Clarkia pulchella, Pursh. Native in stony ground 

 in Western North America. Much cultivated in British 

 gardens, and occasionally found as an escape in their 

 neighbourhood. 



(Enothera biennis, L. Common in North America 

 on river banks, lake margins, &c. In England and 

 many other parts of Europe it is locally abundant 

 as a naturalised plant, and is apparently perfectly 

 established in several places where the environments 

 suit it, such as seashores and sand-hills. It has long 

 been a favourite garden plant, and its presence is pro- 

 bably entirely due to this fact. 



(Enothera odorata, Jacq. Native of the stony pastures 

 of temperate South America. Cultivated in gardens 

 in England, and found on several occasions in a semi- 

 naturalised condition near villages and towns. 



(Enothera pumila, L. Native of North America. A 

 plant sometimes cultivated, and readily establishing 

 itself as a weed in and near gardens. 



(Enothera purpurea, Curt. Native of North America. 

 There is a specimen in the British Museum Herbarium, 

 recorded as a garden escape.
