Rhizome 0.8–2 mm diam., at first with scattered appressed dark brown rounded prominently ciliate scales. Fronds of 1–8 tiers of branches, 10–22 (–42) cm long, rarely more than 6 cm wide, at first completely covered with red-brown scales, glabrescent; lower tiers often branched 1–3 times. Stipes clustered along rhizome, 4–42 cm long, initially bearing dark brown scales with long white matted ciliate margins, glabrescent, smooth; rachis and undersurfaces of upper branches with persistent, red-brown scales with paler ciliate margins, completely obscuring undersurface of pinnules. Pinnules with brown hairs along costae on upper side, with dense reddish brown scales at first completely obscuring the undersurface; ultimate segments 0.7–1 mm long, 0.6–1.1 mm wide, round, obtuse, strongly convex above, pouched below; undersurface white.
