Rhizome ascending, rather elongate, clothed with minute, brown 

 scales. Stipes approximate, + 6 cm. long, broadly winged quite to the 

 base. Fronds + 20 cm. long, + 3 cm. broad, pinnatifid, the apex 

 elongate, subdentate. Lobes numerous, pectinate, separated by rounded 

 sinuses, spreading, the central ones sublinear-ligulate, + 1 '/,, cm. long, 

 + 3 mm. broad, subacute, the lower ones abbreviated. Texture herbac- 

 eous; colour pale-green, opaque; surfaces naked; costa hairy; costulae 

 flexuose ; veins simple, obUque, + 6 on each side of the costulae. Sori 

 minute, ± 1 — 5 on each side of the costulae, medial, immersed, round, 

 the lower ones oblong, approaching the main costa.

Rhizome short-creeping, densely scaly at the apex, the scales elongate- 

 lanceolate, bluntish, Uvid-fuscous, cancellate, provided with black-purplish, 

 often forked setae especially near the margin. Stipes fasciculate, erect, 

 2 — 5 cm. long, subterete or slightly chanelled above, fuscous-green, densely 

 clothed with rufo-fuscous, forked or stellate, spreading setae. Fronds 60 

 cm. or more long, 4 — 6 cm. broad, nutant, revolute when dry, linear, 

 narrowed towards both ends, decurrent upon the stipe, deeply pinnatifid. 

 Segments numerous, alternate, suberecto-patent, connected by a wing ± 

 2 mm. broad, nearly linear or narrowed gradually from the base to the 

 apex, the largest ones + 2% cm. long, 5 — 672 i^™- broad at the base, 

 the base often nearly equal-sided (the upper base somewhat broader 

 than the lower), the edge entire, flat, the apex acute or bluntish; upper 

 pinnae gradually abbreviated but hardly narrower, lower ones much 

 abbreviated and dilated, connected by a narrow wing. Texture papyraceo- 

 herbaceous; surfaces clothed with tufted, rufo-fuscous setae but more or 

 less densely so with forked ones at the margin ; upper surface livid-green, 

 lower paler; costa elastic, slightly prominent beneath; costulae and veins 

 immersed but visible when seen towards the light; veins simple, the 

 lowest anterior ones forked, the lowest posterior ones originating from the 

 costa. Sori 8 — 11 on each side, rather terminal, not occupying the lower 

 and upper veins of the segments, elliptic, slightly immersed, surrounded 

 by simple or forked, rufo-fuscous setae.
