 areoles, the veinlets free, sori suhovate. — Kaulf. Ea. Fil. p.

Hah. California, Chaminno, Sinclair, Beechei/, Barclay, Coulter, Lieut. Whip- 

 ple, lirackenriffr/e, Major Eaton, U.S.A. — Kaulfuss says, " P. vulgari simile, dif- 

 fert aiiteni quain niaxime, venulis sub margini laciiii<xanastoinosantil)us sorumqiie 

 ovatuiu includentibus." My P. infcrdium, which partakes of the two in its 

 venation Avealicns the characters of Qoniophlebiiun (alias Marginaria) as a 

 genus. 



256. P. (Goniophlebium) Scouleri, Hook, and Grev. ; 

 caudex creeping scaly, stipes 3-4 or more inches long 

 reddish brown, fronds 6 inches to nearly a foot long 3-G 

 inches wide thick-coriaceous broad-ovate deeply nearly to 

 the rachis pinnatifid, segments elliptical-oblong very obtuse 

 entire or obscurely serrated, terminal segment the longest, 

 veins anastomosing so as to form a single series of large 

 acute areoles extending nearly to the margin, sori very large 

 prominent subglobose, capsules very long stipitate. — Hook, 

 and Grev. Ic. Fil. t. 56. P. pachyphyllum. Herb. Eaton. 



Ilab. Straits of Juan de Fuca, N.W. America, Scolder, Barclay, Seemann. " Port 

 Orford," Ucrb. D. C. Eaton. — A most distinct and very little-known species. 

 My specimens vary with from 5-9 segments, but a sketch of a specimen from 

 Mr. Eaton, which I cannot doubt is identical witli this, is very much larger (10 

 inches long by G wide). Kunze (in Sill. Journal, vi. 1848, p. 82) says P. Scoiileri, 

 IT. and Gr., is incorrectly united with the very distinct P. Californlcum, Klfs., 

 in ' Hook. Fl. Bor. Am.' ; and Brackenridge says, " we find the P. Scouleri 

 referred to P. Califm'nicum, Klfs. :" but these authors surely cannot have seen 

 the Fl. Bor. Americana, where, I regret to say, by inadvertence, the plant is 

 omitted. 



257' P- (Goniophlebium) pubescens. Hook, and Grev.; 

 caudex creeping tortuous ferrugineo-paleaceous, stipes 4 

 inches to a span long, fronds firm-membranaceous subglan- 

 duloso-pubescent 6-15 inches long 2-4 inches wide from a 

 rather l)r()ad base ovato-oblong acuminate ])innatifid nearlv 

 to the rachis pinnated below, segments and pinna; horizontal 

 often opposite elongato-oblong acute or obtusely acuminate 

 entire or the lower ones and pinnic especiallv more or less 

 deeply but irregularly pinnatifid, veins anastomosing .so as to 

 form a single costal series of large areoles, sori rathor small.
