DESCRIPTIVE LIST OF FLOWERING SHRUBS. 471 
immense numbers which delight to revel in its sweets. 
This shrub propagates itself too fast, as it throws up its 
suckers in great profusion, and makes itself quite too com- 
mon; otherwise it would be a desirable plant for the 
shrubbery. 
8. Reevesidna.—Mr. Reeves’s Spirzea.--We consider 
this one of the most elegant and desirable species of the 
whole genus. The flowers are of a snowy whiteness, 
produced in clusters, the whole length of its graceful, 
arching stems, which, intermingled with the handsome fo- 
liage, produce a pleasing effect. The shrub is delicate in 
its growth, about four feet high, and flowers in June. It 
is propagated by cuttings, layers; and suckers. 
8. airefélia.—This is a very delicate species which we 
have in our collection, with exceedingly graceful foliage, 
with small heads of white flowers; two or three feet high. 
§. levigata.—Smooth-leaved Spirza.—This species has 
smooth lanceolate leaves, without serrature or notch, The 
flowers are white, in compound racemes, somewhat fra- 
grant. It is not very showy, but, in a collection, makes 
up a variety; about two or three feet high. 
§. trilobita.—Three-lobed-leaved Spirseea.—The leaves 
of this species are bluntly three-lobed, and toothed, or 
notched. The flowers are white, in stalked umbels, about 
three or four feet high. 
Altogether, we do not know any genus of plants where 
the foliage is so diversified. When grouped together, 
they make a fine appearance, either in flower or foliage. 
There are many other species that have not come under 
our observation, which, no doubt, are as valuable for the 
shrubbery as those described.
