 spreading, about 1 cm. broad, the apex acuminate, crenate-dentate, the 

 edge cut about '/i-"^ay down to the costa into subfalcate, blunt or 

 obUquely subtruncate, entire lobes about 8 mm. broad. Texture coriaceous; 

 surfaces naked; costae hairy above; costae and costulae sparingly fimbriato- 

 squamulose beneath; veins to + 4 — 5 on a side, mostly simple, not or 

 hardly prominent. Sori on the 1 — 3 lower veins, inframedial, at length 

 confluent so as to form a broad brown band on each side of, and close 

 to, the costae; capsules intermixed with long, pale, hyaline hairs.

Trunk ± 1 m. high. Stipes + 45 cm. long, purple-black like the 

 lower part of the main rachis, clothed especially towards the base with 

 densely crowded, narrowly lanceolate, firm, stramineous, minutely black- 

 ciliated scales. Fronds ovate, + 75 cm. long, hardly 60 cm. broad, the 

 main rachis scaly in the lower part, pale in the upper part which is 

 velutinous above and glabrescent beneath. Pinnae subsessile, the central 

 the largest, + 30 cm. long, + 10 cm. broad, acuminate, with the rachis 

 narrowly winged. Pinnulae subsessile, approximate, oblong or somewhat 

 elongated, ± 1 '/j cm. broad, obtuse, truncate at the base, the edge cut 

 at best to '/■2"'^3'.V down to the costa. Lobes approximate, falcate, broadly 

 oblong, entire. Texture papyraceous; surfaces naked; costae sparingly 

 pilose above, nearly naked beneath; costulae clothed beneath with deciduous, 

 minute, whitish, bullate scales; veins 4 — 6 on a side, often simple. Sori

 much longer than the sporangia.
