A Californian perennial, raised in the garden of the Hor- 
ticultural Society bom seeds picked off some of Mr. Douglas' 
dried specimens. In its native country it/appears to be a 
stout branching plant, béaring a profusion of small, white 
and purple flowers: but when cultivated it has been found 
so tender and difficult to mañage, that little of its native 
beauty is developed. | NI
