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



88. A. serrulatum, i. . Leaf pinnatisect or once-" twice" 2-piniiatiseot 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 argutehj denticulate (except only at the base) : petiole short, pu- 

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

 interrupted.- — SI. t. 35. /. i. — A. denticulatnm, Mett. I in PI. Lechl. 2319 (non Sio.). 

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

 ous sori, and the stout, 4-gond petiole distinguish at once that large species. — Usually 6''- 

 8" high ; inferior segments 4'", terminal 6"'-8"' long. — Hab. Jamaica ! (Sm.), on shady 

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

 crenate at the upper margin, inferior shortly petiolulate ; petiole slender, channeUed-cyliu- 

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

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

 A. lunulatum, W., but in both these the segments are much longer-petiolnlated. — 8"-12" 

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

 jngal, chartaceous, dimidiate-oblong-lanceolate or trapeeoid-oblong, snbsessile, terminal 

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

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

 rate : petiole channelled-i-gonal (or 4-goual at the base), polished, hairy or glabrescent : 

 rhachis villous-hairy ; 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. priono- 

 phyllum, Kth. A. striatum, &ei. Mart. 370 [non Sw.). A. intermedium, fibo^. {nonKie.). 

 A. brasiliense, and frnctuosum, Li. — Variable, nearly allied to A. villosum, L. — 1'-2' high ; 

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

 Trinidad ! ; [French islands 1 ; Mexico I to Brazil !]. 



92. A. triangulatum, ^(70^. {non Kaulf^. Leaf 2-piDnatisect : primary *ey)K?»is 

 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, i-gonal below, rusty- 

 hairy ; sori short, confined to the serratures of the upper margin, interrupted by its sinuosi- 

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

 broad. — Hab. Jamaica !, Wils. ; Trinidad I, Or. ; [Cuba ! to Erencli islands ! ; Guiana !1.

 6-2-jvigal : secondary 10-24-jugal, chartaceous, dimidiate-oblong, rounded at the apex, 

 subsessile, sterile serrulate along the upper margin and round the apex, terminal uai'row, 

 serrate : petiole wholly channelled-ii-gonal, polished, rusty-hairy ; sori oblong, contigu- 

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

 Hook, (fion Kth.), Eat. in Wr. Cub. A. triangulatum, Kaulf. sec. Kze. : but Kau'lfuss's 

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

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

 to Guiana!].
