 or more long, 30 — 35 cm. broad, the rachis densely pubescent. Pinnae 

 ± 20 on a side below the long, pinnatiM terminal one, the 2 — 3 lower 

 pair reduced, the lowest auricle-like, the largest short-stalked, nearly 

 horizontal, + 2 cm. broad, acuminate, truncate at the base, cut + '/a" 

 way down to the costa into rounded, subfalcate, entire lobes. Surfaces 

 pilose and glandular; 2 — 3 lower veins anastomosing. Sori medial;

Fronds + 75 cm. long and 30 cm. broad. Pinnae straight, the largest 

 short-stalked, + 18 cm. long, 2 cm. broad at the base, narrowed gradually 

 towards the acuminate apes, cut + '/j-way down to the costa into 

 truncate lobes; terminal pinna similar to the lateral ones; 1 or more 

 lowest pinnae suddenly reduced to mere auricles. Texture coriaceous; 

 surfaces sparingly setose, costae densely so ; veins simple, + 7 on a 

 side, mostly the 2 lowest anastomosing. Sori nearer the costulae than 

 the edge; indusium inconspicuous; sporangia intermixed with numerous 

 glanduloso-capitate paraphyses. — Differs fom D. truncata 0. Ktze by the 

 very minute indusium, the presence of paraphyses, and the spores are
