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 gay mass of 
yellow in the beds of the flower garden. It seeds profusely. 
The characters of the genus Lasthenia have not yet

of Professor De Candolle for another species, which is 
also in our gardens, but which is rather less ornamental 
than the present.
