Rhizome short-creeping, tliicli, woody, densely clothed with long, 

 subulate, hair-pointed, black-brown, glossy scales. Stipes approximate, 

 + 30 — 55 cm. long, fuscous, very minutely hairy, at length naked, 

 angular and grooved when dry, scaly towards the base. Fronds + 30 — 45 

 cm. long, pinnate, the rachis deciduously and very minutely puberulous. 

 Pinnae + 4 on each side below the terminal one, opposite, remote ^ 

 terminal pinna simple and lanceolate, or trifid at the base with lanceolate 

 segments ; higher pinnae ascending, sometimes suberect, simple, lanceolate, 

 subfalcate, ± 10 cm. long, + 3 — S'/j cm. broad, sessile or short-stalked, 

 acuminate, cuneate or more or less rotundate-cuneate at the base; 1 — 2 

 lower pinnae stalked, to + 20 cm. long, forked at the base on the lower 

 side with 1 — 2 lateral segments, rounded, truncate or cordate at the base, 

 the terminal segment + 5 — 6 cm. broad, similar to the higher pinnae, 

 the lateral segments similar but smaller, free or connected, sessile or 

 stalked; stalks very minutely puberulous, as are the costae and main 

 veins above; edges entire or irregularly repand to sinuate. Texture 

 herbaceous; surfaces naked; main veins slender, reaching nearly the
