ones of Phhbodium, of which the first series is large and 

 soriferous, each areole including two veins with the glo- 

 bose sorus at their apex), the other areoles irregular, sori 

 rather large distant intermediate between the costse and the 

 margin. 



Hab. Tovar, Venezuela, Fendler, n. 247. — I cannot refer this to any described 

 species ; and probably Mr. Eaton could not do so either, nor satisfy himself that 

 it was new, and thus probably he was induced to omit it in his ' Fil. ^Ynghtianse 

 et Fendlerianae.' The habit and venation are tho>e of a small state of Pol. au- 

 renm, yet I cannot think it can be safely referred to that species. The stipes is 

 black, and the scales of the caudex are very peculiar. 



§ 6. GoNioPHLEBiUM. — Sori terminal on solitary veinlets within the costal series 

 of areoles, sometimes on those of one or more additional series. Goniophle- 

 bium, Bl. Marginaria, Pr., and Synammia, Pr., inpart. — Sp. 254-282. 

 * Fronds simple. Sp. 1. 



254. P. (Goniophlebium) glaucophyUum, Kze. ; caudex 

 long creeping or scandent thick as a goose-quill pruinose and 

 scaly with small peltate black scales with a brown margin, 

 stipites distant 2 inches to a span long testaceous glossy, 

 fronds firm subcoriaceo-membranaceous 4-8-10 inches long 

 1-2 inches wide broad-lanceolate finely acuminated entire, 

 primary veins costuliform parallel opposite, lowest veinlet free 

 axillary and soriferous, the rest connivent in opposite pairs 

 and excurrent into a free veinlet soriferous at the apex thus 

 forming a series of 7-10 areoles, sori consequently uniserial 

 between every pair of costules and multiserial longitudinally. 

 — Var. <x; fronds glauco-pruinose beneath, sori small. P. 

 glaucophyUum, Kze. in Schk. Fil. p. 227- t. 93 {excellent). — 

 Var. /3; fronds scarcely glaucous, sori small. — Var. 7; fronds 

 not glaucous, sori large.

 New Granada, Schlim,n. 125. — A well-marked species, yet presenting three va- 

 rieties as I conceive them to be. 



** Fronds pinnatifid. Sp. 255-268. 



255. P. (Goniophlebium) Californicum, Klfs. ; caudex 

 creeping paleaceous, stipes 3 inches to a span long testace- 

 ous, fronds 3-9 inches long 1-4-5 inches broad oblong or 

 ovate or even broad-ovate acuminate subpellucid deeply 

 nearly to the base pinnatifid, segments oblong or sublinear- 

 oblong mostly serrated acute or obtuse, terminal one rather
