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

 simple ; sori terminal. — Plum. Fit. t. 88. — ^Very variable in the size knd form of the seg- 

 ments; li'-3" long, ascending or pendulous; segments 6"'-3"'(-8*^2"') long, 2"'-3"' 

 broad.

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

 rounded and usually crenate at the upper margin. — P. elasticum. Fat. {Fl. Wr. 1018).

 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 r veinlets simple ; sori terminal 

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

 distant above the dilated base. 



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

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



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

 equal : veinlets simple; sori, terminal. — 3"-8" long ; segments 4"'-2"' long, 2"'-l"' broad. 

 — Hab. Dominica !, /mr., S.Vincent!, Gtiild.;' [Portorico!; Guiana! ; Brazil!].
