Caudex arborescent. Stipe and rachis densely covered with short, ad- 

 pressed hairs. Fronds lanceolate-oblong, to 1^2 M. long, to 60 c.M. broad. 

 Pinnae lanceolate, stalked, erecto-patent, + 10 — 12 '/2 c.M. broad, the stalks 

 1 — I'/i c.M. long. Pinnulae short-stalked, linear-lanceolate, + 2 — 3 c.M. 

 broad at the base, the apex acuminate. Tertiary divisions sessile or suhsessile, 

 the lowest anterior largest, linear-oblong, 1 '/i — 2 c.M. long, to + 5 m.M. 

 broad, the apex blunt, toothed, the edge cut down nearly or quite to the 

 costa into oblong, blunt, inciso-dentate ultimate segments, the lowest anterior 

 segments the largest. Texture herbaceous; upper surface nearly naked, the 

 under one densely hairy like the secondary and tertiary rachises. Sori small, 

 near the ultimate sinuses; annulus long, the extremities separated by a whorl 

 of radiating, slightly thickened cells with the stalk of the sporangium placed 

 in the centre.

Fronds 3-pinnate to 4-pinnatifid. Pinnae to ± 45 c.M. long and 15 c.M. 

 broad, stalked. Pinnulae lanceolate, acuminate, alternate, + 5 c.M. apart, 

 short-stalked, + 2 c.M. broad at the base. Ultimate divisions oblong-ovate, 

 short-stalked, the lower ones rather distant, + 5 m.M. apart, cuneate at 

 the base, pinnatifid from Va'^ay down to quite to the costa, the upper ones 

 more close and less deeply lobed, or even entire. Texture herbaceous but 

 firm; rachis naked, orange-coloured, slightly scabrous. Sori intramarginal, 

 lateral on the lobes, 1 — 6 to a pinnula, transversally oblong; indusium 

 broadly ovate. Veins conspicuous, pinnate in the lobes.

Fronds ample, subdeltoid, 4-pinnatifid ; rachis stramineous, naked. Pin- 

 nae lanceolate, 15 — 55 c.M. long. Pinnulae close, short-stalked, lanceolate, 

 1 — 1'/2 c.M. broad. Tertiary divisions oblong-rhomboidal, 2 '/a — 5 m.M. broad, 

 sessile, the base cuneate, more or less cut away on lower side, the edge 

 inciso-pinuatifid. Texture moderately firm; both surfaces naked; veins sub- 

 flahellale. Sori at the tops of the ultimate sinuses; indusium cup-shaped, 

 naked. — Perhaps this may be the description of a single pinna regarded
