deflexa laciniis ovatis obtusis subtus flavo-farinosis. Kaulf. Enum, Fil. p. 73. Hook, et Grev. 
Ic. Fil. t. 315. 
This has likewise been gathered by Mr. Douglas, on the elevated grounds between the “ Grand Rapids” 
and the “ Kettle Falls” of the Columbia, and upon Mount Hood to the South of that River. 
1. Aspidium munitum; frondibus pinnatis, pinnis lineari-lanceolatis spinoso-acuininatis 
subfalcatis basi sursum aiiriculatis invicronato-serratis, serraturis subappressis rarissime 
bidentatis, stipite rachique subtus et basin versus paleaceis, soris solitariis. — Kaulf. Enum. 
Fil. p. 230. 
This belongs to that division of the genus with orbicular and peltate involucres, and to the same groupe 
with A. auriculatum, from which it is readily distinguished by the above characters. Mr. Menzies gathered 
it in the Voyage with Vancouver, and Mr. Douglas and Dr. Scouler about the mouth of the Columbia. 
2. Aspidium argutum ; frondibus bipinnatis, pinnulis oblongis obtusis apice mucronato- 
serratis, inferioribus longioribus pinnatifidis laciniis mucronato-serratis, stipite racliibusque 
paleaceis, soris subcostalibus, involucris rotundato-reniformibus sinu profundo. — Kaulf. 
Enum. Fil. p. 242. 
The excellent Kaulfuss compares the fronds and pinnules of this plant to Aspidium Filix 7nas., but to us 
they appear rather to approach those of Asplenium Filix fcemina, from which, however, the fructifications 
abundantly distinguish it. 
1. Woodwardia ra(ifca??s; frondibus pinnatis, pinnis profunde pinnatifidis laciniis oblongo- 
acuminatis subfalcatis subrepandis argute serrulatis. — Willd. Sp. PI. v. b. p. 418. Kaulf 
Enum. Fil. p. 1 62. 
This had been previously observed by Chamisso to be a native of California. 
1. Azolla microphylla ; frondibus orbiculatis semipinnatis pinnis trilobis, foliolis imbricatis 
adpressis ininutis. Kaulf Enum. Fil. p. 273. 
Kaulfuss has well observed that the species of Azolla are very difficult to be distinguished in a dry state. 
Whether the present ought to be separated or not from the A. Magellanica, it is certain that it is the plant 
of Kaulfuss now quoted, whose specimens were gathered in California by Chamisso.
