Hab. North -West coast of America. Memies, in Herb, nostr. On the Great Rapids of the Columbia. 

 Lems (in Pursh). — Common between 40*^ and 50° of N. lat.; exclusively confined to the mountainous 

 woody country along the coast, which seldom exceeds 2^ or 2° 30" of long. Douglas; Dr. Scouler. Its 

 eastern station on the Columbia is four miles above the " Grand Rapids." Douglas. — This noble tree was 

 unquestionably discovered by our countryman Mr. Menzies, the first Naturalist who visited the coast where 

 it grows ; and it could not but be noticed by evei-y succeeding Botanist, for Mr. Douglas observes, " it is 

 one of the most graceful of trees in the country it inhabits, vai'ying from 40 to 90 feet in height, and from 

 6 to 16 feet in the circumference of its trunk. The broTiches are widely spreading ; the bark rough, brown j 

 the wood soft, but beautifully veined. It contains perhaps as much sap as any species, except A. sacckarinumf 

 but is not used by the natives. The flowers are yellow, very fragrant, appearing in April and May. It will, 

 al some future time, constitute one of our most ornamental forest-trees in England."
