remote, petiolate, 5-6 in. 1., 5-6 lines \v., spreading, linear-lanceolate, subffexuose, 

 finely acuminate, subirregularly pinnatifid about half-way to the costa; 

 lobes ovate, entire ; veins pinnated ; veinlets simple or rarely forked ; sori rather 

 copious, occupying the lower portion of the lobes half-way between the costule 

 and the margin ; recept. very hairy, very slightly elevated. ~Hk. Sp. 1. p. 38. 

 Hab. Organ Mountains, Brazil. 



8. A. procera, Klf. ; st. aculeated and paleaceous below with very large and 

 exceedingly glossy, dark brown scales; fr. submembranaceous, bipinnate, 

 glabrous, pinnatifid at the apex ; prim, pinnce 1 ft. 1. or more, the rachis winged 

 above ; pinnl. 2-3 in. 1., from a truncated sessile base 4-5 lines w., oblong- 

 acuminate or obtuse, pinnatifid half-way down to the costa ; costce and costules 

 beneath bullato-squamulose ; lobes short subrotundate, often acute, mostly entire ; 

 veins simple ; sori small on all the lobes, between the costule and the margin.

Hab. Trop. America, frequent. A. Arbuscula, Presl, is a variety with white bullate 

 scales on the ribs of the under surface of the pinnules. 



9. A. Schiedeana, Pr. ; "fr. ample, submembranaceous, bipinnato-pinnatifid ; 

 pinnce and pinnl. alternate, remote, subsessile, the latter lanceolate, unequal at 

 the base, shortly acuminate, deeply pinnatifid ; segm. oblong, falcate, sinuato- 

 crenate, subdilatate and obtuse at the apex ; sori arranged between the costule 

 and the margin, small, somewhat apart ; costce and costules sparingly fusco- 

 paleaceous ; part, and univ. rachises sulcated, fusco-tomentose above, beneath 

 aculeolate ; st. aculeate ; caud. arboreous." Kze. in Linn, 13. p. 149. Hk. Sp.

 finely pubescent below ; pinnce oblong-lanceolate, lf-2 ft. 1. ; pinnl. ligulate,

 both sides densely pilose, the lower with copious pale broad minute scales on the 

 ribs ; veins 7-9-jugate, forked ; sori large, medial. Crypt. Bras. t. 44. A. Gard-

Hab. Columbia and Brazil. A. hypolampra, Kze., Kuhn, Linn. 36,158, seems from 

 the description to be a large variety, with sharply toothed segments, the lower subpin- 

 natifid, with subpinnate veinlets. 



12. A. aspera, Br. ; st. and rachis strongly aculeated, main (sometimes strongly 

 aculeated too) and partial rachis above strigillose, slightly scaly beneath and on 

 the costa, the rest glabrous, often glossy ; fr. bipinnate, coriaceous ; pinnl. 

 shortly petiolate, oblong with an acuminated point ; pinnatifid $ or f of the way 

 to the costa ; lobes oblong-ovate, often rather acutely serrulate ; costa and simple 

 or forked veins of the same colour and texture as the frond, bearing small,
