Lithophytic fern with erect or semi-erect fronds. Rhizome short-creeping, scaly. Stipe and rachis dark red-brown throughout, bearing abundant minute glandular hairs to 0.2 mm long, these becoming lost in older fronds; stipe 2–20 cm long, 0.2–2 mm diam. Lamina narrowly elliptic or narrowly ovate, pinnate, 4–50 cm long, 1.6–11 cm wide, bronze-green, with very sparse, glandular hairs on lower surface. Pinnae in 10–25 pairs, narrowly ovate; bases unequally cuneate, shortly stalked; margins slightly serrate in small specimens, deeply and slightly irregularly toothed in large specimens; apices acuminate; longest pinnae near middle, 8–70 mm long, 5–10 mm wide, gradually reducing upwards to an acuminate pinnatifid apical portion. Sori to 8 mm long, often congested and close to the costa. Perispores dark, reticulate, fenestrate; exospores 30.7–33.7 × 19.5–21.9 µm (means).
