 Linnets Panax comprises Panax trifoliatum, P. quinquefolium and 



P. fruticosum. The last, however, is a species of Nothopanax with double 

 pinnate leaves and valvate petals. Many authors like Houttuyn, Jussieu, 

 Willdenow, Aiton, Endlicher and others have followed him. But from 

 the time of A. P. de Candolle many species of the Nothopanax-type have 

 been added to the genus and its characters gradually have come to 

 represent the conception of Decaisne & Planchon or Bentham & Hooker. 

 Seemann who made a thorough study of the Araliaceae known at his time 

 reverted to the Linnean conception of the genus and improved it by ex- 

 cluding from it Panax fruticosum. Harms has followed him and this is 

 really the best disposition.
