|-| iii. br., ovate-lanceolate or linear-oblong, bipinnatifid ; pinnce reaching down 

 very nearly to the rachis, the lower ones ovate-oblong, cut about halfway down into 

 broadly linear segments ; substance membranaceous, the surface slightly hairy, 

 margin ciliated ; veins slender, the lateral v..4ns of the pinnse usually once 

 branched ; sori I to 2 to a pinna, terminal, tube sunk, mouth ciliated, spreading, 

 but scarcely two-lipped. Hk.Sp. 1. p. 131. 



Hab. West Indian Islands and Andes of Ecuador. This constitutes the genus 

 Eagatelus of Presl. 



56. T. lucens, Swartz ; caud. scarcely creeping ; st. tufted, 2-4 in. 1., stout, 

 densely clothed with long, fine, ferruginous hairs; fr. 0-18 in. 1., 2-4 in. br., 

 oblong-lanceolate, fully pinnate ; pinnce very close, often imbricated, transversely 

 crisped, pinnatifid about halfway down to the costa, the lower ones linear- 

 acuminate, 1-2 in. 1., !" in. br. ; substance delicately membranaceous ; rachis 

 densely tomentose ; costa and veins also rufo-villose ; sori as many as 20 

 to a pinna, occupying the greater part of both edges, tube quite sunk, mouth 

 with two lateral projections. Hk. Sp. 1. p. 139. t. 41. A. T. splendidum, 

 V. D. B. 



Hab. Tropical America, from Guatemala and Jamaica southward to Peru. 



57. T. Lambertianum, Hk. ; caud. scarcely creeping, tomentose ; st. stout, 4-5 

 in. 1., densely clothed with long, fine, reddish-brown hairs ; fr. 6-12 in. 1., not 

 more than 1 in. br., linear-oblong, acuminate, pinnate ; pinnce densely crowded, 

 imbricated, subsecund, oblong, obtuse, cut more than halfway down to the 

 rachis ; pinnl. again pinnatifid with linear-oblong segm.; substance thin, but 

 the frond much crisped, and especially the rachis, densely tomentose ; sori 4 to 12 

 to a pinna, the tube quite sunk, the mouth with two lateral projections. Hk. Syn. 

 1. p. 139. t. 41. B. 



Hab. Peru. A singular plant, with very closely-crowded pinnae and segments, the 

 alliance of which is evidently with T. lucens. 



]\f a i n rachis of the frond quite free or only very slightly winged towards 

 the apex. Sp. 58-77. 



t Fronds simply pinnate, pinnules not divided. Sp. 58-60. 



58. T. ccespitosum, Hk. ; rhizome wide-creeping, densely interlaced ; fr. sessile 

 or nearly so, 1-2 in. 1., Jin. br., simply pinnate ; pinnce concave, linear-oblong, 

 entire, about J in. 1. by \ lin. br., the under surface, or solitary costa only, 

 clothed with strong brown hairs ; texture rather rigid ; sori 1 only to a pinna, 

 terminal, the tube obovate-cuneate, quite immersed, the mouth spreading, with 

 two rounded lips. Hk. Syn. 1. p. 132. t. 40. B. Serpyllopsis, V. D. B. 



Hab. S. Chili, Cape Horn, and Falkland Islands. A very distinct plant, placed by 

 Van den Bosch in a genus by itself near Leptocionium. 



59. T. Javanicum, Blume ; caud. tufted, with numerous strong wiry roots .;.- st. 

 1-4 in. 1., wiry, erect, naked or villose ; fr. 2-8 in. L, 1-2 in. br., ovate-lanceolate, 

 acuminate, once fully pinnate ; lower pinnce often 1 in. 1., J in. br., oblong, 

 obtuse or acute, oblfquely cuneate at the base, finely toothed ; texture sub- 

 coriaceous ; veins numerous, close, central costa not clearly marked or con- 

 tinuous to the apex ; sori 1 to 4, placed in the axils of linear segments on the 

 upper side of the pinnse, tube free, the mouth broadly dilated but not two- 

 lipped ; recept. much exserted. Hk. Sp. 1. p. 130. Hk. $ Gr. Ic. Fil. t. 240.
