add, too, the acutifolia of Ledebour, which is a perennial plant, with a thick tap-root.—It has perhaps a
claim to be considered as American; at least Gmelin’s plant is said to be found at Mount St. Elias, and in
the islands between Asia and North America.

Hab. North-West coast of America. A. Menzies, Esq. in Herb, nostr.—In the vallies of the Rocky
Mountains, common. Douglas.—This is the smallest species of the whole genus, and in regard to its
character, it seems to hold the same relation to C. alsinoides as the C. parvifiora does to C. perfoliata;
being essentially distinguished by its exceedingly narrow leayes.

Hab. Canada. Linn.—I have not seen specimens of this from Canada: but being of frequent occurrence in
the adjoining districts of the United States, it is in all probability, independent of the authority of T.inna*n<^ a
Canadian plant; though perhaps confined to the southern parts.—Torrey, and I think with justice, unites the
A. capillacea of Nuttall with this, as a glabrous variety.

Hab. Dry banks of the north branch of the Saskatchawan: between Carlton House and Edmonton
House: lat. 53°. North. Drummond.—Mr. Nuttall, who has admirably characterised this species of Paronychia,
discovered it on the highest bills of the Missouri, near Fort Mandan, 4° or 5° south of the country
where Mr. Drummond gathered i t : it is therefore probably not uncommon on the eastern slope of the
Rocky Mountains.—Professor De Candolle has not rightly understood Mr. NuttalTs expression, “ internal
points of the calyx arched, external capillary attenuated.” It is not “ calycis lobis internis arcuatis extends
attenuatis,” as in the Prodromus; whence our learned friend has been led to suppose that the segments were
unequal, and to express an opinion that the species should belong to the third section, which is so characterised
: whereas the segments are perfectly equal.
