Laminae elliptic to narrowly elliptic, 30-200 × 10-25 cm, pinnate. Primary pinnae in > 40 pairs, overlapping in middle of frond, more widely spaced at base, the longest 5-15 × 0.8-1.6 cm, with undersurfaces covered in scales with fimbriate margins, falcate with a basal acroscopic lobe, tapering to acute apices; margins irregularly crenate or serrate especially near apex. Sori round, in single rows near margins of pinnae, protected by reniform indusia.
