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 oecur.
