Stipes slender, black-purple, hairy, provided beneath with few scat- 

 tered, broadly ovate, thin scales. Fronds + 30 cm. long, 5— SVj cm. 

 broad, the rachis hairy and scaly, the scales red-brown. Pinnae cut down 

 nearly to the costa, the largest + 2'/2 cm. long by '/^ cm. broad, the 

 lower hardly abbreviated. Lobes oblong, obtuse, entire. Texture coriac- 

 eous; costulae sparingly scaly, the scales red-brown; veins + 8. Sori 

 medial on the veins; indusium reniform. — The proper place of this
