somewhat contracted, pinnatilid to '/4-way down to the costa, the lohes 

 blunt, sparingly repand, horizontal or nearly so. Texture firm; upper 

 surface dark-olivaceous when dry, naked ; under surface paler, squamulose 

 on the costae, costulae and veins, the scales minute, scattered, buUate, 

 ovate, acuminate, brown or pale-brown ; main veins pinnate in the teeth 

 or lobes; veins to 4 on a side, simple, the lowest sometimes forked. Sori 

 medial, to 3 (rarely 4) on a side.

Stipes to 1 m. long. Fronds to + 3 m. long, 3-pmnatiM ; main 

 rachis subfuscous when dry, scabrous with numerous, minute, black-brown- 

 tipped, longitudinally oblong projections which are probably the persistent 

 bases of fallen hairs and scales, beneath deciduously furfuraceo-tomentose, 

 above hairy and scaly, the tomentum pale-ochraceous, the hairs moderately 

 long, dense, pale-ochraceous, longitudinally subadpressed, intermixed with 

 spreading, fragile, articulated bristles which are mostly red-brown towards 

 the base (and whether or not flattened, non-articulate, pale-yellow and 

 shortly ciliolate in the upper part), the scales long, narrowly subulate- 

 lanceolate, pale-yellow, ciliolate with short, suberect, acute, red-brown 

 hairs. Pinnae ± 15 on a side, short-stalked, to 50 cm. or more long, 

 acuminate, the rachis and costae smooth or nearly so, beneath deciduously 

 pale-furfuraceous, above copiously clothed with moderately long, subad- 

 pressed, pale-ochraceous hairs. Pinnulae close or approximate, sessile, 

 horizontal or nearly so, deeply pinnatipartite, acuminate, the acumen 

 bluntish, serrate or crenate towards the apex, coarsely toothed in the 

 lower part; central pinnulae largest, about 11 cm. long, 2^U_ cm. broad 

 at the truncate base. Segments approximate, subhorizontal, hnear-oblong, 

 straight or subfalcate, to I'l^ cm. long and 3 mm. broad, dilated at the 

 base, blunt or bluntish, crenate, the crenations simple or 2 — 3-crenate 

 again, at least the lower deciduously ciliated, the ciliae spreading, articul- 

 ated, solitary on the apice of the veins; lowest segments not rarely free, 

 horizontal and not dilated at the base. Texture . herbaceous ; surfaces 

 naked ; upper surfaces provided with shallow impressions corresponding 

 with the receptacles; costulae and veins provided above with a few 

 scattered, acute, pale-yellow setae; costulae scaly beneath, the scales
