Rhizome moderately long creeping and occasionally branching, 1-3 mm in diameter; rhizome scales dark brown to black with paler base and margins, ovate to ovate elliptic, margin with cilia especially at the base, base auriculate with overlapping lobes, apex acute. Fronds simple, space 0.5-1 cm apart, sub-coriaceous to coriaceous. Sterile fronds: 20-35 cm, stipe up to 15 cm long, stramineous to dark brown, grooved, bearing scales similar to rhizome scales but larger and paler. Sterile lamina linear- elliptic to linear in outline, apex sharply pointed or tapering to a point, base tapering and prolonged down the axis, 10-24 × 0.6-1.8 cm, glabrous above, paler and with small brown scales 0.2-1mm below, margins rolled outwards towards the abaxial side. Fertile fronds: equaling or slightly shorter than sterile fronds but with a slightly longer stipe, lamina linear-elliptic to linear-obovate, apex with a short narrow point, base narrowly wedge-shaped and prolonged down the axis.
