The distribution of this plant is thus seen to be from Shasta 
County to northern Lower California, the occurrence at Roosevelt 
Dam, Arizona, being certainly due to a casual introduction 
of seed from California. Variations are not particularly well- 
marked, except in two cases, as indicated below:

Depressed, 1 dm. tall, with decumbent branches and short
