Stipe up to 55 cm long, straw-coloured to almost black, glabrous or set with a few scales towards the base, shiny. Sterile lamina 45-63 cm × 2-3 cm, oblong-lanceolate in outline with terminal pinnae equal in shape to the lateral pinnae, lower pinnae not reduced; pinnae narrowly lanceolate in outline, apex tapering to a point, margins finely toothed, base asymmetric broadly wedge-shaped to truncate, short petiole, widely spaced to overlapping, glabrous above, small scales on costae and veins below. Fertile lamina smaller or same size as sterile lamina; pinnae widely spaced, thin, narrowly linear. Sori linear, cover almost the whole length of the fertile pinnae; indusium continuous, lacerate, c. 1.5 mm wide. |
