Fronds clustered; stipes 8-25 cm, stramineous, with sparse scales on bases, throughout with dense grayish white multicellular long acicular hairs when young, hairs gradually fallen when old; laminae lanceolate, 15-25 × 4-8 cm, not narrowed to bases, 1-pinnate, pinnatifid-acuminate at apices; pinnae 8-10 pairs, alternate, spreading, proximal pair slightly shortened, proximal 3 or 4 pairs free, sessile, distal ones ± adnate to rachises; middle pinnae ovate-oblong, 2-3.5 × ca. 1.5 cm, bases broader, rounded-truncate, symmetrical, margins subentire or slightly undulate, apices shortly acute. Veins evident, 2 or 3 pairs of veinlets between veinlets, proximal pair joining, sometimes an excurrent veinlet arising at this union and connected to an acroscopic veinlet of second pair, forming a triangular plus a rhomboid areole. Laminae yellow-green, herbaceous or papery, abaxial surface on intercostal areas shortly hairy, adaxially setaceous along margins and apices; along abaxial side of rachises with dense multicellular long acicular hairs, shortly hairy along abaxial sides of costae and veins, setaceous adaxially. Sori linear, attached along veinlets, exindusiate, remaining clustered and with erect short hairs at attached places of sori after fallen; sori with 2 or 3 short hairs.
