 Griseb.). A. gibbosa, Kl. {Moore). 



Hab. W. Indies ; Cuba, C. Wright, with large, glossy, lanceolate scales at the base of 

 the stipes, 1 in. or more 1. — I fear different authors have different species in view under 

 the name of Ah. aspera and muricata. See remarks in Sp. Fil. (I. c), and consnlb the 

 W. Indian Alsophilce in Grisebach, the species of which I cannot match with my speci- 

 mens. It is necessary for an author, therefore, to be very cautious in quoting synonyms 

 and localities. A reference to good figures is better than to the most laboured descrip- 

 tions, often made from imperfect specimens. 



13. A. ferox, Pr. ; more or less hirsute, especially on the veins ; rachis 

 and 5^. sharply aculeated ; //•. bipinnate ; pinnl. sessile, broadly lanceolate, 

 narrow-acuminate, deepl^'-pinnatifid almost to the costa ; lohes linear-oblong, 

 falcate, serrate, having small bullate scales beneath ; veins forked ; sori copious, 

 but not wholly covering the lobes. — Hk. Sp. \. p. 41. A. arraata, Mart. Cr.

Hab. Brazil, Guiana ; Amazon, Spruce, u. 614. — Bordering too closely on more than 

 one other supposed species of this group. Satisfactorily represented in the figures above 

 quoted, if the species be truly distinct. 



14. A. leucolepis, Mart. ; " st. aculeate ; fr. bipinnato-partite, slightly stri- 

 gilloso-hirsute on the veins and veinlets above, beneath paleaceous with long 

 and small white scales ; part, rachis unarmed ; pinnce linear-acuminate, pinna- 

 tifid ; lobes small, linear-lanceolate, subfalcate, sinuato-dentate ; sori on all the 

 lobes 10-12.''— Mart. Cr. Bras. p. 70. t. 46. H/c. Sp. 1. p. 41. 



Hab. Brazil, Mariius, Gardner, n. 5329 and 5331 ; Venezuela, Fendler, n. 53 (young 

 state). — Some of my specimens (which I am disposed to refer to A. atrovirois, Pr., 

 A. compta, Mart.) are very little removed from A. leucoleins, judging from the 

 figure, I. c. 



15. A. infesta, Kze. ; "fr. bipinnate ; pinnl. unequal at the base, pinnatifid, 

 acuminate ; lobes oblong-falcate, rather obtuse ; sori uniseriate, approaching 

 the margin ; rachis puberulous, furrowed and paleaceous ; st. chaffy above, 

 aculeate below." — Kze. PI. Cr. Poepp. p. 98. Hk. Sp. 1. p. 42. A. phalerata,

Hab. S. America and W. I. Islands ; Para, Spruce, n. 22 ; Peru, Lechler, Spruce, n. 

 5724 : Venezuela, Fendler, n. 56. — On many of my specimens, bearing this name, the 

 upper portion of the rachis of the primary pinnae is distinctly winged. 



16. A. atrovirens, Pr. "fr. compound ; pinnce pinnate, subpetiolate ; pinnl. 

 sessile, broadly lanceolate, coarsely and pinnatifidly dentato-serrate ; sori scat- 

 tered, arising from an hemispherical recept. ; st. with short spines. (Ai'bores- 

 cent ?)." — Polypod. atro-virens, Langsd. et Fisch. p. 12. t. 14. Hk. Sp. 1. p. 46.

17. A. elongata, Hk. ; sharply aculeated, glabrous, except on the rachis above ; 

 fr. bipinnate; ^>rm. pinnce 2-3 ft. 1., 8 in. w. ; pinnl. _ 6 in. and more 1., lan- 

 ceolate, much elongated, pinnatifid nearly to the rachis, terminating in a long, 

 narrow, serrated, caudate acumen ; lobes 5-6 lines 1., remote, linear, rather 

 acute, rigid, much falcated, the margins recurved, serrated ; veins twice or thrice 

 forked from near the base ; sori numerous, covering the entire segments exce])t 

 at the apex ; bullate scales none, or quickly deciduous ; recept. very hairy. — Hk.

Hab. Columbia, IlaHivcrj, n. 1528 ; Central America, Barclay, Seemann. — Since first 

 I published this, I have received specimens from otiier collectors, identically the 

 ame with our plant, and to one of which Mr, J. Smith hau given the name ijf Als.
