19231 WILSON, THE HORTENSIAS 241 



This form has pink, more or less toothed ray-flowers, otherwise it is 

 very similar to the wild form. Of the vernacular names cited by Siebold 

 & Zuccarini only "Gakuso" is applicable to this plant. In gardens today 

 the plant generally cultivated under the name of H. japonica is not Sie- 

 bold's plant but is the form rosalba of H. serrata DC. which is the "Beni- 

 kaku" of the Japanese. Siebold and Zuccarini applied this vernacular 

 name among others to their H. japonica and it is probably this that has 

 lead Japanese botanists astray in the identification of Siebold's species.
