 in the Canadian Zone at 9000 ft. alt. on the Devils Backbone and on Tele- 

 graph Peak Summit. (Nos. 1414, 1592, 1603.) 



Phacelia curvipes Torr. var. pratensis. All my collections were of the small flow- 

 ered typical plant but Dr. Hall collected in Swartout Valleythe large flowered 

 form that is referred to this variety by Brand (Pflanzenr. IV, 251 : 115 

 (1913).

Phacelia Davidsonii Gray. Form macrantha (Parish) Johnston, comb. nov. 

 P. Davidsonii Gray. var. macranlha Parish. We did not see any plants 

 that were referable to this large flowered form but according to Brand 

 (Pflanzenr. iv. 251 :116 (1916)) Dr. Hall collected it in our limits. 



The plant concerned here differs from typical P. Davidsonii only in its 

 large flowers (15-22 mm. wide). As there appears to be no relation of 

 distribution with the occurrence of this variation and since a very com-
