Collected in gravelly soil in the Olympic Mountains at 1,650 meters altitude, August 30, 

 1898, by J. B. Flett (no. 815). The occurence ol the subspecies so far detached liom its 

 related species of the Ro<ky Mountains seems remarkable. It may be expected to turn up 

 in the Cascade Mountains, possibly with intermediate character of pubescence. The type is 

 deposited in the National Herbarium.
