A very common plant, according to Mr. Douglas, in 
open places, in mountainous Pine woods, in dry sandy 
soils, between Salmon River and the Kettle Falls in the 
Columbia, in the 48° north lat. ; also in the valleys of the 
Rocky Mountains, in similar soil, at an elevation of 7000 
feet above the level of the sea: flowering in July and 
August. x 
It was introduced by its discoverer in 1827, in the 
autumn of which year it flowered in the Garden of the 
Horticultural Society, where our drawing was made. 
It is by no means one of the handsomest of the genus; 
but it is a truly distinct species.
