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.

This belongs to that division of the genus with orbicular aud peltate involucres, and to the same groupe
with A . auriailatum, from which it is readily distinguished by the above characters. Mr. Menzies gathered
It m the Voyage with Vancouver, and Rlr. Douglas aud 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 rachibusque
paleaceis, soris subcostalibus, involucris rotimdato-reniformibus sinu profundo.—Kaulf.

This had been previously observed by Chamisso to be a native of California.
1. Azolla microphylla; frondibus orbiculatis semipinnatis pinnis trilobis, foliolis imbricatis
adpressis minutis. 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.

The venerable and indefatigable Menzies was the first to discover this singular Lichen, on the North-
