney-shaped with lateral notch, 0.8 mm in diameter, from notch lines of square cells fan out, almost every second cell tipped by glandular hair ± 4 cells long; spores monolete, oval, 0.04 mm long, exospore with crest of few, blunt spines.
