PRCEPARTURIENS. 



A French variety introduced by Gillet, which was planted quite ex- 

 tensively in central and northern California some years ago. The nut 

 is rather small and the variety can no longer be considered worthy of 

 commercial planting. 



SANTA BARBARA SOFT SHELL. 



This is the prevailing type of seedling walnut of southern Cali- 

 fornia, originated by Joseph Sexton. Its history has been described at 

 length on page 173. The trees and the nuts which they bear vary 

 to a considerable extent among themselves, but yet are mostly of the 

 same general type. The nuts are usually of good size, easily cracked 

 in the fingers, and of excellent flavor and quality. The trees come out 

 fairly early in the spring and usually produce an abundance of pollen. 

 This type is particularly well adapted to southern California, except for 

 its susceptibility to walnut blight and the variation in trees produced by 

 seedling propagation through several generations. Some of the varie- 

 ties, like Placentia Perfection, Discher's Prolific, Neff, El Monte, Pride 

 of Ventura and others, obtained by selecting individual trees of this 

 type, are most excellent in every way except for the susceptibility to 

 blight or individual minor defects. An ideal variety may yet be found 

 among the many hundreds of thousands of trees of this type now grow- 

 ing in southern California. 



SANTA ROSA. 



A variety first introduced by Luther Burbank and considered at one 

 time of great promise on account of its productiveness. The nut is 

 rather small, however, and has proven to be one of the most susceptible 

 of all varieties to the blight. Consequently, its further planting cannot 

 be considered advisable. The Payne tree at San Jose is top-worked 

 with this variety and bears immense crops of nuts. 



SEEDLING (see Santa Barbara Soft Shell). 



SEROTINA. 

 A French variety introduced by Gillet. Of no commercial importance. 



SOFT SHELL (see Santa Barbara Soft Shell). 

 TREYVE. 



A French variety of the Mayette type introduced by Gillet. But 

 very little planted in California. This is a beautiful nut, especially on 

 account of its almost pure white meat. Mr. Ely Hutchinson, of Concord, 

 has the variety in bearing. Probably not commercially important on 

 account of poor production.
