Fronds very variable in size, usually from 6 in. to 20 in. long, but luxuriant specimens sometimes attain 30 in., 2–5 in. broad, ovate-deltoid or ovate-lanceolate or linear-oblong, acuminate, membranous, dark olive-green or olive-brown, erect or pendulous, 3–4-pinnatifid. Stipes 2–6 in. long, not winged, more or less densely clothed (as are the primary and secondary rhachides and costæ) with reddish-brown jointed hairs; rhachis winged above, wingless below. Primary pinnæ 1–3 in. long, close or rather distant, spreading or erecto-patent, rhomboidal-lanceolate or -oblong, acuminate; secondary deeply pinnatifid or 2-pinnatifid. Ultimate segments linear, obtuse, flat, quite entire. Sori numerous, terminal on the lateral segments on both sides of the pinæ. Indusium rather small, orbicular or ovate-orbicular, 2-valved to the base; valves usually toothed.—''A. Cunn. Precur. n. 235; Raoul, Choix, 39; Hook. Sp. Fil. i. 110; Hook. f. Ft. Nov.

Rhizomes long, wiry, creeping, often much branched and interlaced, more or less clothed with yellow-brown woolly hairs. Fronds very variable in size and shape, usually 3–9 in. long, but sometimes reduced to less than 1 in., at other times attaining a length of 12 in., the smaller specimens generally ovate and erect, the longer ovate-lanceolate to lanceolate or linear-oblong and pendulous, pale shining-green or
