ture subcoriaceous ; surfaces naked ; main veins distinct nearly or quite to 

 ttie edge: areolae fine, hidden. Sori in I row on each side of the coslae, ± 

 medial, superficial. — Young plants with the fronds simple and yet often 

 fructiferous. 



War. aiigiiistatiiin: Pinnae + cuneate at the base, the lower ones 

 + stalked, the higher sessile, narrowly or hardly adnate to the rachis. 



War. obtu§(iiill: Like var. angustatum, but the pinnae + blunt, 

 very thick in texture.

Rhizome creeping, the scales subulate, short-ciliate, with the base peltate, 

 rounded or sometimes hastate. Stipes '/2 — 1^ c.M. long, naked. Fronds 

 polymorphous, simple, 1 — 3-fid or pinnate with 1 — 4 pinnae on each side 

 below the terminal one. Simple fronds '/2 — ^ c.M. long, oblong or lanceo- 

 late, obtuse at both ends. The 2 — 5-fid fronds are intermediate forms be- 

 tween the simple and pinnate ones. Pinnate fronds to 20 c.M. long, nearly 

 as broad. Pinnae lanceolate, acute or acuminate, entire or undulate, sessile, 

 adnate or the lower short-stalked, articulate to the rachis. Texture coria- 

 ceous ; surfaces naked ; main veins distinct nearly to the edge ; veins immers- 

 ed. Sori in 1 row on each side of the costa in the simple fronds and in 

 1 — 3 rows on each side in the pinnate forms, slightly immersed.

Rhizome very thick, the scales dense, long, linear, crisped, brown. Fronds 

 sessile, arranged in a circle, 60 — 120 c.M. long, the lower part 10—20 c.M. 

 broad, the base dilated, cordate, the edge narrowed, lobed, passing gradually 

 into the upper part of the frond, which is 50 — 45 c.M, broad and cut down 

 nearly to the costa throughout into entire, erecto-patent segments 2'/j — 4 c.M.
