This is essentially a Rocky Mountain plant, occurring in one or other of its forms in 

 New Mexico, Colorado (where I gathered it last year, near Canyon City), California 

 Arizona and Oregon. The forms which pass under the name of C. ligustidfolia might be 

 referred as varieties of C. Virginiana. Mr. James suggests that the eastern plant [C. Virgi- 

 niana) is a descendant of the western one {C. ligxslicifoUa), and that the latter may have its 

 nearest relatives in the highlands of India, but I know no Indian species resembling it. 



Dr. G-eorge Dawson's specimen from Sand Creek, Columbia Valley, with nearly 

 smooth, broadly ovate, subcordate, tri-lobed leaflets, may be T. and Gr.'s var. ft- brevifolia.

On the west side of the Rocky Mountains, near the sources of the Columbia. 

 Douglas, in Hook., FL, B.-A., (quoted as the Oregon in Torr. and Gr.) Judging from the 

 course of the Columbia River and Douglas's route as laid down in Hooker's map, the 

 locality of this plant would be in the neighbourhood of Mount Brown, near 52 north 

 latitude. It does not appear to have been found in British America by any other collector ; 

 but several localities are given for the Rocky Mountains of the south. Mr. James thus 

 sketches its distribution : — •" A mountain western species, strictly confined, so f;iT as 

 known, to the Rocky Mountain ranges, and extending from Central Colorado, at Middle 

 Park, Clear Creek Canyon (middle elevations), and in the Wahsatch and Uinta Mountains 

 of Utah, at 6,000 or 7,000 feet, to Fort Ellis, and the Yellowstone in Montana, at Snake 

 River Valley. Teton Mountains (11,000 feet) and Flat Head River Valley in Northern
