Terrestrial, epiphytic or lithophytic; rhizome erect, to 6 cm high; rhizome scales shiny dark brown, ovate, 8–13≈2–3 mm, acuminate, pale centre, pale fimbriate margins. Fronds tufted; stipe with narrow adaxial and lateral grooves, 8–29 cm long, with pale brown scales 8–15≈1.5–3 mm, irregularly fimbriate, denser on sterile fronds, less dense on fertile fronds; lamina dark green adaxially, pale greyish green below, coriaceous or thin, narrowly ovate or elliptic, 20–40≈8–18 cm, 1-pinnate; rachis abaxially with sparse fimbriate scales, denser around stalks of pinnae; pinnae 3–12 on each side of the rachis, irregularly rhomboid-falcate, 4.7–8.5≈2–2.5 cm, base cuneate on basiscopic side with acroscopic side truncate and auriculate, apex up-turned, acuminate, blunt, margin finely denticulate or serrate particularly on acroscopic lobe; apical pinna triangular with unilateral basal lobe; veins anastomosing regularly, forming 2–3 ± parallel zones of areoles, traversed by pinnate veins, on periphery free veinlets reach serrate points but not margin. Sori ± regularly positioned on acroscopic free branch in areole, soral lines approximately parallel to longitudinal axis of pinna, 0.3–2 mm in diameter; indusium an ephemeral dark rust-red funnel-forming peltate stalk 0.25 mm, opening into highly dissected umbrella shape ± 1.8 mm in diameter; on dehiscing, peltate funnel-stalk detaches like plug from receptacle. Spores monolete, oval, 0.03≈0.025 mm. Fig. 9.
