| Description: |
Rhizome up to 1.2 cm. in diameter, erect; rhizome-scales up to 1 cm. long, dark brown, linear-lanceolate in outline, margin entire. Stipe 63 cm long, 8 mm in diameter, light brown to castaneous, with sparse stout erect or recurved spines up to 3 mm. long, glabrous except for numerous scales similar to those on the rhizome about the base. Fronds tufted, arching, herbaceous. Lamina almost as broad as long, up to 1 × 0.9 m., ovate to broadly ovate in outline, 3–4-pinnatifid. Lowest pinnae up to 56 cm. long and developed basiscopically; pinnae narrowly triangular in outline, petiolate; the costae and costules of larger pinnae sparsely set with stout spines on the undersurface and with a spine at the junction of main veins on the upper surface; ultimate lobes c. 4 mm. broad, narrowly oblong to linear in outline, apex round to pointed, with the sterile margins of the fertile and sterile segments toothed, glabrous on both surfaces; veins free; rhachis and secondary rhachises castaneous, with sparse stout erect spines up to 2 mm. long. Sori linear, marginal in basal half of the segments; indusium entire, membranous. |
