5. N. Brackenridgii, Baker ; rhizome thick, clothed with lanceolate ferruginous 

 scales ; st. 3-4 in. 1., chesnut-brown, glossy, nearly naked ; fr. 4-5 in. 1., oblong-

 aceous ; upper surface dark-green, nearly naked ; lower and rachis densely 

 clothed with small, linear, dark chesnut-brown scales. N. sinuata, Brack, p. 12 

 (non Kaulf.). 



Hab. Peru, Brackenrldge. 



6. N. incequalis, Kze. ; rhizome stout, the scales long, dense, fibrillose, bright- 

 ferruginous ; st. 3-6 in. 1., firm, erect, naked, stout, ebeneous ; fr. 4-6 in. 1., 2-3 

 in. br., lanceolate or subdeltoid, tripinnatifid ; upper pinnce, lanceolate, lower 

 deltoid, with blunt lanceolate pinnatifid pinnl. ; texture thick ; both surfaces 

 densely coated with ferruginous woolly tomentum ; the rachis nearly naked. 

 Hk.Sp. 5. p. 118. 



Hab. Macalisberg, near Natal, Burlce; Angola, Welwitzsch, 147, 197. A larger plant 

 than the last, almost as woolly, but the tomentum brown. 



7. N. Aschenhorniana, Kze. ; st. tufted, 2-3 in. 1., wiry, ebeneous, densely scaly ; 

 fr. 8-12 in. 1., 2-3 in. br., oblong-lanceolate, tripinnatifid ; pinnce lanceolate, 1-1^ 

 in. 1., in. br., cut down to the rachis into linear-oblong crenate or pinnatifid 

 pinnl. ; texture subcoriaceous ; upper surface pale-green and slightly hispid, lower 

 densely matted with linear, ciliated, bright-ferruginous scales, beneath which it 

 is subfarinose ; sori black, the edge not inflexed. Hk. Sp. 5. p. 117. t. 287* B. 



Hab. Mexico. This and the next three are very near to one another. 



8. N. squamosa, Baker ; st. tufted, 1-4 in. 1., densely clothed with ovate-acu- 

 minate pale-brown scales ; fr. 3-4 in. 1., 1 in. or more br., ovate-lanceolate, 

 bipinnate ; pinnce opposite, the lowest | in. 1., % in. br., ovate, blunt, cut down to 

 the rachis below into several linear-oblong pinnl. ; texture thick, subcoriaceous ; 

 rachis and under surface densely covered with ovate- or lanceolate-acuminate 

 ciliated ferruginous scales ; sori brownish, the edge subscariose. Cheil. Hk. Sp. 2. 

 p. 82. H. & G. t. 151. 



Hab. Mexico and Guatemala to Peru and the Argentine territory. Probably this is 

 N. peruviana, Desv., and if so, that name is the oldest. Mettenius distinguishes from 

 this C. brachypus, Kze. (Nothochlcena, J. Sm.), by its shorter stem, and the presence of 

 long flaccid hairs as well as scales on the under surface. 



9. N. Marantce, R. Br. ; rhizome woody, the scales dense, fibrillose, bright-fer- 

 ruginous ; st. strong, wiry, 3-6 in. 1., more or less matted ; fr. 4-12 in. 1., 1^-3 

 in. br., oblong-lanceolate, bipinnate ; pinnce lanceolate, cut down to the rachis 

 into close, oblong, entire pinnl. 1 lin. br. ; texture thick, coriaceous ; upper surface 

 pale-green, naked, lower and rachis densely coated with lanceolate, bright-ferru- 

 ginous scales. Hk. Sp. 5. p. 120. 



Hab. Himalayas (up to 15,000 ft.), Syria, and Tauria, to Ardeche and Portugal ; 

 Barbary States, Abyssinia, Azores, Madeira, Canaries, Cape Verde Isles. 



10. N. JEcHoniana, Kunze ; rhizome woody, the scales lanceolate, dense, bright- 

 ferruginous ; st. 3-6 in. 1., strong, erect, scaly ; fr. 6-12 in. 1., 2-3 in. br., bi- 

 tripinnatifid ; upper pinnce close, the lower ones subdistant, deltoid ; pinnl. close, 

 lanceolate, pinnatifid or pinnate, with short, oblong segm. ; tenure thick, cori- 

 aceous ; upper surface pale-green, lower and rachis densely clothed with bright- 

 ferruginous scales. Hk. Sp. 5. p. 116. 



Hab. Cape Colony and Natal. Usually more divided than the last, but very doubt- 

 fully distinct.
