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. 



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.
