Hab. Common on the high grounds around the Kettle Falls of the Columbia, and on the Hocky 

 Mountains. Douglas. — S. ranuncul /folia differs in so many points from all the known individuals of the 

 genus, that we scarcely knoiv which to mention as its nearest ally : perhaps the Em-optean 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 arc di^dded, 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 Spiraea,

H.VB. Dry rocky situations upon the more elevated of the Rocky Mountains. Dnimmond. — 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. Druramond; the former foxind 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. Richer dsonii : 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 Sonnd. Messrs. Lay and 

 Co//ie.— This truly liaudsome" plant, the finest of the genus inth Tihicb we are acquainted, and meriting- 

 the name of "pidcherrima species^'* we are noiv satisfied is quite different from the S. Nelsoniana of Mr. Don ; 

 which however, ive reoret 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.
