more herbaceona texture, and larger almost constantly nniserial soii. The Mexican 

 P. appendictdatum, Klotzsch (Hi. Fil. Ex. t. 87), non WalUch, ia apparenUy a foim of this 

 more delicate in textnre, with the Teins and rachis tinged with bright-red. 



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

 squaiTose, OTate-acniniiiate, dark-brown ; St. 4-6 in. 1., firm, erect, stramineous ; 

 Jr. 8-12 in. 1., 4-5 in. br., cut down to the rachis into close bluntish enthepimKB 

 |-in. br., slightly dilated at the base; feature herbaceous; both sides finely 

 villose ; sori prominent, uniseiial. — Ht. Sp. 5. p. 21. 



Hab. Venezuela. — Very near the preceding. 



242. P. (Cronioph.) Ck&harince, F. & L. ; rhizome wide-creeping, the scales 

 spreading, dark-brown, ovate-acuminate ; si. 4-6 in. 1., erect, naked, glossy ; fr. 

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

 pintuB If-S in. 1., J-^ in. br., the lowest pair shorter and deflexed ; texture sub- 

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

 generally two areolse between the edge and midrib ; sori large, in single rows 

 close to the midrib. — Wk. Sp. 5. p. 20 (not J. Sm.). 



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



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

 black in the centre, with a sCi.iiose border ; st. 4-6 in. 1., sometimes ebeneous ; 

 Jr. 12-18 in. 1., 4-6 in. br. ; pinnce close, 2-3 in. 1., §-^ 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. — Hk. Sp. 5. p. 21. — /3, 

 P. latipen, L. & F. t. 10 ; larger, as coriaceous but less rigid ; pinrtm much 

 dilated en both sides at the base ; veins less distinct ; scales o.vat«, dense, dull- 

 brown. — P. Catherinae, 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. daxyplemon, and Falcaria (Kze.) and Icetmn (Raddi). P. pectinatum (J. Sm.) 

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

 ferruginous scales and constantly uniserial sori. P, pwnctvZaium, Hk. Ic. t. 720 {P. Cala- 

 guala, V6e), resembles this in its slender pectinate habit and uniserial sori, but is more 

 rigid in texture. 



244. P. (Gonioph.) eleutherophlebium, 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 pinncB 2 in. 1., r in. br., with blunt rounded 

 lobes ; texture coriaceous ; sori large, nniserial. — Mett. Polyp, p. 75. 



Hab. Venezuela, Pvmck and Sdhlim, 1102. — We have not seen this, and are indebted 

 to Mettenius for the description.

245. P. (Gonioph.) chacapoyense, Hk. ; st. 6-8 in. 1., firm, naked, reddish ; fr. 

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

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

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

 row.— -.HS, Sp. 5. p. 29. t. 281.
