several vows ; sori confined to the inner one, firm, immersed, so as to form very 

 distinct papilloe on tlie upper side. — Hi: Sp. 5. p. 31. — G. F. t. 41. 



Hab. Philppines and Malaccas. — This and the two preceding form the genus (Sc/icZ/o/ei^'s 

 of J. Smith. 



253. P. (Gonioph.) Korthahii, Mett. ; ?7«'^o?«c wide-creeping, the scales small, 

 reddish-brown, subulate, ciliated; st. S-H in. 1., smooth, reddish-brown; fr. 

 12-15 in. 1., 1 ft. br. ; jnnnce lax, spi-eading, sessile, 5-7 in. 1., 1-1 -3- in. br., 

 lanceolate-acuminate, tlie base cuneate, the edge sli;,ditly crenate ; texture sub- 

 coriaceous ; rachis and both sides quite naked ; areolae in 3-4 and the sori in 1-3 

 rows.— Mett. Fit. Ind. 2. p. 223. 



Hab. Sumatra, Korthals. — Differs from the three preceding by its multiserial sori. 

 P. Lnmpongcnsc, Zoll., may be the same, but the pinnae are said to be cordate or even 

 subauriculate at the base. 



254. P. (Gonioph.) attcnuatum, H. B. K. ; rhizome stout, the scales grey, 

 ovate-acuminate, spreading ; st. firm, erect, G-12 in. 1., glossy, naked ; fr. 1-2 

 ft. 1., often 1 ft. br., cut down to the rachis into numerous erecto-patent entire 

 pinnce 4-6 in. 1., |-| in. br., wliich are dilated at the base ; texture subcoriaceous ; 

 racJiis and both sides naked ; areolce in 3 or 4 rows ; sori slightly immersed in 

 1 or 2 rows. — Hk. Sp. 5. p. 24. {nou R. Br.). P. xiphophoron and gladiatum, 

 Kze. 



Hab. West Indies to Brazil and Ecuador. — Very near the next, with which Grisebach 

 imites it. The pinnae are closer, narrower, and dilated, sometimes confluent at the base, 

 and the sori mostly uniserial. 



255. P. (Gonioph.) neriifolium, Schk. ; rliizome stout, the scales grey, lan- 

 ceolate, spreading ; st. G-12 in. 1., firm, glossy ; fr. 1-3 ft. 1., 1 ft. or more br., 

 with an entire or slightly sinuated terminal innna 4-8 in. 1., -^-l^^ in. br., 

 and numerous similar ones on each side, wliich are narrowed at the base, the 

 lowest sometimes stalked ; texture coriaceous ; rachis and both sides naked ; veins 

 beneath prominent ; areolce in 2-6 rows between the midrib and edge, the 

 immersed sori 1-3 serial. — Hk. Sp. 5. p. 28. 



Hab. West Indies and Mexico to Brazil and Peru. — G. intermedium and acuminatum, 

 Fee, Fil. Ant. t. 18-19, appear to belong here. Apparently this is P. hrasiliense, Poir., 

 and if so, that name has priority. 



256. P. (Gonioph.) guatemalcnse, Hk. ; st. 6-12 in. 1., naked, stramineous ; 

 fr. 2-3 ft. 1., 1 ft. or more br., with an entire terminal pinna 6-8 in. 1., I-I5 in. 

 br., and several similar ones on each side, the upper ones narrowed but adnate 

 at the base ; texture subcoriaceous ; racJiis and both sides naked ; areola; in 

 series of 3-4, the large uniserial sori in the first or second row. — Hk. Sp. 5. p. 29. 

 Plilebodium insequale, Moore. 



Hab. Guatemala, SJcinncr. — In this there is occasionally a costal areola inside the one 

 that contains the sorus, but the fiwe veinlet which bears the latter is always simple. 



257. P. (Gonioph.) cordatum, Kze. ; rhizome stout, clothed with spreading 

 linear scales ; st. 1 ft. or more 1., strong, quite naked ; /)•. 1^-2 ft. 1., 8-10 in. 

 br. ; pinnce in numerous opposite pairs, 4-5 in. 1., |-1 in. br., the edge entire, the 

 point acute, the base very cordate ; texture coriaceous ; rachis and both sides 

 naked ; areolce irregular except the inner series ; sori in 1-2 rows, immersed. — 

 Mett. Poll/ p. p. 85.
