Rhizome erect to short-creeping; paleae pale red-brown, lanceolate to narrowly lanceolate, acute to broadly acute, 1.5-4.3 × 0.4-1.2 mm. Stipe indistinct, winged almost to base; stipe hairs whitish to pale red-brown, abundant, 0.4-1.6 mm long. Lamina linear-elliptic to oblanceolate, acute to obtuse, (2.3-)4.6-9.6(-13.9) × (0.35-)0.50-0.88(-1.20) cm, margins rarely somewhat crenulate; lamina hairs whitish to pale red-brown, common to abundant everywhere, 0.5-1.2 mm long in sori, usually somewhat shorter on margin (0.2-0.6 mm long); texture thinly coriaceous; veins visible or not, sometimes raised on upper or lower surface in dried material; midrib raised on lower surface, concolorous with or darker than lamina. Sori oblong, oblique, in middle part of frond, 8-22 pairs, 1.5-5.0 × 1.0-1.5 mm. Soral vein not or slightly prolonged beyond sorus; basiscopic vein approaching margin, soral vein rarely almost equalling basiscopic vein. Sporangia (150-) 160.8-193.6(-240) mcm long; indurated cells of annulus (9-)9.9-12.3(-14). Spores (20-)23.5-27.3(-33) mcm diam.
