 —Kze. Analect. t. 17. / 2.— 6"-8" high ; segments 4"'-C" diam.— Hab. Jamaica!, Pd., 

 Wils., AL, on limestone rocks, S. Anns Bay, S. Thomas, i. E. ; [Cuba !, Haiti]. 



88. A. serrulatum, L. Leaf piunatisect or once-" twice " 2-pinnatisect at the base, 

 produced into a pinnatifid or serrate apex (the longer, terminal segment) : segments 15-20- 

 jugal, chartaceous, dimidiate-oblong or half -ovate, blunt, inferior shortly petiolulate, superior 

 gradually smaller, sterile argutely denticulate (except only at the base) : petiole short, pu- 

 bescent, channelled-cylindrical ; sori usually confined to the upper margin, contiguously 

 interrupted.— SI. t.'SS.f. 2.— A. deuticulatum, Mett. ! in PL Lechl. 2319 (non Sw.). 

 Sloane's figure was compared by Sir W, Hooker with A. pulverulentum, L., but the continu- 

 ous son, and the stout, 4-gonal petiole distinguish at once that large species. — Usually 6 -

 hills : [Cuba !, (Wr. Cub. 880) ; Peru !].

 10-20-jugal, membranaceous, broadly dimidiate-oblong (or half-roundish), blunt, lobulato- 

 crenate at the upper margin, inferior shortly petiolulate : petiole slender, channelled-cylin- 

 drical, polished, glabrate : rhachis puberulous ; sori reniform, distantly interrupted, con- 

 fined to the upper margin. — Hook. Spec. t. 73. A. — Allied to A. dolabriforme, Hook., and 

 A. lunulatum, W., but in both these the segments are much longer-petiolulated. — 8 -V2> 

 high, delicate ; segments 6"'-8"' long, 4'" broad. — Hab. Jamaica !, M'Nab ; [Cuba !]. 



90. A. villosum, L. Leaf 2-pinnatisect : primary segments few-, secondary 10-15- 

 jugal, chartaceous, dimidiate-oblong-lanceolate or trapezoid-oblong ; subsessile, terminal 

 rhomboid-lanceolate, entire : petiole channelled-S-gonal, rusty-hairy ; sori continuous, 

 lining the upper margin and round the apex about one-half of the lower one. — SI. t. »«>•

 long, 4"'-5'" broad.— Hab. Jamaica (Sw.), iu woods; S. Vincent!, Guild.; Trinidad!, 

 Sch. ; [Panama ! to Brazil !] .

 condary 8-18-jugal, herbaceous, glaucescent beneath, dimidiate, trapezoid-oblong or subfal- 

 cate-oblong, serrate at the bluntish summit only, shortly petiolulate, terminal narrow, ser- 

 rate : petiole channelled-'A-gonal (or 4-goual at the base), polished, hairy or glahrescent : 

 rhachis villous-bairy ; sori contiguously interrupted, confined to the upper margin, and re- 

 appearing often at the lower margin of the oblique apex, rarely extending to it. — A. pnono- 

 phyllum, Kth. A. striatum, Sieb. Mart. 370 (non Sw.). A. intermedium, Hook, (non Kze). 

 A. brasiliense, and fructuosum, Lk. — Variable, nearly allied to A. villosum, L. — V-2' high ; 

 secondary segments 1" long, 4"'-5'" broad. — Hab. Jamaica!, Wiles; Dominica !, Imr. ; 

 Trinidad ! ; [French islands ! ; Mexico ! to Brazil !]. 



92. A. triangulatum, Hook, (non Kaulfi). Leaf 2-pinnatisect: primary segments 

 3-2(-4)-jugal, subapproximate : secondary 15-20-jugal, chartaceous, green on both sides, 

 dimidiate-oblong-lanceolate, subfalcate bluntish, serrate along the upper margin, shortly 

 petiolulate, terminal narrow', serrate : petiole channelled-Z-gonal , \-gonal below, rusty- 

 hairy ; sori short, confined to the serralures of the upper margin, interrupted by its sin1 j°f,' u 

 ties. — H'-2' high: petiole longer than the blades; secondary segments 1" long, 3 -4 

 broad. — Hab. Jamaica !, Wils. ; Trinidad !, Cr. ; [Cuba ! to French islands ! ; Guiana IT.

 subsessile, sterile serrulate along the upper margin and round the apex, terminal narrow, 

 serrate : petiole wholly channel) ed-4s-gonal, polished, rusty-hairy ; sori oblong, contigu- 

 ously interrupted along the upper margin and usually round the apex. — A. prionophyllnm, 

 Hook, (non Kth), Eat. in Wr. Cub. A. triangulatum, Kaulfi sec. Kze. : but Kaulfusss 

 description agrees better with A. tetraphyllum, W. — 1'-3' high ; secondary segments 8 - 

 10'" long, 3"'-4'" broad.— Hab. Jamaica; S. Vincent!, Guild.; Trinidad!, Sch. ; C Cuba ! 

 to Guiana!].
