Rhizome 4-4.5 mm thick, shortly elongated, phyllopods 1-2 cm apart. Anatomy: vascular strands 9-11, ground tissue completely sclerified. Rhizome scales spreading, basifixed, 3-10 mm long, base often ciliate, acumen entire, brown; small scales often interspersed with the larger ones. Fronds monomorphic, sessile or indistinctly stalked, 26-111 by 2.5-7.3(-10) cm, index 7-20, base very gradually narrowed, widest above the middle, apex acuminate. Venation: veins distinct, veinlets much branched and strongly anastomosing, free veinlets excurrent and recurrent. Hydathodes distinct. Stellate hairs dimorphic, a dense mat, greyish brown, the straight upper rays appressed, narrowly boat-shaped to acicular. Sori apical, closely packed, 0.5 mm wide, containing c. 10 sporangia, many scattered over each areole, superficial, developing acropetally. Sporangia sessile or short-stalked, paraphyses not differentiated. Spores smooth.
