Rhizome c. 3 mm thick, long-creeping, phyllopods 4-8 cm apart, buds halfway along the internodes. Anatomy: vascular strands 9-12, sclerenchyma sheath distinct, sclerenchyma strands 15-20, in a ring within the vascular cylinder. Rhizome scales appressed, peltate, 3-7 by 1-1.5 mm, base entire, acumen long-ciliate, central region brown to blackish. Fronds dimorphic, stalked. Fertile fronds with stalks to 26 cm long, 1-2.5 as long as the lamina, lamina 5-10 by (1-)3-5 cm, index 2-3(-7), base narrowed, widest at or below the middle, apex rounded to acuminate. Sterile fronds with stalks (2-)5-17(-30) cm, lamina index 1.5-2(-3), otherwise similar to fertile fronds. Venation: veins distinct, veinlets much branched and anastomosing, free veinlets excurrent and recurrent. Hydathodes distinct. Stellate hairs monomorphic, appressed, forming a dense mat, dirty whitish, rays short, boat-shaped. Sori small, closely packed, superficial, developing more or less simultaneously. Sporangia stalked, paraphyses not differentiated. Spores coarsely tuberculate.
