 texture papyraceo-herbaceous ; rachis and both surfaces naked ; veins black, 

 distinct, once forked ; sori in rows near the edge, deeply immersed, the cavity

 reduced ; texture coriaceous ; both surfaces naked ; veinlets hidden ; sori large, in 

 marginal rows. 



Hab. S. Brazil, Gardner, 128 ; Venezuela, Fendler, 216. Most like P. suspensum in 

 cutting, but suberect, and the texture so rigid that the frond will scarcely adhere to 

 paper.

 in. 1., rigid, erect, blackish, glossy ; fr. 12-18 in. 1., 2-3 in. br., cut down into 

 close horizontal entire blunt pinnce 1-1^ lin. br., dilated at the base ; texture 

 papyraceo-herbaceous ; rachis rigid, black, scaly throughout on the lower side ; 

 midrib black ; veinlets obscure ; sori small, in 2 long rows. Hk. Sp. 4. p. 199. 



Hab. Cuba and Mexico to Brazil. Very near P. taxifolium, but a coarser plant, with 

 less distinct venation. 



177. P. taxifolium, L. ; rhizome stout, scaly ; st. subtufted, 2-4 in. ]., erect, 

 rigid, clothed with soft spreading hairs ; fr. 6-12 in. or more 1., 1^-3 in. br., cut 

 down to the rachis into close entire or slightly crenated blunt horizontal pinnce 

 1^-2 lin. br., the lower ones distant and much reduced ; texture papyraceo- 

 herbaceous or subcoriaceous ; rachis naked or villose ; both sides naked ; veinlets 

 simple, very distinct, with the sori terminal upon them. P. Plumula, H. B. K. 

 Hk. Sp. 4. p. 200. 



Hab. Mexico and West Indies to Peru and South Brazil. Well distinguished by its 

 finely-cut pectinate habit and simple oblique usually distinctly-marked veiulets, with the 

 sori terminal upon them. P. ferrugineum (M. & G.), Hk. Sp. 4. p. 182. and P. apicula- 

 tum (Kze.), Hk. 1. c. p. 185. both seem small forms of this, rather thicker in texture than 

 usual. P. L'Herminieri, Fee, Fil. Ant. t. 12. belongs here. 



178. P. recurvatum, Kaulf. ; rhizome creeping, the scales ovate-lanceolate, 

 bright-ferruginous ; st. 3-6 in. 1., firm, erect ; fr. 1-3 ft. 1., 4-6 in. br., cut down 

 to the rachis into close entire acuminate pinnce fa-% in. br., the lower ones 

 quite distinct, not smaller than the others ; texture subcoriaceous ; rachis finely 

 pubescent ; veins obscure, forked ; sori in a single medial line. Mett. Polyp,
