Lamina pinnate with a free conform terminal pinna, roughly lanceolate in outline. Sterile pinnae petiolate, glabrous, linear to oblong-lanceolate in outline, margin entire to wavy, apex rounded to bluntly pointed, base unequally wedge-shaped, usually directed forward at about 45° from the rhachis and facing upwards; midrib prominent on lower surface; venation visible on upper surface with areoles. Fertile pinnae similar in size and shape to sterile pinnae, or sometimes slightly smaller, undersurface entirely covered with sori.
