nelled, gray, naked, or fibrillose at the base ; fronds erect, 5-9 in. L, 

 1^-2 in w., naked, dark green, paler beneath, the base cuncate-rounded 

 and often viviparous at the bottom of the costa on the upper surface, 

 the apex acuminate, cuspidate or tapering to a fine point, marginal teeth 

 faint at the base, deepest and sharpest at the extreme apex, veins in 

 groups of 5-7, forked, parallel ; sori linear, long and short, the form 

 in. 1. on the lowest anterior veinlet and mostly double ; involucres pale, 

 narrow. — Diplazium, Swartz 



Frequent in mountain forests, generally in wet districts and on 

 broken stony ground, at 2,000-3,000 ft. alt , extending from the eastern 

 to the central and western parishes. Casually the contiguous branches of 

 the separate vein-groups unite, forming a costal arch. The only local 

 species with entire fronds. Hooker describes a Guadaloupe variety with 

 free elliptical auricles on each side of the frond. 



38. A juglandifolium, Lam. — Stipites strong, erect, ft 1., de- 

 ciduously paleaceous at the base; fronds pinnate, ft 1., f-1 ft. w., 

 firm, bright green, glabrous, a free, often sinuate terminal pinna, and 

 with x-lu pairs of alternate subdistant, spreading lateral ones 5-7 in. 

 L, 1\ in. w., acuminate, somewhat unevenly serrulate, cuneate or 

 rounded at the base, the lower stipitate, highest of all slightly adnate, 

 veins free, forked from the base, the anterior branch usually simple, the 

 posterior forked from above or below the middle, sori linear nearly 

 straight, reaching from the midrib to near the margin ; involucres flat, 

 brown, single or double. — Diplazium, Sw. A. Roemerianum. Kze. 



Apparently infrequent, though possibly common in limited localities. 

 I have two fronds gathered at mid elevation in the St. Andrews moun- 

 tains ; situation not recorded, and there is one in John Smith's ferns in 

 the British Museum, labell- d "Jamaica, 1845." I have also a ( uban 

 specimen gathered by Linden, no 1896. Xearlj* all authors quote for 

 this Sloanes t, 37, but his specimens in the British Museum prove that 

 the figure is of a barren frond of Acrostichum cervinnm. Sw. The 

 species ie readily recognized from the two following by the separate 

 terminal pinna, the same in form as the lateral, though often larger. 



39. A. flavesrens, Mett — Stipites ft. 1. strong, erect, with a few 

 deciduous scales at the dark coloured base ; rachis similar ; fronds pin- 

 nate, 1-2 J ft. 1. f-1 ft. w. chartaceous, pellucid, grass green, paler be- 

 neath, glabrous, the upper part pinnatifid, passing through lobes gra- 

 gually into the serrate acuminate point, base truncate and not reduced ; 

 pinnae nearly horizontal, the lower distant, 4-6 in. 1. IJ-lf in. w. the 

 base petiolate and obliquely cuneate, the upper ones becoming more 

 rounded and finally adnate, acuminate and freely serrate outwards, the 

 teeth within this shallow and appressed ; veins laxly open, at a wide 

 angle, once or twice forked above the base ; sori linear, usually on the 

 lower outer branch, reaching nearty from midrib to margin, or short of 

 both ; involucres very narrow, membranous.- -Diplazium, Kze. 



Infrequent apparently in mountain woods, where it was gathered first 

 by Bancroft and Wilson, and subsequently by Xock at 2000-3000 ft. 

 alt. This has fewer, differently shaped, pinna?, serrated without being 

 sinuated or lobed, fewer, more open, veins, and sori confined to a single 

 veinlet of each group, thus being uniserial as compared to the next two 

 species, which like this have no distinct terminal pinnae, being taper- 

 ingly reduced pinnatifid and lobed at the top of the fronds.
