366 SYSTEMATIC POMOLOGY. 



great uniformity, and the shape changes. The seedlings of this 

 species usually develop only male flowers during the first three 

 years of growth. Later some pistillate flowers appear. The select 

 varieties are supposed to be perfect in flower, but increased ex- 

 perience has shown the gain in mixed planting of varieties, as 

 with most highly developed fruits; but when varieties are mixed in 

 planting the effects of cross-pollination appear on the fruits to a 

 remarkable extent. Berckmans, of Georgia, says : " This variation in 

 the color of the flesh has caused some confusion in reaching a correct 

 nomenclature." The heavy and continuous bearing of the Japanese 

 varieties has so retarded the growth that rather close planting is 

 recommended not exceeding twenty by twenty-five feet each way. 

 The Texana varieties are still smaller in growth and can be planted 

 closer. Under cultivation the varieties of the Virginiana species 

 make large trees with great spread of top, and should be planted 

 accordingly, and the same is true of the Asiatic varieties of the Lotus 

 type when introduced. Propagation by crown-grafting on trans- 

 planted native seedlings, and top- working on native stocks is given 

 in Section 219 briefly. The writer's experience and observation lead 

 to the belief that it is quite as easy to bud or graft as the pear, plum, 

 and cherry, if the side-graft plan is adopted (86).

 but quality improves as it becomes soft. Season, September to
