Distribution. Valley of the Yukon River near Dawson, Yukon, Vancouver Island, 

 and southward near the coast of Washington and Oregon, and on the western slope of 

 the Sierra Nevada and on the coast ranges to southern California, ranging from the sea-

 Soccoro County, and Santa Fe, Santa Fe County) ; in Colorado (Buena Vista, Chaff ee 

 County, Alice Eastwood). Passing into var. caudata Sudw., distinguished by its caudate- 

 acuminate leaves green on both surfaces, and by its bright yellow or orange-yellow branch- 

 lets, and ranging from northeastern Oregon and eastern Washington through Idaho, and 

 from northern Wyoming to southern Colorado, Utah and Nevada. 



A variety (var. lancifolia Bebb), differing from the typical S. lasiandra in the gray or 

 rusty villose pubescence covering the branchlets during their first and sometimes their 

 second season and the lower surface of the young leaves, is distributed from Dawson in the 

 valley of the Yukon River southward to the valley of the upper Nesqually River, Wash- 

 ington, to the valley of the Willamette River (Salem, Oregon), to Santa Cruz, Santa Cruz
