150 — 



the lowest anterior branch midway between the midrib and 

 edge of the pinnae. Sori uniserial, round, medial. 



• Forests at the base of the Cerro Pelado, near Villa 

 Rica, Allied to P. recur vat urn, Kaulf., from which it 

 may be known at a glance by its distinct pinnate veins. 



Notochlaena Balansae, Baker, n. sp. Rhizome 

 stout, short- creeping, densely clothed with linear and at the 

 "growing point with subulate bright brown scales. Stipes 

 contiguous, wiry, brown, l 1 ^— 3 in. long, matted with rusty 

 brown tomentum, as is the rachis and lower surface of the 

 lamina. Frond lanceolate, regularly bipinnate from the base 

 nearly up to the tip, 6—8 in. long, 1— l 1 ^ in. broad, firm 

 in texture, green and nearly naked above, matted all over 

 with tomentum beneath. Pinnae subsessile, linear, ascen- 

 ding, ^a — 8 / 4 in. long, x / 4 — 1 / 3 in. broad, cut down all through 

 to the midrib into spreading entire contiguous adnate linear- 

 oblong obtuse pinnules. Veins hidden. §ori continuous all 

 round the entire flat edge of the pinnules. 



Escarped banks of the Rio Paraguay, at Assumption. 

 General habit of Cheilantes mieromera, 



Gymnogramme (Ceropteris) longipes, Bake, 

 n. sp. Caudex erect. Stipes tufted, bright castaneous- 

 above a foot long, with only a few small spreading lanceo, 

 late scales near the base. Lamina lanceolate, 2 — 3-pinnate, 

 1—2 ft. long, 2—4 in, broad, moderately firm in texture, 

 green and glabrous on the upper surface, covered all over 

 on the under side with bright yellow powder. Pinnae 

 nearly sessile, deltoid, the lower ones remote and diminished, 

 the central ones 2-3 in. long, caudate, cut down below 

 to the rachis into linear- oblong toothed or at the base com- 

 pound pinnules. Veins close, distinct. Sori reaching from 

 the midrib to the edge. 



Assumption, in damp soil; and 334 a var. con color 

 of the same species, entirely destitute of the yellow meal. 

 This would be a fine plant to introduce into cultivation. 

 It comes midway between trifoliata and the ochracea 

 variety of calomelanos. 



Acrostichum (Elaphoglossum) tenerum, Baker, 

 n. sp. Rhizome short- creeping. Scales scarcely any. Stipe 

 of_ barren frond, slender, stramineous, 2—5 in. long. La- 

 mina linear, membranous, glabrous, bright green on both 

 sides, 6—9 in. long, 1 in. broad at the middle, irregularly 

 crenulate, narrowed gradually from the middle to both ends- 

 Veins moderately close, distinct, simple or forked, rather 

 ascending, produced from the midrib to the edge. Fertile
