Here is another hardy Ceanothus, allied to, but very distinct 
from, C. velutinus, figured at our Tab. 5165, recently imported to 
our gardens and shrubberies by Messrs. Veitch of the Exeter and 
Chelsea Nurseries, from the Oregon territory, through their col- 
lector, Mr. William Lobb. It was first detected by Douglas in 
woods of the Oregon, frequent from the Blue Mountains to the 
sea; found there also by Nuttall and Tolmie, and Dr. Scouler. 
I had mistaken it, in my Fl. Bor. Am., for the C. sanguineus of 
Pursh, an indifferently described plant, and a native, it appears, © 
of more southern latitudes, near the. Rocky Mountains, on the 
banks of the Missouri, and which is said to resemble considerably 
the C. Americanus. C. Oreganus flowers in May, and bears co- 
pious lateral paniclés, which are entirely white. 
Descr. A shrub, four to twelve feet high, with dranches gla- 
brous, much tinged with red on one side. Leaves alternate, 
firm, subcoriaceo-membranaceous, two to two and a half inches 
long, petiolate, elliptical, obtuse, three-nerved, rarely subcordate 
at the base, serrated at the margin, paler beneath, where the 
young leaves are slightly pubescent. Petioles half to three- 
quarters of an inch long, pale green, with a pair of deciduous 
stipules at the base. Panicles axillary, often appearing quite 
lateral from the deciduous leaves ; their branches form dense
