30 POLYPODIUM, § GONIOPHLEBIUM. 



276. P. (Gonioplilebium) Surrucuchense, Hook. ; caudex 

 stout creeping paleaceous with large lanceolate glossy reticu- 

 lated long acuminated scales, stipites 4-5 inches to a foot 

 long brown-stramineous, fronds firm-coriaceous bright-green 

 paler beneath glaljrous G inches to 2 feet and more long 4 

 inches to a foot and more wide broad-ovate long-caudato- 

 acuminate pinnated to the very apex (terminal pinna much 

 elongated and long-petioled), pinnae distant 7-8 to 27, lateral 

 ones sessile 3-6 inches and more long \-% of an inch liroad 

 from a cuneate sessile base linear-oblong much and finely 

 acuminate entire or subsinuate, venation always pellucid, 

 veins forming a single costal series of fertile areoles, the rest 

 of the \ einlets free, sori very orbiculari-globose ranged close 

 to the costa. — Hook. Ic. PL t. 69 {arm. 1837), smull speci- 

 meti. P. andinum, Karst. FL Columb. p. 171. t. 85, very 

 good {ann. 1861). 



Hab. Tropical America : Ecuador, Surrucuchu, Jameson ,- Tungiiragua, on 

 trees, Spruce, n. 5241, and Bancs, n. 5238 ; Bogota, Karslen ; Venezuela, Fend- 

 ler, n. 413 ; Jamaica, 7l/r. IViles ; Dominica, Dr. Imrai/, n. 112.— My first know- 

 ledge of this handsome species, of a bright-green colour, with pellucid veins and 

 large ferruginous sori, was derived from a small specimen sent by Professor Jame- 

 son ; since that I have received it from other regions of tropical America, yet I 

 can find no description to accord with it till very recently, 18G1, when a fine 

 figure ap])ears, among many other long-described but supposed new species of 

 Ferns, under the name of P. andinum, Karst. 



277' P- (Goniophlebium) plectolepis, Hook.; "caudex 

 creeping clothed with ferruginous lanceolate ciliated scales, 

 stipites 15 inches long glabrescent glossy brown, fronds co- 

 riaceous 4 feet long 1 foot wide elongato-lanceolate pinnate, 

 pinnae alternate patulous subopposite below horizontal dis- 

 tant 6-7 inches long decreasing towards the base \-\^ of an 

 inch wide linear-lanceolate acute sessile obliquely and broadly 

 cuneate at the base, the margin rotundato-crenate, costa pro- 

 minent on both sides, veins obscure five- or six-furcate, 

 veinlets forming a series of elongato-pentagonal areoles, sori 

 near the costa rather large ferrugineous uniseriate, rachis 

 costa and pinnae on both sides finely pubescent, down easily 

 deciduous, rachis bisulcate in front rounded at the back.'^

Hab. Totutla, Mexico, Liebmann. — My specimens from Liebmann well accord 

 with his description. In habit it perhaps comes nearest to our P. Surrucuchense, 

 but it attains a much larger size, has less coriaceous pinnse, stiongly serrated and 

 less acuminated, the venation is difif'cient, and the veins very opaque, and it wants 

 the long, terminal, distinct pctiolated pinn.c of that species.
