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



When uiidLTiakinj; the i]ii])iovemfiit of a cultivated fruit, one of tlie 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 spec-ies to produce such fruits, but it is not yet certain that grafting or budding will 

 perpetuate the characteristic: it is auite po.ssible tliat seedlessness, in this species, may often 

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