a handsome tree. .51 /. pendula is a weeping variety, 

 and one of the best weeping-trees known. It should

 of securing good specimens. 



S. secundiflora is an American species with somewhat 

 larger blossoms of rich violet color. These appear in 

 June or early July. The leaves are more coriaceous and 

 glossy than those of the japonica, but this form is not so 

 hardy, and is not advised for northern planting. Its home 

 appears to be in the extreme Southwest. It is abundant 

 in Texas and Mexico, and is there a broad-leaved ever-

 a native of New Zealand, and has yellow flowers. It is a 

 beautiful half-hardy shrub suitable for planting only in the 

 Southern States unless afforded ample protection. It is 

 deciduous, and grows to a height of twelve feet.

 Japan, and was introduced into England as early as 1866,

 feet in height, and when grown on a wall has almost as
