COMMON TYPES OF WALNUT IN CALIFORNIA 
The Persian (commonly called English) walnut is widely grown in California, but as the 
early groves were all planted from seed, there are now a great many different types 
of nuts produced. This illustration shows the wide variation among these types. 
Efforts are now being made to organize the industry on a sounder base, by eliminating 
the worthless types, and introducing new ones which shall combine as many good 
points as possible. (Fig. 4.)
