pilose." Hook. fil. PI. of Galapag. in Linn. Trans, xx. p. 

 168. 



Hab. Charles Island, Galapag^os, Chas. Dartvin, Esq. — " A small species, 

 most nearly allied to one that is a native of New Zealand, in which the upper 

 margins of the piunas are crenale." Hook. Fil. 



91. A. Henslovianum, Hook, fil.; "fronds bi- or rarely 

 tripinnate elongato-ovate, primary pinnae attenuated, secun- 

 dary few, pinnules lax divaricated shortly petiolate rhombeo- 

 lunulate membranaceous above crenately lobate, sori in the 

 bottom of the lobes rather large, rachis puberulous stipes 

 rufo-bnmneous." Hook.Jil. I. c. p. 169. 



Hah. James and Charles Islands, Galapaa^os, C. Darwin, Enq. — As the 

 affinities of this and the jireceding species are not alluded to, and since I do 

 not possess sj)eciniens, the place of them in the genus is doubtful to me. 



92. A. speciosuin, Hook. ; large, frond ovate acuminate (3 

 feet long) tripinnate, pinindes chartaceous glabrous petiolulate 

 cordate deltoid or subrhomboid with a rather unequal base 

 lobato-pinnatifid, lobes cuneate truncated all soriferous at the 

 apex, sori linear as long as the lobe, stipes very stout dull 

 ebinieons subscabrous, rachis glossy pubescent on the upper 

 side. (Tab. LXXXV. C.) 



Hab. Abnut the villaf^e of Sasaranjra, 1^1 Equador, Pacific side, See- 

 viann, n. 953, Aug-. 1847. Peru, Mr. Mc Lean. — This is one of the finest 

 and best marked species with which I am acquainted, and has really pinna- 

 tifid pinnules. It is true that this pinnaiifid character in the younger leaflets 

 is an indication that as the {frovvlh advances they will break up into other 

 pinnae : but the ultimate pinnules (and I have seen only Iripinnated speci- 

 mens) in the most perfect form are equally pinuatifid. These pinnules are 

 commonly an inch and more long, all the lobes cuneate and truncated, and 

 every lobe is terminated by a transverse, linear, rather narrow involucre oc- 

 cupying its whole breadth. The stipes is nearly 2 lines wide, but I do 

 not pos.sess the lower portion. 



93. A. tenerum, S\v. ; frond rather large (1^^ — 2 and even 3 

 feet) 3 — 4-pinnate, pinnules all petiolate submembranaceous 

 glaucous-green (very deciduous when dry) rhomboid the 

 cuneate base very unequal the margins irregularly lobed (the 

 sterile ones deej)ly so and laciniated) lobes and lobules retuse 

 soriferous, sori rather numerous approximate, involucres short 

 oblong-reniforra, stipes and rachis ebeneous glossy every- 

 where quite glabrous. Sw. Fl. Ind. Occ. iii. p. 1719. Syn.

 nules shorter more approaching to orbicular, fertile ones
