Hab. Common on the high grounds around the Kettle Falls of the Columbia, and on the Rocky
Mountains. Douglas.—S. ranunculifolia differs in so many points from all the known individuals of the
genus, that we scarcely know which to mention as its nearest ally : perhaps the Europæan S. granulata.
The leaves are deeply tripartite, a very unusual character in the broad-leaved Saxifrages ; and this, together
with the mode in which the segments are divided, and the long petioles, give them the appearance of some
species of Ranunculus ; while the arrangement of the flowers reminds us of those of the genus Spiroea.

Hab. Dry rocky situations upon the more elevated of the Rocky Mountains. Drummond.—S. Jamesii
is certainly amongst the most beautiful of its tribe, and appears to have been seen in a growing state by no
other Botanists except Dr. James and Mr. Drummond; the former found it in more southern latitudes upon
the same ridge of mountains, and it has been well characterised by Dr. Torrey in the work above quoted.
Its affinity is unquestionably with S. Richardsonii : it has the same habit, nearly the same foliage, and
similarly acute petals, but the whole plant is much smaller ; its more copious glands are almost entirely
confined to the racemes and calyces ; the petals are smaller, more decidedly unguiculate, the stamens double
in number, and the anthers are oblong.

Hab. Arctic Sea-shore between the Mackenzie and Copper-Mine Rivers, (not Rocky Mountains, as stated
by mistake in the “ Botany of Beechey’s Voyage.”) Dr. Richardson. Kotzebue’s Sound. Messrs. Lay and
Collie.—This truly handsome plant, the finest of the genus with which we are acquainted, and meriting
the name of “ pulcherrima species,” we are now satisfied is quite different from the S. Nelsoniana of Mr. Don ;
which, however, we regret to say, we still know only from description. It is, indeed, in habit, in the presence
of copious glands, and more especially in the extremely acute petals, unlike any of the species of the genus,
except the; preceding, S. Jamesii ; and the two might form a distinct little groupe.
