Fronds close or subclustered; stipe stramineous, base swollen into shuttle form and concealed in scales, with two vascular bundles, upward usually glabrous, pubescent, or glandular; lamina ovate-oblong to pentagonal-ovate, truncate at base, 3-pinnate to finely 4-pinnate-pinnatifid, anadromous, basal pinnae largest, upper ones gradually reduced, herbaceous or papery, both surfaces, rachises, and costules frequently covered with acicular and/or glandular hairs, rarely glabrous. Veins free, pinnate, branches simple or forked, ending at margin. Sori rounded, located at middle of veinlets. Indusia persistent, large, reniform or horseshoe-shaped, membranous, ± covered with acicular or glandular hairs, rarely glabrous. Spores ellipsoidal, bearing prominent, inflated folds with papillate elements. x= 41, 40.
