including the stipites, with 2-3 small roimded piiinnc to the side, quite soriferoiis, was gathered at Old 

 England, below the Cinchona Plantation. '1 he name was founded on Plumier's Fil. t. o9, which is repre- 

 sented as much larger, with only 5-6 pinua) to a side, the lower with a deltoid auricle on the superior 

 base, and having a cylincb'ical, j)ro8trate, creeping rootstock, — clearly a dilferent species to that to which 

 the name is now applied. Moore regarded it, probably correctly, as a Diplazinm. 



12. A. ohtusifoliuiii. Linn. — Rootstock strong, repent, scurfy, the end finely scaly, stipites approximate, 

 erect, 4 8 in. 1, grey-green or darker, fiattish or channelled, naked, rachis conform; fronds pinnate, acumi- 

 nate or obtuse, base truncate, herbaceous, veiy thin and pellucid or thicker, dark green naked, \-\ ft. 1. 



in. w. ; pinn«3 sjireading, usually open or their own width apart, 1^-3 in. 1, ^-f in. w. acuminate, 

 blunt or broadly rounded, the base cuneate or truncate, expanded and auricled or not on the upperside, the 

 under oblicpiely cut away, sessile or slightly stipitate, the margin entire, serrulate or inciso-serrate ; veins 

 piniuite, branches open, very oblique, simpleor once or twice^forked ; sori linear, straight or curved, \-\ in. 1. ; 

 involucres nsirrow flat. — Plum. Fil. t. 07. Hook and Grev. Icon. t. 239. 



On rocks near streams rivulets and water falls in moist woods and forests. There are two forms, one, 

 of which Plumier's tigurc well represents, with thin, broadly rounded, plain-margined pinnae, and the other 

 thicker of substance, acute or acuminate, but very variable, and more or less toothed or deeply incised. I 

 have net seen Jamaica specimens, but Heward recorded it as common in the woods near Old England Plan- 

 tation, Manchester, collected by him in 1823-6. 



13. A. s(i/ici/oliii)u, Linn. — Stipitts tufted from a short, fibrous, finely scaly-crowned rootstock, few 

 slender grey-green, naked, 6-10 in. 1. ; rachis similar, slightly margined above ; fronds pinnate, ^-1^ ft., 1. 

 4-8 in. w. light green naked, herbaceous ; pinn;c spreading, 4-10 to a side and a similar terminal one, 

 apart or distant, the lowest as large or little reduced, 3-5 in. 1. ^-1 in. w. equilateral, base cuneate, the lower 

 stipitate, tapering and mostly attenuated outwards, margins even or slightly repand, not toothed ; veins pin- 

 nate, oblique, once or twice forked, short of the edge, sori linear on the anterior veins, J— ^ in. 1. usually 

 equally short of both mid-vein and margin; involucres pale, narrow, flat. 



On trees, logs and rocks of woods and shady places ; more or less drooping and pendant in habit, the 

 substance being very pliant. This is ascribed to Jamaica by Swartz, no subsequent collector apparently 

 having fovmd it. The cuneate base, equal on both sides, not at all expanded or auricled, of the pinnae 

 readily distinguishes it. y 



14. A. anisoplii/llum, Kze. — Stipites ^-1 ft. 1. scaly at first at the base; fronds pinnate, more or less 

 pendent, glabrous, chartaceous, cloudy-green, l|-2 ft. 1. 5-8 in. w. the rachis naked and grey-green ; pin- 

 nse 3-5 in. 1. f-1 in. w. alternate, spreading, acuminate, distantly toothed, base deeper or not on the 

 upper side, the lower distant ones not, or very little, reduced and shortly petiolate, upper ones apart, sessile, 

 with a similar terminal one ; veins oblique once or twice forked, terminating in the marginal teeth ; sori 

 2-3 li. 1. ; sunk, confined to the base of the anterior veinlets, but not reaching the midrib ; involucres 

 ample, finally revealing the tumid sori. — Hook Sp. Fil. vol. 3 t. 166. 



Readily distinguished from its neighbours by the short tumid sunken sori, the beds of which are con- 

 spicuous on the upper sides of the fronds. The description is taken from Cuban specimens gathered by 

 Linden ; I have seen no local ones. The species has a very wide range in both the Eastern and Western 

 Hemispheres. 



15. A mtriciilatitm, Linn. — Rootstock fibrous, erect or oblique, tomentose, and with minute reticu- 

 lated brown scales ; stipites tufted, ^-1 ft. 1. channelled, grej'-green, naked ; rachis similar ; fi'onds pinnate, 

 6-12 in. 1. 4-8 in. w. light green, naked, herbaceous ; pinna; spreading, petiolate, more or less apart, 2-4 

 in. 1. ^-1 in. w. acuminate, bi-serrulate, teeth evanescent outwards, iaferior base shortly cut away, superior 

 expanded into a rounded or subdeltoid auricle, lowest pair not reduced, terminal lobate and inciso-serru- 

 late, veins pinnate, once or twice forked, flabellate in the aiiricle, sori very oblique, \-\ in. 1. much short 

 of the margins, involucres narrow, flat, even-edged.— Plum, Fil. t. 60. Hook Sp. Fil. vol. 3 t. 171. 



Frequent in woods and forests below 2,000 ft. alt. on trees and rocks ; with the habit of growth of 

 salici/'olitiin, from which the aiiricle at the base of the pinna; clearly distinguishes it. This latter varies 

 in shape with the degree of development, usually it is rounded, but when large it more or less deltoid.
