are in perfection.* The two are very nearly allied in habit; but St. nivalis may always be known by the
deep brown and very numerous long hairs which clothe its calyx and peduncle. My specimens of R. fri-
gidus, given me by Mr. Prescott, from the Altaic Mountains, scarcely differ from this species, especially the
var. A The leaves are wedge-shaped, crenato-lobate; the petals more or less obtusely emarginate at the
extremity, and the nerves are more frequently anastomosing than in R. nivalis. But again, one of my Spitsbergen
specimens has notched petals, and I fear the peculiarity of the nervation of the petals is not constant.
Hence, I should be much inclined to unite them.

snow, on the borders of streams upon the Rocky Mountains, lat. 52° to 56°: Drummond.—Schlechtendal
has admirably described this species; and his figure differs in nothing from the greater number of our Rocky
Mountain specimens, except in being larger and more luxuriant in all its parts. The var. /3. above mentioned
is indeed as large as the specimens in Schlechtendal’s figure, but the petals are abortive. The author
of the “ Animadversationes” observes that it differs from R. nivalis in all the leaves being constantly ciliated,
(so they are in our R. nivalis,) in those of the root being always tripartite, with the divisions constantly
lobed, in the calyx always sparingly clothed with fulvous hairs, and the carpels having the styles shorter
than themselves. Mr. Drummond’s specimens are all in flower. I have not seen the fruit.

Hab. Barren summits of the Rocky Mountains, on the eastern side of the ridge, lat. 52° to- 55°-., Drum-?
mond.—This plant has been well described by Sir James E. Smith, from Siberian specimens, and by Schlechtendal
from those gathered by Chamisso, in the Bay of St. Lawrence, on the coast of Kamschatka. Our
plants are from three to four inches in height, offering no variation in the numerous specimens gathered by
Mr. Drummond. The species is allied on the one hand to R. nivalis, Eschscholtzii, and, I may even add, to
R. Sdbinii, but differing in the constantly pedatifid leaves; and, on the other hand, I possess some single-
flowered specimens of R. affinis, which show a great affinity with it. Ripe fruit I have not seen.
