cultivated specimens from Lindley in the Gray Herbarium. The 
type was grown from seeds collected by Douglas ‘along the 
banks of the Columbia.”’ 
Douglas, however, collected P. Lewzsiz also as shown by a 
_ specimen in Herb. Gray. There can be no doubt as to the iden- 
tity of P. Lewzsit as the type in the herbarium of the Philadelphia 
Academy is in fine preservation. It was collected by Lewis, ‘on 
the waters of Clark’s River,’ July 4, 1806. Dr. Elliott Coues 
says this means “ Hellgate River, between Missoula, Mont., and 
the mouth of Big Blackfoot River, in Missoula county, Montana.” 
P. Lewisii ranges from the east slope of the Cascade Mts. of 
Oregon, Washington and British Columbia eastward to western 
Montana. We have not seen any specimen of it from west of the 
Cascade Mountains.
