 pin?ice and pinnl. alternate, remote, subsessile, the latter lanceolate, unequal at 

 the base, shortly acuminate, deeply pinnatifid ; segin. oblonii', falcate, sinuato-

Hab. Mexico, Schiede, Liehmann, in Hh. nostr. ; B. Guiana, Rd. SchomhurrjTc (" Als.

 deeply pinnatifid, and with blunter lobes.

 pinnce aculeato nodulose on both sides, toi^ether with the veins above hirsute ;

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

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

 which it can be distinguished from some of its allies. 



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

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

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

 obtuse, entire, covered with sori even to the acuminated apice-; of the pinnules. — 

 Hk. Sp. 1. p. 41. — j8 less hairy. Cyathea ulgrescens, Kl. in Hb. nostr. 



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

 It has some affinity with A. Poeppigli, and perhaps vf'iih A. pTarjiopteris : too hairy for 

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

 great confusion. 



12. A. aspcra, Br. ; st. and racM^ strongly aculeated, main (sometimes strongly 

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