Rhizome long-creeping, rarely shortcreeping, sometimes mat-forming, especially when dwarfed; paleae ovate-lanceolate, acute or apiculate, 1.5-3.0 × 0.45-0.75 mm. Stipes marked, (0.1-)0.5-2.0 cm long; stipe hairs usually dark red-brown, rarely paler, abundant, 0.5-3.0 mm long. Lamina linearoblanceolate to linear-spathulate, acute to obtuse, (0.6-)2.0-7.0(-13.0) × (0.2-) 0.28-0.50 (-1.0) cm; lamina hairs dark red-brown, rarely paler, 0.5-3.0 mm long, absent to common on lamina apart from in sori, where always abundant; texture thinly to thickly coriaceous; veins visible to invisible, endings not darkened; midrib raised somewhat on lower surface, concolorous with or darker than lamina. Sori subglobose to oblong, in upper part of frond, sometimes terminal, 1-12 pairs, 1.0-4.5 × 0.5-2.0 mm, usually confluent when mature; soral vein somewhat longer than sorus, shorter than basiscopic vein, neither reaching margin. Sporangia (230-)271.7-338.7(-400) mcm long; indurated cells of annulus (10-) 11.6-15.6 (-21). Spores (30-)38.8-49.6(-60) mcm diam.
