48. POLYPODIUM, GONIOPHLEDIUM. 345 



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

 distinct papillae on the upper side. Hk. Sp. 5. p. 31. G. F. t. 41. 



Hab. Philppines and Malaccas. This and the two preceding form the genus Schdlolqtis 

 of J. Smith. 



253. P. (Gonioph.) Korthalsii, Mett. ; rhizome wide-creeping, the scales small, 

 reddish-brown, subulate, ciliated ; st. 5-6 in. 1., smooth, reddish-brown ; fr. 

 12-15 in. 1., 1 ft. br. ; pinnce lax, spreading, sessile, 5-7 in. 1., 1-1^ in. br., 

 lanceolate-acuminate, the base cuneate, the edge slightly crenate ; texture sub- 

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

 rows. Mett. Fil. Incl. 2. p. 223. 



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

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

 subauriculate at the base. 



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

 ovate-acuminate, spreading ; st. firm, erect, 6-12 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., which are dilated at the base ; texture subcoriaceous ; 

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

 1 or 2 rows. Hk. Sp. 5. p. 24. (non R. Br.*). P. xiphophoron and gladiatum, 

 Kze. 



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

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

 and the sori mostly uniserial. 



255. P. (Gonioph.) neriifolitim, Schk. ; rhizome stout, the scales grey, lan- 

 ceolate, spreading ; st. 6-12 in. 1., firm, glossy ; fr. 1-3 ft. 1., 1 ft. or more br., 

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

 and numerous similar ones on each side, which 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, 

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

 and if so, that name has priority. 



256. P. (Gonioph.) guatemalense, 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., 1-1 in- 

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



'at the base ; texture subcoriaceous ; rachis and both sides naked ; areolce in 

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

 Phlebodium insequale, Moore. 



Hab. Guatemala, Skinner. In this there is occasionally a costal areole inside the one 

 that contains the sorus, but the free 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; fr. 1^-2 ft. 1., 8-10 in. 

 br. ; pinnce in numerous opposite pairs, 4-5 in. 1., f-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. Polyp, p. 85. 



Hab. Peru. 



258. P. (Gonioph.) adnatum, Kunze ; st. 6-12 in. 1., glossy, naked ; fr. l|-3 

 ft. 1., 1 ft. br., with an entire oblong-lanceolate terminal pinna 6-9 in. 1., l-J-2 in.
