cM. long, I'/a— 2 c.M. bfoad, linear-oblong, acuminate, inciso-serrale at the 

 apex. Tertiary divisions numerous, linear-oblong, subfalcate, obtuse, sessile,

Trunk to 7Vj M. high. Fronds ample, tripinnate. Rachis 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 '/j c.M. broad, cut down to the rachis into close, blunt, distinctly 

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

 naked, the under one with a few buUate 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 */, 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 272 M. long, ovate-lanceolate, 3-pinnate. Pinnae 

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

 172 c-M. broad, linear-lanceolate, acuminate. Tertiary 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-yellowish 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 botwoon - the scales. | Secondary rachises densely woolly- -^
