A Seedless White Sapote. (Casimiroa sp., S. P. I. No. 47957.) 



When undertaking the improvement of a cultivated fruit, one of the chief aims of horticul- 

 turists seems to be the development of seedless forms. The above illustration shows a 

 seedless white sapote, grown by Mr. I. L. Collins at Orange, Calif. It is not rare for trees of 

 this species to produce such fruits, but it is not yet certain that grafting or budding will 

 perpetuate the characteristic; it is quite possible that seedlessness, in this species, may often 

 be due to defective pollination. (Photographed by David Fairchild, Orange, Calif., October 

 10, 1919; P25706FS.)
