as lat. 30°. Shores and Islands of the Arctic Sea, ( Captain Sir J. Franklin and Captain Sir E. Parry,)
but much less frequent than D. integrifolia, from which it may always and readily be distinguished.

Richardson, Parry, Sabine, Sfc. Extending westward to Behring’s Straits. Chamisso, Lay and Collie in
Captain Beecherfs Collection. Rocky Mountains, between lat. 52° and 56°, especially on the more elevated
ridges. Drummond.—Leaves much smoother (less impressed with veins), and the whole plant far less glandular
than the preceding species. It retains its character for years in cultivation.

the mouth of the River Bear Lake on the shores of the Arctic Sea in lat. 68°. Dr. Richardson. Gravelly
battures of alpine rivers, among the Rocky Mountains. Drummond.—This highly beautiful and little known
plant is distinguished from the other species of Dryas no less by the colour of its flowers than by the form
of its calycine segments.

S. Fort Vancouver, on the Columbia.—My var. 0, entirely agrees with what is cultivated in our gardens
as the f t macrophyUum, and sufficiently so with the description of authors; but 1 do not find that it differs
from the G. strictum, (which is indeed a most variable plant,) except in size.

Hab. Canada. Michaux, Pursh. Lake Huron. Ur. Todd.—I have not myself seen specimens from
any other- part of the British Possessions than Lake Huron; but this is a frequent plant in the United States.
The G. album, of which I have fine specimens from Dr. Torrey, cannot be distinguished from G. Virginianum •
the leaves are frequently trifoiiolatc and pinnate from the same root. Professor Bigelow observes that there
are intermediate states between the two species.

Hab. On the banks of the Kooskooskye River, North-West America. Lewis, (ex Pursh.)—The flowers
are said by Pursh, to whom alone this plant seems to have been known, to resemble those of the preceding
species. ■ ^
