Veins visible on both surfaces, pinnate in segments, 4 or 5(-7) pairs, simple, sometimes forked in basal segments. Lamina herbaceous when dried, brown-green, rachis, costae, and veins on both surfaces with sparse longer multicellular hairs. Sori oblong or shortly linear, sometimes J-shaped in distal part of pinna, 1.5-2 mm, 3-5 pairs per segment; indusia similar to sori, brownish, slightly erose at margin, persistent. Spores bilateral, perispore surface with rugate, rugate-saccate, or papillate processes. 2n = 160*.
