Dr. Hooker, who has admirably described this most striking Ant- 

 arctic plant, recognises it as "certainly of a different genus from 

 Aralia proper," but hesitates fully to separate it before the order shall 

 have undergone the revision which it so greatly needs. He doubts 

 whether the petals are really valvate in sestivation,— a doubt which 

 may be readily solved, since in specimens with flower-buds, collected 

 and kindly furnished by himself, they are seen to be decidedly imbri- 

 cated. This character, added to the acetabuliform fruit, and the 

 styles fewer than the petals, must surely exclude the plant from 

 Aralia, however that genus be limited.
