** Veinlets simple or with a reduced branchlet, which supports the torus. 



301. P. asplenifolium, L. Leaf pinnatisect, flaccid ■membranaceous, rusty-pilose 

 chiefly along the margin, shortly petioled : segments regularly alternate, horizontal, ovate- 

 oblong, blunt, broadly adnate, upward rounded and downward produced at the base, all 

 contiguous, most equal : veinlets apparently simple, but producing about the middle a 

 minute anterior branchlet, which supports the lateral sorus. — Plum. Fit. t. 102. A.

302. P. suspensum, L. Leaf pinnatisect, elastical-chartaceous, rusty-pilose at the 

 margin or glabrescent, supported by a slender, pendulous petiole ; segments regularly al- 

 ternate, nearly horizontal, shortly oblong-lanceolate, pointed or bluntish, broadly adnate at 

 the subequal base, entire, all contiguous, most equal : veinlets apparently simple, but often 

 producing about the middle a minute anterior branchlet : sori lateral on the latter (rarely 

 terminating a simple veinlet). — Plum. Fil. t. 87. dextr. P. laxifrons, Liebm. .', and P. 

 arcuatum, Moritz ! : a form with longer segments : in a variety (var. brachylobum, Gr. ;

 trees ; S. Vincent !, Guild. ; [Cuba ! and Mexico ! to Brazil !]. 



303. P. cultratum, W., Metten.! Leaf pinnatisect, elastical-membranaceous, rusty-

 entire or few-crenate-repaud, most distant by half their breadth, lowest shorter : veinlets 

 simple ; sori terminal.— Plum. Fil. t. 88. — Very variable in the size and form of the seg- 

 ments; H'-3" long, ascending or pendulous; segments 6" / -3'"(-8'"-2'") long, 2"'-3 

 broad. 



o. Segments ovate-oblong or shortly oblong-lanceolate, 6"'-3'" long. 



J3. brachyphyllum. Segments obliquely ovate or ovate-roundish, truncate at the lower, 

 rounded and usually crenate at the upper margin. — P. elasticum, Eat. {PL Wr. 1018). 



Hab. Jamaica !, Fd., Batter., Wils., on trees in the mountains (a, ff) ; [Cuba ! to Guade- 

 loupe ! ; Venezuela ! to Peru ! and Brazil ! ; tropical Africa to Mauritius]. 



304. P. pendulum, Sw. Leaf pinnatisect, elastical-chartaceous, subsessile, or shortly 

 petioled : segments regularly alternate, spreading, oblong, blunt, all contiguous at the 

 broadly adnate, obliquely subulate base, entire, most equal : veinlets simple ; sori terminal 

 or " lateral."— Schk. Crypt, t. 10. dextr. — 4"-12" long •. segments 14'" broad and as much 

 distant above the dilated base. 



a. Segments 8"'-4'" long.— P. pendulum, Metten. ex Sieb. Synops. 52: but the sori m 

 our specimens are terminal. P. venustum, PI. Carib. 



j3. jubiforme, Kaulf., Metten.! Low; segments 2"'-3'" long.— P. pendulum, ou>.

305. P. flabelliforme, Lam. Leaf pinnaiipar tit e, elastical-membranaceous, glabrous, 

 subsessile : segments regularly alternate, spreading, oblong or ovate, blunt, entire or crenate 

 chiefly at the upper margin, obliquely adnate and cohering by the decurrent & a *f> m0 \ 

 equal : veinlets simple; sori terminal.— S"-8" long ; segments 4"'-2"' long, 2"'-l' ' ° roaa - 

 — Hab. Dominica !, /wr., S. Vincent!, Guild.; [Portorico!; Guiana!; Brazil!]. 



306. P. moniliforme, Cav. Leaf pinnatisect, rigid-coriaceous, glabrous or glabres- 

 cent beneath, shortly petioled or subsessile : segments regularly alternate, nearly horizontal, 

 very shortly oblong, raunded or half-round, entire or crenate, revolute at the margin, 

 broadly adnate at the base, all contiguous, most equal : veinlets apparently simple ; * ort
