A native of California, where the seeds were collected by 

 Mr. Douglas. It is a hardy herbaceous plant, propagated 

 by cuttings as well as seeds, and flowering from June to 

 October. The stems are rather woody, and if not supported 

 artificially fall upon the ground, and throw out a number of 

 lateral shoots. 



The upper part of the plant is sometimes furnished with 

 leaves so narrow as to be almost linear ; the lower has them 

 of an oblong lanceolate form ; so that a person unaware of 

 the circumstance would be apt to mistake portions of the 

 same individual for different species. 



Drawn in the garden of the Horticultural Society, where 

 the plant grows in common garden soil.
