604 71. POLTPODnJM. § 1. EUPOLTPODIUM. d. PINNATAK. 



Rhizome wide-creeping, woody, the scales dense, brown, small, narrowed 

 gradually from a rounded, peltate base towards the acuminate point. Stipes 

 scattered, brownish, naked, glossy, wiry, slender, ±10 c.M. long. Fronds 

 + lanceolate, 15 — 20 c.M. long, a*/^ — 5'/2 c.M. broad, narrowed towards 

 both ends, or the base nearly as broad as the central part of the frond, the 

 edge cut down nearly to the costa. Pinnae spreading, 3 — 5 m.M. broad, the 

 apex blunt, the edge slightly, not regularly crenate, the base dilated, the sinu- 

 ses as broad as the lobes. Texture coriaceous; surfaces naked; costa promi- 

 nent below; costulae distinct, + wavy; veins oblique, forked, free or united 

 near the base by the arched anterior veinlets, which are nearly parallel to 

 the costulae and bear a very short soriferous branch directed towards 

 the edge. Sori round, small, superficial, ± 6 — 8 on each side, nearer the 

 costulae than the edge, 1 between each pair of veins. — The description is 

 taken from a specimen gathered by Hallier (No. 3312) and determined by 

 Christ (Ann. Btz., XX, 120).

Rhizome wide-creeping, the scales dense, large, lanceolate, brown, mem- 

 branaceous. Stipes brown, naked, 5 — 8 c.M. long. Fronds oblanceolate, 20 — 25 

 c.M. long, 7 — 9 c.M. broad at the middle, cut down nearly or quite to the 

 rachis. Pinnae close, entire, linear, S'/j — 4 c.M. long, + 4 — 5 m.M. broad 

 above the dilated deltoid base; lower pinnae reduced so as to form a repand 

 wing to the rachis. Texture subcoriaceous ; surfaces naked; veins hidden. 

 Sori round, medial, superficial, 6 — 9 on each side of the costa in the fully 

 developed central pinnae.

 Rhizome shorl-creeping, the scales small, brown, ovate-lanceolate. Stipes 



wiry, naked, 2Vs — 5 c.M. long. Fronds lanceolate, simply pinnate, 15 — 20 

 c.M. long, to 2*/2 c.M. broad. Pinnae adnate, lanceolate or oblique-cuneate, 

 I'/j — 2 '/a m.M. broad, entire or obscurely crenate on the upper edge. Tex- 

 ture coriaceous; surfaces naked; veins hidden. Sori solitary, immersed, sub- 

 terminal on the pinnae, the edges of the latter folded round them.
