Fronds approximate; stipes ca. 20 cm, stramineous; laminae ca. 100 × 30 cm, bases narrowed, apices acuminate; pinnae ca. 30 pairs, proximal ca. 10 pairs abruptly shortened with lowest 1 pair ca. 5 mm; middle pinnae linear-lanceolate, ca. 20 × 1.5-2 cm, bases truncate, lobed 1/3-1/2 toward costae, apices long acuminate; segments 30-40 pairs on middle pinnae, oblong, ca. 3 × 3 mm, subacute or obtuse at apices; veinlets 6-8 pairs per segment, proximal 1.5 pairs anastomosing, next pair running to sinus membrane. Laminae papery, shortly pubescent and with several acicular hairs on both surfaces along costae and veins, abaxially also with sessile spherical yellow glands. Sori orbicular, medial; indusia glandular and shortly hairy. Sporangia bearing several hairs and sessile spherical glands on capsules, and similar glands on stalks.
