Caudex short, erect; stipe to 50 cm long; basal scales to 15 × 1 mm, those above base gradually shorter, very narrow scales present on abaxial surface of both stipe and rachis, hairs 0.5 mm long also on rachis; lamina to 60 cm long consisting of 3-5 pairs of pinnae and a terminal portion c. 15 cm long; basal pinnae to 28 cm long (stalk 3-5 cm) bearing 3 or 4 pairs of pinnules with a deeply lobed apex like that of the lamina, basal basiscopic pinnule to 12 cm or more long, broadly lobed to 3-5 mm from its costa with 1 or 2 tertiary leaflets to 5 × 1.5 cm lobed halfway to the costule; first suprabasal pinnae with 1 pair of free pinnules; lobes of fertile pinnae and pinnules narrower than sterile; veins prominent on both surfaces, forming additional areoles below sinuses in less deeply lobed parts of pinnae: rather sparse hairs up to 1 mm long present on lower surfaces of costae and costules, also scattered on veins, thick hairs more than 0.5 mm long, scattered between veins on upper surface; sori in a row halfway between costules of lobes and margin, the lower ones on short veins in areoles, distal ones on free veins; indusia rather large, glabrous, shrivelling when old.
