Hab. Chili, Chnmisso, Pocppig, Berlcm. Conception, Cuming, n. 151. — 

 /3. Coidillieia of Peru, various places, Mathews, n. 1250. — The affinity of 

 this is (loul)tless wiih A. Chlleme, esjiecially what I have here called the 

 variety Jiiajun, and which, judging- from its locality and from its much 

 lari>er size, I am almost disjiosed to distinguish, under the name of A. 

 Periivianum, both from A. Chilense and from A. stdphureuni. From the 

 former it may be known by its larger size, in every res])ect, more distant |)in- 

 nules on longer petioles, paler colour of the pulverulent substance, scarcely 

 emarginale or retuse lobes and straighter sori; from A. Chilense by the 

 membranaceous pinnules and the ])resence of the sulphur-coloured pulveru- 

 lent substance. Kunze's figure, Analect. Pterid, 1. c, t. 22, f. 1, a., seems 

 lo be identical with my var. /a. as far as I can judge from the figure: but 

 it is sterile. 



89. A. sessilifoliiim, Hooli. ; frond ovate acuminate (8 — 10 

 inches) bi- (tri- r) ])innate, ])innules sessile (or only the lower- 

 most ones subpeliolulate) chartaceous glossy olive-green with 

 scattered hairs on both sides subrenifornii-obovale veiy ob- 

 liquely cuneate, ujjper base truncate the margin much but 

 not deeply lobed, lobes rather deeply emarginate the sinus of 

 the notch soriferous, sori copious large contiguous, involucres 

 lunulate (reniform but much curved) pubescent convex dark 

 brown, stipes subscabrotis and as well as the rachis castane- 

 ous glossy pubescenli-villous. (Tab. LXXXV. 13.) 



Hab. Chacapoyas, Peiu, Matheivs, n. 1855. — I place this near A. Chi- 

 lense, as its nearest aflinity, although my only two s|)ecimens are bi- not tri- 

 jiinnate; for it a good deal resembles it: but the pinnules are differently 

 shajied, the sori also, and one of the striking marks of this plant is the 

 sessile pinnules, or with the lowermost one on each pinna with a very indis- 

 tinct and hairy petiolule.
