? OEnothera Jepsonu Greene, Fl. Francis. 211. 1891. 
Throughout the United States, east of the Rocky Mountains, 
ranging from sea-level to about 650 meters on various mountains. 
The geographic range of O. dzennis is not as extensive as has 
been supposed. The species proper ranges westward only to the 
Mississippi River. In the area from the Mississippi River 
to the Rocky Mountains it is represented by a closely related 
form clothed with strigose pubescence; this form might be 
separated as a variety or even a species, As far as I can learn, 
it has not been found west of the Rocky Mountains. Prof. 
Greene described OZnothera Jepsomi* from California, but later 
* Fl. Francis. 211.
