I have examined all the species of the genus at Kew, but have 

 not been able to find any thing like the present plant. There is a 

 specimen labelled C. sativa in the Herbarium at Hongkong, which 

 specimen is exactly the same as the Formosan plant, but quite 

 différent from the type of the named species.
