broad ovato-lanceolate acuminated, pinnules very shortly pe- 

 tiolulate (almost sessile) bright green rather firmly membrana- 

 ceous dimidiato-oblong or lanceolate very obtuse or more or 

 less acuminate deorsely falcate (rarely straight) broadest at 

 the superior truncated base (but which is obtuse or rounded 

 off), superior margin and apex serrated and slightly lobed, 

 lobes soriferous, sori on tlie upper margin only linear or nar- 

 row-oblong straight angled, stipes on one side and the rachis 

 moderately but distinctly pubescent. (Tab. LXXXIV. C). —

Hah. Brazil (Kaulfuss). Dry woods, Sierra de Santa Brida, Prov. of 

 Goyaz, Brazil, Gardner, 4074. — I liave drawn my description mainly from 

 dried specimens and living plants sent from the Botanic Garden of Berlin, 

 with which Mr. Gardner's plant quite coincides. It is clearly a good 

 species, that is, different from any other that has come under Mr. Smith's 

 or my observation ; but as I have already observed, A. angustatum, Kaulf. 

 (also from Brazil), is probably a mere form of it; possibly, too, A. humile, 

 Kze. ; and, if any of the pinnules bear sori on the lower as vvell as the 

 upper margin (which I have never found to be the case) it would ap- 

 pear almost identical with A. tetmgonum, Schrad. and Martins, Ic. PI. 

 Crypt, t. 63. 



58. A. hiimile, Kze. ; "frond subpcdate, branches 3 — 5-pin- 

 nate, pinnae oblong dimidiate subfalcate superior base trun- 

 cated, auricle obtuse dentated, lower base nearly straight, 

 superior and exterior margin of the sterile ones sharply ser- 

 rated, of the fertile ones crenated, sori oblong distinct, rachis 

 and stipes short paleaceo-hispid." — Kunze,in Linncea,\x. p.

Hab. Woods of Huallaga, Province of the mission of Tocache, Poeppig 

 (Ku7ize). — "Nearest to A. curvattim, Kaulf. Enum., which differs in the 

 superior base of the pinnule being rounded, not auriculated, in the margin 

 being inciso-dentate, the lacinice soriferous. Scarcely a foot high ; stipes 

 nearly equal in length to the frond." — Kze. I. c. 



59. A. patens, Willd. ; frond flabelliform bipartito-pedately 

 divided tripinnate, secondary pinna) lanceolate obtuse straight, 

 pinnules chartaceous (brown when dry) dimidiate-oblong very 

 obtuse generally straight sometimes deorsely falcate, upper 

 base truncate sterile ones crenato-lobate the sinuses (4 — 5 on 

 a pinnule) soriferous, involucres reniform-orbicular large with 

 a deep sinus at length coriaceous pale and submembranace- 

 ous at the margin, stipes and rachis ebeneous very glossy tlie 

 latter pubescent. — Willd. Sp. PI. v. p. 439. Klotzsch, in
