Rhizome shortly creeping, 1.3-3.6 mm in diameter; rhizome scales reddish-brown, shining, narrowly elliptic-lanceolate to oblanceolate, apex rounded to pointed, 4-9.7 x 0.6-1.6 mm, margins practically entire towards the apex, finely toothed towards the base. Fronds simple, spaced apart (0.5-3 cm), thick, coriaceous. Stipe badly defined, up to 8 cm long, broadening gradually into the lamina, covered with hairs simular to those on the lamina but glabrous with age. Lamina narrowly elliptic-lanceolate to oblanceolate to narrowly elliptic, 7-45 x 0.3-3 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, apical or scattered over greater part of frond, hardly visible due to the dense tomentum. |
