 Suppl., p. 343. Torr and Gray, Fl. N. Am. vol. i. p. 500. 



A magnificent hardy Evening Primrose, admirably adapted 

 for a rockery, conspicuous for its bright green foliage, the 

 ribs and petiole of which underneath are often of a blood-red 

 colour ; as also for the very large and handsome flowers, fully 

 four inches in diameter, which are produced in succession, 

 and in considerable numbers. It is a native of the Kocky 

 Mountains, in Upper California, where it was discovered by 

 Nuttall in 1842; and it has also been found in the Snake 

 march 1st, 1870.
