78 BOTANICAL INFORMATION. 
Has. Near springs of the Rocky Mountains about the 
sources ofthe Columbia, Douglas, Drummond. Blue Moun- 
tains of Oregon, Douglas. Banks of streams, Upper Ore- 
gon, 10—20 feet high, very often shrubby ; more elevated 
in the lower regions, Geyer. (n. 616).—My first specimens 
of this, both from Douglas and Drummond, being only 
young flowering branches, I was unable to give an opi- 
nion respecting the species. Since the publication of the 
Flora Boreali-Americana, 1 have received good fructified 
specimens, gathered during poor Douglas' last journey in 
the Blue Mountains ; and now I possess flowering and fruit- 
ing specimens from Mr. Geyer, all of which clearly prove 
this to be a new and most distinct species, totally unlike 
A. grandidentatum of Nuttall, to which Messrs. Torrey and 
Gray have, with slight doubts however, referred it. Our — 
figure will, we trust, satisfactorily show the characters of this - 
species, which has a good deal the flowers of A. circin- 
natum, while its leaves more resemble those of A. rubrum : 
but it is in other respects very different from both.
