RoUingstone is an old Americana sort which has been kept in culti- 

 vation chiefly because it is of very good qiiality for one of its species. The 

 fruit is rather dull in color and small but not unattractive in appearance; 

 the plums are little troubled by either the brown-rot or the plum curculio 

 and ship very well because of the tough skin. The tree is dwarfish with 

 a crooked trunk, shaggy bark, unkempt top and very twiggy — a typical 

 Americana and most difficult to grow into a good orchard plant. The 

 variety is characterized by long, conspicuous stamens, stigmas frequently 

 defective and by very large leaves. The variety has little or no value 

 in New York.
