1. E. Guutinosum Benth. Corolla pale or 
bluish.—Chaparral and chemisal. Summer. 
An exceedingly variable species. The res- 
inous exudation of the fyoung branches and 
leaves has a bitter, somewhat aromatic taste.

mild diuretic, and was used as such by the old 
‘inbabitants of California. At present consid- 
erable quantities are exported, partly for me- 
dicinal purposes, partly as a harmless and 
agreeable substitute for hops in brewing cer- 
tain varieties of beer, especially porter.
