Trunk to 7 Vj M. high. Fronds ample, tripinnate. Racbis of pinnae pale- 

 brown, slightly furfuraceous and rough with raised points. Pinnae oblong- 

 lanceolate, ± 60 c.M. long, 15 — 20 c.M. broad. Pinnulae sessile, lanceolate- 

 ligulate, + 2 72 c.M. broad, cut down to the racbis into close, blunt, distinctly 

 crenate, tertiary segments + 5 m.M. broad. Texture thin, but firm; surfaces 

 naked, the under one with a few bullate scales on the midribs of the tertiary 

 segments; veins 12 — 14-jugate, close, fine, distinct, forked, the lowest sometimes 

 bifurcate. Sori placed close to the costae, with a distinct space between each, 

 sometimes 12 — 15 to a segment, absent from the upper ^/g of the segments.

Stipes densely covered with lighl-brown scales 2—5 c.M. long, muri- 

 cate like the more or less densely scaly rachises; the spines short, often 

 black-tipped. Fronds large, to 2^2 M. long, ovate-lanceolate, 3-pinnate. Pinnae 

 to 45 c.M. long or longer, ±15 c.M. broad, stalked. Pinnulae sessile, ± 

 1^2 c.M. broad, linear-lanceolate, acuminate. Tertiaiy segments sessile, free 

 or slightly joined at the base, ± 272 m.M. broad, entire, blunt, slightly 

 convex. Texture coriaceous; upper surface naked or slightly hairy on the 

 costae; under surface densely covered with pale-brown-yellowisb hairs and 

 tomentose, ragged scales on the costae and tertiary rachises; veins 8 — 12 on 

 each side, mostly forked. Sori close to the central ribs of the ultimate 

 segments, hidden between the scales.
