wall profusely. Dr. Masters calls it undoubtedly one of 
the best flowering shrubs, and adds that it is hardy at 
Combe Wood, but that it must not be thence inferred that 
it would be so in less propitious localities. For my own 
part I do not doubt that in any part of England a severe 
winter would kill most plants that grow in so hot a country 
as Canton, and I follow Dr. Lindley in regarding this as a 
greenhouse plant. 
C. Mastacanthus was introduced by Fortune from China, 
where he found it wild near Canton, Chusan, and Koo- 
lung-soo. We have it also from Hongkong and Foochow ; 
and it is common in Southern Japan in fields, rocky places, 
and on the mountains. The specimen here figured flowered 
against a wall in Kew Gardens in October last. Its second 
introduction is due to Mr. Veitch’s collector, Mr. Maries.
