Reeves' Spir^a (S. Reevesiana, S. lanceolata of some), 

 is one of the best flowering shrubs in cultivation. It has 

 a graceful, slightly drooping habit, and narrow, pointed 

 leaves of good color. The plant in June is covered with 

 clusters of pure-white flowers, making it highly attrac- 

 tive, H. 



Fortui^e's Spiraea {8. callcsa). It was at one time 

 supposed that this, S. callosa, and 8. Fortunei were the 

 same, but they are now regarded as distinct. Fortune's 

 name has become in the catalogues well fixed to this 

 plant, though it really belongs to .S'. Fortunei. All con- 

 fusion may be avoided by the use of the scientific name, 

 8. callosa. It is a fine species, bearing large corymbs of 

 rose-colored flowers for a long time. There is a white- 

 flowered variety which is more dwarf, and flowers at in- 

 tervals all through the season, H.

 S. Eximia of the catalogues, are at most varieties of 

 this). A fine species of upright habit, with long panicles 

 of rose-colored flowers in June, G. 



Plum-leaved Spir^a, Double, {8. primifolia, fl. pi.), 

 a hio-hly esteemed shrub from Japan, densely covered in 

 spring with double-white, daisy-like flowers. Its fine, 

 glossy leaves assume brilliant tints in autumn, G. 



Thunberg's Spir^-V {8. Thunlergii), a distinct and 

 remarkably fine species of picturesque habit. The 

 delicate, very narrow leaves, are of a tender green color, 

 w^hich in autumn change to reddish shades. Produces 

 an abundance of white flowers in May, H. 



Goldek-leaved Spir^a (a variety of 8. opuUfolia, 

 as it was formerly called, but the species is now placed 

 in the genus Keillia). A robust variety of the wtII- 

 known Nine-bark ; the-foliage has a yellow tinge espec-
