is widely spread in both the Eastern and Western Hemispheres has been 

 found in Cuba. It has an erect caudex, caespitose paleaceous, stipes, 

 oblong-lanceolate, bipinnate or tripinnatifid fronds, the base usually nar- 

 rowed, pinnae 3-8 in 1. f -\\ in. w. and toothed or pinnatifid pinnulae j- 

 f in. 1. and subreniform or oblong curved involucres. It should be 

 looked for at high elevation in Jamaica.) 



56. A. bruneo-viride, Jenm. — Rootstock stout, erect, crown dotted 

 with dark scales ; stipites caespitose, strong, erect, brown 2-3| ft. 1. palea- 

 ceous at the base ; fronds 3-4 ft. 1. 2-3 ft. w. tripinnate or quadripinna- 

 tifid, chartaceous, pellucid, naked except the costae and costulae which 

 are fibrillose, light or dark brown-green ; pinnae oblong lanceolate, 1J- 

 lf ft. 1. J-f ft. w. shortly petiolate, the lower deeper on the inferior side 

 pinnulae numerous, contiguous not sessile, 3J-5 in. 1. 1J-1^ in. w. the 

 point serrate acuminate ; tertiary segments oblong rounded, firm and 

 nearly sessile, contiguous, f -1 in 1. 2^-4 or 5 li. w., lobed or deeply pin- 

 natifid, the lobes oblong, rounded, 1J-2J li. 1., about half as w. and 

 narrow sinuses ; rachis wood-brown, channelled ; costae and costulae mar- 

 gined with green membrane ; veins pinnate, simple 2-3 to a side ; sori 

 copious li. 1. the lowest anterior double ; involucres tumid, pale brown.

Infrequent in moist forests at 5.000-6,000 ft. alt. Resembling the 

 next species in outline and cutting, but larger in all its parts, and of a 

 lighter colour. Both are near A. Sandwrchianum, Mett. Gathered by 

 Morris and Sherring on the slopes beyond the Govt. Cinchona Planta- 

 tion. With careless drying it turns black. 



57. A. Wilsoni, Baker. — Rootstock stout, erect or decumbent, clothed 

 with large blackish palea on the crown ; stipites caespitose, subangular 

 below and paleaceous, upwards channelled, dark puberulous, 1-2 ft. 1. 

 fronds tri or quadripinnate, H-3 \ ft. L ft. w. little or not reduced 

 at the base, the apex fully pinnate to the serrate narrow point, mem- 

 brane-herbaceous, pellucid, dull dark green, naked ; rachis costae and 

 costulae narrowly winged with lucent membrane, and scurfy- puberulous ; 

 pinnae nearly horizontal, the lower deflexed, numerous ft. 1. 3-5 

 in. w. oblong lanceolate, nearly sessile, pinnate to the serrate point ; 

 pinnulae very numerous, contiguous, often somewhat overlapping, 1^-3 

 in 1. in. w. the inferior usually a little reduced ; tertiary segments 

 oblong, blunt, dentate, pinnatifid or the inferior fully pinnatifid at the 

 base, contiguous blunt, J-f in. 1. 2-4 li. w., final lobes in the largest 

 states 1-2 li each way, veins simple or forked in the ultimate teeth or 

 lobes, sori ^— f li. 1. copious, involucres tumid, brown, inferior double. -

Frequent in dells and ravines of the moist forests of the ridges from 

 6,000-7,000 ft. alt. Like altissimumm similar situations it is sometimes 

 viviparous in the axils of both pinnae and pinnulae. Small fronds are 

 tripinnate, but the larger are often fully quadri pinnate. The narrow 

 channel of the rachis and costae is almost concealed by the inflexed 

 membrane of the margins. The final cutting is much finer than in 

 brtmeo- viride. 



58. A. marginatum, Linn. — Rootstock very stout, erect, scaly, stipites 

 caespitose. erect, stout, 2-3 ft. 1. base paleaceous ; fronds erect, 4-6 ft. 1. 

 2J-3J ft. w. simply pinnate, membranous or firmer, pellucid, glabrous,
