— 
A pretty annual, not exceeding a foot in height, and 
flowering during nearly the whole summer, from the end 
of May to the beginning of October, during which period 
it produces a succession of blossoms. These are not so 
shewy as those of many other species, but they are exceed- 
ingly neat, the vexillum being pure white, and the ale 
deep blue. 
Found by Mr. Douglas, in the interior of the country 
about the Columbia river, from Fort Vancouver to the 
branches of Lewis and Clarke’s river; always upon dry 
gravelly soils, especially under the shade of trees, in the 
open plains.
