very appropriately named, will be found to succeed best 

 •when planted in exalted positions, and light, though rich, 

 strong soil. They are easy of propagation, and self-sown 

 seedlings are not uncommon. 



Citharexylum. See Rhaphithamnus. 



Citrus (Rutaceae). 



Z» Citrus tbifoliata. — Japan, 1869. This is a singular

 even in a flowerless state. In July and August the dense

 Wood. North America, 1812. This is a handsome 

 deciduous tree that does well in many parts of the 

 country, and is valued for the rich profusion of white 

 flowers produced, and which are well set off by the finely- 

 cut pinnate leaves. It is a valuable tree for park and
