Locs. — As to its distribution in California, Mer- 

 tensia ciliata var. stomatechoides occurs both on the 

 west slope of the Sierra Nevada and on the east side. 

 On the west slope, it tends to keep, for the most part, 

 to the higher easterly plateaus or valleys or peaks. 

 No wholly trustworthy record has been established as 

 yet for the Coast Eanges. The follomng stations are 

 for the Sierra Nevada region. Sierra Nevada, west
