Rhizome 6-8 mm thick, not elongated, phyllopods contiguous. Anatomy: vascular strands c. 12, ground tissue completely sclerified. Rhizome scales spreading, basifixed, 4.7-7.8 mm long, entire, brown. Fronds monomorphic, sessile or indistinctly to 5 cm stalked, lamina 33-100 by 3.2-12.5 cm, index 8-14, base very gradually narrowed, widest above the middle, apex abruptly acuminate to apiculate. Venation: veins distinct, veinlets much branched and strongly anastomosing, free veinlets many, excurrent and recurrent. Hydathodes distinct. Stellate hairs dimorphic, a dense thin mat, light greyish brown, the straight upper rays dark brown, acicular, appressed with one central, elongated (to 2.5 mm), erect ray always present.
