more herbaceous texture, and larger almost constantly uniserial sori. The Mexican 

 P. appendiculatum, Klotzsch (Hk. ¥i\. Ex. t. 87), non Wallich, is apparently a form of this 

 more delicate in texture, with the veins and rachis tinged with bright-red. 



241. P. (Gonioph.) lasiopus, Klotzsch; rhizome stout, the scales dense, 

 squarrose, ovate-acuminate, dark-brown ; st. 4-G in. 1., firm, erect, stramineous ; 



fr. 8-12 in. I., 4-5 in. br., cut down to the rachis into close bluntish eniiva pinnw 

 \-\n. br., slightly dilated at the base ; texture herbaceous ; both sides finely 

 villose ; sori prominent, uniserial. — Rk. Sp. 5. p. 21. 



Hab. Venezuela. — Very near the preceding. 



242. P. (Gonioph.) Catliaritice, F. & L. ; rhizome wide-creeping^, the scale? 

 spreading, dark-brown, ovate-acuminate ; st. 4-G in. 1., erect, naked, glossy ; fr, 

 6-12 in. 1., 3-5 in. br., cut down to the rachis into close blunt spreading subentire 

 pinnce 1^-3 in. 1., ^-^ in. br., the lowest pair shorter and defiexed ; texture sub- 

 coriaceous, colour dark-green ; both sides naked ; main veins § in. apart, with 

 generally tw^o areolae between the edge and midrib ; sori large, in single rows 

 close to the midrib. — HI: Sp. 5. p. 20 {not J. Sm.), 



Hab. Brazil. — Very doubtfully distinct from the next species. 



243. P. (Gonioph.) loriceum, L. ; rhizome stout, wide-creeping, the scales 

 black in the centre, with a scariose border ; st. 4-G in. 1., sometimes ebeneous ; 

 fr. 12-18 in. L, 4-6 in. br. ; pinnce close, 2-3 in. 1., f-^ in. br., subentire, some- 

 times falcate, dilated at the base on the upper side ; texture subcoriaceous ; 

 rachis and both sides usually naked ; veins very distinct, the areolae generally in 

 two distinct rows, with the small sori often in both. — Ilk. Sp. 5. p. 21. — (i, 

 P. latipes, L. & F. t. 10 ; larger, as coriaceous but less rigid ; 2)in7ice much 

 dilated on both sides at the base ; veins less distinct ; scales ovate, dense, dull- 

 brown. — P. Catherina?, J. Sm. {not L. & F.) P. harpeodes and vacillans, Link 

 {fide Moore'). 



Hab. Mexico and West Indies to Brazil and Chili. — From this we cannot distinguish 

 clearly P. dasypleuron and Falcaiia (Kze.) and ketum (Raddi). P. pectinatum (J. Sm.) 

 is smaller and more delicate, with close narrow acute pinnte, densely fibrillose bright 

 ferruginous scales and constantly uniserial sori. P. punctulatum, Hk. Ic. t. 720 (P. Cala- 

 guala, Fee), resembles this in its slender pectinate habit and uniserial sori, but is more 

 rigid in texture. 



244. P. (Gonioph.) eleuthcrophlcbium, Mett. ; rhizome creeping, the scales 

 dense, ovate-lanceolate, brown ; st. 4 in. 1. ; fr. 7 in. 1., 4 in. br., ovate-deltoid, 

 cut down nearly to the rachis above, quite below, into linear-oblong obtuse 

 crenate or irregularly pinnatifid pinnai 2 in. 1., j in. br., with blunt rounded 

 lobes ; texture coriaceous ; sori large, uniserial. — Mctt. Polyp, p. 75. 



Hab. Venezuela, Funclc and Scldim, 1102. — We have not seen this, and are indebted 

 to Mettenius for the description. 



B. Most ofthepnnnce distinctly separated at the base. Sp. 245-260. 



245. P. (Gonioph.) chacapm/ense, Hk. ; st. G-8 in. 1., firm, naked, reddish ; //•. 

 1 ft. 1., 2-3 in. br., with a linear entire terminal pinna 2-3 in. 1., j in. br., and 

 several smaller blunt close erecto-patent similar ones on each side ; texture sub- 

 coriaceous ; rachis and under side slightly villose ; areolce and veins in a single 

 row.— Hk. Sp. 5. ;a 29. t. 281. 



Hab. Peru, Matthews, 3279. 



240. P. (Gonioph.) surructichense. Ilk. ; rhizome stout, densely clothed with 

 spreading grey lanceolate scales ; si. G-12 in. 1., firm, naked, glossy ; fr. 1-2 ft.
