Fronds tufted; stipe stramineous, brown, or castaneous, scaly throughout; stipe scales brown or blackish brown, narrowly to ovate-lanceolate, never clathrate or iridescent (as those in Ctenitis). Lamina lanceolate to ovate, once pinnate with deeply lobed pinnae to amply 3-pinnate; basal pinnae oblong, lanceolate, or triangular, usually not or slightly longer than next pair, basal basiscopic lobe or pinnule mostly not enlarged; distal pinnae adnate to rachis and ± decurrent at their bases; veins free; lamina papery, adaxial surface with thick multicellular hairs; rachises and costae grooved and densely covered with ctenitoid hairs or sometimes with hair-scales (structure intermediate between hairs and scales) on adaxial surface, various scale types present or not on abaxial surface. Sori terminal or dorsal on veins, medial to submarginal, one line on either side of costules; indusia present, persistent; spores ellipsoid to spheroidal, perispore echinate or coarsely tuberculate. x = 41.
