1 This variety is incorrectly named. It appears to be identical with Up-to-Date rather than White Rose. 
» The stock grown in Maine under this name belongs to the Rural group and is evidently distinct from 
the Sensation referred to the Green Mountain group in the report of the Committee on Varietal Nomenclature 
and Testing. (26).
