For a discussion of this form and its relation to the type species, 

 see Hall, I.e., pp. 197-198. The type locality for S. gracilis Eastwood 

 is ''below timber line on the trail from East Lake to Harrison's Pass," 

 Tulare County: here the ordinary paniculate inflorescence is reduced 

 to a simple few-flowered raceme.

 p. 258).

Specimens examined. — Mt. Rose, 10,500 feet. Heller 10,214; Sonora 

 Pass, 10,000 feet. Brewer 1885 ; Ebbett's Pass, 8,000 feet, Brewer 2028. 



At my request, Mr. J. F. Macbride, of the Gray Herbarium, ha^ 

 very kindly reexamined the material in the Gray Herbarium and 

 confirms the assignment of Heller 10214 and Brewer 2028 to this 

 species. In regard to the latter number, however, there seems to be 

 a confusion since Dr. H. M. Hall, of the University of California, 

 informs me that the duplicate of this number in the University set 

 of the State Survey's collections contains Druha Lonmoni.
