Frond erect, membranous, not proliferous. Stipe matt-brown, up to 17 cm long, with very few short hairs when young, glabrous with age and with a few scales similar to those of the rhizome-scales near the base. Lamina pinnate, oblong to narrowly oblong-acuminate, basal pinnae not reduced, pinnae in 17-20 pairs, petiolate, rhombic, dimidiate for almost 1/2 the length of the costa, broadly to narrowly acute, very unequally cuneate at the base, serrate to mostly doubly serrate on the acroscopic margin and upper part of the basiscopic margin up to 5.5 x 1.5 cm, glabrous on both surfaces. Rhachis matt-brown with occasional multicellular hairs. Sori up to 7 mm long, very narrowly oblong, set at about 45§ to the costa about midway between the costa and margin; indusium narrowly oblong, membranous, entire.
