correctly united the S. Canadensis of Linnaeus, with S. Marylandica. I do not see the necessity even of
making a variety of it; and the Linnsean character is equally applicable to the one as to the other plant.

H ab. North-West coast of America. A. Menzies, Esq. On the banks of the Columbia, in dry sandy
soils. Dr. Scouler. Douglas.—This is a very distinct species from the S. Marylandica, but very nearly
allied to the S. Liberia of Chamisso in Linmea, v. 1. p. 253, a native of Chili. If it should prove to be the
same, it has then a very extensive geographical range; for that author states it to be the “ S, Marylandica,
of Willdenow’s Herbarium, an Humboldtian plant, found at Caripe.” The Naturalists of Captain
Beechey’s Voyage, gathered our plant in California.

Hab. North-West coast of America. A. Menzies, Esq.—This plant has very much the appearance of
the genus Arctopus, the leaves and segments of the leaves being curiously pinnatifid at the margin, with
crowded, acuminated, unequal teeth. The umbel is nearly simple, and scarcely rises above the foliage.
The root is fusiform.

Hab'. Moist soils on the plains of the Multnomak River. Douglas.—Of this I possess but one, and that
an imperfect specimen; but sufficient to show that the species is very different from any with which I am
acquainted, and from any which I find described in books. The petioles are very long, 4—6 inches in length,
linear, dilated into a sheath at the base, slender, above gradually passing into a lanceolate blade with parallel
nerves. The heads are quite spinous with the long rigid involucres and palese, which much exceed the
flowers in length. The calyx is large, with leafy sepals. The germen covered with white, ovate, acute,
somewhat imbricated minute vesicles.
