In the Synoptical Flora and in Piper's Flora of the State of Washington the distribution of Ceanothus sanguineus, Pursh is given as from Brit. Columbia to N. California and Idaho. Howell gives the same range but extends it eastward to Montana. Rydberg, in the Flora of Montana, says it occurs only on the western slope of the main range of the Rocky Mountains. Coulter's Manual, 1st. Ed., credits it to the region of the Missouri and its tributaries, but it is not given a place in the 2nd edition. Pursh, who first described it from material collected by Lewis, gives it as "Near the Rocky Mountains, on the banks of the Missouri;" in so far as this statement by itself is concerned, it might mean either the eastern or western slope of the Rockies or both; I have not access to any records that might determine the point in question. The plant, however, has been considered to belong exclusively to the northwestern region west of the main range of the Rocky Mountains. Its discovery, therefore, in the Keweenaw Peninsula, in Michigan, is of more than local interest. I first collected it in fruit in August, 1S86, near Copper Harbor. At that time, being young in years and botanical experience, my main object was to make each species I found agree with some one of those enumerated in Gray's Manual; so it naturally found a resting place in the species cover of C. Americanus, where it remained forgotten until 1914. Having in that year had occasion to examine critically my material of the eastern species 1 at once observed that the Keweenaw plant was not C. Americanus. An investigation convinced me that it was either C. sanguineus or a new species. On a trip to the Lake Superior region early in July of this year (191...
