Rhizome slender, c. 1/3-3/4 mm ø; scales honey-coloured, to 4 by 1/2 mm, to c. 16-seriate at the base. Petioles to 1.5 cm long, brownish and pale-angled. Lamina c. 12-25 by 2-3 cm, with up to c. 21 pinnules to a side; rachis adaxially shallowly grooved. Pinnules spreading or slightly ascending, mostly pale green when dry, the larger ones 12 by 5 to 15 by 7 mm, 2-3 times as long as wide, narrowed from the base to the narrowed-rounded or subacute apex; upper and lower margins almost straight, a distinct outer margin not developed. Upper margin crenately incised, the lobes rounded, often with irregular margin, mostly broader than long; incisions 5-6 per pinnule, 0.5-1 mm deep, rarely deeper, reaching to the level of the receptacle or beyond. Veins lax, once forked or simple. Sori uni-or binerval, roundish to oblong; indusium pale, entire, ½-2½ mm long, c. 0.4 mm wide, not reaching the margin by its width or more.
