the main rachis, and provided witli minute, bullate scales, not furfur- 

 aceous. Pinnulae 4 — 10 cm. long, 1 — 2 cm. broad at the base, acuminate, 

 cut down nearly or quite to the costa, pinnate at the base. Segments 

 falcate, obtuse or obtusely apiculate, entire or crenate, to 2^!^ mm. broad, 

 the lower varying from adnate to shortly petiolulate and rounded at the 

 base. Texture coriaceous; costae (tertiary rachises) hairy above, scaly 

 beneath, the lower scales lanceolate-subulate, the others shorter, rather 

 lanceolate, bullate at the base; costulae (at least the lower) bullato- 

 squamulose especially in the lower part; veins 8 — 10 on a side in the 

 largest segments, naked, mostly once or twice forked; Sori subcostular, 

 crowded, not occupying the higher veins; indusium distinct but not very 

 large, dark-brown.

Stipes, clothed with pale-castaneous scales. Fronds 90—150 cm. long, 

 narrowed towards the base; main rachis smooth, castaneous, glabrescent 

 beneath, clothed above with red-brown-purple hairs intermixed with long, 

 subfiliform paleae. Pinnae subsessile, to 35 cm. long and 12 cm. broad, 

 acuminate, the rachis red-brown-hairy above, clothed beneath with minute 

 bullate scales intermixed with a few scattered, deciduous, linear ones; 

 lower pinnae very small, 1'/^ long. Pinnulae often sessile, lanceolate, 

 pinnate in the lower part, acute, the costa red-brown-hairy above, buUate- 

 squamulose beneath. Segments 8 mm. long, 2 — 2 '/j m.m. broad, the lower 

 free, adnate, straight or subfalcate, obtuse, entire or crenulate to obscurely 

 serrulate, with the central ribs clothed beneath with small, bullate-ovate 

 scales especially in the lower part; veins 8 ± on aside, the lower once or 

 twice forked. Texture papyraceous; surfaces naked; under surface 

 paler than the upper. Sori costular, often subtended by a minute scale 

 (rudimentary indusium).
