-f in. br., ovate-lanceolate or linear-oblong, bipinnatifid ; pinnae reaching down 

 very nearly tothe 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 veins of the pinnse usually once 

 branched ; sori 1 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 

 Ragatelus of Presl.

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

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

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

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

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



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

 t alliance of which is evidently with T. lucens. 



** Main rachis of the frond quite free or only very slightly winged towards 

 the apex. Sp. 58-77.

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

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

 entire, about \ 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,

 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
