A new hardy annual, native of California, whence it was 

 introduced by the Horticultural Society in 1834. It 

 flowers in May and June, if sown very early in the spring 

 or in the previous autumn, and forms a pretty o^ay mass of 

 yellow in the beds of the flower garden. It seeds profusely. 



The characters of the genus Lasthenia have not yet 

 been published ; the name is employed in the manuscripts, 

 of Professor De Candolle for another species,! wliich is 

 also in our gardens, but wliich is rather less ornamental 

 than the present. 



* An unexplained manuscript name of Professor De Candolle.
