A hardy shrub found by Mr. Douglas on the banks of 
the Columbia River, where it forms part of the underwood. 
It was raised many years since by the Horticultural Society, 
and has been extensively distributed. It is the latest species 
that flowers, grows from eight to ten feet high, and has 
almost a weeping appearance in consequence of producing 
numerous slender side shoots. 
The leaves are bright green, rather small, ovate, pointed, 
3-nerved at the base, and coarsely serrated. The flowers 
are large, pure white, in close bunches of from five to nine, 
are nearly scentless, and are produced in such great pro- 
fusion that this is one of the handsomest of hardy deciduous 
shrubs. The fruit is large, smooth, with the lobes of the 
calyx broad and nearly horizontal. 
It is readily known by its small deeply serrated leaves, 
its nearly superior fruit, its broad spreading calyx, and by 
the compact manner in which its flowers are arranged. 
It is a very showy shrub, growing in any soil, and very 
hardy, not having been at all injured by the severe winter 
of 1837-8. It flowers about the end of July, and may be 
increased from seeds or by cutting off the half-ripened shoots 
about August, when they strike as freely as the common
