Rhizome compact, to 10 mm diameter; rhizome scales linear-lanceolate, dark reddish-brown to black, 3–5 mm long, concolorous, lustrous, with rigid (rarely weak and irregular) hair-like teeth that may be deciduous with age; phyllopodia distinct, 6–10 mm long, dark brown. Sterile fronds clumped, 18–85 cm long; stipe 1/8–1/3 of frond length, stramineous to brown, 1–1.5 mm diameter, densely clothed with spreading, linear-lanceolate, ciliate, orange-tan scales, often with dark red-brown to black margins and/or teeth, 2–5 mm long; blade narrowly elliptic to oblanceolate,12–75 cm long, 2–4 cm wide, chartaceous, apex acuminate to subcaudate, base cuneate; costa prominent; veins obscured by scales, free, simple or once-forked, ± 1 mm apart, at ± 70° angle to costa; hydathodes absent; blade scales scattered to imbricate, linear-lanceolate, ± 3 mm long, long hair-toothed, concolorous orange-tan abaxially, whitish adaxially, more thinly adaxially and those with narrower scale body and longer cilia surfaces, costal scales with concolorous or dark hairs. Fertile fronds (uncommon) shorter and narrower than the sterile; stipe 1/2 of frond length; blade linear-lanceolate, 10–24 cm long, 1–2 cm wide, apex rounded to acuminate, base cuneate to truncate or rounded, orange-tan scales present beneath on costa only, densely covering upper surface; intersporangial scales absent.
