Stems ca. 2 mm diam. Leaves partially dimorphic (sporangia limited to proximal pair of pinnae), 17–85 × 7–35 cm, sterile leaves (excluding erect fertile pinnae) 17–60 cm. Petiole straw-colored to chestnut brown, 1/2–2/3 length of leaf, 1–1.4 mm wide, hirsute to glabrous. Blade deltate, 3-pinnate, leathery. Pinnae 10–18 pairs, alternate to subopposite, segments oblanceolate, base cuneate, margins minutely denticulate, apex obtuse, pilose with stiff white hairs. Fertile pinnae usually taller than sterile blades. Spores with ridges ± parallel, distant. 2n = 76, 114, 152.
