A Californian perennial, raised in the garden of the Hor- 

 ticultural Society from seeds picked off some of Mr. Douglas' 

 dried specimens. In its native country it appears to be a 

 stout branching plant, bearing a profusion of small, white 

 and purple flowers : but when cultivated it has been found 

 so tender and difficult to manage, that little of its native 

 beauty is developed.
