﻿604 71. POLYPODIUM. § 1. EUPOLYPODIUM. d. PINNATAE. 



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, 16 — 20 c.M. long, 2^2 — S'/j 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 veinlels, 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, ^% — 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 short-creeping, the scales small, brown, ovate-lanceolate. Stipes 



wiry, naked, V/^ — 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- 2V2 m-M. broad, entire or obscurely crenate on the upper edge. Tex- 

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

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