32 G. ALSOPIIILA. 



1 . A. blechnoides, Hk. ; fr. pinnate ; pinnae coriaceo-membranaceons, glossy, 

 0-12 in. ]., lanceolate, suddenly acuminate and serrate at the apex ; sori (mixed 

 with copious long hairs) scattered in very irregular lines near the costa, sometimes 

 extending towards the margin. Hk.Sp. 1. p. 35. Metaxya, Pr. Polypod, Sw. 

 P. Parkeri, Hk. & Gr. Ic. F. t. 232. 



Hab. W. Ind. and Trop. America. Remarkable for the large nearly entire pinnae. 



2. A. phegopteroides, Hk. ; caud. 3 ft. 1. ; St. unarmed, short, 3-4 in. 1., clothed 

 with large lanceolate, glossy, black scales having a pale margin ; fr. 1^-2 ft. 1., 

 subcoriaceous, black -green above, paler beneath, villous on both sides, especially 

 beneath, with long spreading hairs, broad-lanceolate, acuminate, pinnatifid at 

 the apex, lowest ones reflexed ; pinna? sessile, 3-4 in. 1., 8-9 lines w., oblong, 

 shortly and bluntly acuminated, deeply nearly to the costa pinnatifid ; lobes 

 oblong, very obtuse, entire, the margin a little recurved ; veins forked ; sori at 

 Ihe fork, in a line between the costule and the margin ; rachis and costce beneath 

 shaggy with whitish hairs, mixed with brownish, narrow scales. 



Hab. Tarapota, E. Peru, Spruce, n. 4020. A very peculiar species from the shortness 

 of the stipes, the simply pinnato-pinnatifid frond (resembling some Lastrea or Phegopteris), 

 and the hairy clothing, brown and shaggy beneath. 



3. A. paleolata, Mart. ; "fr. bipinnato-partite, on both sides, but especially 

 beneath, pubescent ; veins and veinlets beneath densely clothed with ovate, white 

 scales ; st. and rachis aculeate ; common and partial 'rachi?, and veins strigillose 

 above; pinnce linear-oblong, shortly acuminated ; pinnl. linear, shortly acumi- 

 nated, pinnatifid, the apex serrated ; segm. linear-oblong, subfalcate, toothed in 

 the upper margin ; the ult. ones confluent, so as to form serrated pinnae ; sori 

 4-8, in the lower part of the segm., arranged in 2 rows." Mart. Crypt. Bras. t. 43. 

 Hk. Sp. 1 . p. 44. Als. Sellowiana, Kl. Cyathea, Pr. Hk. Sp. \.p. 23. A. ferox, 

 y Hk.Sp. 1. p. 41. 



Hab. Brazil ; N. Granada ; Peru, Lechler, n. 2190 ; Spruce, n. 4322. Very faithfully 

 represented by Martius, and equally faithfully described ; but in my specimens the 

 scales (paleolae) are tawny and copious only on the immature fronds. 



4. A. Tcenitis, Hk. ; fr. ample, coriaceo-membranaceous, bipinnate ; pinnl. 

 distant, 3-5 in. ]., lanceolate, acuminate, glabrous, subentire, petioled ; petiole 

 articulated on the rachis ; sori in a single series, equidistant between the costa 

 and the margin, mixed with long, copious hairs. Hk. Sp. 1. p. 35. A. excelsa, 

 Mart. Or. Bras. t. 27 and 37. Trichopteris, Pr. 



Hab. Brazil. 



5. A. elegans, Mart. ; st. aculeated ; fr. bipinnate, carnoso-coriaceous ; pinnl. 

 distant, 2-2 in. 1., linear-lanceolate, suddenly acute, obtuse at the base, petioled, 

 slightly ferruginously woolly and subpaleaceous beneath ; sori in 2 or 3 series, 

 forming an unequal, broad, and more or less interrupted series nearer the costa 

 than the margin. Mert. PI. Cr. Bras. p. 63 and 38. Hk. Sp. 1. p. 36. 



Hab. Brazil ; apparently rare. 



6. A. marginalia, Kl. ; fr. ample, subcoriaceous, glabrous, bipinnate ; prim, 

 pinnce 12-14 in. 1., 4 in. w., pinnated, pinnatifid at the apex, oblong, acuminate ; 

 pinnl. approximate, truncated at the base, quite sessile, oblong, subfalcato-obtuse, 

 entire, subsinuate at the margin ; sori in a single line, forming a flexuose conti- 

 nuous series a little within the margin ; prim, rachis very paleaceous. Kl in 

 Linn. W. p. 542. 



Hab. Brit. Guiana, R. Scliomlurylc, n. 1129. A well-marked and very distinct species. 

 ** Bi-tripinnate or decompound. Sp. 6-63. 



7. A. Micrsii, Hk. ; racMs aculeate ; fr. firm-inembranaceous, bipinnate, 

 glabrous ; prim, pinnce 2 ft. or more ]., pinnated to the very apex ; pinnl.
