Pinnae in 10–35 pairs, from broadly ovate or ovate at base to ±oblong or elliptic at mid-frond, sometimes with an enlarged basal acroscopic lobe; bases unequally cuneate, shortly stalked; margins sharply and irregularly incised; apices obtuse; longest pinnae near middle, 8–35 mm long, 5–17 mm wide, gradually reducing upwards to an attenuate apical portion. Sori to 10 mm long. Perispores dark with fimbriate wings and smooth or veined lacunae; exospores 34.7–38.7 × 24.8–27.4 µm (means).
