2. Synthyris pinnatifida lanuginosa subsp. nov. 
Densely appressed white-woolly. Otherwise as in the species. 
Collected in gravelly soil in the Olympic Mountains at 1,650 meters altitude, August 30, 
1898, by J. B. Flett (no, 815). The occurence of the subspecies so far detached {rom its 
related species of the Rocky 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.
