Rhizome rather stout to slender, shortly creeping, us. with ascending branches; clad in pale brown to reddish ovate- to lanceolate-attenuate paleae, c. 2-5 mm. long; stipites clustered at tips of branches. Stipes slender to filiform, 2-15-(20) cm. long, stramineous to rather dark brown, shining, nude except at very base. Rhachis very slender, naked, narrowly winged in upper part. Lamina delicate, flaccid, pale green, narrow-lanceolate to ovate-lanceolate, pinnate to subbipinnate, 3-25 × 1-5 cm., often bearing sori in smallest state. Pinnae distant, alt. to subopp., lower shortly stalked, upper sessile and decurrent, 5 mm.-4 cm. × 4-15 mm. Shape various: ovate, pinnatifid, lobes crenately toothed to entire; ovate- to lanceolate-oblong, pinnatisect, lobes crenately toothed; ovate-oblong, again pinnate in lower, pinnatifid in upper portion, crenate-dentate, with secondary pinnae ovate-oblong up to 1 × 1cm., cuneately narrowed at base, lobes sts incised. Sori medial, 1-4 per lobe, 1-2 mm. diam., sts approximate to confluent. Indusium caducous, ovate, entire to ovate-oblong, shallowly toothed to subentire.

Rhizomes short, horizontal, scaly. Stipes 5-15 cm long, dark brown and scaly at base, straw-coloured and ± glabrous above. Laminae narrowly ovate, ovate or narrowly triangular, 10-30 × 6-14 cm, 2-3-pinnate at base, glabrous. Primary pinnae in 15-25 pairs, ovate to ± triangular, tapering at apices, the longest 3-8 × 1.5-4 cm. Secondary pinnae in 5-12 pairs, ovate to ± oblong, acute, to 2 × 1 cm, those on upper primary pinnae bluntly toothed, those on basal primary pinnae deeply incised or divided into tertiary pinnae. Sori rounded, protected by ovate indusia arching over sporangia.
