Rhizome erect, short and stout, covered with brown scales with long-tapering tips. Fronds tufted, erect, 60–150 (rarely to 200) cm long, soft to firm-textured. Stipe usually more than half the frond length, slender, stiff, chestnut-brown, shiny. Lamina 2–4-pinnate, triangular to ovate-triangular, light green to yellow-green, glabrous or with hairs along lower surface of midveins and rachises; rachises red-brown. Primary pinnae distant, triangular, slightly asymmetric, lower pinnae projecting out from main plane of lamina; secondary pinnae variable, bases decurrent, apices frequently linear. Pinnules oblong to narrowly oblong, sessile, bases decurrent, margins crenately toothed or almost entire; veins relatively distant, simple or forked, free. Sori continuous or disjunct along lateral margins, often to tips and down decurrent bases.
