Rhizome long-creeping, 4–6 mm diameter; rhizome scales ovate- to linear-lanceolate in outline, margin entire or irregularly toothed with occasional hair-like processes, 4 mm long, yellow-brown to brown, dull to lustrous; phyllopodia 1 cm, blackish. Fronds dimorphic, spaced c. 1cm apart, coriaceous. Sterile fronds 15–32 cm long; stipe ± 1/2 the sterile frond length, straw coloured, 1 mm diameter, with lanceolate to ovate scattered scales, 1.5 mm, yellow-brown with processes; lamina simple, elliptic in outline, apex rounded to pointed, base wedge-shaped to broadly so, 4–18 x 1.6–3.2 cm; veins ± 1 mm apart, at 70° angle to costa; hydathodes absent; costa scales scattered, nearly ovate with irregular processes, yellow-brown, lanceolate, ± 1 mm; laminar surfaces with scattered minute dot-like scales exuding a sticky resin or rarely minute peltate scales to glabrous on the undersurface, upper surface less so; young unrolling fronds sticky. Fertile fronds slightly shorter to than the sterile; stipe 2/3 the fertile frond length; lamina lanceolate-oblong to elliptic in outline, 11–12 x 2.7 cm, apex pointed, base rounded; porangia covering the whole underside of the fertile lamina; intersporangial scales absent. |
