Evergreen trees and shrubs, found in North America, in the south- 

 east and the north-west, and in Japan, from whence most beautiful 

 hardy species and varieties have been introduced. 



The generic name Retinispora (often falsely written Retinospora) was 

 chosen by Siebold and Zuccarini for the Japanese species Ch. ohtusa and 

 Ch. pisifera, but as there is so little difi'er^nce this generic name has 

 been almost abandoned on the Continent, where now the above name 

 is predominant.
