Stipes naked, greyish.- Fronds large. Lower pinnae lo 30 c.M. long, 

 7 — 10 c.M. broad, deeply pinnatifid into oblong-lanceolate, acuminate, entire 

 or distantly crenale lobes. Texture subcoriaceous ; rachis, veins and mai-gins 

 slightly hairy on both sides; veins of the lobes slightly pinnate, and mostly 

 forming costal arches. Sori small, copious, principally in irregular rows near 

 the costulae.

Rhizome erect, scaly at the crown. Stipes stout, 40—60 c.M. long, scaly 

 towards the base. Fronds oblong-deltoid, 60—90 c.M. long, the upper part, 

 deeply pinnatifid vrith lanceolate, pinnatifid lobes. Pinnae in ± 6 pairs; the 

 lowest largest, equilateral, 15—25 |c.M. long, 5—9 c.M. broad, cut more than 

 '/j-way down to the costa into narrow, oblong, crenated segments to ± S'/j 

 c.M. long, ± 5 — 8 m.M. broad. Texture subcoriaceous, opaque ; surfaces nak- 

 ed or the upper one furnished with scattered, small, jointed, transparent 

 scales; venation pinnate in the lobes, forming aieolae near the costae only. 

 Sori medial or nearly so, in 2 rows on each side of the costa along the wing 

 and in a single row on each side of the costulae; indusium fugacious.

 or sinuated. Texture coriaceous: surfaces naked. Sori usually in 1 row on 

 each side, nearer the edge than the costulae ; indusium early fugacious, (often
