133. P. exiguum, Griseb. ; st. tufted, thread-like, very short, naked ; fr. 

 pendulous, 6-24 in. L, 2 lin. br. ; pinnae ^-1 lin. 1., ^ lin. br., half-ovate, blunt, 

 entire or with a single crenation on the upper side, distant, but the base broadly 

 dilated on both sides ; texture subcoriaceous ; both sides naked ; veins and sori 

 1 to each pinna, the former forked. Griseb. Fl. Brit. W. Ind.p. 701. 



Hab. Jamaica, Purdie. 



134. P. trichomanoides, Swz. ; st. densely tufted, short, clothed with soft 

 spreading deciduous hairs ; fr. 3-6 in. ]., 2-4 lin. br., cut down to the rachis into 

 close linear-oblong blunt pinnae under 1 lin. br. ; rachis wiry, ebeneous ; texture 

 subcoriaceous, the surfaces naked or slightly clothed with soft hairs ; veins and 

 sori 1 in each pinna, the former forked, the latter near the base. Hk. Sp. 4. 

 p. 178. j3, P. truncicola, Klotzsch ; lobes not reaching quite down to the rachis, 

 soft hairs more copious. Hk. Sp. 4. I. c. 



Hab. Cuba to Brazil and Ecuador ; Juan Fernandez, Ascension Island, Malacca, 

 Sikkim. 



135. P. flabelliforme, Lam. ; st. tufted, short, fringed with long soft hairs ; 

 fr. flaccid, 4-12 in. 1., f-jr in. br., cut down throughout nearly or quite to the 



rachis into entire or slightly crenate blunt pinnae \-\\ lin. br., which are 

 decurrent at the base ; texture papyraceo-herbaceous ; rachis and both sides 

 naked or with a few long soft hairs ; sori large, 1-3 to a pinna, terminal on the 

 short simple veinlets. Hie. Sp. 4. p. 187. 



- Hab. Columbia to Peru. Distinguished in the group by its flaccid habit, slender black 

 filiform rachis, and few sori. 



136. P. subtile, Kunze ; st. tufted, slender, very short ; fr. flaccid, 3-4 in. l. 

 2-4 lin. br., ligulate, narrowed gradually towards both ends, cut down to the 

 rachis throughout into close entire blunt pinnce ^-f lin. br. ; texture papyraceo- 

 herbaceous ; rachis black, like both sides thinly clothed with long soft hairs ; 

 sori 3-6 to a pinna, terminating the short veinlets. Hk. Sp. 4. p. 187. t. 275. A. 



Hab. Venezuela to Peru. Lobes narrower and closer than in the last, and texture 

 almost that of a thin Adiantum. P. subscabrum, Hk. Sp. 4. p. 183. t. 274. A. is appa- 

 rently this ; but it is not the plant of Klotzsch. 



137. P. delicatulum, M. & G. ; rhizome wide-creeping, slender ; st. tufted, 

 wiry, 1-2 in. 1., densely clothed with long soft hairs ; fr. 4-6 in. 1., \ in. br., cut 

 down to the rachis into close blunt entire pinnce 1-1^ lin. br., the lower ones 

 broader and shorter ; texture subcoriaceous ; veinlets simple ; both sides thinly 

 clothed with long soft hairs ; sori copious, subimmersed, 6-8 to a pinna. Hk. 

 Sp. 4. p. 184. 



Hab. Mexico to Ecuador. 



. P. peruvianum, Desv. ; rhizome creeping, fibrillose ; st. 1-2 in. ]., slender, 

 clothed with soft spreading hairs ; fr. 3-4 in. L, -f in. br., cut down to

 erect, 



the rachis into oblong-triangular blunt entire pinnce |"in. br. ; texture sub- 

 coriaceous ; both sides nearly naked ; veinlets immersed, simple ; sori rather 

 large, 2-4 to a pinna. Hk. Sp. 4. p. 186. P. anfractuosum, Kze. 



Hab. Venezuela and Peru. This comes very near the next species. P. monticola, 

 Klotzsch, is probably a reduced form. It is described as caespitose ; but in our specimen 

 the rhizome is slender and greatly elongated, with the fronds 2-3 in. distant from one 

 another. 



139. P. parvulum., Bory ; rhizome stout, short-creeping, clothed with linear 

 scales ; fr. 4-6 in. 1., f in. br., tapering gradually downwards into a very short
