Fertile fronds up to 1.2 cm; stipe stramineous or green-stramineous when dry, 25-45 cm, 2-3 mm in diam., upward glabrous; lamina broadly lanceolate, 35-70 × 15-20 cm at middle, base often slightly narrowed; lateral pinnae 4-15 pairs, alternate, sessile or shortly stalked, slightly ascending, oblong-lanceolate, apex acuminate; basal 1-3 pairs of pinnae often reduced, ovate or narrowly ovate; middle pinnae subcontiguous, 8-15 × 1.5-3 cm, base broadly cuneate or subtruncate, margin entire; apical pinnae larger than lateral pinnae, similar, base asymmetrical; veins anastomosing with 2 or 3 rows of oblique long hexagonal areoles. Lamina green or yellow-green when dry, pale on abaxial surface. Sori thick, linear, 5(-8) mm, often from near costa to near or below middle of pinna; indusia brown, sausagelike, opening acroscopically or ruptured on back side when mature, persistent. 2n = 164.
