Ehizonie wide-creeping, slender, wiry, branched, blackish or dark- 

 brown when dry, the scales ovate or lanceolate-subulate, reddish-brown, 

 acuminate, minutely and irregularly denticulate, peltate at the base. 

 ■ Stipes remote, 2-seriate, articulated above the base, of the barren fronds 

 2 — 3 mm., of the fertile fronds to 12 mm. long. Barren fronds broadly 

 oblong or ovate, 1 — 1 '/j cm. long, ^/^ — 1 V4 cm. broad, blunt or rounded 

 at the tip, entire, the base broadly cuneate, rotundate-truncate or subcordate 

 and suddenly decurrent so as to form a narrow wing reaching nearly or 

 quite to the base of the stipe. Texture coriaceous; surfaces purveyed 

 with a few scattered, adpressed, deciduous peltate hairs ; costa evanishing 

 in the upper part ; areolae subhexagonal, oblique, with few excurrent 

 free veinlets. Fertile fronds linear, semiterete, I'/j — 4'/2 cm. long, 2'/^— 

 3 nam. broad, deeply and broadly 2-sulcate beneath, the apex bluntish, 

 the sides parallel, entire, the base narrowly cuneate, long-decurrent. Sori 

 in the grooves, continuous, nearer the costa than the margin, filling up 

 the whole under surface except the cuneate base, flanked by rows of 

 long-stalked, pale peltate hairs, the capsules of each sorus separated by 

 a longitudinal row of densely crowded, simple or variously branched, pale 

 paraphyses so as to form 2 parallel series of capsules to a sorus.
