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 j^rofusion, and makes itself quite too com- 

 mon ; otherwise it would be a desirable plant for the 

 shrubbery. 



S. Reeresiana. — Mr. Reeves's Spiraea. — We consider 

 this one of the most elegant and desirable species of the 

 whole genus. The flow^ers are of a snowy wdiiteness, 

 produced in clusters, the whole length of its graceful, 

 arching stems, w^iich, intermingled with the handsome fo- 

 liage, produce a ple:ising effect. The shrub is delicate in 

 its growth, about four feet high, and flowers in June. It 

 is propagated by cuttings, layers, and suckers. 



S. airaefolia. — This is a very delicate sj^ecies which we 

 have in our collection, with exceedingly graceful foliage, 

 with small heads of white flowers ; tw^o or three feet high. 



S. laevigata. — Smooth-leaved Spiraea. — This species has 

 smooth lanceolate leaves, without serrature or notch. The 

 flowers are w^hite, in compound racemes, somewhat fra- 

 grant. It is not very shovv'v, but, in a collection, makes 

 up a variety ; about two or three feet high. 



S. trilobata. — Three-lobed-leaved Spiraea. — The leaves 

 of this species are bluntly three-lobed, and toothed, or 

 notched. The flow^ers are wdiite, 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 fohage. 

 There are many other species that have not come under 

 our observation, which, no doubt, are as valuable for the 

 shrubbery as those described.
