Bay. X)r. Richardson; Vrummond; Douglas.^-The general aspect of this plant, particularly its foliage, is 

 very similar to that of R. alpinus, but the flowers are very different, decidedly apetalous, the anthers are 

 much smaller, and the berries larger and much more pulpy.

Hab. North-West America. Nootka. Mr. Menzies. Banks of Kooxkoosky. Lewis, (in Pursh.) 

 Common on the banks of the Columbia, in dry soils near the outskirts of Pine-forests. — If this be the R. 

 alnifolius of Pursh, as is very probable, judging not only from the similarity of the leaves to those of our 

 Alder, but also from the country where Mr. Lewis found his specimens, (very near to the Columbia,) the 

 leaves are not " cordate at the base," nor are the peduncles " twice bifid."

Hab. North-West coast of America. Mr, Menzies. — This I have long possessed from its estimable discoverer, 

 who found it not only on the banks of the Columbia River, but in California. The flowering specimen is 

 from the latter country; the one in fruit from the former. I ought to observe, however, that there are some 

 discrepancies between the two : the one from the Coli«ttbia having larger and greener foliagw, and its 

 younf' leaves are more decidedly velutinous beneath; so that it is possible the two may be distinct.
