PIPER—FLORA OF THE STATE OF WASHINGTON. 289 
Range: British Columbia to north California. 
SPECIMENS EXAMINED: West Klickitat County, Suksdorf 1927, 95, 500, 501, 233; Dar- 
ling Mountains, lett 1136; Simcoe Mountains, Howell, June, 1879; Klickitat Hills, Gor- 
man, April, 1895. 
A variable species. Schulz’s subspecies are based entirely on characters of leaf outline, 
but these seem too variable to rely upon. Field study and large suites of specimens are 
necessary before the species can be satisfactorily understood.
