Rhizome short creeping, clothed in reddish brown clathrate concolorous linear scales up to 7 mm long, bearing a few filiform projections at the margins. Fronds tufted stiff and coriaceous. Stipes (5-)8-15(-24) cm long, scaly, dark brown but becoming green on the upper surface towards the lamina. Lamina (7-)9-20(-30) cm long, 4-9 cm wide, oblong-lanceolate, the lowermost five pairs of pinnae equal in length or only slightly reduced towards the basal pair, bipinnate; rachis sparsely scaly and dark brown on the lower 1/2 or 2/3 of the abaxial surface, green elsewhere. Pinnae 7-15 pairs, up to 5 cm long, 2.5 cm wide, elongate-trapeziform, glabrous and shiny bright green on the upper surface and sparsely fibrillose and matt paler green on the under surface, with 1-5 pinnules below a lobed apex. Pinnules rounded cuneate or rounded obtrullate with irregularly shallowly dentate apices which are often slightly lobed. Sori indusiate, 5-12 mm long, covering almost completely the undersurface of the pinnules and pinnae lobes. Spores monolete, 38-50 µ long (range of means 42-47 µ); perispore with thin anastomising wing up to 12µ wide. Chromosome number n = 144; reproduction sexual.
