| Description: |
Rhizome creeping, c. 2 mm in diameter; rhizome scales reddish-brown, shining, lanceolate, c. 6 mm long, margins practically entire towards the apex, finely toothed towards the base. Fronds simple, spaced apart, thick, coriaceous. Stipe badly defined, up to 1 cm long, broadening gradually into the lamina, covered with hairs simular to those on the lamina. Lamina narrowly lanceolate to narrowly elliptic, up to 30 × 3 cm, apex sharply pointed to rounded, base tapering, margin entire, midrib slightly prominent on both surfaces; lamina covered with a dense coat of light brown, stellate hairs with slender arms of c. 1 mm long, upper surface soon becoming (sub)glabrous, stipe only much later. Sori c. 0.5 mm, scattered over greater part of frond, hardly visible due to the dense tomentum. |
| Notes: | Can be confused with Pyrrosia schimperiana which has fronds that are covered with more whitish hairs with short, flat arms. |
