Filites-I 
CALIFORNIA.— SUPPLEMENT. 
405 
Nothing has surprised us more than finding that a species of a Genus, hitherto considered as exclusively 
inhabiting the Polynesian islands, should be detected in the northern continent of the New World. The 
collection contains several specimens; and though it is barely possible that these may have been accidentally 
mixed up with the herbarium ; yet seeing that every other plant is unquestionably Californian, or from the 
immediately adjacent territories, and that Mr Douglas had no intercourse with New Holland, where alone the 
species has hitherto been found, we are bound to believe it a Californian plant, and to introduce it as such. 
The specimens are very perfect, and some of them in fructification.

1. Polypodium (Marginaria) Californicum, Kaulf. — Hook, et Arn. supra^ p . 161. — Mar- 
ginaria, Presl. 
San Francisco. Dr Sinclair. — Presl refers this to his genus Marginaria, whose essential character is to have 
the upper veinlets uniting with the nearest opposite ones, so as to form hexagonal areolae, in which is situated 
the sorus at the extremity of a lower veinlet. But in this plant the veinlets are sometimes entirely free, and 
when the union does take place, it is only near the margin. 
2. P. (Eupolypodium) intermedium; fronde lato-lanceolata mernbranacea pellucida fere 
ad rachin pinnatifida, laciniis oblongis obtusis aequilatis serratis glabris, venulis distinctis 
liberis rarissime sub margine anastomosantibus, soris ovalibus solitariis. 
San Francisco. Dr Sinclair. — Allied to the preceding P. Californicum, and to P. vulgar c; from the 
former it differs in the almost entirely free veinlets, from the latter in its oblong or oval sori, and from both 
in the pellucid, not opaque frond, and in the laciniag becoming smaller at the base. Although this must be 
referred to the true Polypodium of Presl, yet the veinlets do occasionally unite so as to form an elongated 
and somewhat hexagonal areola in which a veinlet, terminated by a sorus, is included.
