Fertile frond, abaxial view. rachises alate; blades 1 pinnate-pinnatifid, linear-lan- ceolate; pinnae glabrous, nearly symmetric, gradually reduced towards the base of the blade, with mucronate apices and margins; veins free; sori linear; and indusia with undulate margins. It is similar to Asplenium pteropus Kaulf. , which differs by lanceolate blades (vs linear-lanceolate), alae interrupted at junctions of rachises and pinnae (vs alae continuous), and pinnae entire with serrate margins (vs pinnatifid, the segments with mucronate apices).
