Note.—In the Botanical Register t. 14-12, has just appeared a Potentilla from Dr. Richardson, under the
name of P. Missourica of “ Hornemann;” but which I am quite unable to distinguish from Dr. Richardson’s
original specimens of P. Pennsylvanica.—H.

Hab. Throughout Canada, as far as Lake Winipeg. Dr. Richardson, Drummond, fi. and y. Lake
Huron. Dr. Todd.—What I take to be a small flowered variety of this is not uncommon in Upper Canada,
and this, I strongly suspect, is the A. parviflora of Ait., and probably the A. striata, imperfectly described
by Michaux, and which he says inhabits Canada; but he observes that the flowers are white. According to
my specimens from Mr. Elliott, his A. suaveolens is this var., but whether it be the same with that of Pursh,
I am not able to determine.

mountains in Vermont, and New Hampshire.

Hab. Canada. (Lintueus,) Douglas, MSS. Columbia River, on the North-West coast of America. Mr.
Menzies, Dr. Scouler. (5. At Port Wentworth. Mr. Menzies.—This is assuredly very nearly allied to our
Europaean S. officinalis; and was described by Linnaeus as a native of Canada, (from which country, however,
I have never seen a specimen,) and distinguished by its longer cylindrical spikes, and longer stamens.
In these characters, our plants from the North-West coast entirely agree; and I have a beautiful drawing,
made on the spot by Mr. Menzies, in which these distinctions are faithfully represented. The spike is a very
deep purple colour. At Fort Vancouver, on the Columbia, the leaves attain a length of twelve or fourteen
inches, and the stem a height of two feet. At Port Wentworth, they scarcely reach the height of a span.—
The style is single, according to Mr. Menzies’s figure; the stigma a globose tuft of hairs; and there are three
bracteas at the base of the calyx.
