Hab. Near Cumberland House, lat. 54°. Dr. Richardson. North-West Coast of America. Mr. Menzies.
—Only two specimens of this are in Dr. Richardson’s collection. The true D. longifolia, with seeds destitute
of arillus, and with shorter leaves than the present, I have received from New York and near Boston;
but I have not seen specimens from Canada, where it is yet very likely to be found.

midis, scapis radicatis 1-3-floris, calycibus glabris, seminibus exarillatis laevibus., (Tab.

3-valvis. Semina ovali-oblonga, cxarillata, lsevia, nigra.
Hab. Lake Simcoe, in Upper Canada. Mr. Goldie. It was found sparingly in fruit also in Upper Canada,
as well as plentifully in a swamp near Jasper’s Lake in the Rocky Mountains, by Mr. Drummond.—It was at
my suggestion that Mr. Goldie, on his return from his travels in Canada, published the present plant as a new
species in the Journal above quoted. The form of the leaf alone did appear to me quite decisive of a specific
difference ; but the American Botanists, and especially Dr. Torrey, entertained a different opinion, though I am
not aware that the plant is at all known to them; and the able Botanist just mentioned has been disposed to
unite it with the D. longifolia. It was therefore peculiarly gratifying to me to find amongst Mr. Drummond’s
rich collection many specimens gathered in the Rocky Mountains, and all possessing the characters
detailed by Mr. Goldie, under his D. linearis. The name is singularly applicable; for from the blunt apex
nearly to the very base of the limb or blade, it retains the same width. It must not be confounded with
the American D. filiformis (tenuifolia, Willd. and Muhl.); which has the leaves vastly longer and filiform,
and which Dr. Torrey aptly compares to the rare and beautiful DrosophyUum lusitanicum.

H ab. North America. Banks. Herb, (in D e Cand.) Sandy banks formed by the floods in the rivers
among the Rocky Mountains, between lat. 52® and 56®. Drummond.—Numerous specimens of this pretty
Pamassia exist in Mr. Drummond’s portion of the collection, and all so constant to their characters, that I
have little hesitation in considering it a good species, and I think too it is the P. parviflora of De Candolle.
It is remarkable for its slenderness, for the root-leaves being ovate, that of the stem still narrower, and so
small as, in most instances, to represent a true bractea. Whether the P. ovata p>. Belvisii of De Candolle,
should be considered the same, as I rather suspect, or not, I have no materials for determining. The flower
of our plant is considerably smaller than that of P. palustris, so as well to merit the name of parviflora.

H ab. About Quebec, Mrs. Percival, and Lake Huron, Dr. Todd: which are perhaps the most northern
limits of this fine plant, as well as the most western, at least in that latitude.—The leaves are more coriaceous,
and paler beneath than any other species with which I am acquainted : their shape is either broadly
ovate or elliptical ; but they may vary in form, and I suspect the P . grandifolia of Beauvois and De Candolle
can hardly be considered different. The P . asarifolia of Ventenat I have never seen, nor do the Ammran
Botanists themselves appear to be acquainted with it.
