Rhizome 1.2-3 mm thick, long-creeping, phyllopods 2-5 cm apart, buds halfway along the internodes. Anatomy: vascular strands 6-8, sclerenchyma sheath distinct, sclerenchyma strands absent. Rhizome scales spreading, peltate, 2.6-4.4 by 0.4-0.8 mm, base entire to ciliate, acumen ciliate, light brown; rounded to ovate scales without acumen regularly present. Fronds moderately dimorphic, stalked. Fertile fronds with stalks to 1.5-5 cm long, 0.2-0.5 as long as the lamina, lamina 7-19 by 0.7-1.2 cm, index 8-20, base narrowed, widest at or below the middle, apex obtuse to acute. Sterile fronds with stalks 0.5-3 cm, 0.1-0.5 as long as the lamina, lamina 3-13 by 1-1.8 cm, index 3-8, otherwise similar to fertile fronds. Venation: veins distinct, veinlets forked and anastomosing. Hydathodes absent. Stellate hairs dimorphic, loose to appressed, forming a dense mat, whitish brown, the straight rays boat-shaped to acicular. Sori all over the lamina, very closely packed, superficial, developing more or less simultaneously, soral area appearing acrostichoid when old. Sporangia stalked, paraphyses not differentiated. Spores with irregular ridges and protuberances.
