Pursh 's actual type specimen now preserved in the Philadelphia Academy is certainly 

 the plant generally accepted under this name and not the same as B. repens Lindl. as has 

 been claimed. Lewis's specimens of this and of B. nervosa were collected at the Great 

 Rapids [Cascades] of the Columbia, in which vicinity B. repens seems not to occur.
