more confluent, shorter and more ovate, not incurved ; basal ones often 

 rather recurved. 



Frequent or infrequent in localities in Manchester and other of 

 the central parishes, on the sides of rocks in woods and other shaded 

 places. Resembling myriophyllum in form and cutting, but uniformly 

 much smaller, different in colour, and with the final segments 

 rather curved or falcate when single. Rather more finely cut than 

 Hooker's figure cited above shows. By spreading on one side of the 

 veinlet the sori appear quite lateral. When the involucres are con- 

 cealed by the matured sori, the plant looks like a delicately cut Gym- 

 nogramme. Wright 1,029, Mount Verde, Cuba. The variety which 

 is smaller, and not dwindled at the base was found, once only, in St. 

 Andrews Parish near Mount Moses by the Rev. Sherman B. Wilson 

 in 1874. 



33. A. rhizophyllum, Kunze.-Stipites slender, tufted on a small 

 fibrous, usually upright, root-stock, |-3 in. 1. channelled, margined, 

 brown or dark-green, naked ; rachis similar ; fronds lanceolate or 

 oblong-lanceolate, 6-10 in. 1. 2-3 in. w. bitripinnate membranous, 

 dark green, rather glossy, naked often viviparous and radicant at or 

 near the acuminate apex, gradually reduced at the base ; pinnae nearly 

 horizontal close or subdistant, nearly or quite sessile central 1-1 J in. 

 1. i-f in. w. the slender costae terminating in small spathulate, bi or 

 trilobed segments pinnulae cuneate-stipitate, composed of several lax 

 cuneate-flabellate, spathulate, obtuse final segments ^-J li. w. when 

 single ; veins and sori single in the final lobes, the latter \ li. 1. half 

 elliptical; involucres thinly membranous. 



Var. diminution, Jenm. Variable delicate, lax, prostrate, 1-2 in. l.J- 

 \ in. w. rooting at the end ; lobes of the short pinnae few, spathulate. 



Frequent in caves and on and under rocks in sheltered places at 5,000 

 to 6,000 ft. alt., common about the top of John Crow Peak. The 

 stipitate pinnulae and segment, which give a loose aspect to the cut- 

 ting refunded more spathulate lobes proliferous rachises, and fronds 

 reduced equally from the middle both ways, are its distinguishing 

 features. The rachises are leafy to the end, the buds when present 

 being produced within the apex. Some confusion exists as to its iden- 

 tity. Hook and Grev. Icon. Fil. t. 193, under this name, is A lunu- 

 latum, var. strictum, The variety is from the caves of John Crow 

 Peak, and is fertile from least to great of its varying stages. 



34. A. cicutarium, Swartz.-Stipites caespitose from an upright 

 fibrous, scaly, root-stock, 4-9 in. 1. gray-green or darker coloured, green- 

 margined, naked ; rachis similar, fronds bitripinnate, lanceolate-ob- 

 long, f-lj ft. 1. 3-6 in. w. membranous, light green, glossy, naked, 

 broadest at the truncate base, acuminate ; pinnae numerous, oblong- 

 lanceolate, nearly horizontal, close, or the lower subdistant, sessile, 

 acuminate, 2-3£ in 1. f-1 or more w. pinnulae ovate-oblong, close, 

 lowest pair of the lower pinnae reduced, broader and deeper on the 

 exterior side, 5-8 li. 1. 3-4 li. b. at the obliquely cuneate base ; 

 final segments emarginate or the interior ones tri or quadridentate, 

 the teeth sharp and J-^ li. w. in which the veins are simple ; sori 

 copious, ^mddy, one to each ultimate segment, half elliptical-oblong, 

 less than a li. 1. ; involucres pale, thin, conform. — SI. His. p. 92. Herb,
