Rhizome short, the scales brown. Stipes tufted, rigid, castaneous, + r» 

 c.M. long, densely clothed with dark-coloured, spreading hairs. Fronds 15 — 20 

 c.M. long, + 1 '/i — 2 c.M. hroad, lanceolate, the apex and base narrowed, the 

 point bluntish. Texture membranaceous, thin; colour green, paler beneath; 

 midrib prominent; main veins zigzag, pinnate; vein tips thickened; both sur- 

 faces villose. Sori terminal on the 3 — 4 lower veins so as to form several 

 irregular rows on each side of the midrib.

Rhizome short, creeping, clothed with broad, lanceolate, acuminate, stra- 

 mineous scales. Stipes slender, 2 — 4 c.M. long, densely provided with stra- 

 mineous, spreading hairs. Fronds lanceolate, 10 — 15 c.M. long, 1 — I'/j c.M. 

 broad, narrowed towards both ends, the margin sinuate especially in the lower 

 part. Texture coriaceous; surfaces naked, but the edges ciliate with a few 

 short hairs; veins free, immersed, hidden, pinnate or to + 4 X forked. Sori 

 round, large, superficial, in 1 — 3 irregular rows, or altogether scattered.

Rhizome creeping, slender, the scales narrow, brown. Fronds scattered, 

 sessile or short-stalked (stalks under 272 c.M. long), resembling the stipe of 

 a rush, subterete, 15 — 25 c.M. long, less than 2^/2 mM. broad and thick, 

 with 5 furrows, of which the 2 lowest are the deepest. Texture corriaceous; 

 surfaces naked; no veins. Sori oblong, vertical, alternate, placed in the deep- 

 est furrows.

 pale-brown. Stipes short, naked, approximate. Fronds simple, 27^ — 6V2 c.M. 

 long, ± 3V2 — 4 m.M. broad, + entire, obtuse, narrowed at the base. Tex- 

 ture firm ; surfaces naked ; veins distant, erecto-patent, forked, not reaching the
