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

 the edge; areolae fine, hidden. Sori in 1 row on each side of the costae, + 

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

 fructiferous. 



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

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



War. obtuisiuil: Like var. angustatum, but the pinnae + blunt, 

 very thick in texture.

(219ft) P. proteus, Copeh, Philipp. Journ., I, Suppl., 164, tab. XXV. 



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

 rounded or sometimes hastate. Stipes '/a — 17 c.M. long, naked. Fronds 

 polymorphous, simple, 2 — 3-fid or pinnate with 1 — 4 pinnae on each side 

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

 late, obtuse at both ends. The 2 — 3-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 30—45 c.M. broad and cut down 

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