remote, petiolate, 5-G in. ]., 5-6 lines w., spreading, linear-lanceolate, subflexuose, 

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

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

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

 Hab. Organ Mountains, Brazil. 



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

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

 glabrous, pinnatifid at the apex ; prim, pinna? 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 ; Brazil, Spruce, n. 2115 ; Venezuela, Fendler, n. 344 

 and 491 ; E. Peru, Spruce, n. 4715. 



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. 

 1. p. 48. Polypod. ScJdecht.; an Als. ptmgens, Klf. ? 



Hab. Mexico, ScMe.de, Liebmann, in lib. nostr. ; B. Guiana, Rd. Schomburgk (" Als. 

 pungens," Kl. in lib. nostr.) ; Amazon, Spruce, n. 2115. Very near A. procera, but more 

 deeply pinnatifid, and with blunter lobes. 



f 10. A. armata, Pr. ; "fr. bipinnato-partite ; st. aculeate ; rachises of the 

 pinna? aculeato-nodulose on both sides, together with the veins above hirsute ; 

 pinnce and pinnl. linear-lanceolate, acuminate, beneath hairy and paleolate, 

 subfalcate, rather obtuse, crenate ; sori 12-20 on the lobes." Mart. Cr. Bras, 

 p. 73. t. 49 (A. Swartziana). Hook. Sp. 1. p. 40. Polypod. Sw. 



Hab. S. America and W. Indies. My numerous specimens sufficiently accord with 

 Martius's figure ; but neither that nor his description exhibits any marked feature by 

 which it can be distinguished from some of its allies. 



11. A. Gardneri, Hk. ; aculeate; everywhere clothed with brownish woolly 

 hairs ; pinnl. lanceolate, acuminate, sessile, deeply pinnatifid nearly to the costa, 

 paleaceous with numerous small, bullate scales beneath ; lobes oblong, very 

 obtuse, entire, covered with sori even to the acuminated apices of the pinnules. 

 Hk. Sp. I. p. 41. j3 less hairy. Cyathea nigrescens, Kl. in Hb. nostr. 



Hab. Brazil ; Caraccas, Birsliell. Very hairy ; but my specimens are unsatisfactory. 

 It has some affinity with A. Poeppigii, and perhaps with A.plagiopteris: too hairy for 

 A. armata. It must be confessed the aculeated S. American Alsophilw are in a state of 

 great confusion. 



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

 aculeated too) and partial rac/iis 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, 

 deciduous, bullate scales beneath ; sori very deciduous, intermediate between the 

 costa and margin ; recept. elevated, with few hairs. Hk. and Gr. Ic. F. t. 213-215.
