The third district comprehends the higher regions of the Cascade 
and Rocky Mountains, including the Galton Range, which lies near 
the latter, between the Tobacco Plains of the Kootenay and the 
Flathead River. The highest points at which we had an opportu- 
nity of collecting were on the Cascades at 7500 feet, and on the 
Rocky Mountains at about 8300 feet. 
The following is a list of plants which were found to be almost 
if not entirely confined to those mountains, at a height of at least 
4000 feet above the sea, with their geographical distribution :—
