Rhizomes erect, suberect, or prostrate; rhizome scales reddish brown, linear, 1.5-3 mm. Stipe dark stramineous, 40-50 cm; stipe scales appressed, reddish brown, lanceolate or ovate-lanceolate, 2-3 mm; scales on rachis and costae similar but smaller. Lamina 3-pinnate to 4-pinnatifid, ovate-triangular, 40-60 × 30-40 cm; pinnae 12-14 pairs; basal pinnae largest, triangular, 18-22 × 12-16 cm; pinnules 10-12 pairs; basal basiscopic pinnules of basal pinnae longest, 8-10 × 2.5-3.5 cm; bases of upper pinnae or lobes not obviously decurrent, without veinlets arising from rachis. Lamina herbaceous; veins free, distinct, no veinlets arising from costae. Sori medial or submedial, often near costae, indusiate; indusia usually fugacious, glabrous. Perispore coarsely echinate.
More
Caudex massive; stipe to at least 120 cm long (Hance), its base covered with light brown thin scales 20-40 mm long, the scales gradually shorter upwards for 5-10 cm, then a subabrupt change to copious appressed overlapping clathrate scales; lamina as long as stipe; basal pinnae of lectotype of Nephrodium rhodolepis 45 cm long, their largest pinnules bearing 4 or 5 pairs of tertiary leaflets, the largest very deeply lobed; scales on smaller axes of frond to 1 mm wide, consisting almost entirely of isodiametric cells or at least of cells not much longer than wide; indusia thin, rather irregular in shape, bearing cylindric glands and sometimes also hairs of several cells.
